Congenital Optic Pit and Argon Laser Photocoagulation

Congenital Optic Pit of the papilla (CPP) is a monolateral little hole located in the inferior temporal portion of the optic nerve CPP is characterized by a spherical shape involving 1/3 of the optic nerve surface and has a deep face with pigmented base The most important complication is retinal detachment, in particular macular detachment. The origin of subretinal fluid is unknown. We observed 2 cases, both females, 18 and 25 years old, one complicated by macular detachment. We treated macular detachment with argon laser photocoagulation applying spots around the detached retina and achieved improvement of visual acuity. Most important diagnostic feature in CPP seems to be retinal angiography, demonstrating hyperfluorescence of CPP and macular detachment.
