A cataract is defined as the clouding of the eye’s natural clear lens. The lens focuses light rays on the retina to produce a sharp image. When the lens becomes cloudy, light rays cannot pass through it easily, and vision is blurred.
If you have diabetes mellitus, your body does not use and store sugar properly. High blood sugar levels can damage blood vessels in the retina and the nerve layer at the back of the eye. Such damage to retinal vessels is referred to as diabetic retinopathy.
Normally, the eye constantly bathes itself in tears. By producing tears at a slow and steady rate, the eye stays moist and comfortable. Sometimes people do not produce enough tears or the appropriate quality of tears to keep their eyes healthy and comfortable. This condition is known as dry eye. The eye uses two different methods to produce tears. It can make tears at a slow, steady rate to maintain normal eye lubrication. It can also produce large quantities of tears in response to eye irritation or emotion. When a foreign body or dryness irritates the eye or when a person cries, excessive tearing occurs.
You may sometimes see small specks or clouds moving in your field of vision. These are called floaters. You can often see them when looking at a plain background such as a blank wall or blue sky. Floaters are actually tiny clumps of gel or cells inside the vitreous (the clear gel-like fluid that fills the inside of your eye). While these objects look like they are in front of your eye, they are actually floating inside it. What you see are the shadows they cast on the retina (the layer of cells lining the back of the eye that senses light and allows you to see). Floaters can appear in different shapes such as little dots, circles, lines, clouds, or cobwebs.
The human eye in many ways is similar to a camera. Like the camera, the eye lenses too focus images on the retina. The eye has two lenses: the cornea and “the lens.” The cornea, which is the first element in the visual pathway, provides about 2/3rd of the focusing power of the eye. Sometimes in some unfortunate persons, there is a mismatch between the focusing power of the cornea and the lens and the length of the eye. In these circumstances, the eye focuses images in front of or behind the retina. This results in unclear vision, eyestrain, and headaches. The person is said to have a refractive error and needs to wear spectacles or contact lenses for clear vision.
Glaucoma is a disease of the optic never-the part of eye that carries the images we see to the brain. The optic nerve is made up of many never fibers, like an electric cable that consists of numerous wires.
Paediatric Ophthalmology is a highly specialised eye care for young children. The Doctor is experienced in examining the eye of the children and diagnosed congenital or age related eye diseases in the young.
Did you know that lining the back of your eye is a thin membrane—only .5 to 1 mm thick—with profound implications for your ability to see the world around you? Despite its small size, this membrane, known as the retina, is a crucial tool for sending messages to the brain to help us process what we see! The retina is a thin layer of tissue that lines the back of the eye on the inside. It is located near the optic nerve. The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition. Due to the retina’s vital role in vision, damage to it can cause permanent blindness. Conditions such as retinal detachment, where the retina is abnormally detached from its usual position, can prevent the retina from receiving or processing light. This prevents the brain from receiving this information, thus leading to blindness. Our retinal surgeon specializes in diagnosing and treating retina conditions such as diabetic retinopathy, age-related macular degeneration (AMD) and retinal detachment, all of which can lead to vision loss or blindness. Common retinal conditions include floaters, macular degeneration, diabetic eye disease, retinal detachment. There are other issues that can occur, but these conditions are some of the most common and serious that a person can experience.
