purpose: to evaluate the success rate of vitrectomy in giant retinal tears (gtr) and factors influencing it. methods: in an interventional case series, hospital records of 68 eyes of 63 patients operated for grt were reviewed. standard three port vitrectomy plus placement of an encircling band, retinopexy, and internal tamponade was performed for all eyes. possible influencing factors including...

Eales' disease is an idiopathic obliterative retinal vasculopathy that is treated with laser photocoagulation, and/or vitrectomy. In order to determine visual outcomes and regression of retinal neovascularization following scattered peripheral retinal photocoagulation, and/or vitrectomy in cases with Eales' disease, we did a retrospective study of the records of these patients treated in La...

Introduction: According to the literature, Central Retinal Arteriolar Equivalent (CRAE), Central Retinal Venular Equivalent (CRVE), and Artemio Venule Ratio (AVR) are three important markers in determining the changes of retinal artery. These markers are employed as an indicator of cardiovascular effects in workers. This study aimed to evaluate the changes in retinal micro vascular responses in...

Introduction Blue light is a part of the spectrum with the highest energy content, which can reach the retina. The damage that it can cause to the retina is called photochemical or blue-light retinal injury. For the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (W.m-2.sr-1) seems to be ...
