PURPOSE To evaluate the cross-sectional configurations of peripapillary atrophy (PPA)-alpha and -beta in ophthalmologically normal subjects using spectral domain-optical coherence tomography (SD-OCT). METHODS One hundred twenty normal subjects had a complete ophthalmic examination including axial length measurement, standard automated perimetry, fundus imaging with photography, and SD-OCT (3D...

Prevailing concepts of the optic nerve (ON) head (ONH) and peripapillary region have been informed by static histologic and photographic images. Consequently, most investigators have been biased to envision the ONH region as largely rigid. Sibony’s accompanying paper highlights a dynamic view, employing geometric morphometric analysis of optical coherence tomography of the ONH region in idiopat...

An unsuspected uveal melanoma arising in a phthisical eye extended through the optic nerve to the surgical margin in the orbital apex without involvement of other orbital structures. Step sections showed the continuous extension through the nerve. Factors likely to predispose to optic nerve extension include epithelioid cell type, large tumour size, peripapillary involvement, and glaucoma. Opti...

PURPOSE To analyze the normal peripapillary choroidal thickness utilizing a commercial spectral domain optical coherence tomography (OCT) device and determine the intergrader reproducibility of this method. DESIGN Retrospective, noncomparative, noninterventional case series. PARTICIPANTS Thirty-six eyes of 36 normal patients seen at the New England Eye Center between April and September 201...

Seventy randomly selected patients with Paget's disease of bone were examined for ocular complications. The prevalence of macular degeneration and cataract was 24.3%. Only one patient was found to have angioid streaks. Eight patients had peripapillary chorioretinal atrophy. These findings suggest that the prevalence of serious ocular complications of Paget's disease is not as high as previously...

Light and electron microscopic examination of the retina and optic nerve in patients with retinitis pigmentosa has revealed a larger of fibrous astrocytes (preretinal membrane) apposed to the inner limiting lamina of the optic nerve retina. This preretinal membrane was centered on the disc, was many cell layers thick over the optic nerve and peripapillary retina, and was tapered to a single cel...

This prospective study was performed to measure the macular and the peripapillary retinal nerve fiber layer (RNFL) thicknesses using optical coherence tomography (OCT) in patients with anisometropic amblyopia. Thirty-one patients with hyperopic anisometropic amblyopia were included. The macular retinal thickness and the peripapillary RNFL thickness were measured using OCT. The mean refractive e...

OttoMoncorps keratosis is a rare dermatosis, which excessive keratinization of the nipple and areola mammary gland with an unknown etiology pathogenesis. According to classification proposed by LevyFrankel in 1938, disease can be represented three types: type 1 ― variant epidermal nevus, 2 associated other diseases 3 idiopathic. The diagnosis based on data clinical picture, diffuse gland, dark ...

AIMS To observe the vascular pattern of the peripapillary circle of Zinn-Haller in humans by fundus fluorescein angiography. METHODS 307 cases (from 212 patients) of fundus fluorescein angiograms performed in patients with myopic degeneration were evaluated to find the circle of Zinn-Haller and to observe its fundus fluorescein angiographic features. RESULTS 15 cases (from 13 patients) with...

Purtscher's retinopathy is characterized by sudden visual loss in severely traumatized patients and is associated with multiple areas of superficial retinal whitening located primarily in the posterior pole. Visual outcome in Purtscher's retinopathy is variable, and there is no well-defined treatment. We report on a patient with immediate blurred vision in the right eye after a traffic accident...
