A 63-year-old healthy woman presented with a 2-week history of metamorphopsia in the left eye. Her ocular history was notable for high myopia and mixed-mechanism glaucoma. She had been treated with bilateral laser iridotomies. She had a history of laser-assisted in situ keratomileusis (LASIK) done in both eyes. Her eye medications included xalatan and azopt. Her systemic medications included fluoxetine and multivitamins. The visual acuity was 20/20 in both eyes. The anterior segment examination showed laser-assisted in situ keratomileusis flaps, patent iridotomies, and 2+ nuclear sclerosis bilaterally. Dilated fundus examination showed tilted, saucerized disks with advanced temporal rim thinning bilaterally. No optic pits were seen.. In the left eye, the retina appeared elevated in the papillomacular bundle (Figure 1). Fluorescein angiography showed late hyperfluorescence on the temporal optic nerve (Figure 2). Optical coherence tomography (OCT) showed retinoschisis extending from the disk to the perifoveal region (Figure 3). No optic pit was detected. B-scan showed a normal choroid. Patient returned for follow-up 6 weeks later with decreased vision in the left eye. Visual acuity worsened to 20/70 in the left eye. Optical coherence tomography showed extension of the retinoschisis through the fovea (Figure 4).
