  1. RETINAL DETACHMENT Marina Capak Mentor: A. Žmegač Horvat

  2. RETINA • light-sensitive layer of tissue • sends visual messages through the optic nerve

  3. pulled away from the underlying choroid • small areas of the retina torn => retinal tears or retinal breaks • retinal cells deprived of oxygen • if not promptly treated =>permanent vision loss

  4. SYMPTOMS • floaters- bits of debris in field of vision that look like spots, hairs or strings

  5. SYMPTOMS • floaters • light flashes • shadow or curtain over a portion of visual field • blur in vision

  6. Can occur as a result of: • trauma • advanced diabetes • an inflammatory disorder, such as sarcoidosis • shrinkage of the jelly-like vitreous that fills the inside of the eye

  7. vitreous liquid leaks through retinal tear and accumulates underneath retina • retina can peel away from underlying layer of blood vessels

  8. Factors that may increase risk of retinal detachment: • aging - more common in people older than 40 • previous retinal detachment in one eye • family history of retinal detachment • extreme nearsightedness • previous eye surgery • previous severe eye injury or trauma

  9. TREATMENTS Retinal tears: • laser surgery (photocoagulation) • freezing (cryopexy) Retinal detachment: • pneumatic retinopexy • scleral buckling • vitrectomy

  10. PHOTOCOAGULATION

  11. CRYOPEXY

  12. PNEUMATIC RETINOPEXY

  13. PNEUMATIC RETINOPEXY

  14. SCLERAL BUCKLING

  15. VITRECTOMY

  16. When a surgeon injects a bubble of expandable gas into the vitreous cavity it is called: • scleral buckling • vitrectomy • pneumatic retinopexy • photocoagulation • cryopexy

  17. Retinal detachment can occur as a result of; • Obesity • Trauma • Nearsightedness

  18. When a surgeon uses intense cold to freeze the retina around the retinal tear it is called; • Scleral buckling • Vitrectomy • Pneumatic retinopexy • Photocoagulation • Cryopexy
