Multimodal Image Analysis in Acquired Vitelliform Lesions and Adult-Onset Foveomacular Vitelliform Dystrophy

Table 2

Summary of visual acuity and OCT findings. Results are expressed as follows: median, 25th–75th percentiles and ^†absolute number, %. AVL, acquired vitelliform lesions; AOFVD, adult-onset foveomacular vitelliform dystrophy; VA, visual acuity; LH, lesion height; GLD, greatest linear dimension; IS/OS, inner segment/outer segment; ELM, external limiting membrane.
