| Popis: | Purpose We aimed to examine the changes in choroidal blood flow (CBF) and central choroidal thickness (CCT) in children with anisohypermetropic amblyopia using laser speckle flowgraphy (LSFG) and enhanced depth imaging optical coherence tomography (EDI-OCT). Observations The patients were both 6-year-old Japanese male children with complaints of worsening right visual acuity and were diagnosed with anisohypermetropic amblyopia. The decimal best-corrected visual acuities (BCVAs) in cases 1 and 2 were both 0.5. In both cases, LSFG results demonstrated CBF impairment in amblyopic eyes compared with fellow eyes. EDI-OCT results also showed that the CCTs of amblyopic eyes were greater than those of fellow eyes at the initial visit. Several months after the first visit, the decimal BCVAs in both cases had improved to 1.0 because of treatment. Further, the CBF gradually increased along with a decrease in the CCT of the amblyopic eye. The axial lengths and spherical powers of the amblyopic eyes in the two cases were not different during follow-up. Conclusions and importance We have determined the changes in CBF and CCT in two children with anisohypermetropic amblyopia for the first time. CBF impairments may be involved in the pathogenesis of anisohypermetropic amblyopia, and LSFG may be useful in examining CBF in pediatric anisohypermetropic amblyopia. |
