A 37-year-old Bangladeshi male presented with an inferotemporal optic disk pit and serous macular detachment in the left eye. Imaging with spectral domain optical coherence tomography (OCT) revealed a multilayer macular schisis pattern with a small subfoveal outer retinal dehiscence. This case illustrates a rare phenotype of optic disk maculopathy with macular schisis and a small outer retinal ...

shading offers hope of dense depth measurements; however, it has to contend with the spatially varying albedo of the surface of the optic disk. Fortunately, we can control the lighting and positions of the stereo pair of cameras. Section 2 describes how we can exploit this degree of freedom to apply a technique akin to homomorphic filtering to separate the contribution of albedo and reflectance...

Arcuate scotomas and occasionally severe peripheral constriction of the visual field are familiar sequelae of drusen of the optic disk. Loss of central vision with this disk anomaly is rare and its occurrence always demands additional investigations. It has been a long established rule that monocular blindness cannot be attributed to the progressive neurovascular complications of optic disk dru...

A 51-year-old woman had optic disk cupping from optic nerve compression by an intracranial aneurysm. Slit-lamp stereoscopic examination of the living eye immediately post mortem revealed an optic cup vertically oral, elongated superiorly, and indistinguishable from disk changes seen early in glaucoma. The histopathological changes differed from those in glaucoma by showing no glial atrophy. Ins...

Primary angle closure glaucoma is usually a bilateral disease, though it may be asymmetrical. However, it is unusual to see advanced glaucoma in one eye and no disk damage in the other. We present a case of unilateral angle closure glaucoma complicated by an optic disk pit and iridociliary cysts. How to cite this article: Kaushik S, Ichhpujani P, Kaur S, Pandav SS. Optic Disk Pit and Iridocilia...

PURPOSE To compare optic nerve head parameters, the thicknesses of the peripapillary retinal nerve fiber layer (pRNFL), the macular retinal nerve fiber layer (mRNFL), the ganglion cell complex (GCC), and the ganglion cell-inner plexiform layer (GCIPL) in macrodisks and normal-sized healthy disks using spectral domain optical coherence tomography. PATIENTS AND METHODS A total of 88 healthy eye...

Introduction. Differentiating pseudopapilledema from papilledema which is optic disk edema and a result of increased ICP (intracranial pressure) is important and can be done with noninvasive methods like orbital ultrasound examination. Method. This was a cross-sectional study in which patients with optic nerve head swelling were referred for LP exam after optic nerve head swelling diagnosis con...

The term optic neuritis denotes primary inflammation of the optic nerve. When the clinical history and examination suggest optic neuritis and the optic disk appears normal, the term retrobulbar optic neuritis is used. Critical elements in establishing the diagnosis are a detailed history and an accurate examination. For this reason, the ophthalmologist must be familiar with the clinical profile...

Optic disk segmentation plays a key role in the mass screening of individuals with diabetic retinopathy and glaucoma ailments. An efficient hardware-based algorithm for optic disk localization and segmentation would aid for developing an automated retinal image analysis system for real time applications. Herein, TMS320C6416DSK DSP board pixel intensity based fractal analysis algorithm for an au...
