Purpose: To determine whether patients with sporadic, non-familial keratoconus and no pathogenic mutations in the visual system homeobox 1 (VSX1) gene have evidence of chromosomal copy number alterations.

Purpose: To screen the visual system homebox 1 (VSX1) gene in Saudi Arabian keratoconus patients.
Methods: We sequenced the entire coding region, exon-intron boundaries in clinically confirmed keratoconus patients (n=55) and 50 ethnically matched healthy controls. All cases and controls were unrelated.

We report a case of Vogt–Koyanagi– Harada (VKH) disease in a 30-year-old patient who was receiving interferon-alpha and ribavirin therapy for chronic hepatitis C virus infection. The intraocular inflammation responded to systemic corticosteroid and mycophenolate mofetil treatment. Physicians should be aware of the association between interferon-alpha and ribavirin therapy for hepatitis C virus infection and the development of VKH disease.

Purpose: To evaluate the clinical efficacy and safety of controlled contact transscleral diode laser Cyclophotocoagulation (COCO) procedure in reducing the Intraocular Pressure (IOP) among patients with refractory glaucoma.
