Serous macular detachment due to optic disc pit and treatment alternatives

Abstract

To review the causes of serous macular detachment due to congenital optic disc pit and the efficacy of the treatment. A 47 year-old woman complained of diminution of vision in her left eye in one week. On examination, best corrected visual acuity in the left eye was 0.7 with a refractive correction of +2.0 diopters. Fundus examination revealed the presence of an optic disc pit in the temporal part of the disc. There was an associated serous detachment of the posterior pole about 4 disc-diameter in size. The right eye was evaluated as normal. One month later, visual acuity decreased to 0.2. The patient was treated with argon laser photocoagulation (ALP) applying two rows of argon green laser burns along the temporal margin of the disc. Six weeks later, the patient stated subjective improvement of vision and visual acuity increased to 0.7. The detached area was flattened. Fluorescent angiography revealed staining of the disc pit but no hyperfluorescence over the posterior pole. Serous macular detachment may occur due to optic disc pits. Many treatment methods were tried in the treatment of serous macular detachment and argon laser photocoagulation applied to the temporal side of the optic disc, is the most common method, reported. In conclusion, we also think that since ALP is an easy method which does not cause major important complications, it may be tried in the treatment of patients with serous macular detachments due to optic disc pit.
