Eye Injuries

1. Eye Injuries

2. 1-Blunt(contusion) • 2-Perforating Injury • 3-Perforating Injury & retained foreign body • 4-Chemicals ( acid – alkaline ) & burns • 5-Sonar (sun rayesUltra violet Enfera red) • 6-Extraocular foreign body

3. Blunt Trauma • By fist ball can cause abrasion to rupture globe1- cornea ( abrasion – oedema – staining – tear )2- sclera(rupture – haemorrhage ) • 3- iris & ciliarybody ( miosis – mydriasis – laceration – iridodialysis – antiflexion – retroflexion – aniridia – cyclodialysis – hyphaema ) • 4- lens ( vossius’s ring – cataract – dislocation – subluxation – tear ) • 5- vitreous ( opacities – haemorrhage – herniation – loss ) • 6- choroid (rupture – haemorrhage – detachment ) • 7- retina ( macular edema – degeneration – cyst hole – retinal tear – retinopathy ) • 8- optic nerve ( atrophy – avulsion )

4. Eversion Of Eyelid 1 Eversion Of Eyelid 2

5. Orbital and subconjunctivalhaemorrage

6. Corneal foreign body Corneal abrasion staind with furecein

7. Hyphaema Iridodialysis

8. Subluxated lens

9. Metal foreign body embedded the iris Perforating wound with prolapsed iris inferiorly

10. Perforating Injury • Aim of treatment : i. To save vision ii. To prevent sympathetic ophthalmitis • Signs : 1. drop of VA 2. Hypotony 3. Shallow AC – hage 4. change of pupil 5. conj edema ( chemosis ) 6. subconjhage 7. iris hole 8. wound track in corneal , lens & vitreous

11. Perforating Injury with retained foreign body • ( iron – steel – stone – glass – lead pellet – wood spicules ) • Effects : 1. mechanical 2. infection 3. chemical action ( inert metal – little reaction – suppuration ) 4. degenerative changes (siderosis - chalcosis )

12. Choroidal tears and haemorrhage Solar macular burn
