Contractility of optic disc coloboma is rare. We report herein the case of a woman with a contractile optic coloboma.
Report of a Case.
—A 41-year-old woman presented with poor visual acuity in her right eye since birth. She was otherwise healthy.The best corrected visual acuity was 20/300 OD and 20/20 OS. The right eye showed a +1 relative afferent pupillary defect. The anterior segment was normal bilaterally. Fundus examination revealed an anomalous right optic disc (Figure), which appeared enlarged and deeply excavated centrally. The optic disc was also continuous with a colobomatous defect that extended inferotemporally (Figure). The neural rim appeared thin. There was glial tissue in the center of the disc. The retinal vessels emanated from the disc in an anomalous pattern. No retinal detachment was present. Superotemporal to the disc was a sectoral area of bone-spicule pigmentation distal to an attenuated retinal venule.During fundus
