Retinoschisis and neurosensory detachment in advanced focal glaucoma

A 71-year-old woman with normotensive primary open-angle glaucoma presented with an asymptomatic temporal peripapillary retinoschisis, associated with serous retinal detachment in the eye with the more advanced glaucoma. It was located at the inferior pole of the optic disc, in the proximity of a glaucomatous focal disc defect.

Although congenital optic pits are strongly related with juxta-papillary retinoschisis, retinoschisis can also arise from acquired defects in the proximity of glaucomatous optic discs. As symptoms depend on the extent of the retinoschisis, the prevalence of this complication could be greater than that reported in glaucomatous eyes.
