Optical Coherence Tomography (OCT) uses a non-invasive safe beam of light with special processing to look at the structures within the retina in very high detail. The anatomic features visible with OCT are much more detailed than that seen by normal examination. Seeing the retina from this cross sectional viewpoint provides a powerful way to detect, diagnose, and treat retinal and uveal diseases as well as glaucoma.
Some of the indications for this test include:
- Diabetic macular oedema
- Macular oedema secondary to retinal vein occlusions
- Cystoid macular oedema secondary to intermediate uveitis
- Central serous retinopathy
- Age related macular degeneration
- Polypoidal choroidal vasculopathy
- Secondary Choroidal neovascular membranes (Idiopathic, myopic, inflammatory)
- Vitreo-macular tractions
-Diagnosis and follow up of Glaucoma
The only requisites for this test include a well dilated pupil and clear media. Eye drops are applied to the eye prior to the test in order to ensure good dilatation.
After dilatation. Patient is asked to place his /her chin on the chin rest and the images are acquired. Ideally the patient must avoid blinking when the images are being acquired OCT not only helps in diagnosis but also helps to make treatment as well as post treatment decisions.
Diabetic macular oedema:
OCT detects macular oedema (thickening). It measures the thickness which aids in treatment decisions. After treatment, reassessment of thickness also helps in monitoring of the disease. Monitoring the nature of vitreo- retinal interface at macula also helps in deciding the nature of treatment ( medical or surgical)
OCT identifies drusen or neovascular membrane. Likewise pathologies like sub retinal fluid (SRF) and sub retinal haemorrhage can be detected which decide whether treatment has to be initiated or not. Retreatment is also decided based on features like SRF, macular thickening or identification sub retinal haemorrhage.
Retinal vein occlusions:
OCT identifies thickness of macula. Both treatment and retreatment decisions are made based on macula thickness in consonance with visual acuity

What is OCT Angiography (OCTA)? Optical Coherence Tomography Angiography (OCTA) provides three-dimensional (3D) imaging of the anterior segment, retina, and optic nerve head. OCT-A technology uses laser light reflectance of the surface of moving red blood cells to accurately depict vessels through different segmented areas of the eye, thus eliminating the need for intravascular dyes.
Used to diagnose and manage retinal diseases which are major causes of blindness such as:

“My dad had a retinal detachment which was found overnight and he had to undergo retinal detachment surgery (vitrectomy) within 7days. He flew down to Hyderabad and directly to Raja Ram Reddy. He suggested to go for surgery the very next day. It was a successful surgery and my dad got discharged in the evening. He is very cordial and really nice in speaking. He is calm cool minded. A perfect doctor to consult.”

“I know her from since 3 years she diagnosed the retina detachment in my left eye and explained about the treatment. She works for NEORETINA eye care institute which is located in the nampally hyderabad. She clarifies each and every doubt of the patient patiently without any irritation. I mean some doctors gets irritated when the patient asks more questions but that's not the case with alka Rani madam. I suggest to all who are suffering from eye disorders to visit neoretina for timely treatment and speedy recovery.”
“Excellent attention to my eye problem doctor Abhilasha Baharani at Neo Retina Eye Care Institute was very cooperative she is very echo friendly clear voice n determined i will in sha Allah refer to all of my near n dear to visit her if any one having eye problems i appreciate thanks a lot.”
“Dr. Raja is one of the foremost experts in retina issues. He is very approachable at the same time gives you valuable advice.”
