目的：评估远视儿童使用1%阿托品凝胶1周后脉络膜厚度(choroidal thickness,CT)的变化。方法：选择42例4~7岁的远视儿童，予每天使用1%阿托品凝胶两次，持续7d。使用光学相干断层成像扫描测量视网膜及CT，并分析使用1%阿托品凝胶前后中心凹以及距中心凹处间隔1.0 mm的上、下、鼻和颞侧(最多3.0mm)CT的变化。结果：在远视儿童中，基线CT随位置而变化(F=27.08, P<0.05)，与中心凹相比，鼻侧及距中心凹上方2 mm、3 mm及距中心凹颞侧3 mm处的CT较薄(P<0.05)。使用1%阿托品凝胶后，中央凹及旁中心凹CT改变比较差异无统计学意义(P＞0.05)。使用1%阿托品凝胶前后视网膜厚度无明显变化(P＞0.05)。结论：短期使用1%阿托品凝胶并没有改变远视儿童的脉络膜和视网膜厚度。

Objective: To assess changes of choroidal thickness (CT) in hyperopia children after 1 week using of 1% atropine.Methods: A total of 42 hyperopia children aged 4–7 years were included into the study.A single drop of 1% atropinegel was used twice a daily for 7 days in the subjects.The thickness of retina and choroid was measured by OCT, and the changes before and after using 1% atropine gel were analyzed at the subfovea and at 1.0 mm intervals (up to3.0 mm) from the fovea at superior, inferior, nasal, and temporal locations. Results: In the hyperopia children, baselineCT parameters were varied with the location(F=27.08,P<0.05).Compared with the fovea, the CT at the nasal side,2 mm and 3 mm above the fovea and 3 mm from the temporal side of the fovea were thinner (P<0.05).After using 1%atropine gel, there was no significant difference in the CT changes of subfoveal choroidal thickness and other sites ofparafovea (P> 0.05). There was no significant change in retinal thickness before and after using 1% atropine gel (P > 0.05).Conclusion: No changes were found in the thickness of choroid and retina in hyperopia children after short-term use of1% atropine gel.
