Objective
To demonstrate the cross-sectional anatomy in crystalline retinopathy.
Methods
A 24-year-old woman with bilaterally decreased vision and nyctalopia was examined by optical coherence tomography (OCT).
Results
Visual acuity was 20/40 OD and 20/60 OS. Fundus examination demonstrated numerous reflective, yellow-white crystalline deposits scattered throughout the posterior pole and midperipheral retina. OCT disclosed an abnormal high reflectivity in red to orange colors throughout the entire neuroretina, retinal pigment epithelium (RPE) and choroid. The RPE-choriocapillaris-complex was thickened and hyperreflective corresponding with dense crystalline deposits.
Conclusions
The uncommon hyperreflectivity relates to the deposition of numerous infiltrates. In-vivo investigations by OCT confirmed histological studies that a crystalline retinopathy corresponds with numerous infiltrates in the retina, RPE and choroid. The RPE and choroid have an intensive hyperreflection and may be the primarily location of the disease.
