PURPOSE: To describe four cases of topless optic disk syndrome without maternal diabetes mellitus.
METHOD: Four patients had incidentally discovered inferior visual field defects.
RESULTS: Ophthalmoscopic examinations in all four patients disclosed superiorly displaced entrances of the central retinal artery and thinning of the superior peripapillary nerve fiber layers. One patient had a superior peripapillary crescent with pallor of the superior disk. These clinical findings were consistent with a diagnosis of superior segmental optic hypoplasia, the topless disk. None of the patients had mothers who had diabetes.
CONCLUSIONS: The topless optic disk syndrome can occur in the absence of maternal diabetes mellitus.
