Description

Technical Field

[0001] This invention relates to a method for evaluating the function and morphology of the upper eyelid. Background Technology

[0002] Upper eyelid surgery is a common surgical procedure for correcting problems such as single eyelids, puffy upper eyelids, sunken upper eyelids, ptosis, and loose upper eyelid skin. Traditional evaluation methods mainly rely on static appearance indicators, which have the following shortcomings: the evaluation indicators are singular, focusing only on the position of the upper eyelid margin, and cannot quantify issues such as abnormal eyebrow position, frontalis muscle compensation, and visual field obstruction; individual anatomical differences are not considered, resulting in large deviations in measurement results; only static morphology is assessed, ignoring the dynamic balance of the upper eyelid, the dynamic balance of the eyebrow, and the overall facial muscle tension network. Therefore, there is an urgent need for a standardized, quantifiable method for evaluating upper eyelid function and morphology that considers both static and dynamic aspects and can calibrate for individual differences. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for evaluating the function and morphology of the upper eyelid.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] A method for evaluating upper eyelid function and morphology includes the following steps:

[0006] Step 1: The patient sits in a natural position with both eyes looking straight ahead without any external intervention;

[0007] Step 2: Take standardized still photos of the patient before and after the operation;

[0008] Step 3: Enlarge the standardized static photos taken before and after the operation proportionally, using a uniform corneal diameter as the reference.

[0009] Step 4: Mark the positions of the pupil midline, the lower edge of the eyebrow, the skin fold edge, the upper eyelid margin, and the corneal light-reflecting point on the enlarged photograph;

[0010] Step 5: Measure the following three distance indicators along the extension line of the pupil midline:

[0011] The distance D2 between the lower edge of the eyebrow and the corneal light-reflecting point;

[0012] The distance D3 between the limbus fold and the corneal light-reflecting point;

[0013] The distance D1 between the upper eyelid margin and the corneal light-reflecting point;

[0014] Step Six: Calculate the postoperative and preoperative differences of the three indicators D2, D3, and D1 respectively. Use the differences of the three indicators before and after surgery for the same patient to comprehensively evaluate the effects of upper eyelid lifting, eyebrow compensation, double eyelid shape, and visual field improvement.

[0015] As a preferred method, the distance D2 between the lower edge of the eyebrow and the corneal light-reflecting point is used to reflect the eyebrow position and the state of frontalis muscle compensation. A decrease in D2 after surgery relative to the preoperative position indicates that the eyebrow body has fallen back to the resting position and the frontalis muscle compensation has been relieved.

[0016] As a preferred method, the distance D3 between the skin fold and the corneal light-reflecting point is used to reflect the shape of the double eyelid and the degree of visual field obstruction. If the postoperative D3 is better than the preoperative D3, it indicates that the visual field obstruction has been relieved or eliminated.

[0017] As a preferred option, the criteria for determining the relief of visual field obstruction are: postoperative D1 is within the range of 3.5mm to 4.5mm, and postoperative D3 is greater than postoperative D1; at the same time, D2 is smaller than preoperatively, indicating that the eyebrow has returned to the resting position and the compensation of the frontalis muscle has been relieved.

[0018] As a preferred method, the distance D1 between the upper eyelid margin and the corneal light-reflecting point is used to reflect the overall position of the upper eyelid in its functional state. A positive difference between the postoperative and preoperative D1 indicates that the upper eyelid has been effectively lifted; a negative difference between the postoperative and preoperative D1 indicates that there was compensatory overcontraction of the levator palpebrae superioris muscle before the operation, and that the neuromodulation returned to normal after the operation.

[0019] Preferably, the uniform corneal transverse diameter is a preset standard corneal transverse diameter, which is 11 mm.

