Effect of Light Conditions and Accommodation on Implantable Phakic Contact Lens Vault by Anterior Segment Optical Coherence Tomography.

Purpose: To investigate the dynamic pupil and vault changes in eyes with implantable phakic contact lens (IPCL) under photopic and scotopic settings, as well as during accommodation using the anterior segment optical coherence tomography (AS-OCT).

Methods: A prospective observational study included consecutive 36 eyes of myopic patients who underwent IPCL V2.0 implantation.

Macular vessel density before and after panretinal photocoagulation in patients with proliferative diabetic retinopathy.

Introduction: Diabetic retinopathy (DR) is microangiopathy causing ischemia leading to proliferative diabetic retinopathy and macular edema. Panretinal photocoagulation (PRP) reverses the ischemia leading to regression of neovessels. Most previous studies showed the large vessel effects of PRP, while optical coherence tomography angiography (OCTA) allowed noninvasive quantification of microvascular retinal changes.

Early and delayed suture adjustments after adjustable suture strabismus surgery: a randomized controlled trial.

Background: Adjustable sutures increase the success rate of strabismus surgery. However, the optimal timing of postoperative suture adjustment remains controversial. This trial was aimed at comparing the surgical outcomes and pain scores of early or 2 - 4 h and delayed or 24 h postoperative suture adjustment in adult patients undergoing strabismus surgery.

Corrected Intraocular Pressure Variability with Central Corneal Thickness Measurement.

Purpose: To evaluate variability in measured intraocular pressure (IOP) values when correlated with central corneal thickness measurements obtained by both ultrasonic and optical tools.

Patients And Methods: We included 46 eyes of 46 healthy subjects (age range 35-76 years). Exclusion criteria for the current study were patients with confirmed diagnosis of glaucoma, glaucoma suspect patients and those having corneal opacities, scars or prior cornea-based laser vision correction.

Clinical Profile of -Associated Uveitis in an Egyptian Cohort.

Purpose: To describe the clinical profile of patients with HLA-B27-associated uveitis at 2 Egyptian tertiary eye centers.

Methods: A retrospective study reviewing the medical records of all patients with HLA-B27-associated uveitis served at 2 uveitis referral clinics in Egypt between January 2010 and June 2018.

Results: The study included a total of 554 patients.

Evaluation of primary internal limiting membrane peeling in cases with rhegmatogenous retinal detachment.

Background: Epiretinal membranes (ERMs) have been reported after pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). Peeling of the internal limiting membrane (ILM) can prevent post-PPV ERM formation but has a potential negative impact on macular structure and function.

Purpose: To investigate the anatomical and functional outcomes of ILM peeling during PPV for primary RRD.

Differential time-course tear film quantitative changes following limbal relaxing incisions.

Background: The study aims at evaluating the time-course changes of pre-corneal tear film after simultaneous phacoemulsification and limbal relaxing incisions (LRIs) performed in 2 groups of patients; group-A had vertical and group-B had horizontal LRIs.

Methods: Fourty-two eyes of 28 patients with co-existing cataract and corneal astigmatism were studied before and after simultaneous cataract surgery and LRIs (at weeks 1, 4 and 12), patients were classified into 2 groups according to the orientation of LRIs; vertical (A) and horizontal (B) groups. Pre-corneal tear film stability was assessed by measuring the tear break-up time (TBUT) and the tear volume was determined using Schirmer's I test (Basic Schirmer's test; BST), both preoperatively and postoperatively.

Comparison Between Silicone Oil and Gas in Tamponading Giant Retinal Breaks.

Purpose: The purpose of this study is to compare anatomical and visual outcomes after using silicone oil (SO) or CF gas as tamponades after pars plana vitrectomy (PPV) for retinal detachment (RD) associated with giant retinal tears (GRTs).

Methods: A retrospective chart review was conducted for cases that underwent PPV for GRT-associated RD. We excluded eyes that had prior vitreoretinal surgery, a history of ocular trauma or worse than grade B proliferative vitreoretinopathy (PVR).

Pattern of Intermediate Uveitis in an Egyptian Cohort.

: To describe the clinical experience with intermediate uveitis at six Egyptian tertiary eye centers.: A multicenter retrospective chart review of all patients with intermediate uveitis seen at six ocular inflammation referral clinics in Egypt between January 2010 and January 2017.: The study included a total of 781 patients with intermediate uveitis.

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.
