Abstract
Systems and methods for ophthalmic disease detection and risk assessment that combines digitally-augmented examination instruments with neural networks trained to analyze examination imagery across diverse patient populations and variable image qualities, enabling automated analysis and classification of eye conditions during routine clinical examinations.
Claims9
A system for automated ophthalmic diagnostic classification using video ophthalmoscopy, comprising:
- an imaging device configured to acquire video frames and/or static images of a subject's optic disc during an ophthalmoscopic examination;
- an input module for receiving said video frames and/or static images;
- a neural network operatively connected to the input module, the neural network configured to:
- analyze the acquired video frames and/or static images using a machine learning model trained to segment optic nerve head features across varying image qualities and patient populations;
- measure a radial width of a neuroretinal rim by determining a shortest distance between an outer optic disc margin and an inner cup margin from the segmented optic nerve head features, wherein the measurement:
- substantially or completely excludes blood vessels extending beyond rim tissue;
- accounts for a circumferential extent of complete rim absence, if present;
- and
- is taken along a radial line extending from a center of the optic disc to a location where the rim is thinnest;
- calculate a Disc Damage Likelihood Scale (DDLS) score based on the measured neuroretinal rim width and an optic disc size;
- adjust the calculated DDLS score based on the optic disc size;
- and
- an output module configured to:
- provide real-time or substantially real-time DDLS classification during the ophthalmoscopic examination;
- generate a report indicating glaucoma risk assessment based on the DDLS score;
- and
- suggest clinical recommendations based on the risk assessment.
