CAPILLARY NONPERFUSION AND PHOTORECEPTOR LOSS IN BRANCH RETINAL VEIN OCCLUSION: Spatial Correlation and Morphologic Characteristics.

Purpose: To evaluate the photoreceptor layer in eyes with branch retinal vein occlusion associated with macular ischemia, using a method of en face optical coherence tomography (OCT) representation of the ellipsoid zone.

Methods: Customized macular OCT scans of 9 patients (10 eyes) with branch retinal vein occlusion and macular ischemia were exported and subsequently postprocessed (removal of vascular and cystic spaces' shadows, segmentation, and alignment to the retinal pigment epithelium). The ellipsoid band was then isolated, aligned, and used to produce an en face OCT image.

Case report: Aqueous and Vitreous amino-acid concentrations in a patient with maple syrup urine disease operated on rhegmatogenous retinal detachment.

Background: Maple syrup urine disease (MSUD) is a rare metabolic disorder, affecting the metabolism of branched chain amino-acids (Valine, Leukine, Isoleukine). We present a rare case of rhegmatogenous retinal detachment (RRD) in a MSUD patient.

Case Presentation: We performed amino acid analysis of aqueous humour, vitreous and serum samples obtained during surgery from a 24 year old female MSUD patient successfully operated on RRD.

β-Thalassemia and ocular implications: a systematic review.

Background: Beta-thalassemia is a severe genetic blood disorder caused by a mutation in the gene encoding for the beta chains of hemoglobin. Individuals with beta-thalassemia major require regular lifelong Red Blood Cell transfusions to survive. Ocular involvement is quite common and may have serious implications.
