| description | AIM: To evaluate macular light sensitivity and fixation stability in anisometropic amblyopia by microperimetry.METHODS: In this cross-sectional study, 39 children(39 eyes with amblyopia and 39 fellow eyes)who were initially diagnosed with monocular anisometropic amblyopia between July 2020 and January 2022 and 42 patients with normal best corrected visual acuity(BCVA)but suffered from improper refraction were selected, and the right eyes were selected as control group. Microperimetry(MP-3)was used to measure the average threshold(AT)of macular light sensitivity at 10°and fixation stability [including the percentage of fixation points within 2° and 4°(P1, P2), bivariate contour ellipse area(BCEA)for 68.2%, 95.4% and 99.6% of points] in amblyopic eyes, fellow eyes and normal control group. The AT and fixation stability of amblyopic eyes, fellow eyes and normal control group were compared.RESULTS: Children with amblyopia had significantly lower AT than fellow eyes and right eyes of normal control group(all P<0.017), and there were no differences in the macular light sensitivity of both fellow eyes and normal control group(P=0.555). The P1 was significantly lower in amblyopic eyes than in fellow eyes and normal control eyes(all P<0.017), and there were no differences in P1 between fellow eyes and normal control group(P=0.887).There were no differences in P2, 68.2%BCEA, 95.4%BCEA and 99.6%BCEA in patients among the three groups(all P>0.05). Moreover, there was no correlation between BCVA and AT, P1, P2, 68.2%BCEA, 95.4%BCEA and 99.6%BCEA in amblyopic eyes, fellow eyes and normal control eyes(all P>0.05).CONCLUSION: The macular light sensitivity and fixation stability within 2° may be decreased in eyes with anisometropic amblyopia. |
