Problems solved by technology

Applying sufficient illumination to the patient's drug-free eye for high-definition imaging will generally cause rapid pupillary response, i.e., significantly reducing the area through which internal ocular features can be viewed and thus limiting the available field of view

Embodiment Construction

[0022] Embodiments disclosed herein include methods, apparatus, and computer-readable media containing instructions for performing methods of imaging ocular features. As used herein, an ocular feature is defined as any anatomical structure, part, surface or region of the eye. For example, representative ocular features include, but are not limited to, the retina, optic nerve, retinal vasculature, and similar structures. The methods and apparatus disclosed herein can be used to obtain images of animal eyes or human eyes. The images obtained may be used for any suitable purpose including, but not limited to, diagnosis of abnormalities, conditions, diseases or healthy ocular features and monitoring of these conditions over time.

[0023] The methods and devices disclosed herein are particularly useful for obtaining one or more high-quality images of ocular features in situations where the patient is unable to keep their eyes absolutely still. For example, animals, infants, and ...

Abstract

A method, apparatus and software containing instructions for obtaining an image of an ocular feature are disclosed. The disclosed embodiments include at least the steps of defining one or more selection criteria which are related to an ocular feature of interest. The selection criteria may relate to an ocular feature type, an ocular feature location, or other relevant matters. The method further includes capturing a stream of sequential ocular images and autonomously scoring some or all ocular images according to the selection criteria. Images that score above a defined score threshold may be selected as individual images more likely to include a suitable representation of the ocular feature of interest than other individual ocular images.

Description

technical field [0001] Embodiments disclosed herein relate to methods and apparatus for obtaining images of eye features, and in particular, to methods and apparatus for capturing suitable eye feature images in situations where a subject's eyes may be moving or not artificially enlarged. Background technique [0002] It is often desirable to capture digital images of ocular features for many medical or veterinary purposes. As used herein, an ocular feature is defined as any anatomical structure associated with an animal or human eye. For example, ocular features may include, but are not limited to, the retina, optic nerve, or retinal vascularization of the eye of an animal or human subject. Digital images of ocular features can be used to aid in the diagnosis of conditions, abnormalities, diseases, or healthy eyes. Similarly, a series of images of ocular features taken over time can be used to track the progression of a condition, abnormality, disease, or healthy eye. [...
