RECURRENT OPTIC DISC PIT MACULOPATHY DUE TO VALSALVA'S MANEUVER.

PURPOSE: We report a patient with recurrent optic disc pit (ODP) maculopathy after Valsalva's maneuver and discuss its pathophysiology. We also hypothesize the role of Valsalva's maneuver in its genesis.

METHOD: Case report of one patient, male, 12 years old.

RESULTS

Serous retinal detachment may occur in association with the ODP, a developmental anomaly of the optic nerve head. Histopathologically, it consists of a dysplastic retina herniation into a pocket extending posteriorly through a defect in the lamina cribrosa into the subarachnoid space. These three different compartments-intraocular space, optic nerve head, and subarachnoid space-and the dynamic interactions among them should be understood as the key factors for the occurrence of ODP-related serous retinal detachment.

CONCLUSION

Based on the possibility that serous retinal detachment secondary to the ODP could be related to the Valsalva's maneuver, we strongly recommend that patients with ODP be advised to avoid intense physical or work activities that may increase abdominal, thoracic, and cerebral pressure and to refrain from playing wind instruments to avoid pretreatment, per treatment, and post-treatment intercurrences.
