RETINA TREATMENT SERVICES
Majority of retinal diseases are symptomless and have non-noticeable symptoms in their initial stage, the stage at which they can be treated with best results. Therefore, timely detection of retinal diseases is a vital part of eye care. It becomes very important for patients, particularly those at increased risk, to get routine screening by medical as well as surgical retina specialists who are accomplished in detecting and treating these disorders.
What is Retina?
It is the delicate and thin light sensitive layer at the back of your eye. It consists of millions of special light sensitive cells that are called photoreceptors. These photoreceptors capture light and convert it to electric impulses which are directed to your brain via optic nerve. Once these electric impulses reach brain, they are seen as images. Any disease in retina interrupts this process and leads to disturbance or loss in vision.
So far, retinal diseases are the leading cause of irreversible loss of sight in adults, all over the world.
Who is at Risk of Retinal Diseases?
You need a dilated examination and screening for Retinal Diseases if you are Diabetic, Hypertensive, or short sighted and wear “minus glasses”.
You also need to get retina checked if you are experiencing symptoms like hazy vision, distorted reading, floaters (black spots or cob webs hanging in your field of view), flashes (sparking of light!) or if you suffer from cancer, immunological diseases like Rheumatoid or Sarcoidosis or eye injury.
Besides this if your vision is getting hazy again after cataract surgery or you were born premature, then also you need retina examination.
WHAT IS DIABETIC RETINOPATHY?
Diabetic retinopathy is a condition in which diabetes damages the blood vessels in the eye and causes them to leak. This can result in vision complications and even vision loss.
WHAT ARE THE CAUSES?
Individuals with Type 1 and Type 2 diabetes are at risk for diabetic retinopathy, which occurs when elevated levels of blood sugar weaken the blood vessels in your eyes. In turn, these weak blood vessels leak fluid into your eye and blur your vision.
WHO GETS DIABETIC RETINOPATHY?
People with diabetes who do not keep their blood sugar under control are the most likely candidates to develop diabetic retinopathy.
Symptoms of Diabetic Retinopathy
Diabetic Retinopathy may be developing even when your sight is good. This disease can progress to the most advanced stages without any noticeable change in vision.
Symptoms of Diabetic Retinopathy may include:
• ‘Spiders’, ‘cobwebs’ or tiny specks floating in your vision
• Dark streaks or a red film which blocks vision.
• Vision loss or blurred vision.
• A dark or empty spot in the center of your vision.
• Poor night vision
• Difficulty adjusting from bright light to dim light.
HOW CAN DIABETIC RETINOPATHY BE TREATED?
Diabetic retinopathy is far easier to treat and has fewer complications when caught early. Our diabetic retinopathy specialists conduct a comprehensive eye examination to detect and access severity of diabetic retinopathy through extensive tests like Fundus Fluorescein Angiography (FFA) and Optical Coherence Tomography (OCT), etc.
The treatment is based on factors like stage of the disease, age of the patient and recommendations of the retina specialist.
Of course, maintaining a healthy diet and exercising regularly will help prevent and fight off the effects of diabetic retinopathy, but there is no sure-fire fix. Surgery may help with serious cases of diabetic retinopathy. Laser treatment has proven to be very effective at sealing leaking blood vessels, but success of this surgery can vary depending on how long the leak has been there. Laser surgery may be performed in an out-patient clinic and can greatly reduce the chances of severe visual impairment. Intraocular Steroid Injection is a newly emerging treatment for diabetic macular edema. This therapy helps reduce the amount of fluid leaking into the retina, resulting in visual improvement. Advanced cases of retinopathy require vitreous surgery to restore vision.
Along with eye care, controlling blood pressure, maintaining normal cholesterol levels and treating anemia can also prevent or significantly reduce progression of diabetic retinopathy.
The Vitreoretina service at Umaprem Netralay Eye Hospital is a major referral center which deals with the management of diabetic retinopathy, retinal detachment, ARMD, infections, trauma & various other retinal disorders.
A well trained team of retinal surgeons combined with the effective use of latest diagnostic tools (FFA, Ultrasound B Scan, OCT and Visual Electrophysiological Tests such as ERG, multifocal ERG) get us optimal visual results. Clinical trials are underway to evaluate newer drugs and treatment options.
An exclusive retinal examination may be different than a routine eye exam. It involves dilation of your pupils, examination by the specialist and diagnostic testing if required. It may take about three hours for the complete examination. If treatment is recommended for your condition, please allow for some extra time in our office to perform the procedure. Surgical intervention if required can be scheduled at an appropriate time, depending on your condition.
Dilation enlarges your pupils to allow the doctor a better view inside your eye. It is important to know that your vision will be blurred and you will be sensitive to light (photophobic) for several hours following this. Therefore, we recommend that you bring sunglasses and not drive after your appointment.
Most diagnostic tests that the doctor may order to evaluate your eye condition can be performed in the outpatient on the same day.
Many of the procedures (treatments) that may be recommended to treat your condition can be performed by the doctor in the outpatient as well.
We also have a well equipped operation theatre for vitreoretinal surgery. Our doctors and staff will gladly answer your questions and assist you by scheduling any surgical or follow up care needed.
