PURPOSE To study the clinical profile of serpiginous choroiditis in eastern India. MATERIALS AND METHODS Ninety-one eyes of 54 patients with serpiginous choroiditis presenting to a tertiary care centre in eastern India between January 2006 and December 2010 were included in the study. Clinical presentation, treatment given, and visual outcome of the eyes were studied. RESULTS Thirty-five (6...

I developed an algorithm to count the number of axons in optic nerves automatically using Hough Transformation to detect axon edges. Due to the low quality of nerve images, a pre-process is required using Gaussian filter.

PURPOSE We tested the hypothesis that the variation of peripapillary scleral structural stiffness with age is different in donors of European (ED) and African (AD) descent. METHODS Posterior scleral shells from normal eyes from donors of European (n = 20 pairs; previously reported) and African (n = 9 pairs) descent aged 0 and 90 years old were inflation tested within 48 hours post mortem. Scl...

An observer traversing an environment actively relocates gaze to fixate objects. Evidence suggests that gaze is frequently directed toward the center of an object considered as target but more likely toward the edges of an object that appears as an obstacle. We suggest that this difference in gaze might be motivated by specific patterns of optic flow that are generated by either fixating the ce...

The efficacy of intraocular pressure reduction in retarding the progression of glaucoma has been demonstrated. This review examines the potential for prognostic advantage for glaucoma suspects in reducing their optic nerve head exposure to elevated intraocular pressure associated with activities which have been shown to elevate intraocular pressure. In this observational study, patients examine...

Intelligence data is a key component to command and control (C2) decisions. Often intelligence analysts have to provide commanders with timely data in order for them to execute their missions. The Advanced Infrared Countermeasures Assessment Model (AIRSAM) is a tool used by analysts at the National Air Intelligence Center (NAIC) to predict the most likely infrared countermeasure (IRCM) response...

A staging scheme based on ophthalmoscopic signs of disturbed axoplasmic transport is described. A study employing fundus photographs showed good reproducibility among different observers. Specificity ranged between 88% and 96%, and sensitivity between 93% and 100%.

To recognize and to assess glaucomatous changes at the optic nerve, it is important to know the characteristics of the normal optic disc. As in the other biological variables, the appearance of the optic disc varies widely among healthy individuals. This fact is complicate the recognition of the pathological changes. ‘Optic Disc’ is frequently used to describe the portion of the optic nerve cli...

We present an unusual case of a melanocytoma of the optic disc that showed documented progressive growth over a period of six years. It reached the largest size of any reported optic nerve melanocytoma and the eye was enucleated because of the possibility of malignant degeneration. Optic nerve melanocytomas are locally invasive but are not known to undergo transformation into malignant melanoma...
