DESCRIBING THE LOCATION AND MORPHOLOGY OF THE DOTS IN WHITE DOT FOVEA USING ADAPTIVE OPTICS.
Purpose: To characterize the white dots in white dot fovea, an entity chiefly described in Japan, using adaptive optics imaging and propose a hypothesis regarding their origin.
Method: The patient underwent comprehensive ophthalmic examination, including color and green monochromatic fundus photography, fluorescein angiography, spectral-domain optical coherence tomography, and adaptive optics imaging.
Results: An asymptomatic 66-year-old Korean woman presented with bilateral white, glistening deposits in a ring pattern around the fovea of both eyes. The dots were highly reflective on green monochromatic images, were not visible on fluorescein angiography, and appeared hyperreflective in the inner retina using spectral-domain optical coherence tomography. Adaptive optics showed polygonal granules ranging from 1 to 10 μ m in size. The patient denied any systemic disorder or the use of any medications related to crystalline retinopathy. The patient had lived in Japan for 35 years before just moving to the United States.
Conclusion: The location, small size, and polygonal shape of the dots in white dot fovea are suggestive of intraretinal deposition of crystals, and not cells on the surface of the fovea as has been previously proposed. Carotenoid deposition related to dietary habits is a plausible cause because of the similarity to other retinopathies associated to these compounds.
