The surgery done to remove the vitreous gel from the eye is called as Vitrectomy. The vitreous may need to be removed in order to safely access the abnormal retinal tissue or at times the vitreous itself may be abnormal. The technique of vitrectomy has come a...
The procedure of injecting a drug directly in the gel of the eye (vitreous) is known as an intra-vitreal injection. This method delivers the necessary concentration of a drug as close to the retina as possible. Although it may be performed as an outpatient procedure, we...
Lasers are specialised narrow beams of light that have the ability to precisely focus on the target area. Due to the precise control they offer in the hands of the surgeon, they have been used for various purposes in medicine, especially in Ophthalmology. There are various types...
Central serous chorioretinopathy is when fluid builds up under the macula. Normally there is an RPE (retinal pigment epithelial) pump in the retina that prevents any fluid from accumulating. When the RPE pump does not work as it should, fluid builds up under the RPE....
The retina has one main artery and one main vein to carry blood to and fro. When the main retinal vein becomes blocked, it is called central retinal vein occlusion (CRVO). When branches (tributaries) of the retinal vein become blocked, it is called branch retinal vein...
Colour blindness means inability to see colours in a normal way. Most commonly there is difficulty to distinguish between greens and reds and occasionally blues. In the retina there are three types of cone cells that see colour: red, green and blue. Colour blindness can occur...
Floaters look like small hair-like or mosquito-like or cobwebs in the field of vision, especially when looking at something plain and light coloured (like a blank wall or a blue sky). While they seem to be in front of the eye, they are actually floating...
Macula is the central, most vital part of the retina. Macular hole is when a tear or opening forms in the macula. As the hole forms, things in the central vision look blurry, wavy or distorted. As the hole grows, a dark or blind spot...
Epi-Retinal Membrane (ERM) is a thin layer that can develop on the central part of the retina. Over a period of time it may grow and lead to wrinkles, creases or bulges on the macula causing the central vision to be affected. Things look wavy...
In certain diseases of the eye, a body chemical called VEGF (Vascular Endothelial Growth Factor) is released. This VEGF causes abnormal blood vessels to grow in the retina which tend to leak and affect the vision. Drugs that block the trouble-causing VEGF are called anti-VEGF...
