ABSTRACT

Purpose: To investigate the change in ocular parameters of anisomyopic children treated with 0.01% atropine. Methods: This retrospective study analyzed the data of anisomyopic children who underwent comprehensive examination at a tertiary eye center in India. Anisomyopic subjects (difference of ?1.00 D) of age 6–12 years who were treated with 0.01% atropine or prescribed regular single vision spectacle and had follow?ups of more than 1 year were included. Results: Data from 52 subjects were included. No difference was observed in the mean rate of change of spherical equivalent (SE) of more myopic eyes between 0.01% atropine (?0.56 D; 95% confidence interval [CI]: ?0.82, ?0.30) and single vision lens wearers (?0.59 D; 95% CI: ?0.80, ?0.37; P = 0.88). Similarly, insignificant change in the mean SE of less myopic eyes was noted between the groups (0.01% atropine group, ?0.62 D; 95% CI: ?0.88, ?0.36 vs. single vision spectacle wearer group, ?0.76 D; 95% CI: ?1.00, ?0.52; P = 0.43). None of the ocular biometric parameters showed any difference between the two groups. Though anisomyopic cohort treated with 0.01% atropine revealed a significant correlation between the rate of change of mean SE and axial length in both eyes (more myopic eyes, r = ?0.58; P = 0.001 and less myopic eyes, r = ?0.82; P < 0.001) compared to single vision spectacle wearer group, the change was not significant. Conclusion: Administration of 0.01% atropine had minimal effect on reducing the rate of myopia progression in anisomyopic eyes.

ABSTRACT

AIM: To valuate the efficacy of 0.01% atropine for controlling myopia in children of different ages.METHOD: A randomized, double-blind, placebo control and single-center study was conducted. A total of 295 myopic children, aged 6~13 years, with myopia of -0.5D~-6.00D and astigmatism ≤2.0D, who admitted to our hospital from May 2019 to May 2020 were randomly assigned to experimental group(197 cases)and control group(98 cases)in a 2:1 ratio. Two groups were further divided into three subgroups according to age, 6~8 years old group(40/26 cases), 9~10 years group(84/34 cases), and 11~13 years group(73/38 cases). 0.01% atropine was administrated in the experimental group and placebo was administrated in the control group once before sleep. The changes of parameters were compared before and at 2wk, 3, 6, 9 and 12mo after treatment. Intraocular pressure, accommodation amplitude, best corrected distance and near visual acuity, pupil diameter and tear film were tested at 2wk. Cycloplegic refraction was assessed before treatment, and at 6 and 12mo after treatment.RESULTS: The spherical equivalent and axial length progression at 12mo after administration was -0.37±0.69D and 0.29±0.24mm in the experimental group, and -0.59±0.65D and 0.37±0.23mm in the control group(P=0.008, 0.006). In 6~8 years group, spherical equivalent and axial length progression between experimental and control group were not statistically significant(t=0.054, P=0.957; t=-0.623, P=0.536). In 9~10 years group, spherical equivalent and axial length progression between groups were statistically significant(t=2.056, P=0.042; t=-2.057 P=0.042). In 11~13 years group, spherical equivalent and axial length progression between groups were statistically significant(t=2.33, P=0.022; t=-2.424, P=0.017). The pupil was slightly dilated and the accommodation amplitude was decreased in experimental group, and the mean pupil diameter of the two groups was 3.94±0.79 and 3.16±0.48 mm respectively at 12mo after treatment(P<0.001). Other parameters and adverse event noted between groups were not statistically significant.CONCLUSIONS: 0.01% atropine is helpful to control the progression of myopia in children, which is well tolerated by adolescents. However, the effect of 0.01% atropine on the control of myopia for children aged 6~8 years is not enough. The findings suggest that increased concentration of atropine can be tried for 6~8 years old.

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&#x003C;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&#x003C;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&#x003C;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&#x003C;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&#x003C;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&#x003E;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&#x003E;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.

ABSTRACT

Purpose: Low?concentration atropine is an emerging therapy for myopia progression, but its efficacy remains uncertain among high myopic children. This study aimed to evaluate the efficacy and safety of low?concentration atropine eye drop (0.01%) in high myopic children. Methods: A non?randomized, parallel?group, longitudinal interventional cohort study. Myopic children were divided into two groups: (1) the intervention arm of children who received one drop of topical 0.01% atropine once a day at bedtime and (2) the control arm, in which enrolled children who were on observation only. Repeated measurements of spherical equivalent refractive errors (SERs) were performed at baseline and 1 and 2 years after treatment. Results: A total of 37 eyes were enrolled in the intervention arm (allocated to 0.01% atropine at year 1 follow?up) and 23 eyes in the control arm. After 1 year of 0.01% atropine therapy, the myopia progression was 0.15 ± 0.9 D in the intervention group versus 1.1 ± 1 D in the control group (P = 0.001). Similarly, after 2 years of treatment, the myopia progression was 0.3 ± 1.1 D in the intervention group versus 1.4 ± 1.1 D in the control group (P ? 0.001). Conclusion: Compared to no treatment, 0.01% atropine treatment had shown better effect on myopia progression in high myopic children

ABSTRACT

@#AIM:To evaluate the effects of 0.01% atropine for Asian adolescents and children of low and medium myopia in diopter and axial length. <p>METHODS:We searched on PubMed, the Cochrane Library, Embase, CNKI, CBM, VIP and WanFang Data database for randomized controlled trials(RCTs). The published languages were limited to Chinese and English. The risk bias tool provided by the Cochrane cooperation scale was used to assess the risk bias of included studies of RCTs. The published biases of included studies were assessed by the Egger's test. Meta-analysis was performed with Review Manager 5.4. <p>RESULTS: Seven randomized controlled trials with a total of 979 subjects were included(440 in the 0.01% atropine group and 539 in the control group). The Meta-analysis showed that 0.01% atropine has a better effect than the control group in controlling the diopter growth in moderate and low myopia of Asian adolescents and children. The difference between the two groups was statistically significant \〖<i>WMD</i>=0.50, 95%<i>CI </i>(0.37, 0.64), <i>P</i><0.00001\〗. And the results also indicated that the change in axial length of 0.01% atropine was significantly less than the control group, the difference between the two groups was statistically significant \〖<i>WMD</i>= -0.20, 95%<i>CI </i>(-0.30, -0.10), <i>P</i>=0.0001\〗.<p>CONCLUSION: Based on the available evidence, 0.01% atropine offer in controlling axial length and diopter growth of low and medium myopia in Asian adolescents and children.
