Abstract

Background. Optic disc pits represent a rare congenital abnormality frequently associated with macular detachment. Several theories on the pathogenesis of the detachment have been proposed, but the issue still remains unclear. Treatment remains speculative as well; advocated treatments include eye-patching, bed rest, steroids, laser photocoagulation, pars plana vitrectomy with fluid-air exchange and optic nerve sheath decompression. Methods. The authors report on the case of an optic pit with associated macular detachment which developed an inner layer macular hole and, after an apparently insignificant skull trauma, a large macular break. The patient underwent a standard three-port pars plana vitrectomy, fluid gas-exchange, posterior scleral buckling and laser treatment. Results. Twelve months after surgery the retina was flat, posterior buckling was evident and laser treatment pigmented. Visual acuity was 20/600. Conclusions. The presence of strands of condensed vitreous strands crossing the posterior lacuna and exerting traction over the macula and optic disc, support the theory of a possible tractional role of anomalous vitreous adhesion in the pathogenesis of the detachment and macular break. Anomalous vitreous adhesion over the posterior retina could be related to the malformative genesis of the syndrome, and the anomalous persistence of the Cloquet's canal or primary vitreous could be responsible for the traction.
