Blunt Trauma By fist ball can cause abrasion to rupture globe
1- cornea ( abrasion – oedema – staining – tear )
2- sclera (rupture – haemorrhage )
3- iris & ciliary body ( 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 )

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. subconj hage 7. iris hole 8. wound track in corneal , lens & vitreous

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 )
