    1. R.D. BY: MARWAN ABOUAMMOH

    2. R.D. Rhegmatogenous Tractional Exudative 1/10000 In aphakics: 1-3% Rhegmatogenous R.D. has 5% chance of forming PVR

    3. R.R.D. Vitreous liquifaction R. break Eye’s movement PVD, V-R traction PVD Loss of hyaluronic acid 15% of acute PVD have a retinal tear 13-19% have vit. He PVD+hge= 70% with tears PVD+no hge= 2-4% with tears Weiss ring

    4. Acute PVD: Examine preiphery Vit hge = rest, patching ou, examine later U/S

    5. R.D. Risk factors Lattice & other peripheral degen.: 8% of pop. A cause of RD in 20-30% In RD with L.D.: 30-45% atrophic holes 55-70% tear at the edge of L.D. Dentate process, oral bay, pars plana island peripheral, cystoid degen., Paving stone degen.,

    6. 2. High myopia: >6D 3. Cataract surgery: More with PVD, ICCE>ECCE, Increased risk with P.C.otomy (1.3%), and vit. Loss 50% of R.D.’s in 1st yr.

    7. 4. Glaucoma > In pigment dispersion syndrome COAG > in R.D. patients(7% vs. 1%) Miotics & R.D. 5. R.D. in the fellow eye or FHx of R.D. 6. Trauma: retinal dialysis, giant tear

    8. Symptoms: Exam: don’t forget indentation 40-50% of all R.R.D. have > 1 break usually located 90 degrees from primary break. Types of breaks: Horse-shoe tear Operculated hole Atrophic hole Dialysis

    12. PVR A B C 1-12 TYPE

    13. ERD: Idiopathic Coats disease Central serous chorioretinopathy Uveal effusion syndrome Inflammatory Vogt-Koyanagi-Harada syndrome Syphilis Scleritis Sympathetic ophthalmia Other vasculitic entities (eg, rheumatoid arthritis, Wegener granulomatosis) Other uveitic conditions (eg, toxoplasmosis, cytomegalovirus [CMV] retinitis) Dengue fever Orbital pseudotumor Lymphomatoid granulomatosis Congenital Nanophthalmos Colobomas of the optic nerve Familial exudative vitreoretinopathy Neoplastic Choroidal melanoma Choroidal metastases Choroidal nevus Choroidal hemangioma Retinoblastoma Primary intraocular lymphoma Iatrogenic Excessive panphotocoagulation Scleral buckling Vascular factors Eclampsia Exudative age-related macular degeneration Chronic renal failure Hypertension
