Abstract
During the period 1970-87 we evaluated the changes of the optic disc, peripapillary area, detached macula and visual acuity in 16 cases with congenital pit of the optic nerve and macular detachment. The study revealed in 9 of the 16 cases (56%) an increase of the dimension of the pit or changes in its color, findings which were directly related to the duration of the macular detachment. Chorioretinal scarring, pigment migration, or both, were also noted mainly at the temporal margin of optic disc. In 5/16 cases we found during the follow-up an extension of macular elevation. In altogether 10 out of 16 cases the retinal elevation covered the larger portion of the mid-periphery temporally. In 7/16 cases the final visual acuity remained unchanged, in 9/16 cases deteriorated. The difference, however, in the latter 9 cases between initial and final visual acuity was negligible. During the follow-up period deterioration of the visual fields was also noted.
