“…A series of 345 surgically treated OphAs reiterates this, as microsurgical clipping was found to have higher odds of visual morbidity (OR 8.5, 95% CI 1.1–64.9, p = 0.04) although lower odds of residual and re-treatment (OR 0.06, 95% CI 0.01–0.28, p < 0.001; OR 0.12, 95% CI 0.02–0.58, p = 0.008, respectively) when compared to endovascular therapies ( 27 ). Importantly, the definitive nature of surgical clipping may be exaggerated in observational studies, and the non-curative treatment rate, in fact, likely approaches 12% ( 28 ).…”
