To investigate the prevalence of posttraumatic stress disorder (PTSD) in patients who underwent surgery for primary rhegmatogenous retinal detachment and to explore variables associated with the disorder. ⋯ Posttraumatic stress disorder may develop in the aftermath of primary rhegmatogenous retinal detachment. Previous traumatic events and NEI-VFQ-25 scores were found as independent risk factors for PTSD prediction.

To determine the prevalence of retinal vein occlusions (RVOs) in rural central India. ⋯ In the rural agrarian low-income population of Central India, RVOs were detected in 0.8% of adults, with branch retinal vein occlusions being approximately seven times more common than central retinal vein occlusions. Main associated factors were higher age, blood pressure, urea blood concentration, and narrow chamber angle. RVOs were no major reason for visual impairment.

We assess for frequency and predictive factors related to sustained intraocular pressure (IOP) elevation in eyes with neovascular age-related macular degeneration receiving intravitreal injections of ranibizumab and/or bevacizumab. ⋯ A greater number of intravitreal anti-vascular endothelial growth factor injections is associated with an increased risk for sustained IOP elevation in eyes with neovascular age-related macular degeneration receiving intravitreal ranbizumab and/or bevacizumab.

To analyze the viscoelastic properties of the chopped vitreous at different cut rates to better understand complex fluidic behavior of chopped vitreous during vitrectomy. ⋯ Cut rate affects the rheologic properties of the chopped vitreous and, therefore, its flow inside the vitrectomy system. It is essential to account for both viscosity and elasticity of chopped vitreous to understand flow behavior during vitrectomy.
