Low-dose atropine 0.01% for the treatment of childhood myopia: a pan-India multicentric retrospective study.

OBJECTIVE: The objective of this study was to assess the efficacy of low-dose atropine 0.01% in controlling myopia progression among Indian children over a 2-year period. METHODS: This retrospective study, conducted across 20 centres in India, monitored the progression of myopia over 2 years after initiating treatment with 0.01% atropine eye drops. This included children between 6 and 14 years with baseline myopia ranging from -0.5 D to -6 D, astigmatism≤-1.5 D, anisometropia ≤ -1 D and documented myopia progression of ≥0.5 D in the year prior to starting atropine. Subjects with any other ocular pathologies were excluded. RESULTS: A total of 732 children were included in the data analysis. The mean age of the subjects was 9.3±2.7 years. The mean myopia progression at baseline (1 year before starting atropine) was -0.75±0.31 D. The rate of myopia progression was higher in younger subjects and those with higher baseline myopic error. After initiating atropine, myopia progression significantly decreased to -0.27±0.14 D at the end of the first year and -0.24±0.15 D at the end of the second year (p<0.001). Younger children (p<0.001) and higher baseline myopia (p<0.001) was associated with greater myopia progression and poor treatment response (p<0.001 for both). CONCLUSION: Low-dose atropine (0.01%) effectively reduces myopia progression over 2 years in Indian children.

Low concentration atropine and myopia: a narrative review of the evidence for United Kingdom based practitioners.

The prevalence of myopia is increasing across the world. Controlling myopia progression would be beneficial to reduce adverse outcomes such as retinal detachment and myopic maculopathy which are associated with increased axial length. Pharmacological control of myopia progression with atropine has been investigated since the 19th century and the benefits of slowing myopia progression are considered against the side-effects of near blur and photophobia. More recently, randomised trials have focused on determining the optimum concentration of atropine leading to low-concentration atropine being used to manage myopia progression by practitioners across the world. Currently, in the United Kingdom, there is no licensed pharmacological intervention for myopia management. The aim of this review is to interpret the available data to inform clinical practice. We conducted a narrative review of the literature and identified peer-reviewed randomised controlled trials using the search terms 'myopia' and 'atropine', limited to the English language. We identified two key studies, which were the Atropine in the Treatment Of Myopia (ATOM) and Low-concentration Atropine for Myopia Progression (LAMP). Further studies were identified using the above search terms and the references from the identified literature. Atropine 0.01% has a modest effect on controlling axial length progression. Atropine 0.05% appears to be superior to atropine 0.01% in managing myopia progression. There is a dose-dependent rebound effect when treatment is stopped. Atropine is a well-tolerated, safe, and effective intervention. Treatment would be needed for several years and into adolescence, until axial length progression is stable.

Juvenile-onset myopia-who to treat and how to evaluate success.

The risk of eye diseases such as myopic macular degeneration increases with the level of myopia, but there is no safe level of myopia and the burden of lower degrees of myopia remains considerable. Effective treatments are available that slow progression and thus limit the final degree of myopia. In this review, the rationale for slowing progression is summarized, and a case made for treating all myopic children. Measurement of refractive error and axial length is reviewed, stressing the precision of optical biometry, but also the need for cycloplegic autorefraction. The factors influencing progression are considered and the available tools for interpretation of progression rate are discussed. Finally, the need to set attainable treatment goals is emphasized.

Real-world outcomes of low-dose atropine therapy on myopia progression in an Australian cohort during the COVID-19 pandemic.

BACKGROUND: To report the outcomes of low-dose atropine (0.01% and 0.05%) for preventing myopia progression in a real-world Australian cohort during the COVID-19 pandemic. METHODS: Records of children presenting with myopia, from January 2016 to 2022, were retrospectively reviewed at a comprehensive ophthalmic practice. Children who discontinued treatment, ages >18, and cases with hereditary conditions were excluded. The rate of progression of myopia after treatment with atropine was compared with historical data to evaluate the effectiveness of the regime. RESULTS: One hundred and one children (mean baseline spherical equivalent [SphE] [-3.70 +/- 2.09 D] and axial length [AL] [24.59 +/- 1.00 mm]) were analysed. The mean age of the children was 10.4 +/- 2.89 years and 61% were females. The average follow-up time was 17.9 +/- 12.5 months. The mean rate of progression of AL and SphE on 0.01% atropine eyedrops was 0.219 +/- 0.35 mm and - 0.250 +/- 0.86 D/year, respectively. 68.1% of the children treated with 0.01% atropine were mild progressors (<0.5 D change/year). Non-responders when commenced on a higher dose of atropine (0.05%) experienced a 93% (p = 0.012) and 30% reduction in SphE and AL growth rate, respectively. Family history, higher myopia or younger age at baseline and shorter duration of treatment were associated with steeper progression (p < 0.01). Both doses were well tolerated. CONCLUSIONS: Low-dose atropine was shown to be beneficial in a real-world clinical setting, despite interruptions to follow-ups secondary to COVID-19 pandemic. A 0.05% dose of atropine may be effective in cases where 0.01% was ineffective.

