Laser treatment for all kind of Vitreoretinal diseases
Human eye is like a camera. When you take a picture with the camera, the lens allows light to pass through and focuses it on the film. When the light hits the film, picture is taken. Our eye works in the same way. The light rays from the object passes through the cornea, and lens which focus the light on the retina. On the retina an inverted image of the object is formed. Once light energy hits the retina, the photosensitive enzymes trigger a chain of impulses that travel through the optic nerve and reach the brain. Brain will read the information from both eyes, convert the electrical impulses into light impulses and fuse both images from the two eyes. That's how we see!!
What are Floaters?
You may sometimes see small specks or clouds moving in your field of vision. They are called floaters. You can often see them when looking at a plain background, like a blank wall or blue sky. While these objects look like they are in front of your eye, they are actually floating inside. What you see are the shadows they cast on the retina. Floaters can have different shapes: little dots, threads, circles, lines, clouds or cobwebs .
What are the different investigations done in Diabetic Retinopathy?
Fundus Fluorescein Angiography (FFA) and Optical Coherence Tomography (OCT) are the two investigative procedures which may be done before the treatment plan for Diabetic Retinopathy.
Fundus Fluorescein Angiography (FFA)
This is a diagnostic procedure where in fluorescein dye is injected into a vein of the hand and then a series of photographs of the patient's retina are taken. This gives us a picture of the passage of the dye through the microvasculature of the eye. This helps us to know the status of the blood vessels in retina and reveals blockage, excess leakage of the dye in case of abnormal new blood vessels. It also helps us to know whether the patient needs laser photocoagulation or not.
