Glaucoma is a disease affected by an eye which results normally and impaired by the normal optic nerve. It is caused by increase in the pressure which utilize across the outer coats of the eye ball. Glaucoma primarily causes a retinal vessel occlusion and then it alters the optic disc by getting higher the cup size. The blindness will lead to causes and it will detect some problems and treated ...

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...

BACKGROUND Laser speckle flowgraphy (LSFG) enables noninvasive quantification of the retinal circulation in glaucoma patients. In this study, we tested the intrasession reproducibility of LSFG-NAVI, a modified LSFG technique. METHODS Sixty-five eyes from 33 subjects (male (M):female (F) = 17:16) with a mean age of 49.4 ± 11.2 years were examined in this study. Two parameters indicating reprod...

We analyzed the long-term functional results in 102 eyes of 59 patients with childhood glaucoma with specific reference to the pattern of optic nerve damage. Optic disk photography and quantitative perimetry were used to judge the degree of damage that had been sustained. There was a predilection for initial visual field damage in the arcuate area, followed by further arcuate and nasal field lo...

The methods of active contours (“snakes”) and level sets were applied to images of the retina in order to locate the outer boundary of the optic disk. A gradient-vector-flow based active contour was used as it performed well over a large range of initial conditions. Images were pre-processed to lessen the influence of blood vessels on boundary detection. Both active contours and level set metho...