Repeated Low-Level Red Light Therapy for the Control of Myopia in Children: A Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Repeated low-level red light (RLRL) therapy has been suggested to be effective in children with myopia. However, evidence from randomized controlled trials (RCTs) is still limited. We performed a meta-analysis of RCTs to systematically evaluate the efficacy of RLRL on changes of axial length (AL) and cycloplegic spherical equivalent refraction (SER) in children with myopia. METHODS: Relevant RCTs were obtained through a search of electronic databases including PubMed, Embase, Cochrane Library, Wanfang, and China National Knowledge Infrastructure from inception to September 15, 2022. A random-effects model was used to pool the results after incorporating the influence of potential heterogeneity. Subgroup analyses were performed according to the control treatment and follow-up duration. RESULTS: A total of seven RCTs involving 1,031 children with myopia, aged 6 to 16 years, were included in the meta-analysis. Compared with control treatment without RLRL, treatment with RLRL was associated with a significantly reduced AL (mean difference [MD]: -0.25 mm, 95% confidence interval [CI]: -0.32 to -0.17, P <0.001; I 2 =13%) and a significantly increased cycloplegic SER (MD: 0.60 D, 95% CI: 0.44-0.76, P <0.001; I 2 =20%). Further subgroup analyses showed consistent results in studies comparing children wearing single vision lenses and those receiving active treatment including orthokeratology or low-dose atropine eye drops, as well as studies of treatment duration of 6 and 12 months. CONCLUSIONS: Results of the meta-analysis suggested that RLRL treatment is effective for slowing down the progression of myopia in children aged 6 to 16 years.

A comparative study to evaluate the effect of various postoperative treatment protocols on dry eye and patient satisfaction after phacoemulsification.

Purpose: Foreign body sensation and irritation are common after cataract surgery, as is the exacerbation of dry eye disease if present. This study compared postoperative dry eye treatments and patient satisfaction. Methods: Age-related cataract patients undergoing phacoemulsification were recruited and were divided randomly into 4 postoperative treatment groups: Group A: Antibiotic + Steroids; Group B: Antibiotic + Steroids + Mydriatic; Group C: Antibiotic + Steroids + Mydriatic + Non-steroidal Ant-inflammatory drugs (NSAIDs); Group D: Antibiotic + Steroids + Mydriatic + NSAID + Tear substitute. Patients were assessed at 1, 3, and 5 weeks post-operatively for uncorrected distance and near vision, best corrected visual acuity (BCVA) for distance and near, Schirmer's-1 test, and Tear Film Break-Up Time test. At each visit, patients were assessed for dry eye-related subjective parameters using Ocular Surface Disease Index questionnaire. Results: Study participants numbered 163. (87 male and 76 female patients). No statistically significant difference was present in visual acuity for near and distance. The mean values of Schirmer's test and TFBUT were better in group D patients at each postoperative visit, with significant differences noted in comparison with other groups. The patient response to pain and dry eye symptoms was superior in groups C and D, with group D producing the best results. Compared to group A, patients in groups C and D were more satisfied with their vision and surgery. Conclusion: The addition of tear substitutes to steroids and NSAIDs has been associated with decreased dry eye-related symptoms and a better subjective feeling of vision, although no significant difference was noted in vision measured objectively.

Medical interventions for traumatic hyphema.

