Other ophthalmic lesions in the fundus
When screening the diabetic population for diabetic retinopathy (DR), many other retinal conditions can be identified, which may represent harmless variations of normality or serious ophthalmic pathology. The most important conditions that may be detected are retinal vein and artery occlusion, hypertensive retinopathy, arterial emboli, and retinal changes due to blood disorders, for example, anaemia. These conditions need local protocols for management, which are best obtained by input and advice from the relevant medical teams. Overall, familiarity with fundal appearance and pattern recognition are important in order to recognize common abnormalities, for example, drusen, chorioretinitis, asteroides hyalosis, choroidal naevi, and age-related macular degeneration.
