Bilateral ring scotomas following laser in situ keratomileusis

A 53-year-old white man who had a history of transient ocular hypertension had bilateral laser in situ keratomileusis (LASIK) for myopia. Subsequent computerized static perimetry revealed bilateral, persistent, repeatable midperipheral ring scotomas. The pre-LASIK visual fields were within normal limits, and the optic discs appeared stable and not diagnostic for glaucomatous optic neuropathy. A comprehensive baseline data set before laser refractive surgery aids subsequent assessment of individuals at high risk for developing glaucoma.
