Corneal Deposits: A Presentation of Arthrobacter Keratitis.

Introduction: Infectious keratitis, an inflammatory condition of the cornea, poses a significant public health concern globally. Bacterial keratitis, the most common type, primarily involves and . Timely diagnosis and treatment are crucial to prevent vision loss.

Whole-exome screening for primary congenital glaucoma in Lebanon.

Purpose: Mutations were previously identified in the CYP1B1 gene in six out of 18 Lebanese families (33%) with primary congenital glaucoma (PCG). The purpose of this study is to determine the frequency and type of pathogenic mutations in other genes and compare to other populations using whole-exome sequencing and perform genotype-phenotype correlations.

Methods: Twelve PCG patients previously negative for CYP1B1/MYOC mutations were subjected to whole-exome sequencing.

Bevacizumab and neovascular age related macular degeneration: pathogenesis and treatment.

The pathogenesis of neovascular age related macular degeneration (AMD) is multifactorial including inflammation and angiogenesis leading to choroidal neovascularization (CNV). Therapy against vascular endothelial growth factor (VEGF) has revolutionized the treatment of neovascular AMD. Intravitreal off-label use of bevacizumab proved to be safe.

Molecular basis of oculocutaneous albinism type 1 in Lebanese patients.

Oculocutaneous albinism type 1 (OCA1) results from mutations in the tyrosinase gene, which lead to partial or complete loss of activity of the corresponding enzyme. A large number of mutations have been identified worldwide, providing insight into the pathogenesis of the disorder. We performed ophthalmic and dermatological exams on 30 Lebanese subjects with oculocutaneous albinism, then screened for mutations in the tyrosinase gene in an effort to establish the molecular basis of the disorder in our population and correlate it with phenotypic findings.
