    Abstract:
    PURPOSE: To describe multimodal imaging of two cases of bilateral non-vascularized pigment epithelial detachments (PED) in young patients with a long-term follow-up. METHODS: A complete ophthalmological examination was performed at each follow-up visit including best corrected visual acuity (BCVA), intraocular pressure, slit lamp examination, spectral domain optical coherence tomography (SD-OCT), fluorescein and indocyanine green angiography, OCT angiography. RESULTS: Multimodal imaging of two women presenting avascular PED, aged 43 and 57, respectively, was described. In both patients, SD-OCT revealed a high central macular hyporeflective elevation corresponding with PED. Both patients showed a choroidal layer thicker than 420 μm. Fluorescein and indocyanine green angiography didn't show any choroidal neovascularization either at early or late frames. Cross-sectional and en face optical coherence tomography angiography (OCTA) didn't show any flow beneath the PED. During the follow up period one eye showed a retinal pigment epithelium tear and all eyes showed the presence of apical sub-retinal fluid and hyperreflective material on the top of the PED. None of the two patients showed any sign of atrophy during the follow-up period. CONCLUSION: The peculiar characteristics of the presented cases suggest that specific pathogenetic mechanisms, not necessarily related to age related macular degeneration, may play a key role in the development of these lesions. Whether early onset of such drusenoid PED is a specific entity resulting from a genetic deficit of lipid transporters in the RPE is unknown. Further genetic and metabolic studies should be conducted.
