purpose: to evaluate the outcomes of vitrectomy for complications of branch retinal vein occlusion (brvo). methods: this retrospective study, included patients who underwent vitrectomy surgery due to the complications of brvo over an 11-year period. visual acuity and retinal condition were evaluated before and after surgery. results: the study included 30 eyes of 30 patients with mean age of 64...

Introduction: The present study aimed to present a numerical analysis of the penetration depth,  specific absorption rate (SAR), and temperature rise in various eye tissues with varying distance between radiation source and exposed human eye tissues (i.e., cornea, posterior chamber, anterior chamber, lens, sclera, vitreous humor, and iris) at frequencies of 900 and1800 MHz. Materials and Method...

We report a case of a patient with a highly hyperopic eye who underwent cataract surgery combined with vitreous surgery to create a posterior vitreous detachment (PVD) to prevent choroidal neovascularization (CNV). A 78-year-old man noticed a decrease in his vision due to a cataract in his right eye. The patient had a severe visual loss in his left eye because of a CNV 2 years after a cataract ...

PURPOSE Vitrectomy is associated with the rapid progression of nuclear cataracts. This study was conducted to test the hypothesis that age-related liquefaction of the vitreous gel may also be associated with lens opacification. METHODS Lenses from eye bank eyes were graded for nuclear, cortical, and posterior subcapsular opacities, and the amount of liquid vitreous was measured. RESULTS Nuc...

Vitreomacular traction (VMT) syndrome and macular hole (MH) are disease processes that are caused by anomalous separation of the vitreous from the macula. Until now, management of these conditions has involved vitreoretinal surgery. Clinical trials have shown that a single intravitreal microplasmin (ocriplasmin) injection can induce separation of the vitreous from the macular surface and thereb...

CLINICAL CASE Man carrier of the von Hippel-Lindau (VHL) gene, with long-onset loss of vision in left eye. He had a retinal capillary hemangioma (HCR) and diffuse cystic edema in posterior pole. The systemic study revealed bilateral kidney tumors. Laser photocoagulation was performed which produced a subretinal and vitreous hemorrhage that required vitrectomy. DISCUSSION Retinal capillary hem...

PURPOSE It is aimed to report on a 16-year-old patient with acquired ocular toxoplasmosis complicated by a retinal tear. METHODS Retrospective medical chart review. RESULTS A 16-year-old Caucasian female presented with vision loss in her right eye. In addition to a white active lesion between the fovea and the optic nerve head, marked vitreous opacification was noted. She was diagnosed with...

PURPOSE To investigate the rate of lens subluxation following plasmin and/or SF6 injections in eyes, and whether a subsequent elevated level of vascular endothelial growth factor (VEGF) and vitreous tap would aggravate subluxation. METHODS Four groups of rabbits were used. Group 1 received an intravitreal injection (IVI) of plasmin and SF6 in the right eye; group 2 received an IVI of plasmin ...

The measurement process in fluorophotometry inherently involves a loss of information due to the finite sampling volume of the instrument. Mathematically, the effect is expressed as a convolution of the actual fluorescein distribution with the spread function of the instrument. Scattering by the ocular media can increase the spread function over that due to the instrument alone. A method is pro...
