The term glaucoma refers to a group of diseases that have in common a characteristic optic neuropathy with associated visual field loss. Although the elvated intraocular pressure is one of the primary risk factors, its presence or absence does not have a role in the definition of the disease.
"Glaucoma can result in vision loss and blindness. However, with early detection and treatment, you can often protect your eyes against serious vision loss"
Early detection and treatment is essencial to control the disease and preserve remaining vision.
Glaucoma is the second leading cause of blindness worldwide and the first cause of irrivisable blindness.
Glaucoma risk factors:
* Increased Intraocular Pressure.
* Age over 45 years.
* Family history of glaucoma.
* Black racial ancestry.
* Decreased central corneal thickness (CCT).
* Nearsightedness (high myopia).
* Previous injury to the eye.
* Prolonged corticosteroid use(topical or systemic).
Types of glaucomas that diagnosed and
treated by the department:
(1) Primary chronic open-
(2) Chronic closed angle glaucoma.
(3) Narrow angle glaucoma.
(4) Acute closed angle glaucoma.
(5) Normal tension glaucoma.
(6) Secondary glaucoma.
(7) Congenital glaucoma.
Diagnostic tests done by the Department:
* Tonometry: Measuring of intraocular pressure by Goldman Applanation
* Ophthalmoscopy: This examination is done to check the internal part of the
eye, mainly the optic nerve head, this is done by using direct ophthalmoscope
indirect ophthalmoscope or high plus lenses (+90, +78 D lenses).
* Gonioscopy: A test to evaluate the angle of the anterior chamber, using both direct and indirect gonioscopic lenses.
* Perimetry: A special test for the visual field done by using Octopus and Humphery Perimeter.
* Pachymetry: An examination to measure the thickness of the cornea, using
* Optical Coherence Topography : A special test tp measure the thickness of the retinal nerve fiber layer and optic nerve head.
1/ Medical treatment
Different types of drugs are used for medical treatment of glaucoma, includes Beta Blockers, Prostaglandin analogues, alpha agonists and topical and systemic carbonic anhydrase inhibitors.
2/ Laser :
* Argon laser trabeculoplasty.
* Yag laser peripheral iridotomy ( P.I).
3/ Surgeries :
