The bis-retinoid pigments that accumulate in retinal pigment epithelial cells as lipofuscin are associated with inherited and age-related retinal disease. In addition to A2E and related cis isomers, we previously showed that condensation of two molecules of all-trans-retinal leads to the formation of a protonated Schiff base conjugate, all-trans-retinal dimer-phosphatidylethanolamine. Here we r...

Newly Recognized Serous Macular Detachment in Retinal Vascular Disease Serous macular detachment has only recently been recognized to occur in a significant number of eyes with retinal vascular leakage, including diabetic macular edema,1,2 branch retinal vein occlusion,3–5 central retinal vein occlusion (CRVO),6 and hypotony maculopathy.7 These serous retinal detachments associated with retinal...

Purpose To demonstrate the utility of a novel in vivo molecular imaging probe, HYPOX-4, to detect and image retinal hypoxia in real time, in a mouse model of retinal vein occlusion (RVO). Methods Retinal vein occlusion was achieved in adult mice by photodynamic retinal vein thrombosis (PRVT). One or two major retinal vein(s) was/were occluded in close proximity to the optic nerve head (ONH). ...

BACKGROUND/AIMS A moderately elevated plasma concentration of the sulphur amino acid homocysteine is an independent risk factor for atherosclerotic vascular disease. Many of the risk factors associated with coronary, cerebral, and peripheral atherosclerotic vascular disease are common to retinal vascular occlusive disease but it is unclear whether elevated plasma concentrations of homocysteine ...

purpose : vitreoretinal surgery can be difficult or impossible in patients with corneal opacity. one solution for this problem is use of temporary keratoprosthesis (tkp). we report anatomical and visual outcomes of this combined surgery in our institution. methods : we retrospectively reviewed charts of patients in whom a tkp was used between 2006 and 2010 with follow-up of at least six months....

Highlights•Effect of JPEG compression on morphometric vascular measurements were reported.•Retinal computed with VAMPIRE software.•Agreement between from compressed and uncompressed images studied.

The surface properties of mixed monomolecular films of retinal and phospholipids were studied at a nitrogen/water interface. The subphase was glycine buffer pH 10.5 with an ionic strength of 0.1. Monomolecular films of retinal in the presence of amino acids were also measured. The area per molecule, at a surface pressure of 10 dyn/cm, A10, in the dark for 9-cis retinal and 11-ci‘s retinal are 4...

PURPOSE The present study aimed to describe clinical characteristics of patients with posterior vitreous detachment (PVD), to determine the prevalence of retinal tears in PVD patients, and to find predictors for retinal tears in this patient group. METHODS Retrospective analysis of medical records on patients diagnosed with PVD, retinal tears, or vitreous hemorrhage at the Department of Ophth...

Retinal vein occlusions (RVO) are the second commonest sight threatening vascular disorder. Branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO) are the two basic types of vein occlusion. Branch retinal vein occlusion is three times more common than central retinal vein occlusion and- second only to diabetic retinopathy as the most common retinal vascular cause of visu...
