Overview
Causes
The four major types of glaucoma have their own unique causes. Specific causes by each major type of glaucoma are:
Open-angle (chronic) glaucoma
- The cause is unknown. An increase in eye pressure occurs slowly over time. The pressure pushes on the optic nerve and the retina at the back of the eye.
- Open-angle glaucoma tends to run in families. Your risk is higher if you have a parent or grandparent with open-angle glaucoma. People of African descent are at particularly high risk for this disease.
Angle-closure (acute) glaucoma
- It occurs when the exit of the aqueous humor fluid is suddenly blocked.
- Dilating eye drops and certain medications may trigger an acute glaucoma attack.
- Medication Side Effect- Lisinopril and Hydrochlorothiazide, Losartan potassium and Hydrochlorothiazide, Paroxetine
Congenital glaucoma'
- It is present at birth and results from the abnormal development of the fluid outflow channels in the eye.
- It is often hereditary and tends to run in families.
Secondary glaucoma
- It is caused as complications of other medical conditions and/or procedures, including eye surgery, advanced cataracts, eye injuries, certain eye tumors, and uveitis.
- It can be caused by drugs such as corticosteroids, which are used to treat eye inflammations.
- Pigmentary glaucoma is caused when pigment from the iris breaks off, thereby slowing the fluid drainage and blocking the meshwork.
- Neovascular glaucoma is a severe form of secondary glaucoma that is linked to diabetes.
Drugs causing glaucoma
Common drugs causing glaucoma include:
- Difluprednate
- Dexamethasone
- Hydrochlorothiazide
- Medrysone
- Prednisolone
- Prednisone
- Rimexolone
- Scopolamine
- Umeclidinium
