Embodiment 1

[0039] An application of IFA combined with FFA in DR merging DI, comprising the following steps:

[0040] (1) Use tropicamide eye drops to dilate the pupils for 30 minutes before the examination;

[0041] (2) Conduct allergy tests on patients with sodium fluorescein;

[0042] (3) For patients without allergies, perform IFA examination first: turn the focusing knob on the back of the Heidelberg confocal laser scanning fundus angiography (Spectralis HRA) to the right to focus the camera objective lens on the iris, and click FA on the touch screen. mode, and then inject contrast agent; when 5 ml of contrast agent is injected into the cubital vein, click the Inj mode on the touch screen to synchronize the timing, observe the iris blood vessel or neovascular fluorescence leakage of one eye 13-25s after contrast agent injection, Quickly move the objective lens of the HRA camera to the fellow eye for 50 seconds to observe the fluorescence leakage of iris blood vessels or new blood v...

Abstract

The invention discloses an application of combined IFA and FFA to merged DR and DI. The application method includes the following steps that 1, eye mydriasis is dropped for 30 minutes with tropicamide eye drops; 2, patients are subjected to a sodium fluorescein allergy test; 3, patients free of allergy phenomenon are subjected to IFA inspection; 4, then the patients are subjected to FFA inspection; 5, IFA inspection is repeated; 6, FFA inspection is repeated. Combined IFA and FFA inspection is compared with a past separated IFA inspection and FFA, merged-DR-and-DI patients can be comprehensively evaluated through combined-IFA-and-FFA inspection in one time of inspection, and the one-time-IFA-inspection cost is saved for all the patients. More importantly, early-merged-DR-and-DI patients can be discovered through combined-IFA-and-FFA inspection, the basis is provided for individualized treatment accordingly, and it is prevented that the illness state is evolved to blind neovascular glaucoma from NPDI or PDI.

Description

technical field [0001] The invention belongs to the technical field of ophthalmic diseases, and in particular relates to a method for treating diabetic retinopathy combined with diabetic iris disease, that is, the application of IFA combined with FFA in DR combined with DI. Background technique [0002] Currently, diabetic iridopathy (DI) examination mainly includes slit lamp examination and iris fluorescein angiography (IFA) examination. Slit lamp examination can only detect new blood vessels on the surface of the iris, but cannot find new blood vessels hidden by the brown iris. Although IFA examination is the gold standard for diagnosing DI, it can only indirectly evaluate the condition of diabetic retinopathy (DR) and cannot guide the treatment of DR. Clinically, 35%-83% of DR patients do not have DI, and IFA alone is not suitable for such DR patients. [0003] The diagnosis of DR is mainly based on fundus fluorescein angiography (FFA) examination. FFA examination can ...
