Postmortem eyes from 101-year-old female. Past clinical history includes a poor vision for many years due to macular degeneration. The last visual acuity test recorded 6/15 OD and 6/6 OS. IOP 14 and 18 torr OS. Histopathology: Disclosed and yellow 2x2mm macular lesion. Microscopic examination: elevated placoid macular lesion with overlying pigment granules. Electron microscopy examination: pigment granules with abundant lipofuscin and melanolysosomes, photoreceptor cells markedly attenuated (less degenerated at the periphery) Numerous calcified drusen throughout the retina particularly in the posterior pole. RPE lipofuscin content is elevated in Best’s dystrophy. The extractability of the PRE lipofuscin fluorophores is reduced (it is normal during senescence). The defect in Best’s dystrophy accelerates this age related change in lipofuscin.

Condition/keywords: Best vitelliform macular dystrophy (BVMD), fundus photograph

Top (B-mode): The longitudinal scan reveals a hyperechoic, flat, and well-demarcated macular lesion with posterior acoustic shadowing, pathognomonic for choroidal osteoma. Bottom (A-mode): Standardized tracing shows a tall initial spike (100% reflectivity) at the tumor surface with rapid decay to acoustic silence, confirming sound absorption by calcified tissue. This pattern remains unchanged at variable gain settings.

Coupled OCT B-scan and IR imaging of a 17-year-old man with Combined hamartomas of the retina and retinal pigment epithelium (CHRRPE) at the posterior pole of the left eye. One can see a highly reflective elevated macular lesion with hyporeflective shadowing of the underlying tissue and obscuration of the normal retinal layers.
