PURPOSE: The clinical characteristics of superior segmental optic nerve hypoplasia (SSOH) in youth were investigated to help establish diagnostic criteria.
METHODS: Eleven eyes of seven young patients (male/female ratio, 3/4; age, 15.1 +/- 3.4 years) who had good visual acuity and inferior visual field defects (VFDs) were evaluated. Goldmann and Humphrey perimetries and optic disc morphology were analyzed, and the patients were prospectively followed for a long period.
RESULTS: Visual field defects were wedge shaped and oriented to the blind spot, but discontinuous in mild cases. Nerve fiber layer defects (NFLDs) were consistent with the VFDs. The optic disc appearance was variable, with double ring signs in seven eyes, small discs in three eyes, and an incomplete topless disc in one eye. The mothers of none of the patients had gestational diabetes. Visual field defects did not progress during the prospective 8.3 +/- 1.3 years follow-up.
CONCLUSIONS: Characteristic VFD patterns on Goldmann perimetry and corresponding NFLDs are important in the diagnosis of SSOH, but not optic disc morphology.
