PURPOSE The aim of the present study was to compare macular thickness in patients with keratoconus (KC) with macular thickness in healthy subjects. SUBJECTS AND METHODS Twenty-six patients with KC and 52 control subjects were included. The macular structure was evaluated using a Zeiss Cirrus HD-OCT. The scan pattern used was 512 × 128, which covers an area of approximately 6 × 6 mm of the ret...

PURPOSE To evaluate macular retinal ganglion cell-inner plexiform layer (GCIPL) thickness changes after Brilliant Blue G-assisted internal limiting membrane peeling for idiopathic macular hole repair using a high-resolution spectral-domain optical coherence tomography (SD-OCT). METHODS 32 eyes from 32 patients with idiopathic macular holes who underwent vitrectomy with internal limiting membr...

Purpose. To investigate the correlation between aqueous and serum levels of pigment epithelium-derived factor (PEDF) and macular choroidal thickness in high myopia patients, both with and without choroidal neovascularization (CNV). Methods. Serum and aqueous levels of PEDF were measured by enzyme-linked immunosorbent assay in 36 high myopia patients (36 eyes) with no CNV (non-CNV group), 14 hig...

Full thickness macular holes have an estimated prevalence of 1/3300, with more than fifty percent occurring in patients aged 65-74 years [1]. The vast majority (>80%) are idiopathic, with smaller proportions occurring in the setting of trauma, inflammation, and myopia. Furthermore, it is estimated that even fewer (less than 1% of full thickness macular holes (FTMH)) have been reported in associ...

The purpose of this study was to compare the optic disc parameters, retinal nerve fiber (RNFL), and macular ganglion cell layers between patients with diabetes mellitus (DM) type 2 and healthy controls.In this cross-sectional study, 69 eyes of 69 diabetic patients without diabetic retinopathy and 47 eyes of 47 healthy controls were included. Optic disc parameters (i.e., rim area, disc area, cup...

Between 1975 and 1989, 11 eyes were treated for retinal detachments with both peripheral and full thickness macular breaks. Long term retinal reattachment was dependent on successful closure of peripheral retinal breaks. Direct treatment of the macular break was necessary in only one case, which redetached 3 months after vitrectomy. Vitrectomy is not the initial treatment of choice for uncompli...

PURPOSE To compare the macular retinal thickness and characteristics of optic nerve head (ONH) parameters in amblyopic and fellow eyes in patients with unilateral amblyopia. PATIENTS AND METHODS A total of 21 patients with unilateral amblyopia (14 patients with anisometropic amblyopia, four patients with strabismic amblyopia, and three patients with both) were examined using spectral-domain o...

PURPOSE To assess the correlation and agreement between the Topcon built-in algorithm and our graph-based algorithm in measuring the total and regional macular thickness for normal and glaucoma subjects. METHODS A total of 228 normal eyes and 93 glaucomatous eyes were enrolled in our study. All patients underwent comprehensive ophthalmic examination and Topcon 3D-OCT 2000 scan. One eye was ra...

PURPOSE To report a case of radiation-induced macular ischemia where vision and macular perfusion improved after hyperbaric oxygen (HBO) therapy. METHODS A 62-year-old male patient developed radiation-induced macular ischemia after he was treated with radiation for brain glioma. The patient presented with best spectacle-corrected visual acuity (BSCVA) acuity of 20/400 in his right eye. Optica...

An impending macular hole, also known as a stage 1 macular hole, is considered the precur‐ sor to a full thickness idiopathic macular hole. Impending macular holes have a splitting of the inner retina with the clinical appearance of a foveolar cyst or pseudocyst. In some cases, this inner splitting can be associated with a defect in the underlying outer retina (Lee, Kang et al. 2011). An impend...