[0020] Preferably, the differences between the three indicators before and after surgery are used to verify the repair effect of the upper eyelid three-axis functional model. The upper eyelid three-axis functional model includes a support axis, a power axis, and a contour axis. The D2 difference corresponds to the repair effect of the eyebrow power system in the power axis; the D1 difference corresponds to the functional recovery of the upper eyelid power system in the power axis, including two adjustment modes: positive enhancement and negative regression. The negative regression is manifested as follows: when D3 < D1 and D1 > 4.5 mm before surgery, nerve impulses are compensatorily enhanced, the postoperative visual field is improved, and neuromuscular regulation returns to normal; the D3 difference corresponds to the repair effect of the contour axis.

[0021] As a preferred method, the evaluation method also includes: taking pre- and post-operative dynamic eye-opening videos to simultaneously assess the balance of the facial muscle tension network and determine the improvement in coordination between the eyebrows, eyes, and lower face.

[0022] Preferably, in step four, the positions of the pupil midline, the lower eyebrow edge, the skin fold edge, the upper eyelid edge, and the corneal light-reflecting point are marked manually or automatically by an image recognition algorithm. In step five, the measurements of the three distance indicators D2, D3, and D1 are measured manually or automatically by an image recognition algorithm.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention provides a multi-dimensional comprehensive evaluation, covering the complete functional and morphological system. This method can quantify the eyebrow position and frontalis muscle compensation status, double eyelid shape and visual field obstruction, levator muscle function and corneal exposure at one time by simultaneously measuring three indicators: D2, D3 and D1. This achieves a comprehensive evaluation of the function and morphology of the upper eyelid and makes up for the one-sidedness of traditional single-indicator evaluation.

[0025] 2. The pathological improvement of this invention is intuitively verifiable, and the evaluation mechanism can be quantitatively verified. Quantitative verification of D2 reduction can directly confirm that the eyebrow body has fallen back to the resting position and the frontalis muscle compensation has been relieved; D3 optimization can clearly indicate the relief of upper visual field obstruction and the improvement of double eyelid shape; D1 optimization objectively reflects the improvement of levator muscle function; the difference between the three indicators can directly correspond to and verify the repair effect of the support axis, dynamic axis and contour axis in the "three-axis functional model", meeting the postoperative efficacy verification needs of functional upper eyelid surgery;

[0026] 3. This invention takes into account both static measurement and dynamic assessment to achieve overall facial expression evaluation. Combined with dynamic eye-opening video, it can simultaneously evaluate the balance of facial muscle tension network, objectively reflect the coordination of eyebrows, eyes, and lower face, and break through the limitations of traditional methods that only focus on local static morphology. It is more in line with the clinical needs of functional oculoplastic surgery and facial expression evaluation.

[0027] 4. This invention is standardized and automated, making it suitable for clinical application. Marking and measurement can be done manually or using image recognition algorithms. The process is standardized and highly repeatable. It can be used for routine clinical assessments as well as as a standardized testing method for clinical research and academic analysis, promoting the transformation of upper eyelid evaluation from experience-based to precise and standardized.

[0028] 5. The evaluation results are accurate and reliable, providing a scientific basis for clinical decision-making. This method can output objective and quantitative evaluation data, which can accurately reflect the true state of upper eyelid function and morphology, providing scientific support for personalized assessment, effect judgment, and efficacy comparison, and improving the stability and credibility of the overall evaluation system.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings:

[0037] I. Three-axis functional model

[0038] like Figure 1 As shown, the blue area is the support axis 1, the red area labeled 21 is the upper eyelid power system, the red area labeled 22 is the eyebrow power system, the green area is the power direction 3, and the yellow area is the contour axis 4.

[0039] The functions of the support shaft, power shaft, and profile shaft are shown in Table 1 below:

[0040] Table 1

[0041]

[0042] The core structures of the supporting axis 1 include the orbital bone, tarsal plate width, and supporting ligaments. Its function is to provide a basic framework, revealing the mechanisms of individualized morphological differences and aging: orbital bone morphology varies among different races, sexes, and individuals. In the same individual, aging leads to orbital bone atrophy, volume loss, and ligament laxity—degenerative changes in the supporting axis that are the initiating factors for brow shortening (drooping of the lower brow margin) and subsequent dynamic compensation (displacement of the upper brow margin).

