The recent outbreak of coronavirus disease 2019 (COVID-19) has been declared a public health emergency worldwide. scientific community put in much effort and published studies that described COVID-19’s biology, transmission, clinical diagnosis, candidate therapeutics, vaccines. However, to date, only few data are available on the impact COVID-19 pandemic ophthalmological care different systems, its future consequences terms disability, access sight-saving cures for many patients. To reduce...

Background Though several procedures of IOL implantation have been described (sutured scleral fixation, intra-scleral angle-supported anterior chamber, and chamber or retropupillary iris-claw IOLs), there are no randomized trials which comparing different techniques. Hence, the surgical treatment aphakia still remains controversial challenging. The purpose this study was to compare long-term efficacy rate complications versus posterior Iris-claw intraocular lenses (IOL) correct for without...

Abstract Purpose To analyse the postoperative foveal avascular zone (FAZ) area, superficial vessel density (SVD) and deep (DVD) their correlation with functional (best‐corrected visual acuity, BCVA) anatomical outcomes (foveal macular thickness, FMT) after surgery for rhegmatogenous retinal detachment (RRD) repair. Method Patients RRD eyes, successfully treated a single pars plana vitrectomy (PPV) gas tamponade minimum 12 months follow‐up, were re‐examined. Foveal SVD, DVD FMT evaluated by...

Trace elements might play a role in the complex multifactorial pathogenesis of age-related macular degeneration (AMD). The aim this study was to measure alterations trace levels aqueous humor patients with non-exsudative (dry) AMD. For pilot study, samples were collected from undergoing cataract surgery. 12 dry AMD (age 77.9±6.62, female 8, male 4) and 11 without 66.6±16.7, 7, included.

To investigate the neuroprotective effect of brimonidine after retinal ischemia damage on mouse eye. Glaucoma is an optic neuropathy characterized by ganglion cells (RGCs) death, irreversible peripheral and central visual field loss, high intraocular pressure. Ischemia reperfusion (I/R) injury model was used in C57BL/6J mice to mimic conditions glaucomatous neurodegeneration. Mouse eyes were treated topically with pattern electroretinogram assess function.
