An optic nerve disease. An intraocular pressure reduction surgery called Trabeculectomy, in conditions where medicinal drug treatment with drops does not help and when there is eye damage resulting from the disease. Purposes of the operation are reduction in intraocular pressure and increasing fluid drainage from the eye, in order to reduce the intraocular pressure.
The procedure is performed under local anesthesia. During the procedure a pathway for draining the eye fluid is created, which drains through a small nozzle under the conjunctival tissue. The drainage orifice is covered with the eye wall tissue and is not exposed to the outside. The operation is usually performed under the upper eyelid. After the procedure, a slight swelling of the upper conjunctiva occurs due to the inflow of fluid to this area. On the day of surgery, a bandage is placed over the eye. The first observation is usually carried out on the next day after surgery. Occasionally, an Ahmed implant – drain that regulates the intraocular flow of fluid – may be used.
Glaucoma treatment is designed for patients who suffer from optic nerve degeneration, but it can be problematic due to the fact that most of the patients affected by the disease do not feel its symptoms and are generally not even aware of it. In the early stages of the disease there is no real damage to the field of vision and even minor defects in the field of vision are not noticeable at all, as they usually appear in the periphery of vision. In addition, Glaucoma disease is not characterized by pain, pressure or unusual sensations, so presence of the disease is often discovered by the ophthalmologist by chance.
Defects in optic nerve function examination, performed in the computerized field of vision test. Intraocular pressure test with an ophthalmologist at the HMO.
