Glaucoma is a common eye disease and is also known as high eye pressure. Insufficient drainage of the aquous humor ( intraocular fluid) causes the intraocular pressure to rise. The normal range of intraocular pressure is 10-21 mmHg and can vary during the day. Glaucoma does not have a symptom and diagnosed in routine eye examinations. It causes loss of vision in untreated patients. High intraocular pressure causes damaging of the optic nerve and results in visual field defects. Glaucoma is the leading blinding disease in the world. The incidence is 2% in people over 40, it can be seen in newborns. The common result of this multivarietive disease is permanent vision loss. It can be divided into 2 forms:
1- Chronic open angle glaucoma
2- Angle closure glaucoma
Ageing, family history, history of cortizone medication for a long time, diabetes, migraine, myopia and eye traumas increase the risk of glaucoma.
Hence there are no symptoms glaucoma can only be asessed by an intraocular pressure measurement, visual field and retinal nerve fiber analysis and corneal thickness measurement.
First round treatment is the pressure lowering eye drops, if this fails then laser or surgery will be performed. UCOMA
