ABSTRACT

AIM: To investigate the efficacy and safety of orthokeratology combined with 0.01% atropine solution in adolescents with myopia.METHODS: A total of 100 adolescent myopic patients(100 right eyes)who received treatment at the Department of Ophthalmology, People's Hospital of Hengshui from January 2019 to January 2022 were enrolled. All patients were divided into two groups based on the patient's preferences and randomized controlled principles control group(n=50)and experimental group(n=50). Patients in the control group received orthokeratology alone, while those in the experimental group received orthokeratology in combination with 0.01% atropine solution. Treatment data for both groups were collected at 1, 3, 6, 9 and 12mo after treatment. The observed indicators included refraction, corneal curvature, axial length(AL), central corneal thickness(CCT), pupil diameter(PD), lipid layer thickness(LLT), break-up Time(BUT), root-mean-square of higher-order aberration(RMSh), subfoveal choroidal thickness(SFCT), corneal endothelial cell density(CD), and hexagonal cell ratio(HEX). The adverse reactions experienced during follow-up period were also observed and recorded.RESULTS: After 12mo of treatment, the refraction, corneal curvature, and AL in the experimental group were -2.42±0.17D, 38.89±1.18D and 25.44±0.23mm, respectively, which were significantly better than the control group(-2.56±0.19D, 40.12±1.65D and 25.54±0.19 mm, all P<0.05). The CCT of the experimental group(538±33 μm)was lower than that of the control group(545±41 μm), while the PD of the experimental group was higher than that of the control group(6.38±0.38 mm vs. 6.12±0.37 mm, P<0.05). LLT and BUT in the experimental group was 61.14±8.41 nm and 9.24±2.05s, respectively, which were significantly higher than those in the control group(56.14±7.22 nm and 7.27±1.99s, all P<0.05). RMSh in the experimental group was lower than that of the control group(0.73±0.21 μm vs. 0.85±0.12 μm, P<0.05), and SFCT in the experimental group was significantly higher than that of the control group(289±55 μm vs. 282±59 μm, P<0.05). Additionally, after 12mo of treatment, there was no significant difference in CD and HEX between the experimental group and the control group(all P>0.05). The main adverse reactions of both groups during treatment period were photophobia, anaphylaxis, conjunctivitis and keratitis, but there was no significant difference between the two groups(all P>0.05).CONCLUSION: Compared to orthokeratology alone, the combination of orthokeratology and 0.01% atropine solution effectively prevents and improves the development of adolescent myopia without increasing the incidence of adverse reactions.
