Emergency Department Care
The cornerstone of emergency department (ED) treatment for retinal vein occlusion may rest with the awareness of the disease entity by the ED physician. When considered in the proper clinical scenario, expeditious consultation by an ophthalmologist in the ED, can enable definitive diagnosis and so that appropriate intervention and follow-up care is ensured.
Treatment remains controversial at the present time. The Canadian Journal of Ophthalmology 2008 noted "No intervention has emerged as the standard of care. Current management in most centers is close observation for complications and treatment as they arise."[5] Another 2008 study notes that many different interventions have been advocated, but evidence is lacking as to their merit. Several randomized clinical trials are underway at the present time.[6]
Current literature and practice for the treatment of CRVO remains controversial. Vitreous Retina Macula Consultants of New York, a large and well-established retina practice group in New York City, advocates laser photocoagulation for managing rubeosis irides.[7] For the treatment of macular edema, they promote intraocular triamcinolone or bevacizumab (Avastin) in CRVO. In a small prospective, multicenter randomized, double-masked, placebo-controlled trial, intraocular injection of ranibizumab (0.5 mg) resulted in rapid improvement in 6-month visual acuity and macular edema, with low rates of ocular or nonocular safety events. Improvement required repeated injections. Further long-term study and follow up is needed.[8]
In one pilot study, simultaneous intravitreal injection of triamcinolone/tPA effectively reduced macular edema and improved the best corrected visual acuity (BCVA) in patients with CRVO without serious complications, although repeated treatments were required in 75%.[9]
Dalteparin was found superior to aspirin in improving visual acuity and preventing neovascularization in CRVO in a 2008 study.[10] Radial optic neurotomy (RON) has shown good results in improving visual loss in severe CRVO in a limited 2008 study.[5] Of note, a single case study in 2008 noted the use of hyperbaric oxygen, and subsequent visual improvement in a patient who refused other intervention.[11]
Current literature and practice for the treatment of BRVO is controversial as well. Vitreous Retina Macula Consultants of New York note that there is "no known medical treatment" for branch retinal vein occlusion.[7] A small study in 2008 noted intravitreal triamcinolone and grid laser photocoagulation effective in the treatment of BRVO.[12] In another 2008 study, triamcinolone acetonide retrobulbar injection was found effective for BRVO.[13] Pars plana vitrectomy was effective when the macular edema was resistant to improvement with triamcinolone alone.
