Ophthalmic & Physiological Optics : the... Mar 2024To review the rebound effect after cessation of different myopia control treatments. (Review)
Review
PURPOSE
To review the rebound effect after cessation of different myopia control treatments.
METHODS
A systematic review that included full-length randomised controlled studies (RCTs), as well as post-hoc analyses of RCTs reporting new findings on myopia control treatments rebound effect in two databases, PubMed and Web of Science, was performed according to the PRISMA statement. The search period was between 15 June 2023 and 30 June 2023. The Cochrane risk of bias tool was used to analyse the quality of the selected studies.
RESULTS
A total of 11 studies were included in this systematic review. Unifying the rebound effects of all myopia control treatments, the mean rebound effect for axial length (AL) and spherical equivalent refraction (SER) were 0.10 ± 0.07 mm [-0.02 to 0.22] and -0.27 ± 0.2 D [-0.71 to -0.03] after 10.2 ± 7.4 months of washout, respectively. In addition, spectacles with highly aspherical lenslets or defocus incorporated multiple segments technology, soft multifocal contact lenses and orthokeratology showed lower rebound effects compared with atropine and low-level light therapy, with a mean rebound effect for AL and SER of 0.04 ± 0.04 mm [0 to 0.08] and -0.13 ± 0.07 D [-0.05 to -0.2], respectively.
CONCLUSIONS
It appears that the different treatments for myopia control produce a rebound effect after their cessation. Specifically, optical treatments seem to produce less rebound effect than pharmacological or light therapies. However, more studies are required to confirm these results.

Meta-Analysis
BACKGROUND
The effect and safety of atropine on delaying the progression of myopia has been extensively studied, but its optimal dose is still unclear. Therefore, the purpose of this meta-analysis is to systematically evaluate the safety and effectiveness of atropine in controlling the progression of myopia, and to explore the relationship between the dose of atropine and the effectiveness of controlling the progression of myopia.
METHODS
This work was done through the data searched from PubMed, MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. The Cochrane Handbook was also used to evaluate the quality of the included studies. In addition, a meta-analysis was performed using Revman5.3 software.
RESULTS
A total of 10 randomized controlled trials (RCTs) were included. Myopia progression was mitigated greater in the atropine treatment group than that in the control group, with MD = - 0.80, 95% CI (- 0.94, - 0.66) during the whole observation period. There was a statistical difference among 0.05, 0.5, and 1.0% atropine (P = 0.004). In addition, less axial elongation was shown, with MD = - 0.26, 95% CI (- 0.33, - 0.18) during the whole observation period.
CONCLUSION
The effectiveness of atropine in controlling the progression of myopia was dose related. A 0.05% atropine was likely to be the optimal dose.

Meta-Analysis Review
OBJECTIVE
Catheter-related bladder discomfort (CRBD) is a common complication of intraoperative urinary catheterization. Various studies have evaluated the efficacy of different interventions in postoperative CRBD. The present review was performed to assess the efficacy of these interventions.
METHODS
PubMed, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) databases were systematically searched to identify randomized controlled trials (RCTs) investigating the efficacy of different drugs for the prevention of postoperative CRBD. This review evaluated the incidence and severity of CRBD after different interventions at 0, 1, 2, and 6 h postoperatively.
RESULTS
Forty-five studies including 31 different drugs were analyzed. Eleven drugs were investigated in more than two RCTs, of which dexmedetomidine, gabapentin, tolterodine, tramadol, ketamine, nefopam, oxybutynin, pregabalin, and pudendal nerve block (PNB) generally showed significantly higher efficacy than controls postoperatively. Solifenacin only showed significant efficacy compared with the control at 0 h, and intravenous lidocaine only showed significant efficacy compared with the control at 6 h. There were insufficient trials to draw conclusions regarding atropine, butylscopolamine, chlorpheniramine, clonidine, darifenacin, diphenhydramine, glycopyrrolate, intravesical bupivacaine, ketamine-haloperidol, pethidine-haloperidol, ketorolac, lidocaine-prilocaine cream, magnesium, hyoscine n-butyl bromide, oxycodone, paracetamol, parecoxib, trospium, resiniferatoxin, or amikacin. However, all but pethidine-haloperidol and chlorpheniramine showed some efficacy at various time points compared with controls.
CONCLUSION
This review suggests that dexmedetomidine, gabapentin, tolterodine, tramadol, ketamine, nefopam, oxybutynin, pregabalin, and PNB are effective in preventing postoperative CRBD. Considering the efficacy and adverse effects of all drugs, dexmedetomidine and gabapentin were ranked best.

