Vitreo Retina care
The vitreo-retinal dept goes pari-passu with the concept of complete and holistic examination of the diabetic patient.
The retina contains many small blood vessels which get altered in diabetes and herald the onset of the severity of the disease. Since it is the only tissue in the human body with ultra-structural changes that can be viewed by the naked eye, it forms the back-bone for diabetic examination in patients.
The vitreo-retinal dept in KID has the latest and most modern equipments to aid the diagnostician in coming to a conclusion regarding the status of diabetes and its eye related complications. We have 2 consultants full-time and a host of back up personnel to aid in the daily working of the dept.
Slit-lamp examination
This is an instrument consisting of a high-intensity light source that can be focused to shine a thin sheet of light into the eye. Hence the term "slit-lamp".
It is used in conjunction with a biomicroscope.
It facilitates the examination of the anterior segment, or frontal structures, and posterior segment, of the human eye, which includes the eyelid, sclera, conjunctiva, iris, natural crystalline lens, and cornea, which form the anterior segment, as well as the vitreous and retina and optic nerve, which form the posterior segment of the eye.
Non-contact Tonometer
A tonometer is an instrument for measuring tension or pressure.
In ophthalmology, tonometry is the procedure performed to determine the intraocular pressure (IOP), the fluid pressure inside the eye.
Non-contact tonometry or air-puff tonometry was invented by Bernard Grolman of Reichert, Inc (formerly American Optical). It uses a rapid air pulse to applanate or flatten the cornea.
Corneal applanation is detected via an electro-optical system. Intraocular pressure is estimated by detecting the force of the air jet at the instance of applanation.
Non-contact tonometers are a fast and simple way to screen for high IOP. Modern non-contact tonometers have been shown to correlate well with Goldmann tonometry measurements and are particularly useful for measuring IOP in children and other non-compliant patient groups.
Non-contact tonometry is accomplished without the instrument contacting the cornea which reduces the potential for disease transmission.
PASCAL (PAtterned SCAnning Laser)
The PASCAL (PAtterned SCAnning Laser) method is a semi-automatic pattern scan laser system designed to treat ocular diseases using a single shot or predetermined pattern array.
The laser source such as the Nd:YAG laser is used in Pascal
The Pascal system is fully integrated with a touch screen GUI, advanced slit lamp optics, slit lamp mounted micromanipulator, and ergonomic features for the physician and patient.
Optical Coherence Tomography(OCT)
Optical coherence tomography is the examination of a slice of the inner eye under a high-powered microscope, to determine any vision problem…without even touching the eye! It is a non-invasive technology used for imaging the retina, the multi-layered sensory tissue lining the back of the eye.
OCT, is the first instrument to allow doctors to see cross-sectional images of the retina, in the early detection and treatment of eye conditions.
Similar to CT scans of internal organs, OCT uses the optical backscattering of light to rapidly scan the eye and describe a pixel representation of the anatomic layers within the retina. Each of these ten important layers can be differentiated and their thickness can be measured. In essence, it uses light waves to produce images of the retina
much like sound waves in ultra-sonography.
B scan ophthalmic ultrasound
It is a technique used to image the posterior segment of the retina, when the access to anterior viewing is limited by opacities in the media.
It uses sound waves of very high frequency to enter the eye and reflect back from the retina.
The reflected waves are analysed and displayed to diagnose the posterior involvement of the eye in any disease. It also helps in making crucial surgical decisions.
Fundus Photography
The fundus is a term used to describe the posterior part of the eye otherwise known as the retina. This equipment is a sophisticated camera that captures the images of the retina through the dilated pupil.
It helps to photograph the disease, its progress and response to treatment.
Fundus Fluorescein Angiography
The retina is photographed after a dye is injected into the peripheral vein. It takes only 5 – 8 minutes but scans the entire retina as the dye passes through each portion. Digital photographs are taken to display the blood vessels at the posterior section of the eye. It shows any abnormal blood vessels and any leaking spots causing the eye problems.
It helps to confirm the diagnosis and decide on the treatment. It also helps to evaluate the effects of treatment given.
