Spectral domain optical coherence tomography findings in retinal folds associated with posterior microphthalmos.

Posterior microphthalmos is a rare congenital malformation characterized by normal anterior segment dimensions with an abnormally small posterior segment resulting in high hyperopia. Reduced visual acuity in these cases is sometimes caused by the presence of papillomacular retinal folds. We report two cases of posterior microphthalmos in which the papillomacular folds could be visualized on spectral domain optical coherence tomography with sufficient detail to illustrate that only the layers of neural retina within the external limiting membrane were involved.
