Types of glaucoma
Glaucoma is of two main types:
Open angle glaucoma - Open angle glaucoma which is chronic in nature progresses at a much slower rate so that the patient might not be aware of the fact that they have lost their vision until the condition has advanced significantly.
Closed angle glaucoma. Closed angle glaucoma might appear without warning and can be very painful and the ensuing loss of vision might progress rapidly. However, the accompanying discomfort of the process often induces the patients to look for medical aid prior to the occurrence of permanent damage.
