Abstract
Key Words: (management- central retinal vein occlusion)
Central retinal vein occlusion is the second most common form of retinal vascular uiscasc next to uiabctic retinopathy and constitutes an emergent condition that may result in permanent visual impairment.
It's of two types (ischemic and non-ischemic) and progression from the non
ischemic to ischemic type may occur in about 9.4%-12.8% of cases.
Different modalities of treatment have been described but still there is no general agreement regarding a therapeutic approach. As regards medical treatment, it includes anticoagulants, isovolemic haemodilution and fibrinolytic therapy using streptokinase or recombinant tissue plasminogen activator.
Retinal photocoagulation whether PRP for treatment of complicating neovascularization occurring in the ischemic type or grid pattern for treatment of macular oedema has also been used.
Surgical trezunent ofCRYO constitutes the recent modality of treatment and it includes:
• Creation ofchor:ordinal venous anastomosis whether laser-induced for non- ischemic CR \"0 or surgically-induceu lor the ischemic l•orm.
• Transecting the ::osterior scleral ring.
• Optic nerve she21h Jecotnpression.
• Cannulation of central retinal vein.
• Yitrectomy for :;;acular oedema complicating CRVO.
