Standardization of meibomian gland dysfunction in an Egyptian population sample using a non-contact meibography technique.

Aim: To develop normative data for meibomian gland dysfunction (MGD) parameters, using non-contact meibography technique of Sirius Costruzione Strumenti Oftalmici (CSO) machine, in an Egyptian population sample.

Methods: Observational, cross-sectional, analytic study, in which 104 Egyptian volunteers were included. Both upper lids were examined, using " CSO" machine.

Evaluation of the retinal and choroidal microvasculature changes in cases of sarcoid and tuberculosis-associated posterior uveitis using OCT angiography.

Purpose: Using optical coherence tomography angiography (OCTA) to evaluate retinal microvascular changes in sarcoid and tuberculous (TB) posterior uveitis.

Methods: Cross-sectional observational study includes 30 eyes. FFA and OCTA images were acquired.

Transscleral sutureless intraocular lens versus retropupillary iris-claw lens fixation for paediatric aphakia without capsular support: a randomized study.

Purpose: To compare results of sutureless transscleral intraocular lens (IOL) fixation to retropupillary iris-claw lens implantation in cases of paediatric aphakia without capsular support.

Methods: Thirty eyes of children with insufficient capsular support for IOL implantation were randomized to undergo sutureless transscleral IOL fixation or iris-claw lens fixation. The primary outcome was best-corrected visual acuity (BCVA).

Factors influencing the outcome of goniotomy and trabeculotomy in primary congenital glaucoma.

Purpose: To study the prognostic factors influencing intraocular pressure (IOP) reduction and success rates of paediatric goniotomy and trabeculotomy.

Patients: Data from patients aged ≤12 years who underwent goniotomy or trabeculotomy for primary congenital glaucoma from 2013 to 2016 were reviewed. The analysis included 452 eyes of which 120 eyes of patients with a median age (IQR) of 6 months (4.

Constitutional retinoblastoma gene deletion in Egyptian patients.

Background: Retinoblastoma is a neuroblastic tumor of childhood with an incidence of 1: 20 000. Retinoblastoma gene (Rb1) is a tumor suppressor gene that is located on the long arm of chromosome 13 at region 14. This study was to evaluate the constitutional monoallelic Rb1 deletion among retinoblastoma families.
