Evaluation of the corneal thickness and endothelial changes following uncomplicated phacoemulsification in diabetic and non-diabetic patients with pseudo-exfoliation syndrome by specular microscopy.

Purpose: To evaluate corneal endothelial cell changes following uncomplicated phacoemulsification in diabetic patients with PEX, compared with diabetic patients and non-diabetic patients with PEX.

Methods: This prospective, comparative, non-randomized cohort study included 61 eyes of 61 patients who were diagnosed as having senile cataract. Patients were divided into three groups: Group (1) included 19 eyes of patients with DM and PEX, group (2) included 22 eyes of diabetic patients, and group (3) included 20 eyes of patients with PEX.

Macular microvascular changes in children with transfusion-dependent beta-thalassemia.

Background: To investigate the effect of iron overload on macular perfusion among transfusion-dependent thalassemia (TDT) patients using optical coherence tomography angiography (OCTA) METHODS: The study is a prospective observational case-control study. It included 27 eyes from 27 children with transfusion-dependent β-thalassemia and 25 eyes from 25 age-matched controls. All participants were evaluated clinically and with OCTA Avanti RTVue-XR system (Optovue) to assess macular microvascular changes, by measuring vessels density (VDs) and foveal avascular zone (FAZ) area, at both superficial and deep retinal plexuses and at choriocapillaris level.

Evaluation of ciliary body by ultrasound bio-microscopy after trans-scleral diode cyclo-photocoagulation in refractory glaucoma.

Purpose: To evaluate the morphological changes of the ciliary body after diode laser trans-scleral cyclo-photocoagulation using ultrasound bio-microscopy in refractory glaucoma.

Settings: This prospective, interventional, non-comparative, non-randomized, longitudinal study was performed on 40 eyes with refractory glaucoma, during the period between February 2016 and March 2018.

Methods: All patients were treated with single session diode laser trans-scleral cyclo-photocoagulation.

Accelerated Epithelium-Off Corneal Collagen Cross-Linking For Keratoconus: 12-Month Results.

Purpose: The main aim of the study was to report visual, refractive, topographic, and aberrometric results of accelerated CXL in patients with keratoconus who were followed for 12 months and to highlight the important parameters that can be used in follow-up.

Settings: It was a prospective interventional non-randomized case series study, in which 40 keratoconus eyes of 40 patients were studied in the period between April 2016 and July 2018.

Methods: All eyes were examined preoperatively and post-accelerated CXL to evaluate visual acuity, refractive state, keratometric values, keratoconus indices, and corneal higher order aberrations (HOAs).

Keratoconus Screening Among Myopic Children.

Aim: To assess the topographic corneal changes and the incidence of keratoconus among children with high myopia.

Settings: It is a prospective study, in which 174 eyes of children with high myopia were studied in the period between August 2015 and June 2018.

Methods: All patients were examined to assess the refractive error and corneal examination using Scheimpflug camera to evaluate different corneal parameters.

Effect of bilberry extract on slowing high-myopia progression in children: 2-year follow-up study.

Aim: To evaluate the effect of oral Difrarel on progression of high myopia in children and to study myopia course after its discontinuation.

Methods: A total of 64 highly myopic children were enrolled in this study. Patients were divided into two equal groups: group 1 was administered Difrarel for 1 year and stopped its intake for another year, and group 2 (control) did not take Difrarel.

Assessment of Posterior Segment Using Spectral Domain OCT in Highly Myopic Eyes.

Purpose: Spectral Domain Optical Coherence Tomography (SD-OCT) was used to evaluate retinal and vitreo-retinal changes that occur in highly myopic patients.

Methods: This prospective study included 472 eyes of 472 patients suffering from high myopia (> -6.00 D), between May 2012 and December 2015.

Evaluation of Optic Nerve Head Parameters and Retinal Nerve Fiber Layer Thickness in Axial Myopia Using SD OCT.

Introduction: The purpose of this research was to study the effect of increased axial myopia, in non-glaucomatous eyes, and its correlation with ONH parameters, and RNFL thickness, using Cirrus HD 4000 SD-OCT.

Methods: The myopia group included 86 eyes of 86 patients, while the control group involved 92 eyes of 92 patients, attending the Ophthalmology Outpatient Clinic in Minia University Hospital, between November 2013 and March 2015. ONH parameters and peripapillary RNFL thickness measurement were evaluated by using SD-OCT, selecting the standard optic disc cube 200 × 200.
