Retinal Tear : A retinal tear occurs when the clear, gel-like substance in the center of your eye (vitreous) shrinks and tugs on the thin layer of tissue lining the back of your eye (retina) with enough traction to cause a break in the tissue. It's often accompanied by the sudden onset of symptoms such as floaters and flashing lights.
Retinal Detachment : A retinal detachment is defined by the presence of fluid under the retina. This usually occurs when fluid passes through a retinal tear, causing the retina to lift away from the underlying tissue layers.
Macular Hole : A macular hole is a small defect in the center of the retina at the back of your eye (macula). The hole may develop from abnormal traction between the retina and the vitreous, or it may follow an injury to the eye.
In Phaco technique, a small incision is placed in the eye, and a hollow Phaco needle is introduced through the opening. On giving energy through the tip of the Phaco needle, the cataract lens gets dissolved and is sucked out through this needle. An artificial lens called a foldable Intra-ocular lens is now injected through this small opening. Once inside the eye, it opens up and serves to replace the original lens. Since the eye-opening is very small and designed specially, it self-seals, and no sutures are required. Hence this procedure is also popularly known as “Stitchless” cataract surgery.
Glaucoma is a condition that damages your eye's optic nerve. It gets worse over time. If the damage worsens, glaucoma can cause permanent vision loss or even total blindness within a few years. Most people with glaucoma have no early symptoms or pain. Visit your eye doctor regularly so they can diagnose and treat glaucoma before you have long-term vision loss.
It mostly affects adults over 40, but young adults, children, and even infants can have it. African American people tend to get it more often, when they're younger, and with more vision loss.
