[Role of vitreoretinal interface in the pathogenesis and therapy of macular disease associated with optic pits].
OBJECTIVE
Although the relationship between optic pits and macular lesions was described nearly a century ago, the pathology and pathogenesis of macular detachment remain unclear. Recent OCT studies have shown schisislike spaces in connection with the disc. None of the hypotheses of pathogenesis proposed so far could have been proven. Besides the hypothesis of exudation, the role of the vitreoretinal interface is kept in the background of discussion. We describe a case of macular detachment associated with optic pit that regained full vision after pars plana vitrectomy with laser coagulation and gas tamponade over a follow-up of 26 months. The purpose of our case report is to emphasize the role of the vitreoretinal interface in the pathogenesis of macular detachment associated with optic pits.
A 32-year-Caucasian woman developed macular detachment associated with an optic pit on her right eye. The vision deteriorated to 24/60. A standard three-port pars plana vitrectomy was performed. After creating a posterior vitreous detachment, all vitreoretinal adhesions were removed carefully. Peripapillary laser coagulation and gas tamponade with 15% C2F6-air mixture followed. For 26 months after surgery the macula has been flat. The vision is 60/60.


CONCLUSIONS
Besides the exudative component of macular detachment, the vitreoretinal interface seems to play an underestimated role in the pathogenesis of maculopathy associated with optic pits. Tractional forces could explain the delay of macular detachment in young adulthood and the frequency of treatment failure after laser coagulation and gas tamponade. Pars plana vitrectomy with complete removal of all vitreoretinal adhesions should be a suitable technique in the treatment of macular detachment associated with optic pits.
