O vernight, an extensive pool of subretinal fluid (SRF) disappears following the judicious application of a small plomb over a peripheral U-tear, and one can only marvel at the underlying mechanisms at play. The scleral indentation has somehow overcome the dynamic tractional forces operating in the region of the break, allowing it to close; and the ‘‘pigment epithelial pump’’ has obligingly dri...

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...

BACKGROUND Rhegmatogenous retinal detachment is one of the commonly encountered retinal problems where timely treatment could prevent irreversible vision loss. Pneumatic retinopexy (PR) is a simple and minimally invasive procedure for retinal reattachment. AIM This study aimed to assess the outcome of pneumatic retinopexy in primary rhegmatogenous retinal detachment at our facility. STUDY D...

Giant retinal tear (GRT) is defined as peripheral break extending through 900 or more of the retinal circumference in which the vitreous gel is attached essentially to the anterior flap thereby allowing independent mobility of the posterior edge of tear. GRT needs to be differentiated from Giant dialysis, which is retinal disinsertion from the ora serrata with 90 degrees or more of circumferent...

PURPOSE To report a case of rhegmatogenous retinal detachment in the late stage, despite the fact that it had previously been halted after intravitreal injection of an antimicrobial agent against endogenous bacterial endophthalmitis (EBE). CASE This study involved a 62-year-old male who had previously been diagnosed with septicemia due to liver abscess and the detection of Klebsiella pneumoni...

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 ...

Diabetic retinopathy is the major cause of blindness at working age. The pathogenesis behind visual loss is related with retinal angiogenesis and increased retinal vascular permeability. These changes seem to be the result of chronic hyperglycemia and hypoxia. Several mechanisms have been proposed to cause the retinal and vasculature cellular damage. They include the formation of advanced end g...
