The incidence of superior segmental optic hypoplasia in young adults

In recent years, superior segmental optic hypoplasia (SSOH) is one of the diseases that have been increasingly observed. It has been reported that some cases of SSOH have been erroneously diagnosed as normal-tension glaucoma. The purpose of this report was to reinvestigate the incidence of SSOH in subjects who were approximately twenty years of age when first examined. As the first step in this study, 193 volunteers, ranging in age from 18 to 25 years, were screened by Goldmann perimetry. In order to make a diagnosis, the suspected cases were then examined by fundus examinations, which included the use of optical coherence tomography. The resulting incidence of SSOH was 2.6%, which was much higher than was previously reported in one other study (0.3%). This finding suggests that it is necessary to distinguish SSOH from normal-tension glaucoma. LA: Japanese
