What is Retina?
Retina is the light sensitive layer that lines the back of the eye. The retina acts like the film role of a camera. It receives the image produced by the lens and conveys these signals to the brain. The retina is actually considered to be a part of the central nervous system.
What are the conditions which are likely to affect the retina?
Retinal diseases may be inherited or acquired disorders. They can affect the young and old. Eg. Diabetic Retinopathy, Retinal Detachment, Retinal Vascular Occlusions, Age Related Macular Degeneration, Retinitis Pigmentosa, Retinopathy Of Prematurity and Retinoblastoma ( Cancer of the retina) etc.
When should I get my retina checked?
Every myope (wearing minus spectacles) must get the retina checked at least once a year. Similarly all diabetics, hypertensives, people with family history of retinal diseases must get their retina examined at least once a year even if their vision is perfectly normal. All preterm babies must get their retina checked before 1 month of age.
How do I know I have a retinal problem?
Flashes of light, floaters, distortion of images, and curtain like loss of vision may be symptoms of retinal problem. You must contact a vitro retinal surgeon immediately.
What happens when I come to the hospital for a retinal checkup?
During your visit to our hospital, you will first be taken through a routine checkup of your refraction by a team of qualified optometrists. This will be followed by dilatation of your pupils for a detailed retinal exam by a consultant. Following dilatation, it may be difficult to read or drive for several hours after the visit. You may wish to bring sunglasses and/or a driver for your vehicle. Retinal evaluations can be time consuming and often involve additional tests and treatment. If you have other systemic complaints (diabetes, hypertension etc), bring in your other medical records with details of the medications you are on.
Procedures & Services
The Vitreo retina department et TEF is well equipped with the latest instruments for the management of various vitreoretinal disorders.
Special tests and procedures for retina include:
Fundus photography – the digital color photo to document the retinal condition and aid in follow-up is available using Zeiss Visupac FF450
Fundus Fluorescein Angiography:is a test that uses special camera to photograph the structures in the back of the eye. This test is very useful for locating the damage to the blood vessels that nourish the retina and, in turn, checking on the health of the retina itself. In this test a colored dye is injected into the arm of the patient and photographs of the retina, where the dye reaches through the circulation are then clicked using the the Zeiss VisuPac FF450 plus fundus camera.
Optical Coherence Tomography: is a non invasive scan of the retina. At the Eye Foundation, we have the Carl Zeiss Spectral Domain OCT that gives us a good quality scan of the retina helping us identify and monitor a patient’s condition.
Ultrasonography: In patients who have a dense cataract or a bleed in their vitreous cavity that precludes examination of the retina, we have the facility of an ultrasound B scan that scans the eye using sound waves.
Laser photocoagulation : We offer Laser photocoagulation using the Zeiss VisuLas (frequency doubled Nd:YAG) laser for treatment of diabetic macular edema, proliferative diabetic retinopathy, retinal vein occlusions, retinopathy of prematurity, retinal holes and breaks and central serous retinopathy. The procedure is a painless outpatient treatment whereby a high intensity light beam is focused on the desired retinal area. This coagulates leaky vessels or burns out ischemic or dead retina.
Photodynamic therapy (PDT) : In patients with wet Age related macular degeneration, we offer Photo dynamic Therapy (PDT) to those suited for this modality of laser treatment.
Intravitreal injections – Drugs like
- Anti VEGF (Avastin – Bevecizumab and Accentrix – Ranibizumab)
- Steroids ( Ozurdex – intravitreal dexamethasone implant and triamcinolone)
Are given to patients whose clinical condition requires these. The injections are given as outpatient procedures and the patient can continue all his routine activities.
Retinal surgery – We have a well equipped vitreoretinal operation theatre with the latest Constellation Vitrectomy system with 7500 cut rate which allows very precise surgery even in very critical retinal conditions. We offer microincision vitrectomy surgery which is sutureless and has minimal discomfort and a faster healing time.
