Diagonostic Testing

This diagnostic procedure allows the doctor to visualize the Retinal blood vessels and diagnose diseases of Retina.

How is the test performed?

The eye is dilated first. A dye (Fluorescein) is injected in the vein of your hand and color photographs of the retina are clicked as the dye passes through the eye which is for approximately 10-15 minutes.

What to expect during procedure?

Bring an attender along with you for the procedure. Urine may be orange colored for 24 hours after the procedure. There may be feeling of nausea during the procedure or rarely itchy skin due to allergy. Inform the doctor if you have any allergic  reactions in the past.


OCT is a commonly performed diagnostic test to identifying Retinal Diseases.

It is similar to CT Scan of the body. Providing a microscopic view of Retina with resolution of 5 microns. It is a non-invasive procedure and helps in monitoring disease progression and efficacy of treatment done.


High frequency sound waves are used to examine the Retina and underlying structures when clear view is obstructed due to Cataract or Vitreous Hemorrhage.


This test is similar to Fluorescein Angiography and sometimes complimentary and to FFA and provides additional information helping to visualize & identify diseases of choroid like CNV, IPVC, RAP, Intraocular Tumors.

Indocyanine green dye is injected in the vein of hand and photographs are taken within the eye.


Simple test where color photograph of the retina is taken in all quadrants and used for evaluation of disease progression and patient education & documentation purpose.

Color Fundus Photography

This test is needed to asess functional vision. Visual acuity  on snellen chart tests high contrast. However in real life situations when contrast is low, people may be visually handicapped like  during  night driving.  reading  in dim light ,. contrast sensitivity is useful as it tests to provide exactly this information. In many Retinal Dieases contrast sensitivity decrease is seen in early stages of the disease. Eg: Diabetic Retinopathy and Optic Neuropathy.
