Purpose
Bilateral macular coloboma is an extreme rare congenital malformation. Compared to the typical nasoinferior coloboma of the retina and choroidea which results from the deficient closure of the embryonal fissure, macular coloboma is localized on the central fundus. This congenital defect is associated with visual impairment and nystagmus. Macular coloboma should be differentiated from post-inflammatory retinal/choroidal scars.
Case report
We report the case of an 18-year-old patient who was referred to Department of Ophthalmology at University of Leipzig. Patient has an amblyopia, myopia and nystagmus of both eyes. The visual acuity was hand motion on his right eye and 1/10 on his left eye. The fundus examination showed macular coloboma of both eyes and retinal detachment in the area of coloboma without tractional component. The sister of the patient showed a more mild degree of macular coloboma and suffered from low vision and nystagmus too. In the follow-up of 3 years no progression of retinal detachment was observed, and therefore no surgical intervention was performed.
Conclusions
Bilateral macular coloboma is a rare congenital defect. Because of the family history, genetical components must be considered. If the retinal situation is been stable, non surgical treatment is required.
