Association between cilioretinal arteries and juxtapapillary scars.
We examined the relationship of cilioretinal arteries (CRAs) to juxtapapillary chorioretinal scars, along with the developmental significance of the latter in relation to CRA formation. Both eyes of 360 patients were studied. Sixty-eight (18.9%) of these patients had a CRA in at least one eye, 13 of these 68 (19.1%) had one in both. The CRAs were distributed equally between right and left eyes. Two hundred eight patients (57.8%) had a scar in at least one eye; 157 of these (75.5%) had one in both. The presence of a CRA was significantly associated with the presence of a scar. Since both are common developmental variations, this correlation points to a common embryologic formation mechanism.
