Purpose: To report a case of retinoschisis and dialysis associated with bilateral posterior microphthalmos and papillomacular fold.
Design: Observational case series.
Methods: Complete ophthalmologic examination of three of five siblings presenting with bilateral posterior microphthalmos and papillomacular fold. Optical coherence tomography (OCT) data are presented to confirm the abnormal anatomy.
Results: All subjects have bilateral elevated horizontal papillomacular retinal fold with cystoid macular edema and shallow subretinal fluid. Optical coherence tomography was consistent with our examinations. One subject, a 13-year-old Hispanic, initially presented with retinoschisis in the superotemporal quadrant of the left retina that developed 9 years later into a retinal dialysis without subretinal fluid. The right eye of this same patient developed retinoschisis in the far superotemporal retinal periphery during 9 years of observation.
Conclusion: Retinoschisis and dialysis may occur in patients with posterior microphthalmos with papillomacular fold. Optical coherence tomography may be helpful in assessing these patients.
