  1. GLAUCOMA

  2. Sufficient rise in intraocular pressure to cause visual damage

  3. Classification • Congenital Glaucoma • Primary Glaucoma • 1- Open angle • 2- closed angle • Secondary Glaucoma • Absolute Glaucoma

  4. Congenital • Features • Buphthalmos corneal diameter 12 mm < 1 yr • Tears of descemet’s membrane • Corneal haze • Increased A/C depth • Optic disc cupping

  5. Primary Glaucoma • Primary open angle glaucoma • Features Virtually symptom less frequent change of glasses gross field defect (late stages) • Diagnosis Ophthalmic exam Field test

  6. Optic Nerve

  7. Field Test

  8. Humphery Field Trace

  9. Normal Disc

  10. Cupped Disc

  11. Primary Glaucoma's • Angle closure • Acute • Very painful • Reduced vision • Nausea vomiting • Can be triggered by dilating drops

  12. Acute Glaucoma

  13. Secondary Glaucomas • Lens • Intumescence • Dislocation • Phacolytic • Trauma • Uveitis • Neovascular

  14. Absolute Glaucoma • Blind • Painful • Treatment • Enucleation • Laser/Cryotherapy • Absolute alcohol

  15. Treatment

  16. Treatment • Medical • Beta blockers (Timolol) • Carbonic anhydraze inhibitors Azopt and Trusopt • Sympathomimetics Propine and Apraclonidine • Parasympathomimetics (pilocarpine) • Prostaglandin Derivatives (Xalatan)

  17. Treatment • Laser • Trabeculoplasty • Sclerostomy • Cycloablation

  18. Treatment • Surgical • Goniotomy congenital • Trabeculotomy for congenital glaucoma's • Trabeculectomy for adult glaucoma's • Implants for difficult non responsive
