LOCALIZATION OF MACULAR CRYSTALS ASSOCIATED WITH CHRONIC RETINAL DETACHMENT TO THE POSTERIOR HYALOID USING SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY.

PURPOSE To present a case of crystalline retinopathy associated with chronic retinal detachment and localize the macular crystals using spectral domain optical coherence tomography. METHODS Case Report. RESULTS A 37-year-old man with previously treated chronic retinal detachment presented with normal vision and crystalline maculopathy. Spectral domain optical coherence tomography localized the macular crystals to the posterior hyaloid membrane and on the internal limiting membrane, but not within the retina. CONCLUSION The macular crystals in crystalline retinopathy associated with chronic retinal detachment most likely originate in the subretinal space beneath the detached retina, migrate through the retinal break into the vitreous cavity, and lodge on the surface of the internal limiting membrane. When the posterior hyaloid membrane separates, the crystals, which are attached to the posterior hyaloid membrane, elevate from the retina.