BACKGROUND: Traumatic hyphema is the entry of blood into the anterior chamber, the space between the cornea and iris, following significant injury to the eye. Hyphema may be associated with significant complications that uncommonly cause permanent vision loss. Complications include elevated intraocular pressure, corneal blood staining, anterior and posterior synechiae, and optic nerve atrophy. People with sickle cell trait or disease may be particularly susceptible to increases in intraocular pressure and optic atrophy. Rebleeding is associated with an increase in the rate and severity of complications. OBJECTIVES: To assess the effectiveness of various medical interventions in the management of traumatic hyphema. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2022, Issue 3); MEDLINE Ovid; Embase.com; PubMed (1948 to March 2022); the ISRCTN registry; ClinicalTrials.gov; and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). The last date of the search was 22 March 2022. SELECTION CRITERIA: Two review authors independently assessed the titles and abstracts of all reports identified by the electronic and manual searches. We included randomized and quasi-randomized trials that compared various medical (non-surgical) interventions versus other medical interventions or control groups for the treatment of traumatic hyphema following closed-globe trauma. We applied no restrictions on age, gender, severity of the closed-globe trauma, or level of visual acuity at time of enrollment. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane and assessed the certainty of evidence using GRADE. MAIN RESULTS: We included 23 randomized and seven quasi-randomized studies with a total of 2969 participants. Interventions included antifibrinolytic agents (systemic and topical aminocaproic acid, tranexamic acid, and aminomethylbenzoic acid), corticosteroids (systemic and topical), cycloplegics, miotics, aspirin, conjugated estrogens, traditional Chinese medicine, monocular versus bilateral patching, elevation of the head, and bed rest. We found no evidence of an effect on visual acuity for any intervention, whether measured within two weeks (short term) or for longer periods. In a meta-analysis of two trials, we found no evidence of an effect of aminocaproic acid on long-term visual acuity (RR 1.03, 95% confidence interval (CI) 0.82 to 1.29) or final visual acuity measured up to three years after the hyphema (RR 1.05, 95% CI 0.93 to 1.18). Oral tranexamic acid appeared to provide little to no benefit on visual acuity in four trials (RR 1.12, 95% CI 1.00 to 1.25). The remaining trials evaluated the effects of various interventions on short-term visual acuity; none of these interventions was measured in more than one trial. No intervention showed a statistically significant effect (RRs ranged from 0.75 to 1.10). Similarly, visual acuity measured for longer periods in four trials evaluating different interventions was also not statistically significant (RRs ranged from 0.82 to 1.02). The evidence supporting these findings was of low or very low certainty. Systemic aminocaproic acid reduced the rate of recurrent hemorrhage (RR 0.28, 95% CI 0.13 to 0.60), as assessed in six trials with 330 participants. A sensitivity analysis omitting two studies not using an intention-to-treat analysis reduced the strength of the evidence (RR 0.43, 95% CI 0.17 to 1.08). We obtained similar results for topical aminocaproic acid (RR 0.48, 95% CI 0.20 to 1.10) in two trials with 131 participants. We assessed the certainty of the evidence as low. Systemic tranexamic acid had a significant effect in reducing the rate of secondary hemorrhage (RR 0.33, 95% CI 0.21 to 0.53) in seven trials with 754 participants, as did aminomethylbenzoic acid (RR 0.10, 95% CI 0.02 to 0.41), as reported in one study. Evidence to support an associated reduction in risk of complications from secondary hemorrhage (i.e. corneal blood staining, peripheral anterior synechiae, elevated intraocular pressure, and development of optic atrophy) by antifibrinolytics was limited by the small number of these events. Use of aminocaproic acid was associated with increased nausea, vomiting, and other adverse events compared with placebo. We found no evidence of an effect on the number of adverse events with the use of systemic versus topical aminocaproic acid or with standard versus lower drug dose.  The number of days for the primary hyphema to resolve appeared to be longer with the use of systemic aminocaproic acid compared with no use, but this outcome was not altered by any other intervention. The available evidence on usage of systemic or topical corticosteroids, cycloplegics, or aspirin in traumatic hyphema was limited due to the small numbers of participants and events in the trials. We found no evidence of an effect between a single versus binocular patch on the risk of secondary hemorrhage or time to rebleed. We also found no evidence of an effect on the risk of secondary hemorrhage between ambulation and complete bed rest. AUTHORS' CONCLUSIONS: We found no evidence of an effect on visual acuity of any of the interventions evaluated in this review. Although the evidence was limited, people with traumatic hyphema who receive aminocaproic acid or tranexamic acid are less likely to experience secondary hemorrhage. However, hyphema took longer to clear in people treated with systemic aminocaproic acid. There is no good evidence to support the use of antifibrinolytic agents in the management of traumatic hyphema, other than possibly to reduce the rate of secondary hemorrhage. The potentially long-term deleterious effects of secondary hemorrhage are unknown. Similarly, there is no evidence to support the use of corticosteroids, cycloplegics, or non-drug interventions (such as patching, bed rest, or head elevation) in the management of traumatic hyphema. As these multiple interventions are rarely used in isolation, further research to assess the additive effect of these interventions might be of value.

