Parafoveolar intraretinal crystals in pearson syndrome

To describe the occurrence of bilateral parafoveolar intraretinal crystals in a patient with Pearson syndrome (bone marrow-pancreas syndrome).

A patient with an established diagnosis of Pearson syndrome underwent complete ophthalmic examination and optical coherence tomography.

Fine, refractile, crystalline, parafoveolar intraretinal deposits were seen bilaterally. There was no evidence of pigmentary retinopathy or ophthalmoplegia.

Intraretinal crystals in the macula may be seen in Pearson syndrome and may not cause a substantial decrease in visual acuity. Pearson syndrome should be considered in the differential diagnosis of parafoveolar crystalline retinopathy.
