Glaucoma is a condition where the pressures in the eye increase, eventually causing damage to the optic nerve.
Not actually that common, but very important, which is why opticians look for it.
Its not always actually because intraocular pressure is raised, but its a mostly reliable sign. There are two types:
- Open angle glaucoma - in this version, fluid can drain fairly well inside the eye, and the progress of the disease is very slow. Often people are only diagnosed after some sight loss has occurred.
- Closed angle glaucoma - in this version, the eye cannot drain properly, and this can come on over hours, being very dangerous as it can cause sight loss within the day. Therefore anyone with sudden onset eye pain needs seeing urgently.
Clinical and Associated Features
Often there are no symptoms. This is why regular eye checks are important. However, there can be:
You can try a few drugs that reduce intraocular pressure such as latanoprost.
Next step is surgery, generally laser treatment, or normal surgery. The aim of this is again to increase drainage and reduce pressure within the eye.
