To determine the size of the foveal avascular zone (FAZ) before and after vitrectomy for a macular hole (MH). Retrospective case series study. Twenty-five eyes of 25 patients with a unilateral MH that had undergone vitrectomy with internal limiting membrane peeling were studied. The unaffected 17 fellow eyes were studied in the same way. En face images of(More)
To clarify the correlation between temporal circumpapillary retinal nerve fiber layer (RNFL) thickness and macular ganglion cell complex (mGCC) thickness in glaucomatous eyes. Seventy-seven eyes of 77 subjects were categorized as normal, early glaucoma and moderate-to-advanced (moderate) glaucoma. After the circumpapillary RNFL thickness and mGCC thickness(More)
BACKGROUND To assess the relationship between macular ganglion cell complex and macular outer retinal thicknesses. DESIGN Case-control study. PARTICIPANTS Forty-two normal eyes and 91 eyes with primary open-angle glaucoma were studied. METHODS Spectral-domain optical coherence tomography (RTVue-100) was used to measure the macular ganglion cell(More)
BACKGROUND We examined the influence of high myopia on conventional spectral-domain optical coherence tomographic parameters and assessed the macular ganglion cell complex thickness to macular outer retinal thickness ratio as a new optical coherence tomography parameter. DESIGN Prospective cross-sectional study. PARTICIPANTS Sixty normal and 30 highly(More)
To compare macular ganglion cell complex (GCC) thickness to total retinal thickness (G/T) ratio and the potential influence of race, age, macular outer retinal (OR) thickness, refractive error, intraocular pressure (IOP), mean deviation (MD) and disc area on GCC thickness between healthy European Caucasian and Japanese subjects. GCC, OR and total retinal(More)
The present study was designed to investigate the influence of axial length on macular ganglion cell complex (GCC) thickness and two ratio parameters—the GCC thickness to macular total retinal thickness (G/T) ratio and the GCC thickness to macular outer retinal thickness (G/O) ratio—using spectral-domain optical coherence tomography (OCT). In this(More)
PURPOSE To evaluate the usefulness of the spectral-domain optical coherence tomography (SD OCT)-determined ganglion cell complex thickness to total retinal thickness ratio (G/T ratio) in diagnosing glaucoma. METHODS A total of 99 eyes with primary open-angle glaucoma and 35 normal eyes were enrolled in the study. SD OCT (RTVue-100) was used to measure the(More)
PURPOSE The purpose of this study is to evaluate the applicability of a new optical coherence tomography parameter, the circumpapillary ganglion cell complex (cpGCC) thickness for glaucoma diagnostics. SUBJECTS AND METHODS The RS-3000 Advance SD-OCT (NIDEK, Aichi, Japan) was used to measure global and sector macular GCC (mGCC) thickness, circumpapillary(More)
To evaluate and compare the diagnostic performance of circumpapillary microperimetry (MP) sensitivity and circumpapillary retinal nerve fiber layer thickness (cpRNFLT) measured with optical coherence tomography (OCT) for detection of early to moderate open-angle glaucoma. Eleven eyes (11 patients) with early or moderate open-angle glaucoma and seven normal(More)
