RETROBULBAR TRIAMCINOLONE FOR BRANCH RETINAL VEIN OCCLUSION

In a retrospective interventional case series involving 50 consecutive patients (50 eyes), trans-Tenon’s retrobulbar triamcinolone acetonide (20 mg; TA) injection was given as initial treatment for macular oedema associated with branch retinal vein occlusion (BRVO). Foveal thickness decreased significantly at 3 months after injection (p<0.0001). Improvement in visual acuity of at least 0.20 logMAR was seen in 22 eyes (44%). After 3-month follow-up, 29 eyes (58%) needed additional TA injections or pars plana vitrectomy (PPV). PPV seemed to be effective for macular oedema resistant to TA. IOP elevation and cataract progression occurred in less than 10% of all patients. Kawaji et al conclude that trans-Tenon’s retrobulbar TA injection appears to be safe and relatively effective for macular oedema associated with BRVO. Further evaluation of the effect of PPV on macular oedema resistant to TA injection is warranted.
