Purpose: To correlate the clinical and histopathologic features of Best vitelliform macular dystrophy (BVMD).
Methods: Two eyes were obtained postmortem from a patient with BVMD. The patient's clinical information was reviewed. Series sections of the globes were performed and sequentially stained with hematoxylin-eosin, periodic acid-Schiff or Masson trichrome. A section of the left macula was submitted for electron microscopic processing. Histopathologic findings were reconstructed in a scaled two-dimensional map and compared with fundus photography, fundus autofluorescence (FAF), fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) images.
Results: The macular lesion of the right eye was identified as a well-demarcated region with pigment, elevated submacular yellow material and subretinal fluid. This corresponded histopathologically to a well-circumscribed area of RPE hyperplasia, accumulation of lipofuscin in the RPE, deposition of granular material in the photoreceptors, macrophages and drusen. The left eye displayed a 1 disc diameter chorioretinal scar with surrounding shallow fluid and submacular pigment. This corresponded to RPE changes and a fibrocellular proliferation in the choriocapillaris.
Conclusion: Histopathologic mapping revealed retinal edema, RPE abnormalities, drusen and a chorioretinal scar in BVMD that correlated with the fundus, FFA, FAF and OCT findings.

In this review, we summarize the findings of several pre-clinical studies in the canine BEST1 disease model. To this end, client-owned and purpose bred dogs that were compound heterozygotes or homozygotes, respectively, for two or one of 3 different mutations in BEST1 were evaluated by ophthalmic examination, cSLO/sdOCT imaging, and retinal immunohistochemistry to characterize the clinical and microanatomic features of the disease. Subsequently AAV-mediated gene therapy was done to transfer the BEST1 transgene to the RPE under control of a hVMD2 promoter.

Purpose: Best vitelliform macular dystrophy is an inherited macular dystrophy associated with over 250 pathogenic variants of the Bestrophin-1 ( BEST1 ) gene. Although several types of lesions of best vitelliform macular dystrophy are well-described, reports of phenotypic variations associated with rare genetic variants are limited.
Methods: This was a retrospective case series performed in 2021 at a tertiary eye care center.

Purpose: to report a case of exudative perifoveal vascular anomalous complex (ePVAC) in a patient with adult-onset foveomacular vitelliform dystrophy.
Observations: A 71-year-old male presented with moderate vision loss in his left eye. His past medical and ocular history were unremarkable.
