We retrospectively reviewed the records, photographs, and fluorescein
angiograms of patients with chorioretinal folds to compare features of
unilateral and bilateral involvement. We studied 78 eyes of 54 patients and
found that 30 (56%) of these patients had unilateral folds and 24 (44%) had
bilateral folds. No significant difference was found in comparing visual
acuity, refractive error, age, or race in the unilateral vs the bilateral
cases. There were significantly more women in the bilateral group (P =
.043). The frequency of causes of unilateral cases differed from bilateral
cases, but this could not be statistically proven owing to our small sample
size. This analysis contains the largest number of chorioretinal folds
reported in the literature, and is the first attempt to compare unilateral
and bilateral cases.