[0043] The core structures of Dynamic Axis 2 are the upper eyelid balance (levator palpebrae superioris and orbicularis oculi) and the brow balance (frontalis and depressor supercilii muscles, orbicularis oculi), whose functions are eyelid opening and closing and visual field compensation, and brow position and facial expression, respectively. Dynamic Axis 2 reveals an interconnected "dual dynamic balance system": the upper eyelid dynamic system responsible for eyelid opening and closing, and the brow dynamic system responsible for visual field compensation and facial expression. The two are closely coupled through the common orbicularis oculi muscle and adjacent skin and fascia tissues. The proposal of the "dual dynamic balance system" is a core deepening of the "triaxial functional model" at the dynamic level, providing a key theoretical tool for explaining brow-eye linkage and pathological compensation.

[0044] The structure of contour axis 4 consists of skin, ROOF, and orbital fat, and its function is to represent the appearance.

[0045] The differences between the three indicators before and after surgery were used to verify the repair effect of the upper eyelid triaxial functional model, such as... Figure 1As shown, the upper eyelid three-axis functional model includes a support axis 1, a power axis 2, and a contour axis 4; wherein, the D2 difference corresponds to the repair effect of the eyebrow power system 22 in the power axis 2; the D1 difference corresponds to the functional recovery of the upper eyelid power system 21 in the power axis 2, including two adjustment modes: positive enhancement and negative regression; and the D3 difference corresponds to the repair effect of the contour axis 4.

[0046] II. Measurement Steps

[0047] A method for evaluating upper eyelid function and morphology includes the following steps:

[0048] Step 1: The patient sits in a natural position with both eyes looking straight ahead without any external intervention;

[0049] Step 2: Take standardized still photos of the patient before and after the operation;

[0050] Step 3: Enlarge the standardized static photos taken before and after the operation proportionally, using a uniform corneal diameter as the reference.

[0051] Step 4: Mark the positions of the pupil midline, the lower edge of the eyebrow, the skin fold edge, the upper eyelid margin, and the corneal light-reflecting point on the enlarged photograph;

[0052] Step 5: Measure the following three distance indicators along the extension line of the pupil midline:

[0053] The distance D2 between the lower edge of the eyebrow and the corneal light-reflecting point;

[0054] The distance D3 between the limbus fold and the corneal light-reflecting point;

[0055] The distance D1 between the upper eyelid margin and the corneal light-reflecting point;

[0056] Step Six: Calculate the postoperative and preoperative differences of the three indicators D2, D3, and D1 respectively. Use the differences of the three indicators before and after surgery for the same patient to comprehensively evaluate the effects of upper eyelid lifting, eyebrow compensation, double eyelid shape, and visual field improvement.

[0057] Evaluation methods also include: taking pre- and post-operative dynamic eye-opening videos to simultaneously assess the balance of facial muscle tension and determine the improvement in coordination between the eyebrows, eyes, and lower face.

[0058] In step four, the positions of the pupil midline, the lower eyebrow edge, the skin fold edge, the upper eyelid edge, and the corneal light-reflecting point are marked manually or automatically by an image recognition algorithm. In step five, the measurements of the three distance indicators D2, D3, and D1 are measured manually or automatically by an image recognition algorithm.

[0059] III. Clinical significance of each indicator

[0060] The distance D2 between the lower edge of the eyebrow and the corneal light-reflecting point is used to reflect the eyebrow position and the state of frontalis muscle compensation. A decrease in D2 after surgery relative to the preoperative position indicates that the eyebrow body has fallen back to the resting position and the frontalis muscle compensation has been relieved.

[0061] The distance D3 between the skin fold rim and the corneal light-reflecting point is used to reflect the shape of the double eyelid and the degree of visual field obstruction. Postoperative D3 optimization (adjustment towards the ideal reference range) indicates that visual field obstruction has been alleviated or eliminated, and the double eyelid shape is becoming more natural. Clinically verified, the ideal reference range for D3 varies by race and gender: the ideal reference range for postoperative D3 for East Asian women is 6.0mm to 8.0mm; for East Asian men, due to differences in orbital bone and brow ridge morphology, postoperative D3 can be appropriately narrowed (e.g., 5.0mm to 7.0mm), aiming for no visual field obstruction and a natural double eyelid shape. Other ethnic groups can refer to the normal range of their respective populations for adjustment.

