Impact of panretinal photocoagulation on optic nerve head parameters.

Background: To investigate the impact of panretinal photocoagulation (PRP) on quantitative optic nerve head (ONH) assessment in patients with diabetic retinopathy.

Methods: Eighty eyes of 80 diabetic patients who did not undergo PRP and 45 eyes of 45 subjects with diabetes who underwent PRP were enrolled in the prospective, cross-sectional study. Participants were evaluated by confocal scanning laser ophthalmoscopy (CSLO).

Is there a correlation between diabetes mellitus and central corneal thickness?

Purpose: To evaluate the association of central corneal thickness (CCT) with diabetes mellitus and compare it with age and sex-matched healthy controls.

Materials And Methods: This study included 245 eyes of 245 subjects (one eye per subject). One hundred diabetic patients constituted the study group and 145 were healthy controls.

Traumatic optic nerve avulsion.

A 10-year-old boy presented with optic nerve avulsion associated with ptosis and limitation of elevation and adduction secondary to blunt ocular trauma. At the initial examination the funduscopic view was hazy because of concurrent vitreous hemorrhage. Ultrasonography revealed a posterior ocular wall defect and a hypolucent area in the region of the optic nerve head.

Lepromatous iridocyclitis.

A 36-year-old woman with no prior medical history presented with a unilateral decrease in vision and iridocyclitis to our hospital. External examination demonstrated multifocal, firm, elevated, non-tender skin nodules on the patient's face and left hand. In addition, slit-lamp biomicroscopy revealed gray, cheesy-appearing nodules on the iris surface of the affected eye.

Optic atrophy and macular degeneration as initial presentations of subacute sclerosing panencephalitis.

Purpose: To report a case of subacute sclerosing panencephalitis in which the initial clinical presentations were optic atrophy and macular degeneration.

Design: Observational case report.

Methods: A 9-year-old boy with visual loss attributable to optic atrophy and macular degeneration had a diagnostic examination.

Subclinical optic neuropathy in Graves' orbitopathy.

Purpose: The aims of the study were to detect early changes in the optic nerve function of patients with Graves' orbitopathy (GrO) who do not have any signs and symptoms of optic neuropathy, using pattern visual evoked potentials (P-VEP), and investigate any possible relation between the disease activity and P-VEP P100 latencies of the patient group.

Methods: The study was conducted in a tertiary care hospital. Sixteen patients with GrO and 15 healthy controls were enrolled.
