Inter-observer agreement in grading severity of diabetic retinopathy in wide-field fundus photographs.

Objective: To examine the inter-observer agreement between two retina specialists in grading diabetic retinopathy (DR) severity in ultra-wide-field fundus photographs.

Methods: Two hundred and seventy patients with diabetes, who visited the vitreoretinal specialty at a tertiary eye care hospital, with or without DR underwent comprehensive ophthalmic examination, dilated retinal exam and Optos ultra-wide-field (UWF) retinal photography. Optos images were graded for DR severity based on the International Clinical Diabetic Retinopathy Disease Severity Scale by two retina specialists with same number of years of experience, masked to the clinical details of the participants.

OCT angiography features of paracentral acute middle maculopathy.

Paracentral acute middle maculopathy (PAMM) refers to retinal lesions with changes in the inner nuclear layer on spectral domain optical coherence tomography (OCT). PAMM is associated with retinal vascular pathology involving the deep capillary plexus. We report two cases of PAMM in Indian subjects using multimodal imaging highlighting the OCT angiography (OCTA) findings.