Meta-Analysis Review
Anticholinergics have been used to treat death rattle (DR) in dying patients with palliative care. However, the effect of anticholinergics is still controversial. No quantitative summary of their effects is reported. This study aimed to systematically review and quantitatively synthesize the effect of anticholinergics on DR treatment and prophylaxis. A systematic search was performed in the electronic databases (PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature [CINAHL]) from inception to October 2021. Studies conducted to determine the effect of anticholinergics compared with other anticholinergics or placebo on noise reduction score in dying patients were included. A network meta-analysis was performed for DR treatment. The effect of anticholinergics at four hours was assessed. A pairwise meta-analysis was performed for DR prophylaxis. A total of nine studies were included with 1103 patients. Six studies were randomized controlled trials, and three studies were cohort studies. Seven studies were conducted for DR treatment, while two studies were conducted for DR prophylaxis. For DR treatment, no statistically significant difference was observed between each anticholinergic (hyoscine hydrobromide, hyoscine butyl bromide, atropine, and glycopyrrolate) and placebo and among any anticholinergics. However, the surface under cumulative ranking curve indicated that hyoscine butyl bromide had the highest surface under the cumulative ranking curve (SUCRA) with 71.3%. For DR prophylaxis, the relative risk of DR occurrence for hyoscine butyl bromide was 0.23 (0.04, 1.18; = 84.5%) compared with no treatment. This study showed no strong evidence of the regular use of anticholinergics for DR treatment. In addition, hyoscine butyl bromide appears to have a high potential for DR prophylaxis.

Ophthalmic & Physiological Optics : the... Nov 2022To provide contemporary and future estimates of childhood myopia prevalence in Africa. (Meta-Analysis)
Meta-Analysis Review
PURPOSE
To provide contemporary and future estimates of childhood myopia prevalence in Africa.
METHODS
A systematic online literature search was conducted for articles on childhood (≤18 years) myopia (spherical equivalent [SE] ≤ -0.50D; high myopia: SE ≤ -6.00D) in Africa. Population- or school-based cross-sectional studies published from 1 Jan 2000 to 30 May 2021 were included. Meta-analysis using Freeman-Tukey double arcsine transformation was performed to estimate the prevalence of childhood myopia and high myopia. Myopia prevalence from subgroup analyses for age groups and settings were used as baseline for generating a prediction model using linear regression.
RESULTS
Forty-two studies from 19 (of 54) African countries were included in the meta-analysis (N = 737,859). Overall prevalence of childhood myopia and high myopia were 4.7% (95% CI: 3.3%-6.5%) and 0.6% (95% CI: 0.2%-1.1%), respectively. Estimated prevalence across the African regions was highest in the North (6.8% [95% CI: 4.0%-10.2%]), followed by Southern (6.3% [95% CI: 3.9%-9.1%]), East (4.7% [95% CI: 3.1%-6.7%]) and West (3.5% [95% CI: 1.9%-6.3%]) Africa. Prevalence from 2011 to 2021 was approximately double that from 2000 to 2010 for all studies combined, and between 1.5 and 2.5 times higher for ages 5-11 and 12-18 years, for boys and girls and for urban and rural settings, separately. Childhood myopia prevalence is projected to increase in urban settings and older children to 11.1% and 10.8% by 2030, 14.4% and 14.1% by 2040 and 17.7% and 17.4% by 2050, respectively; marginally higher than projected in the overall population (16.4% by 2050).
CONCLUSIONS
Childhood myopia prevalence has approximately doubled since 2010, with a further threefold increase predicted by 2050. Given this trajectory and the specific public health challenges in Africa, it is imperative to implement basic myopia prevention programmes, enhance spectacle coverage and ophthalmic services and generate more data to understand the changing myopia epidemiology to mitigate the expanding risk of the African population.

