Abstract PURPOSE: The optimal management approach to retinal arterial macroaneurysms (RAM) is unknown. This paper compares long-term outcomes in RAM treated with laser therapy versus observation. METHODS: This is an IRB-approved retrospective study of patients with symptomatic RAM. Charts of patients with a diagnosis of RAM causing symptomatic visual loss were reviewed. Patients with less than 6 months follow up, other confounding diagnoses, or additional therapy beyond thermal laser were excluded. Statistical analysis was done using χ(2) or Student's t test as appropriate. RESULTS: Forty-eight patients with RAM were identified and 27 were included in the study (13 treated, 14 observed). Mean visual acuity in the observation group improved from 20/120 to 20/96 (p = 0.53) compared to 20/280 to 20/54 (p = 0.0003) in the treated group. Subgroup analysis showed that visual acuity in primarily hemorrhagic lesions treated with laser therapy improved by 1.21 logMAR compared to a loss of 0.11 logMAR (p = 0.002) in those that were observed. In primarily exudative lesions, both treated and observed lesions showed an improvement of 0.32 logMAR. No patients in the treatment group had a final visual acuity below 20/200 compared to four in the observation group. CONCLUSION: Treatment with direct laser photocoagulation was associated in this study with greater improvement in visual acuity and may decrease the risk of severe visual loss especially in primarily hemorrhagic RAM lesions. Compared to observation alone. This article was published in Graefes Arch Clin Exp Ophthalmol and referenced in Journal of Clinical & Experimental Ophthalmology
