Diabetic retinopathy is a complication where high blood sugar levels, over time, damage the tiny blood vessels that nourish your retina—the light-sensitive layer at the back of your eye. These damaged vessels can leak fluid or blood (like a tiny hose springing a leak) and, in advanced stages, start growing abnormally. These new vessels are fragile and can cause serious scarring.
NLDO is a blockage in the tear drainage system. Tears normally drain from the eye through small puncta on the eyelid, down a duct (the nasolacrimal duct), and into the nose. A blockage causes tears to back up and overflow.
Ptosis is drooping of the upper eyelid, affecting vision or appearance.
A chalazion is a painless eyelid cyst due to blocked meibomian glands.
Ptosis is a drooping of the upper eyelid. It can affect one or both eyes and may sometimes be noticeable or severe enough to cover the pupil and block vision. It occurs when the muscle that lifts the eyelid (levator muscle) is weak or damaged. It can happen in children in the congenital form, and in the elderly in the senile form.
This is when a small, fragile blood vessel breaks and bleeds just under the clear conjunctiva that covers the white layer of your eye (sclera). The blood gets trapped, creating a bright red patch. It looks alarming but is usually harmless and painless.
Keratitis is an inflammation or infection of the cornea. The cornea is the clear front window of the eye, so inflammation here can be painful and threaten vision. It can be caused by infection (bacteria, viruses, fungi, parasites) or by non-infectious factors like a severe dry eye, connective tissue disorders, an injury, or wearing contact lenses improperly.
Keratoconus is a progressive eye disease where the normally round, dome-shaped cornea thins and bulges outward into a cone shape. This irregular shape distorts light as it enters the eye, causing blurred and distorted vision that cannot be fully corrected with standard glasses.
A pterygium is a non-cancerous growth of fleshy tissue on the conjunctiva and cornea. It often starts on the nasal side of the eye (near the nose) and can grow slowly onto the cornea (the clear front window). It is thought to be linked to long-term exposure to ultraviolet (UV) light, wind, and dust.
