Atypical minimal peripapillary choroidal colobomata.

Many reports of colobomata of the choroid, involving the peripheral choroid, are available in the literature, but no case of a localized congenital choroidal defect in the peripapillary region has bcen reported. A case of such colobomata present on both sides is reported here which, since coming under observation I0 years ago, has presented a considerable diagnostic problem to different ophthalmologists. This is because the colobomata in this case are associated with oedema of the optic disc on both sides and a serous type of retinal detachment involving the macular region and extending on up to the disc margin on one side.