To evaluate the efficacy and safety of atropine for slowing myopia progression and to investigate whether the treatment effect remains constant with continuing treatment. Studies were retrieved from MEDLINE, EMBASE, and the Cochrane Library from their inception to May 2021, and the language was limited to English. Randomized controlled trials (RCTs) and cohort studies involving atropine in at least one intervention and placebo/non-atropine treatment in another as the control were included and subgroup analysis based on low dose (0.01%), moderate dose (0.01%-<0.5%), and high dose (0.5-1.0%) were conducted. The Cochrane Collaboration and Newcastle-Ottawa Scale were used to evaluate the quality of RCTs and cohort studies, respectively. Twelve RCTs and fifteen cohort studies involving 5,069 children aged 5 to 15 years were included. The weighted mean differences in myopia progression between the atropine and control groups were 0.73 diopters (D), 0.67 D, and 0.35 D per year for high-dose, moderate-dose, and low-dose atropine, respectively (χ = 13.76; = 0.001, = 85.5%). After removing studies that provided extreme findings, atropine demonstrated a significant dose-dependent effect on both refractive change and axial elongation, with higher dosages of atropine resulting in less myopia progression ( = 0.85; = 0.004) and less axial elongation ( = -0.94; = 0.005). Low-dose atropine showed less myopia progression (-0.23 D; = 0.005) and less axial elongation (0.09 mm, < 0.001) in the second year than in the first year, whereas in high-dose atropine more axial elongation (-0.15 mm, = 0.003) was observed. The higher dose of atropine was associated with a higher incidence of adverse effects, such as photophobia with an odds ratio (OR) of 163.57, compared with an OR of 6.04 for low-dose atropine and 8.63 for moderate-dose atropine ( = 0.03). Both the efficacy and adverse effects of atropine are dose-dependent in slowing myopia progression in children. The efficacy of high-dose atropine was reduced after the first year of treatment, whereas low-dose atropine had better efficacy in a longer follow-up period.

BACKGROUND
Sialorrhea in children can be associated with adverse physical and social effects. Treatment using anticholinergic medications has been shown to offer symptomatic relief, but there is no consensus regarding which treatment is the most efficacious.
OBJECTIVE
To examine the effectiveness of anticholinergic medications for sialorrhea in children.
METHODS
A systematic review was carried out in Medline, EMBASE, Cochrane, Scopus, and the Web of Science from inception until April 29, 2020. Studies reporting original data on the efficacy of anticholinergic medications in the management of sialorrhea in children aged 0 to 17 years of age were included. This review adhered to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) standards. Data on study design, setting, population, pharmacologic intervention(s), comparator(s), outcomes, and results were extracted and summarized.
RESULTS
The search strategy identified 2,800 studies of which 27 articles were included in the synthesis, including five randomized controlled trials. Each anticholinergic undergoing experimental study (glycopyrrolate, scopolamine/hyoscine, trihexyphenidyl/benzhexol, benztropine, and atropine) showed evidence of efficacy. Adverse side effects were common. Significant heterogeneity exists in the studies' methodology and the variability of outcome measures used between studies precluded a meta-analysis.
CONCLUSIONS
Glycopyrrolate, scopolamine/hyoscine, trihexyphenidyl/benzhexol, benztropine, and atropine have all shown efficacy in the treatment of sialorrhea in children. The small number of reports and the variability in study design precluded a meta-analysis. More studies are needed with uniformity in outcome measures to help guide evidence-based decision making. A guidance table is presented.

BACKGROUND
Amblyopia is defined as impaired visual acuity in one or both eyes without demonstrable abnormality of the visual pathway, and is not immediately resolved by wearing glasses.
OBJECTIVES
In performing this systematic review, we aimed to synthesize the best available evidence regarding the effectiveness and safety of conventional occlusion therapy compared to atropine penalization in treating amblyopia.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2018, Issue 8); Ovid MEDLINE; Ovid Embase; LILACS BIREME; ClinicalTrials.gov; ISRCTN; and the WHO ICTRP on 7 September 2018.
SELECTION CRITERIA
We included randomized/quasi-randomized controlled trials comparing conventional occlusion to atropine penalization for amblyopia.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened abstracts and full-text articles, abstracted data, and assessed risk of bias.
MAIN RESULTS
We included seven trials (five randomized controlled trials and two quasi-randomized controlled trials) conducted in six countries (China, India, Iran, Ireland, Spain, and the United States) with a total of 1177 amblyopic eyes. Three of these seven trials were from the original 2009 version of the review. We assessed two trials as having a low risk of bias across all domains, and the remaining five trials as having unclear or high risk of bias for some domains.As different occlusion modalities, atropine penalization regimens, and populations were used across the included trials, we did not conduct any meta-analysis due to clinical and statistical heterogeneity. Evidence from six trials (two at low risk of bias) suggests that atropine penalization is as effective as conventional occlusion in improving visual acuity. Similar improvement in visual acuity was reported at all time points at which it was assessed, ranging from five weeks (improvement of 1 line) to 10 years (improvement of greater than 3 lines). At six months, although most participants (363/522) come from a trial rated as at low risk of bias with a precise estimate (mean difference (MD) 0.03, 95% confidence interval (CI) 0.00 to 0.06), two other trials rated as at high risk of bias produced inconsistent estimates and wide confidence intervals (MD -0.02, 95% CI -0.11 to 0.07 and MD -0.14, 95% CI -0.23 to -0.05; moderate-certainty evidence). At 24 months, additional improvement was found in both groups, but there continued to be no meaningful difference between those receiving occlusion and those receiving atropine therapies (moderate-certainty evidence).We did not find any difference in ocular alignment, stereo acuity, or sound eye visual acuity between occlusion and atropine penalization groups (moderate-certainty evidence). Both treatments were well tolerated. Atropine was associated with better adherence (moderate-certainty evidence) and quality of life (moderate-certainty evidence), but also a higher reported risk of adverse events in terms of mild reduction in the visual acuity of the sound eye not requiring treatment and light sensitivity (high-certainty evidence). Skin, lid, or conjunctival irritation were more common among participants receiving patching than those receiving atropine (high-certainty evidence). Atropine penalization costs less than conventional occlusion.
AUTHORS' CONCLUSIONS
Both conventional occlusion and atropine penalization produce visual acuity improvement in the amblyopic eye. Atropine penalization appears to be as effective as conventional occlusion, although the magnitude of improvement differed among the trials we analyzed.

