Magnified red-free photography reveals distinct differences in the appearance of the peripapillary retinae in two commonly confused conditions. Eyes with congenitally blurred disc margins have normal striated nerve fiber bundle patterns and glistening vascular highlights that are also visible with a direct ophthalmoscope and a bright red-free light source. In eyes with incipient papilledema, th...

Background: The study was conducted to evaluate the role of fundus fluorescein angiography (FFA) and spectral domain-optical coherence tomography (SD-OCT) in choroidal neo-vascularisation (CNV).Methods: This a hospital based prospective carried out post-graduate department ophthalmology, SKIMS medical college, Bemina, Srinagar, Jammu Kashmir. All patients diagnosed with CNV fulfilling criteria ...

The effect of topical carteolol 1%, a beta-adrenergic blocker with intrinsic sympathomimetic activity, on the retinal circulation was investigated in 15 normal subjects using laser Doppler velocimetry and monochromatic fundus photography. In a double-masked randomized design, one eye received one drop of carteolol 1% and the fellow eye one drop of placebo. Vessel diameter, maximum erythrocyte v...

The closure of 2 or more vortex veins in rabbits' eyes results in a persistent rise in intraocular pressure. In these circumstances a small opening into the anterior chamber at the corneoscleral limbus resulted in an iris prolapse, while a larger limbal wound was immediately followed by a massive choroidal expulsive haemorrhage. It appears from this experimental study that a definite and persis...

Imaging techniques for the eye include fundus camera, OCT etc of which the most widely used and economical one is the use of fundus camera. Images obtained from this camera are 2D in nature. Analysis of 2D data requires a lot of expertize. This makes it necessary for a 3D reconstruction of the 2D fundus image which would help doctors in their analysis and treatment plan. 3D retinal image would ...

We investigate the utility of infrared fundus examination in a case of lecithin cholesterol acyltransferase (LCAT) deficiency. A 57-year-old woman presented with blurred vision in both eyes. Her eyes had been grayish blue since a young age. She was diagnosed as LCAT deficiency at the age of 50. Slit-lamp examination revealed diffuse bilateral opacity of the corneal stroma. Because of the hazy v...

Ocular fundus examination is a fundamental component of the neurologic examination. Finding papilledema in headache patients or retinal arterial emboli in stroke patients can be extremely useful. Although examination of the ocular fundus with a direct ophthalmoscope is an important skill for all neurologists, it is rarely and unreliably performed. Nonmydriatic ocular fundus photography, which a...

introduction: diabetic retinopathy (dr) is the single largest cause of sight loss and blindness in the working age population of western countries; it is the most common cause of blindness in adults between 20 and 60 years of age. early diagnosis of dr is critical for preventing vision loss so early detection of microaneurysms (mas) as the first signs of dr is important. this paper addresses th...

Fundus images are critical data to record visual health and play an important role in the diagnosis of ocular diseases. Therefore, protecting the copyrights of those valuable data becomes an important issue in telemedicine applications where fundus images are exchanged across different hospitals and medical institutes. In this paper, a novel lossless fingerprinting-watermarking hybrid scheme is...

Visual features extracted from retinal fundus images have been increasingly used for glaucoma detection, as those images are generally easy to acquire. In recent years, genetic researchers have found that some single nucleic polymorphisms (SNPs) play important roles in the manifestation of glaucoma and also show superiority over fundus images for glaucoma detection. In this work, we propose to ...
