Review of Optical Coherence Tomography Image Analysis for Retinal Disorders

Though glaucoma is the second leading cause of blindness all around the world, it is also caused due to various disorders like Cystoid macular edema (CME), and Symptomatic exudates-associated derangements (SEAD). These are caused due to excessive accumulation of fluids within the retinal layers. Hence automations in diagnosis of fluid volume plays a key role I the treatment of such disorders. Optical Coherence Tomography (OCT) measures the optical reflections of the internal structures of the biological tissues. It also serves a major tool in diagnosing several blinding diseases including Age related macular degeneration (AMD), retinopathy, glaucoma, and Cystoid Macular Edema (CME). This paper reviews various methodologies proposed so far in terms of their sensitivity, specificity, precision, accuracy and shortcomings. It also proposes some techniques to overcome the shortcomings of these methodologies.
