Medical treatment of glaucoma is nowadays able to maintain good eye pressure in most patients.
By strictly monitoring eye pressure values and the diagnostic data regarding the optic nerve (Computerised Visual Field, GDX, etc...), the patient is able to retain good visual function without resorting to surgery.
Medical treatment involves using drugs to reduce the production of aqueous humour, drugs to improve aqueous humour flow thereby increasing the permeability of the eye’s natural drainage canals, and drugs to protect the optic nerve.
Glaucoma surgery is carried out ONLY on patients who are not able to relieve increased pressure and loss of function with medication alone, for patients affected by congenital and juvenile glaucoma, for patients affected by narrow angle glaucoma.
Microsurgical techniques are used to create a new channel for the flow of aqueous humour, which is unable to filter sufficiently through the eye’s natural filter (trabecular meshwork) or to increase the endocular spaces in which the aqueous humour circulates.
Different techniques are used depending on the type of glaucoma.
