To investigate the effects of 1% atropine eye drops on the choroidal thickness and structure of amblyopic and fellow eyes in children with hyperopic anisometropic amblyopia. This study included 16 children with hypermetropic anisometropic amblyopia. All patients received 1% atropine eye drops in both eyes twice a day for 7 days. In the subfoveal choroidal region, choroidal thickness, total choroidal area, luminal area, and stromal area were measured quantitatively using swept-source optical coherence tomography. The choroidal parameters of the amblyopic and fellow eyes were compared between the baseline and atropine conditions. There were no significant differences in all choroidal parameters of the amblyopic eye between baseline and atropine conditions. However, the subfoveal choroidal thickness in the fellow eye was significantly higher for the atropine condition than the baseline condition. This change was accompanied by a significant increase in both the luminal and stromal areas of the choroid. The median differences of subfoveal choroidal thickness between the conditions were larger for the fellow eye (6.46%) than the amblyopic eye (0.26%). The choroidal structural change induced by 1% atropine instillation was smaller for the amblyopic eye than the fellow eye in children with hyperopic anisometropic amblyopia. Mechanisms of choroidal thickness changes could be inhibited in amblyopic eyes. [J Pediatr Ophthalmol Strabismus. 2023;60(1):39-45.].
