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 i f not promptly treated => permanent vision loss

4 SYMPTOMS f loaters - bits of debris in field of vision that look like spots, hairs or strings

5

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

7 C an 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

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

9 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

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

11 PHOTOCOAGULATION

12 CRYOPEXY

13 PNEUMATIC RETINOPEXY

14

15 SCLERAL BUCKLING

16 VITRECTOMY

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

18 Retinal detachment can occur as a result of; Obesity Trauma Nearsightedness

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

20 detachment/DS detachment/DS overview 01-overview