[0062] The distance D1 between the upper eyelid margin and the corneal light-reflecting point is used to reflect the overall position of the upper eyelid in its functional state. A positive difference between the postoperative and preoperative D1 indicates that the upper eyelid has been effectively lifted. A negative difference between the postoperative and preoperative D1, provided that the postoperative visual field has improved, the eyes can be opened easily, and there are no uncomfortable symptoms, indicates that there was compensatory overcontraction of the levator muscle before the operation, and the postoperative neural regulation has returned to normal.

[0063] The uniform corneal transverse diameter is a preset standard corneal transverse diameter, which is 11mm.

[0064] IV. Criteria for Determining the Removal of Visual Obstruction

[0065] The criteria for determining the relief of visual field obstruction are: postoperative D1 is within the range of 3.5mm to 4.5mm, postoperative D3 is greater than postoperative D1; at the same time, D2 is smaller than preoperatively, indicating that the eyebrow has returned to the resting position and the compensation of the frontalis muscle has been relieved.

[0066] V. Clinical validation data

[0067] This invention included 251 cases (499 eyes), 29 males (57 eyes) and 222 females (442 eyes), with a mean age of 33.68 years (range 18-81 years). Postoperative follow-up ranged from 6 to 24 months. Patients had easy eye opening and complete eye closing. Objective measurements are shown in Table 2.

[0068] Table 2 Comparison of upper eyelid triaxial function and morphological evaluation indicators before and after surgery.

[0069]

[0070] As shown in Table 2, D2 decreased significantly postoperatively, confirming the return of the eyebrow to its resting position and the relief of frontalis muscle compensation. With the repositioning of the eyebrow dynamic axis, the abnormal tension in the overall face was alleviated, resulting in a natural visual effect of improved coordination between the eyebrows, eyes, and lower face. Figures 4-7Postoperative D3 showed significant improvement, indicating relief of visual field obstruction and improvement in double eyelid shape. Postoperative D1 changes confirmed improved levator muscle function, and some patients with preoperatively higher compensatory D1 levels experienced a physiological decline postoperatively, reflecting the normalization of neuromuscular regulation.

[0071] Traditional assessment indicators (such as the distance between the upper eyelid margin and the corneal impression point, MRD1, measured under brow-pressed conditions) primarily reflect the efficacy of the levator palpebrae superioris muscle (dynamic axis) but are difficult to quantify functional visual field defects and brow-forehead compensation caused by skin laxity (contour axis abnormality). Therefore, this invention, guided by a "triaxial model," proposes simultaneously measuring "D2," "D3," and "D1" on standard photographs. Figure 2 , Figure 3 The procedure was used to systematically assess the upper eyelid condition. Clinical observation revealed that in some patients with severe skin occlusion and elevated D1 compensation preoperatively, their D1 values ​​returned to normal physiological levels after the occlusion was removed postoperatively. This phenomenon confirms that the support axis, contour axis, and dynamic axis are not isolated but rather have a dynamic and mutually causal relationship. As shown in Table 1, the significant shortening of D2 postoperatively (difference -2.09±2.07mm) is of core significance, objectively confirming the effective return of the eyebrow body to the resting position, which is the terminal effect of the frontalis muscle compensation. At the same time, the dynamic changes of D3 and D1 quantify the actual repositioning of the contour axis and dynamic axis (neuromuscular regulation function) after the abnormal coupling is decoupled.

[0072] Together, these three elements form a dynamically corroborating assessment matrix: "D3" and "D1" reveal the dynamic process of interaxial interaction, while the changes in "D2" verify the synergy between visual function (upper eyelid dynamic system) and facial expression function (eyebrow dynamic system). This comprehensive evaluation system provides a quantitative tool for diagnosing upper eyelid function and, from a clinical data perspective, confirms the systematic and dynamic pathophysiological essence revealed by the "triaxial model."

