1) Open Angle Glaucoma.
This is the most common form of glaucoma in Western populations and is caused by the trabecular meshwork becoming silted up.

2) Chronic Closed Angle Glaucoma.
This is caused by blocked drainage through a narrow angle between the iris and the cornea with resultant scarring of the trabecular meshwork. It is more common in Asian and Chinese populations.

    Intraocular pressure (IOP) is a major risk factor for Glaucoma – new technologies, such as Diaton tonometer, have been developed to measure intraocular pressure over the eyelid without use of anesthesia drops. The measurement with Diaton tonometer is done over the upper eyelid and over the sclera, above the cornea – therefore corneal parameters, such as thickness, corneal rigidity..etc., do not effect Diaton IOP readings.
