Specialist Doctors :
Diabetic retinopathy is a complication of diabetes and a leading cause of blindness. It occurs when diabetes damages the tiny blood vessels inside the retina, the light-sensitive tissue at the back of the eye. A healthy retina is necessary for good vision. If you have diabetic retinopathy, at first you may notice no changes to your vision. But over time, diabetic retinopathy can get worse and cause vision loss. Diabetic retinopathy usually affects both eyes.
Age related macular degeneration
In macular degeneration, the light-sensing cells of the macula malfunction and may over time cease to work. Macular degeneration occurs most often in people over 60 years old, in which case it is called Age Related Macular Degeneration (ARMD). Much less common are several hereditary forms of macular degeneration, which usually affect children or teen-agers. Collectively, they are called Juvenile Macular Degeneration. They include Best's Disease, Stargardt's Disease, Sorsby's Disease and some others.
Flashes and floaters
Light flashes are sometimes caused by mechanical stimulation of the retina, often referred to as "pulling", "forces", or "traction".
A variety of conditions can cause it, including: posterior vitreous separation,retinal tears (breaks), and scarring on the surface of the retina.Some macular disease patients experience flashes in the central field of vision (straight ahead vision).
Patients with successfully repaired retinal tears and detachments may have flashes for many months.
Retinal detachments often develop in eyes with retinas weakened by a hole or tear. This allows fluid to seep underneath, weakening the attachment so that the retina becomes detached - rather like wallpaper peeling off a damp wall. When detached, the retina cannot compose a clear picture from the incoming rays and vision becomes blurred and dim.
Retinal arterial blocks
A retinal artery occlusion occurs when the central retinal artery or one of the arteries that branch off of it becomes blocked. This blockage is typically caused by a tiny embolus (blood clot) in the blood stream. The occlusion decreases the oxygen supply to the area of the retina nourished by the affected artery, causing permanent vision loss. Retinal artery obstruction is like a stroke in the eye. the damage can be relatively mild or quite severe, depending on the extent to which the blood flow has been disrupted.
Retinal venous blocks
Central retinal venous blocks occur when there is a congestion to blood flow and an increase in backpressure on the central retinal vein. It causes variable degree of visual loss and can be easily diagnosed by a retinal examination. It is commonly seen in hypertensives and diabetics. Some times it can be seen in people with clotting abnormalities also.
Other Disorders treated are:
- Vitreous hemorrhage
- Cystoid macular edema
- Macular hole
- Retinitis pigmentosa
- Posterior uveitis
- Ocular trauma
- Intraocular tumours
- Central serous retinopathy
Procedures & Equipment
OPD procedures frequently done
- Indirect Ophthalmoscopy- To have a detailed 3 dimensional view of the retina till the periphery. The patient is asked to lie down and with an indirect ophthalmoscope, we look at the periphery of the retina. Sometimes, it may ne needed to press on the lids to see the extreme periphery. It is painless, but may cause slight discomfort as bright light is shone into the eyes.
- Contact and noncontact stereo biomicroscopy- This is done for a detailed 3 D examination of the macula and optic nerve and to look at the vitreo retinal interface.
- Digital fundus camera and imaging – We can take serial pictures to evaluate any subtle changes that may occur with time. A key for all diseases in which we may require observation.
- Fundus Fluorescein angiography- The corner stone of medical retinal diagnosis. Here a dye is injected into the veins of the hand and serial pictures are taken with the fundus camera. The patient will sit with the chin and forehead apposed against the machine.
- Optical coherence tomography- A revolution that has improved our understanding of all retinal diseases. This offers an anatomic diagnosis at tissue level and is also nicknamed, bloodless histopathology
- Ultrasonography and ultrasound biomicroscopy- Standard care for retinal diagnosis in hazy media like cataract and vitreous hemorrhage. An ultrasound biomicroscopy offers view to the extereme periphery of the retina like pars plana and ora serrata as well as the anterior segment and angle structures.
- Humphrey visual field examination- This method of examination is automated visual fields which can offer great help in the functional quantification of the defects in visual function caused by macular pathologies.
- Short wavelength automated perimetry- Blue on yellow perimetry can have more accuracy than white on white fields in the diagnosis of specific conditions.
- Green laser photocoagulation
- Laser indirect Ophthalmoscopy- Is used when we want to laser the extreme periphery, ROP, recent post operative cases etc.