[0073] VI. Typical Cases

[0074] like Figure 2 , Figure 3 As shown (comparison of patient before and after surgery): Before surgery, the right eye's D2 was 17.4mm (frontalis muscle compensation for eyebrow raising), D1 was 3.5mm, and D3 was 2.4mm (superior visual field obstruction existed); After surgery, D2 was 15.2mm (difference -2.2mm, eyebrow resting position), D1 was 4.1mm (difference +0.6mm), and D3 was 6.1mm (difference +3.7mm, visual field obstruction resolved).

[0075] like Figure 4 , Figure 5 As shown in typical case 1, preoperative skin margin obstructs the field of vision:

[0076] Table 3: Changes in indicators before and after surgery in Case 1

[0077]

[0078] like Figure 4 , Figure 5 As shown in Table 3, preoperative and postoperative dynamic eye-opening videos were taken to simultaneously assess the balance of the facial muscle tension network and determine the improvement in coordination between the eyebrows, eyes, and lower face. Preoperatively, with eyes open (full face), the upper field of vision was limited, and the facial muscles were in a compensatory position, with eyebrows raised to assist in opening the eyes, resulting in a stretched lower face and a tense expression. Postoperatively, the symptoms of eyebrows raised to assist in opening the eyes were relieved (eyebrows returned to resting position), and the overall facial tension network returned to balance, resulting in a more coordinated and relaxed visual effect for the eyebrows, eyes, and lower face.

[0079] like Figure 6 , Figure 7 As shown in (typical case 2, preoperative upper eyelid margin obstructing the field of vision):

[0080] Table 4: Changes in indicators before and after surgery in Case 2

[0081]

[0082] like Figure 6 , Figure 7 As shown in Table 4, in Case 2, postoperative D1 was within the normal range of 3.5–4.5 mm on both sides, D3 was greater than D1 with no visual field obstruction, and D2 was significantly reduced. Postoperatively, the patient's eyelids were symmetrical, eyebrows and eyes were coordinated, and opening the eyes was easy and natural. The upper visual field was significantly widened, and the facial muscle tension network was restored to balance.

[0083] VII. Dynamic Video Evaluation

[0084] This invention also includes capturing pre- and post-operative dynamic eye-opening videos to simultaneously assess the balance of the facial muscle tension network and determine the improvement in coordination between the eyebrows, eyes, and lower face. For example... Figure 4 , Figure 5 As shown, before the operation, the patient's upper visual field was limited, and the facial muscles were in a compensatory position, raising the eyebrows to assist in opening the eyes, while the lower face was stretched downwards and the expression was tense; after the operation, the symptoms of raising the eyebrows to assist in opening the eyes were relieved (eyebrows returned to resting position), the overall facial tension network was restored to balance, and the appearance presented a more harmonious and relaxed visual effect of the eyebrows, eyes and lower face.

[0085] VIII. Summary

[0086] This invention constructs a complete, objective, and quantifiable evaluation system for upper eyelid function and morphology based on a three-axis functional model. By simultaneously measuring three key indicators (D2, D3, and D1) and combining them with dynamic video assessment, it can comprehensively reflect the state and linkage relationship of the support axis, dynamic axis, and contour axis, effectively eliminating interference from individual anatomical differences, and achieving accurate judgment of eyebrow compensation, visual field obstruction, levator muscle function, facial muscle tension balance, and eyebrow-eye-facial coordination. The evaluation process is standardized, repeatable, and automated, combining the advantages of static quantification and dynamic assessment, and overcoming the shortcomings of traditional evaluation methods that are one-sided, subjective, and lack systematicity. It provides a scientific and reliable new tool for upper eyelid function diagnosis, effect evaluation, and efficacy comparison.

[0087] It should be noted that the above examples are merely one specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. In short, all variations that can be directly derived or conceived by those skilled in the art from the content disclosed in this invention should be considered within the scope of protection of this invention.
