Diabetes & Retina Services

Diabetes causes eye problems and may lead to blindness. People with diabetes do have a higher risk of blindness than people without diabetes.

What is the Retina?

The retina is the inner most layer of the eye which receives the light entering the eye. The retina sends the light signal to the brain through the Optic nerve. One part of the retina is specialized for seeing fine detail. This tiny area for sharp vision which is required for reading, writing and color differentiation is called the macula.

Eye Problems Due to Diabetes:

Diabetic Retinopathy

Diabetic retinopathy is a general term for all diseases of the retina caused by diabetes. There are two stages of retinopathy: nonproliferative and proliferative.

Treatment for Cataract

cataract-treatmentIn the early stages, you can improve your vision by changing your glasses. But once the cataract progresses, changing glasses will not help. There are no medications, eye drops, or diet changes that can cure or prevent cataract formation. If the cataract decreases vision, the only solution is surgery. DO NOT WAIT FOR THE CATARACT TO GET MATURE as unnecessary delay can lead to avoidable complications and more difficult surgery. Cataract surgery can be undertaken successfully in any season. Summer or rainy season do not have any effect on the outcomes of the cataract surgery

Symptoms and Detection

  • No symptoms in the early stage of Diabetic Retinopathy
  • Fluctuating vision
  • Eye floaters: which can look like black spots, little threads, or cobwebs?
  • Blurry and or distorted vision
  • Double vision
  • Eye pain due to secondary glaucoma
  • Cataracts
  • Total loss of vision

Diagnostics & Treatment Facilities

  • Amrit Hospial has a fully equipped speciality clinic to manage diabetic retinopathy and all other retinal disorders
  • Heine Indirect Ophthalmoscopy: To examine the Retina till the periphery
  • 90 D Slit-Lamp Ophthalmoscopy: To examine the central retina and macula
  • Topcon digital Fundus Angiography & color photography (Japan): to study the blood vessels of the retina and to identify the leaking vessels.
  • Iridex green Laser System (USA): For treating the leaking blood vessels and damaged retina.
  • Anti VEGF pharmacotherapy

Fundus Fluorescein Angiography (FFA)

Fundus-Fluorescein-AngiographyThis is a diagnostic procedure where Fluorescein dye is injected into a vein of the hand and then a series of photographs of the patient’s retina are taken. This helps us to know the status of the blood vessels in retina and shows the abnormal leaking vessels and abnormal new blood vessels. The treatment is decided following this Investigation.

What is the treatment of the Diabetic Retinopathy?

The treatment is usually in the form of laser (Photocoagulation) or rarely an injection (Anti-VEGF) is given in the eye.

Photocoagulation:

Involves focusing and applying laser spots on the retina to seal the leaking and blood vessels. The aim of this treatment is to protect central vision. It does not restore lost vision, but it can prevent further deterioration, which is why early diabetic retinopathy diagnosis through regular eye examination is important.

The laser treatment may be done in 1- 3 sittings

What are Anti VEGF agents, and what is their role in managing diabetic retinopathy?

Anti VEGF agents (Avastin, Macugen) are emerging as the new modality of treatment for various stages of diabetic retinopathy. These agents are injected into the eye (intravitreal injection). They are commonly used in diabetic maculopathy and proliferative diabetic retinopathy.

How frequent should a diabetic have eye check up?

Every patient once diagnosed to have diabetes should have regular eye checkups every 6 months or more frequently depending on the severity of the disease.
