flow of fluid inside the eye

The natural flow of fluid inside our eyes is coming from behind the pupil, and it circulates to be drained mostly in angle in the front of the eye and then through smaller channels to outside the eye

There are two main sub-groups of primary glaucoma:

open angle glaucoma explained by Dr Ahmad Khalil Open Angle GLaucoma

Despite the angle of the eye being wide and open, the tiny microscopic drainage channels outside the angle are blocked. This leads to what we call open angle glaucoma, which is a slowly progressive condition, and because it is a slow process, it can often be missed, This is what we call "the silent thief of sight"

clodrf sngle glaucoma explained by Dr Khalil angle closure glaucoma

(also known as closed angle glaucoma): occurs more rapidly when the flow of fluid inside the eye cannot pass through the narrow angle in the front of the eye, where drainage usually occurs, causing a rapid rise in pressure inside the eye.

There are other 2 entities with some resemblance to glaucoma

  • Ocular hypertension occurs when the pressure of the eye is repeatedly measured as being high, and yet the eye displays no signs of glaucoma damage.
  • Normal tension glaucoma (normal pressure glaucoma) is the opposite, where the nerve at the back of the eye shows signs of glaucoma damage and yet the pressure is always recorded as being within normal limits.

There are some eye diseases which can result in secondary glaucoma

Among these are eye inflammatioon, the growth of new vessels inside the eye, which may occur in connection with diabetes or after vascular occlusions at the back of the eye

Congenital glaucoma

moderate congenital glaucoma case

In some rather rare instances, glaucoma can occur in young infants. This is called congenital glaucoma and can be inherited. This type of glaucoma can be devastating if not diagnosed and operated early enough.

glaucoma Treatment

Depending on the type and severity of the glaucoma, Dr Ahmad Khalil may recommend eye drops, glaucoma laser eye surgery or conventional glaucoma surgery as the best option for you. Dr Khalil almost always performs his glaucoma treatments under local anaesthetic and whichever option he recommends, the objective will be the same: to reduce the pressure causing the glaucoma and preserve the vision in your eye as safely and painlessly as possible.
