PURPOSE To observe changes in fundus autofluorescence 2 years after implantation of blue light-filtering (yellow-tinted) and ultraviolet light-filtering (colorless) intraocular lenses (IOLs). SETTING Department of Ophthalmology and Visual Science, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan, and the Department of Ophthalmology, University of Bern, Bern, Switzerla...

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...
