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.
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.
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.
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.
The Vitreo retina department at TEF is well equipped with the latest instruments for the management of various vitreoretinal disorders.
Fundus photography – the digital color photo to document the retinal condition and aid in follow-up is available using Fundus Camera
Fundus Autofluorescence (FAF) is a new modality which allows imaging of retina and identification of retinal disorders which may not be readily apparent. Photographs are clicked without injecting any dye using the Spectralishra System. It also helps to analyze patients with vision loss of undetermined origin or those with a family history of hereditary retinal diseases.
Optical Coherence Tomography: It is a non invasive scan of the retina. At the Eye Foundation, we have the Optovue Spectral Domain OCT that uses a beam of light and its reflection to obtain 3 D cross sectional images that provide information about the different layers of the retina and choroid.
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 high-frequency sound waves.
Laser Photo Coagulation: We offer Laser photo coagulation 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
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.
Retinopathy of Prematurity (ROP) Clinic: ROP affects premature infants immediately after birth and can be a cause for blindness if not detected at appropriate time. We provide laser treatment for ROP and in advanced cases ROP related surgeries.
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.
