Fundus examination
Fundus Examination : The fundus of the eye is the interior surface of the eye opposite the lens and includes the retina, optic disc, macula, fovea, and posterior pole. The fundus can be examined by ophthalmoscopy and/or fundus photography. The term fundus may also be inclusive of Bruch's membrane and the choroid., Vedanta Netralaya Expertise in the subject makes it Retina Specialist in GhaziabadIndirect ophtlamoscopy
Ophthalmoscopy is a routine exam done by ophthalmologists to examine the inside of the back of the eye, also known as the fundus or posterior segment. Although there are several types of ophthalmoscopy, we will focus on Binocular Indirect Ophthalmoscopy or BIO, for short, in this article. BIO is one of the ways used to view the retina, with a wide field of the retina and stereoscopic view. BIO also allows dynamic observation of the retina by moving the BIO device, lens, and applying scleral depression. The process is “indirect” because the fundus is viewed through a hand held condensing lens.Vedanta Netralaya Expertise in the subject makes it Retina Specialist in GhaziabadFFA (angiography)
It is a technique for examining the circulation of the retina and choroid (parts of the fundus) using a fluorescent dye and a specialized camera. Sodium fluorescein is added into the systemic circulation, the retina is illuminated with blue light at a wavelength of 490 nanometers, and an angiogram is obtained by photographing the fluorescent green light that is emitted by the dye. The fluorescein is administered intravenously in intravenous fluorescein angiography (IVFA) and orally in oral fluorescein angiography (OFA). The test is a dye tracing method.Vedanta Netralaya Expertise in the subject makes it Retina Specialist
