Abstract
Patients with long axial length (AL) eyes (> 25 mm) are at increased risk of globe perforation during performance of intraconal (retrobulbar) eye block. These patients often require glasses or contact lenses for myopia (nearsightedness) as children or young adults. A history of early correction for myopia might, therefore, be a predictor of long AL eyes. One hundred one patients undergoing cataract surgery had AL measured and answered questions about their use of corrective lenses. We found that a history of correction for myopia as a child or young adult was 82% sensitive and 84% specific for having a measured AL > or = 25 mm. Patients with this history may be at increased risk for globe perforation during intraconal block.