Meta-Analysis
BACKGROUND
To date, guidelines on the impact and value of atropine combined with omeprazole in the treatment of acute gastritis have not been well established or well defined. This study aimed to clarify the efficacy and safety of combined atropine and omeprazole therapy for the management of patients with acute gastritis.
METHODS
Through searching the electronic database, the related literature of the combination of atropine with omeprazole in the treatment of acute gastritis were reviewed. A meta-analysis was performed after literature selection according to inclusion criteria. The treatment efficiency and the incidence of adverse reactions were used as the main outcome indicators. The odds ratios (ORs), standardized mean differences (SMDs), and 95% confidence intervals (CIs) of the two treatment regimens were analyzed.
RESULTS
This study analyzed 11 articles from the literature with a total of 1,053 subjects. The combination of atropine and omeprazole significantly improved the clinical outcomes of patients with acute gastritis compared to patients treated with combined anisodamine and omeprazole (control group). The effective rate of combined atropine and omeprazole treatment was 1.21 times higher than that observed with the control group, and the incidence of adverse reactions was 0.41 times that of the control group. Atropine combined with omeprazole significantly alleviated the clinical symptoms of the patients. The total treatment time was shortened by 0.57 days, duration of abdominal pain was shortened by 2.82 days, duration of diarrhea was reduced by 1.99 days, and the duration of nausea and vomiting was shortened by 2.68 days compared to the control group.
DISCUSSION
The combination of atropine with omeprazole in the treatment of acute gastritis demonstrated a high effective rate with few adverse reactions than. It was effective at alleviating the clinical symptoms associated with acute gastritis. The results of this study provide support for the clinical implementation of combined atropine and omeprazole in the treatment of patients with acute gastritis.

AIM
To figure out whether various atropine dosages may slow the progression of myopia in Chinese kids and teenagers and to determine the optimal atropine concentration for effectively slowing the progression of myopia.
METHODS
A systematic search was conducted across the Cochrane Library, PubMed, Web of Science, EMBASE, CNKI, CBM, VIP, and Wanfang database, encompassing literature on slowing progression of myopia with varying atropine concentrations from database inception to January 17, 2024. Data extraction and quality assessment were performed, and a network Meta-analysis was executed using Stata version 14.0 Software. Results were visually represented through graphs.
RESULTS
Fourteen papers comprising 2475 cases were included; five different concentrations of atropine solution were used. The network Meta-analysis, along with the surface under the cumulative ranking curve (SUCRA), showed that 1% atropine (100%)>0.05% atropine (74.9%) >0.025% atropine (51.6%)>0.02% atropine (47.9%)>0.01% atropine (25.6%)>control in refraction change and 1% atropine (98.7%)>0.05% atropine (70.4%)>0.02% atropine (61.4%)>0.025% atropine (42%)>0.01% atropine (27.4%)>control in axial length (AL) change.
CONCLUSION
In Chinese children and teenagers, the five various concentrations of atropine can reduce the progression of myopia. Although the network Meta-analysis showed that 1% atropine is the best one for controlling refraction and AL change, there is a high incidence of adverse effects with the use of 1% atropine. Therefore, we suggest that 0.05% atropine is optimal for Chinese children to slow myopia progression.
