Can trauma to the eye cause Branch Retinal Vascular Occlusion?

Brief Answer: Trauma is rare cause for branch retinal vein occlu Detailed Answer: Hello Welcome to Health care magic Iam Dr. Dadapeer K,an Ophthalmologist and I answer health problems related to eye. I reviewed the history given by you. It seems from the history that he has sustained a injury while driving a heavy duty excavator.He had a corneal abrasion in his right eye and blunt injury to left eye for which he was treated. Branch retinal vein occlusion is a disease characterized by occlusion of the branch of a retinal vein and the cause is because of compression by a thickened or arteriososclerotic artery. Rarely trauma can cause branch retinal vein occlusion, however central retinal vein occlusion is more common following trauma. This can be secondary to compression by retrobulbar hemorrhage occurring as a result of trauma or because of damage to optic nerve. The common causes for branch retinal vein occlusion are compression by a arteriosclerotic artery and the common predisposing factors are diabetes, hyperlipidemia, hypertension, bleeding and clotting disorders... The treatment is by control of the associated predisposing factors and complications which can lead to loss of vision like macular edema by using intravitreal injections of steroids or by laser treatment. Later few cases of branch retinal vein occlusiion can lead to development of secondary glaucoma called as neovascular glaucoma which causes painful red eye. Hence I request you to give me details like vision in the affected eye, fundus photograph of the eye if available and treatment he is on, so that I can advice you more accurately. Thank you

Follow-up: Can trauma to the eye cause Branch Retinal Vascular Occlusion? 40 minutes later
The left eye symptoms after being hit with a small rock were initially minimal with some pain and only started to be treated 9 months later with eye drops. But the symptoms gradually got worse and 2 years later 2 Othalmologists diagnosed my friend with Brach Retinal Vascular Occlusion with hemorrhages extending down to his macula (not interfering with his central retinal function) Also, he was observed to have orbital asymmetry with the left orbit and globe being higher than the right. Could that rock have caused that problem- even extending to latent central retinal vascular occlusion? 7 years later he became blind in the left eye. Also, assuming he just happened to develop the above eye disease- perhaps 9 months after a rock hit his left eye, could the constant strain from driving an excavator for 12 years seriously exacerbated that eye disease?

Brief Answer: Loss of vision is because of secondary glaucoma. Detailed Answer: Hello Thank you for the follow up. It seems from the history that your friend was diagnosed as to be having Branch retinal vein occlusion for which he has taken treatment and because of failure of treatment he has gone blind in the eye. The chances are that the rock hitting the eye leading to branch retinal vein occlusion are very minimal but still it has a outside chance as a rare cause. The constant strain from driving excavator does not have any relation with the eye disease. Probably because of branch retinal vein occlusion either secondary to injury or because of some other predisposing factors which has resulted in secondary neovascular glaucoma which has to led painful loss of vision is the sequence of events in your friends case. The orbital asymmetry is because of change in the size of the globe because of glaucoma. Hence I can conclude by saying he his having loss of vision because of secondary neovascular glaucoma which has developed as a complication of branch retinal vein occlusion. The underlying cause for branch retinal vein occlusion cannot be pinpointed but trauma can be cause but the chances of developing branch retinal vein occlusion following trauma are rare. Hope I have answered your questions and the information is helpful to you. Thank you
