© 2016 Taylor & Francis. Our aim is to report 13 unusual cases of acquired, temporal sectoral scotomas. Such stationary “wedge” field defects have been reported previously in cases of presumed congenital nasal hypoplasia of the optic disc and as a complication of vitreoretinal surgery. To our knowledge, the literature provides no reports of similar defects occurring spontaneously. This is a descriptive clinical case series of 13 patients presenting with sub-acute monocular temporal visual field loss. All were clinically assessed and investigated with Goldmann perimetry, automated Humphrey visual fields, retinal optical coherence tomography, orbital ultrasound, and standard and multi-focal electroretinography. Cases were followed with serial perimetry for a mean of 3.9 years (range: 6 months to 10 years). Goldmann and Humphrey perimetry both demonstrated “wedge”-shaped defects extending temporally from an apex contiguous with, or lateral to, the blind spot. There was no evidence of optic disc drusen, glaucoma, disc hypoplasia, or focal retinitis. Sectoral optic disc swelling was not present in any patient at presentation. In all cases, the visual field defect remained stable. One patient developed a similar defect in the fellow eye after an interval of 5 years. Here we describe 13 cases of acquired, stationary temporal wedge scotomas, novel in the literature. Although the aetiology is uncertain, we propose damage to the nasal rim of the optic disc as a likely mechanism.
