An acquired vitelliform lesion (AVL) is a retinal abnormality characterized by the accumulation of yellowish hyperfluorescent material in the subretinal space, but its impact on photoreceptor anatomy is incompletely understood. This study aimed to examine cone photoreceptor structure in eyes with AVL using multi-modal imaging including adaptive optics scanning laser ophthalmoscopy (AOSLO).
This was a retrospective study of subjects with AVL associated with age-related macular degeneration and adult-onset foveomacular vitelliform dystrophy. Subjects underwent color fundus photography (CFP), en-face infrared reflectance (IR), blue-light reflectance (BR) and autofluorescence (AF) imaging, and spectral-domain volume optical coherence tomography (SD-OCT) of the central macular. AVL was diagnosed based on the characteristic hyper-reflective subretinal material, anterior to the retinal pigment epithelium, with en face and cross-sectional OCT. Photoreceptor structure near the AVL was examined by AOSLO.
AVL was found in a total of 28 eyes of 27 subjects, aged 77.7 ± 6.5 years. All subjects were white non-Hispanic and 14 were female, with mean Snellen visual acuity of 0.25 ± 0.37 (LogMAR, Snellen equivalent:). AOSLO revealed the cone mosaic disruption with apparently decreased cell density and lost or altered (hyper or hypo) reflectivity in the AVL affected areas. (Figure)
AOSLO imaging of cone photoreceptors near AVLs indicate that photoreceptor degeneration may be associated with AVL development. Because AVL represents a high-risk marker for atrophic or neovascular events that lead to significant vision loss, in vivo characterization of photoreceptor status in areas affected by AVL is important for a better understanding of disease pathophysiology and for the development of interventional trials.
