Demographics and etiologic characteristics of non-glaucomatous optic atrophy: a single-center cross-sectional study from Turkey.

Background: Optic atrophy is an end-stage pathology of optic nerve diseases that is characterized by optic nerve pallor and vision loss. Because of its sight-threatening effects, understanding its epidemiology and etiology is crucial. In this study, we aimed to determine the epidemiologic features of optic nerve pathologies which lead to optic atrophy.

Retinal Optical Coherence Tomography in Neuromyelitis Optica.

Background And Objectives: To determine optic nerve and retinal damage in aquaporin-4 antibody (AQP4-IgG)-seropositive neuromyelitis optica spectrum disorders (NMOSD) in a large international cohort after previous studies have been limited by small and heterogeneous cohorts.

Methods: The cross-sectional Collaborative Retrospective Study on retinal optical coherence tomography (OCT) in neuromyelitis optica collected retrospective data from 22 centers. Of 653 screened participants, we included 283 AQP4-IgG-seropositive patients with NMOSD and 72 healthy controls (HCs).

Cohort profile: a collaborative multicentre study of retinal optical coherence tomography in 539 patients with neuromyelitis optica spectrum disorders (CROCTINO).

Purpose: Optical coherence tomography (OCT) captures retinal damage in neuromyelitis optica spectrum disorders (NMOSD). Previous studies investigating OCT in NMOSD have been limited by the rareness and heterogeneity of the disease. The goal of this study was to establish an image repository platform, which will facilitate neuroimaging studies in NMOSD.

Effect of Hemifacial Spasm on Intraocular Pressure Measurement.

Purpose: To evaluate the effect of hemifacial spasm (HFS) on intraocular pressure (IOP) measurement.

Methods: Twenty-four consecutive patients with HFS and 25 age- and gender-matched randomly selected eyes of healthy volunteers underwent corneal pachymetry and IOP measurements using Goldmann applanation tonometer (GAT) and noncontact tonometer (NCT). IOP measurements were performed before (during HFS) and 2 weeks after Botox injections in HFS patients and in healthy volunteers without Botox injections.

Corneal Biomechanical Properties in Obstructive Sleep Apnea Syndrome.

Objectives: To investigate the corneal biomechanical properties and anterior segment parameters in patients with obstructive sleep apnea syndrome (OSAS).

Methods: Fifty-four eyes of 54 patients with OSAS and 20 eyes of 20 healthy subjects were included. Patients with mild and moderate OSAS (Respiratory Disturbance Index [RDI] <30) enrolled in group 1, those with severe OSAS (RDI≥30) in group 2 and controls in group 3.

Eye Injuries from Pencil Lead: Three Cases.

Corneal stromal and/or penetrating ocular injuries from pencils and pencil lead are more common in childhood and may lead to intraocular infection or severe intraocular sterile inflammatory reaction. Herein we report 3 children with ocular trauma due to pencil lead injuries. The first case had corneal stromal injury caused by a pencil.

Corneal Viscoelastic Properties in Patients with Angioid Streaks.

Purpose: The aim of this study is to investigate the possible corneal biomechanical changes in patients with angioid streaks and to understand if the calcified and thickened Bruch's membrane associated with angioid streaks influences elasticity of the eye and intraocular pressure.

Materials And Methods: Twelve eyes of 12 patients with angioid streaks (six males and six females) and 12 eyes of 12 age- and sex-matched healthy volunteers were enrolled in the study. Corneal hysteresis (CH), corneal resistance factor (CRF), corneal compensated intraocular pressure (IOPcc) and Goldmann-correlated intraocular pressure (IOPg) were measured with an Ocular Response Analyzer (ORA).

Comparison of retinal nerve fiber layer and macular thickness measurements with Stratus OCT and OPKO/OTI OCT devices in healthy subjects.

Aim: To compare retinal nerve fiber layer (RNFL) and macular thickness measurements obtained with the Stratus optical coherence tomography (OCT) and OPKO/OTI OCT devices.

Methods: Included in the study were 59 eyes of 30 participants. All measurements for each eye were done on the same day with both devices.

Exodeviation following monocular myopic regression after laser in situ keratomileusis.

We report a 44-year-old woman with intermittent left exotropia of 35 prism diopters at distance who initially exhibited alignment of both eyes after bilateral laser in situ keratomileusis (LASIK). The exophoria was not preserved due to myopic regression in the dominant eye. An uneventful LASIK treatment was performed to correct -11.

Repair of Descemet's membrane detachment after viscocanalostomy.

We report an alternative descemetopexy technique in a case of Descemet's membrane detachment after viscocanalostomy, possibly caused by high-molecular-weight viscoelastic material.
