PURPOSE To verify the effect of the scan angle of the optic nerve head (ONH) on measurements of peripapillary retinal nerve fiber layer (RNFL) thickness by using spectral-domain optical coherence tomography (OCT). METHODS Both eyes of 64 healthy volunteers were scanned by the optic disc cube 200 x 200 scan of a spectral-domain OCT system. Ultra-high resolution OCT images of the ONH were used ...

PURPOSE To evaluate the clinical features of peripapillary microvasculature in myopic eyes and investigate the association between the superficial and deep peripapillary microvascular density and the myopic optic disc characteristics. MATERIALS AND METHODS This cross-sectional study included one hundred and fifty healthy myopic eyes with β-peripapillary atrophy (β-PPA). Ovality index, degree ...

Purpose To compare the sectoral structure-function relationships in glaucoma between two structural parameters, vessel density (VD) and thickness, in the peripapillary retinal nerve fiber layer (RNFL). Methods Optical coherence tomography (OCT) angiography (AngioVue/RTVue-XR) for VD and OCT (RS-3000) for peripapillary RNFL thickness were performed in 129 eyes from 129 subjects (94 glaucoma, 1...

Congenital fibrosis of the extraocular muscles (CFEOM) is a congenital cranial dysinnervation disorder caused by developmental abnormalities affecting nerves/nuclei innervating muscles. Autosomal dominant CFEOM arises from heterozygous missense mutations KIF21A or TUBB3. Although spatiotemporal expression studies have shown and TUBB3 in developing retinal ganglion cells, it unclear whether exte...

PURPOSE To compare the diagnostic abilities of vessel density measurements of the optic nerve head (ONH), peripapillary and macular regions on optical coherence tomography (OCT) angiography in eyes with primary open angle glaucoma (POAG) with that of the ONH rim area, peripapillary retinal nerve fiber layer (RNFL) thickness and the macular ganglion cell complex (GCC) thickness measurements. M...

purpose : to evaluate the correlations between visual field (vf) defects with retinal nerve fiber layer (rnfl) thickness in nonarteritic anterior ischemic optic neuropathy (naion) eyes, compare different gdx parameters with the other healthy contralateral eyes, and calculate receiver operating characteristic (roc) curve for the gdx parameters methods : eighteen patients with unilateral naion fr...

Background: It has been believed that diabetic retinopathy (DR) is a microvascular disorder. Recent research linked DR to both neuronal and processes. The purpose of this was use optical coherence tomography angiography (OCTA) compare the thickness peripapillary area retinal nerve fiber layer (pRNFL) in different stages.Methods: This cross-sectional controlled carried out on 40 subjects Cases w...

Objective—To study retinal morphological changes around the optic disc in patients with peripapillary atrophy (PPA) with high-resolution spectral domain optical coherence tomography (SD OCT). Design—Cross-sectional, retrospective analysis Participants—One hundred and three eyes of 73 patients with PPA and 21 eyes of 12 normal patients seen at the New England Eye Center, Tufts Medical Center bet...

Amblyopia is the most common cause of monocular visual impairment in both children, and young to middle-aged adults, affecting 2%–5% general population. The objective this study was compare peripapillary nerve fiber thickness macular amblyopic eyes, fellow eyes normal control using spectral domain optical coherence tomography. This a cross-sectional observational conducted at R M Kedia Eye Hosp...

Aims. To compare optical coherence tomography angiography (OCT-A) retinal vasculature measurements between normal and optic atrophy after nonarteritic anterior ischemic optic neuropathy (NAION) subjects. Design. This prospective observational study was conducted between July 2015 and August 2016 at the ophthalmology outpatient department of a referral center in Taiwan. Peripapillary (4.5 × 4.5 ...
