These are caused by a variety of eye conditions which ultimately result in a rise in the intraocular pressure [IOP] leading to the damage of the optic nerve. Causes of secondary glaucoma include
- Injury to the eye
- Neglected cataract
- Inflammation in the eye [Uveitis]
- Advanced diabetic eye disease
- Neovascular glaucoma
- Drug intake such as steroid medications
Diagnosis is made by detecting the presence of optic nerve damage as well as identifying the cause of the disease.
The primary objective of secondary glaucoma treatment is to treat the main reason which is causing the IOP to increase in the eyes. Your doctor may also prescribe you medications to keep the IOP within normal limits either until the eye condition causing the rise in IOP is treated or for a longer period of time if required. Sometimes glaucoma treatment in the form of a primary glaucoma surgery may benefit in some cases where medical management fails. Glaucoma surgery for conditions such as neovascular glaucoma usually have a high failure rates and hence may require the placement of shunts or implants to further lower IOP.
