Abstract

Objective To observe accommodative fuction in amblyopic children with anisometropia, and the change of accommodative function after cured amblyopia. Methods Thirty-six amblyopic children aged 8~15 years (mean 9.45±1.86 years) with anisometropia were recruited. Twenty children were male while 16 children were female. The refraction was corrected. Positive relative accommodation (PRA) and negative relative accommodation (NRA) were examined by phoropter examination. Accommodation amplitude were measured by negative lens methods. The data were analyzed by SPSS statistics software system. Results There were significant difference between the accommodative amplitude (P <0.001) and PRA (P=0.001) of normal eyes and those of amblyopic eyes in amblyopic children with anisometropia; but no significant difference could be found for NRA (P=0.22). After the visual acuity of amblyopic eyes got normal, PRA in amblyopic eye was increasd but still lower than that of the contralateral normal eye (P=0.001); meanwhile, the NRA of amblyopic eyes had no significant difference from that of contralateral normal eye (P=0.92). Conclusions The accommodative amplitude and PRA of anisometropic amblyopic eyes is significantly decreased. After treatment, the accommodative amplitude and PRA of amblyopic eye are improved, but still lower than those of the contralateral normal eye. Key words: Hyperopia; Anisometropia; Amblyopia; Accommodative function

弱视儿童屈光参差治疗前后调节功能的初步研究

目的观察弱视儿童屈光参差的调节功能，以及弱视治愈后调节功能的变化。方法选取8~15岁弱视参差儿童36例(平均9.45±1.86岁)。其中20名是男孩，16名是女孩。折射被校正了。光镜检查正相对调节(PRA)和负相对调节(NRA)。采用负透镜法测量调节幅度。数据采用SPSS统计软件系统进行分析。结果弱视伴屈光参差儿童正常眼与弱视眼的调节振幅(P <0.001)和PRA (P=0.001)差异有统计学意义;NRA差异无统计学意义(P=0.22)。弱视眼视力恢复正常后，弱视眼的PRA有所增加，但仍低于对侧正常眼(P=0.001);弱视眼与对侧正常眼的NRA差异无统计学意义(P=0.92)。结论屈光参差性弱视的调节幅度和PRA明显降低。治疗后，弱视眼的调节振幅和PRA有所改善，但仍低于对侧正常眼。关键词:远视;屈光参差症;弱视;宽松的函数

期刊介绍： China Practical Ophthalmology was founded in May 1983. It is supervised by the National Health Commission of the People's Republic of China, sponsored by the Chinese Medical Association and China Medical University, and publicly distributed at home and abroad. It is a national-level excellent core academic journal of comprehensive ophthalmology and a series of journals of the Chinese Medical Association. China Practical Ophthalmology aims to guide and improve the theoretical level and actual clinical diagnosis and treatment ability of frontline ophthalmologists in my country. It is characterized by close integration with clinical practice, and timely publishes academic articles and scientific research results with high practical value to clinicians, so that readers can understand and use them, improve the theoretical level and diagnosis and treatment ability of ophthalmologists, help and support their innovative development, and is deeply welcomed and loved by ophthalmologists and readers.