Effect of Atropine 0.01% Eye Drops on the Difference in Refraction and Axial Length between Right and Left Eyes.

INTRODUCTION: This study sought to determine whether the application of 0.01% atropine eye drops could impact the disparity in refraction and axial length (AL) between the right and left eyes in Chinese children. METHODS: The study was designed as a double-blind, placebo-controlled randomized trial. A total of 220 children aged 6-12 years were recruited from the Beijing Tongren Hospital in Beijing, China. Participants were randomized in a 1:1 ratio and were prescribed 0.01% atropine or placebo eye drops to be administered once a night to both eyes for the duration of 1 year. The cycloplegic refraction and AL were recorded including baseline, 6 months, and again at the 12 months. RESULTS: After 1-year follow-up period, 76 (69%) and 83 (75%) subjects of the initial 220 participants were identified as the 0.01% atropine and placebo groups, respectively. The inter-ocular difference in spherical equivalent refraction (SER) and AL demonstrated stable values in the 0.01% atropine treatment group (SER: p = 0.590; AL: p = 0.322) analyzed after 1 year, but found a significant increase (SER: p < 0.001; AL: p = 0.001) in the placebo group. Furthermore, over 1 year, eyes with greater myopia in the atropine group exhibited slower myopia progression (0.45 ± 0.44 D) than the lesser myopic eye (0.56 ± 0.44 D) (p = 0.003). CONCLUSION: This study demonstrated that 0.01% atropine could maintain the inter-ocular SER and AL difference. And 0.01% atropine appeared to be more effective in delaying the progression of myopia in eyes with more myopia than in the less myopic eyes.

Accommodative spasm and its different treatment approaches: A systematic review.

This article is about the accommodation spasm. The primary rule for near vision is ciliary muscle constriction, synchronised convergence of both eyes, and pupil constriction. Any weaknesses in these components could result in an accommodative spasm. Variable retinoscopic reflex, unstable refractive error, and lead of accommodation in near retinoscopy are common causes of spasm. We conducted a thorough literature search in the PubMed and Google Scholar databases for published journals prior to June 2022, with no data limitations. This review contains twenty-eight case reports, six cohort studies, four book references, four review articles, and two comparative studies after applying the inclusion and exclusion criteria. The majority of studies looked at accommodative spasm, near reflex spasm, and pseudomyopia. The most common causes of accommodative spasm are excessive close work, emotional distress, head injury, and strabismus. Despite side effects or an insufficient regimen, cycloplegic drops are effective in diagnosing accommodation spasm. The modified optical fogging technique is also effective and may be an option for treating accommodative spasm symptoms. Bifocals for near work, manifest refraction, base-in prisms, and vision therapy are some of the other management options. As a result, it requires a comprehensive clinical treatment strategy. This review aims to investigate the various aetiology and treatments responsible for accommodative spasm and proposes widely implementing the modified optical fogging method and vision therapy in clinics as comprehensive management to reduce the future upward trend of accommodative spasm.

Efficacy Comparison of Repeated Low-Level Red Light and Low-Dose Atropine for Myopia Control: A Randomized Controlled Trial.

Purpose: To compare the treatment efficacy between repeated low-level red light (RLRL) therapy and 0.01% atropine eye drops for myopia control. Methods: A single-masked, single-center, randomized controlled trial was conducted on children 7 to 15 years old with cycloplegic spherical equivalent refraction (SER) ≤ -1.00 diopter (D) and astigmatism ≤ 2.50 D. Participants were randomly assigned to the RLRL group or low-dose atropine (LDA, 0.01% atropine eye drops) group and were followed up at 1, 3, 6, and 12 months. RLRL treatment was provided by a desktop light therapy device that emits 650-nm red light. The primary outcome was the change in axial length (AL), and the secondary outcome was the change in SER. Results: Among 62 eligible children equally randomized to each group (31 in the RLRL group, 31 in the LDA group), 60 children were qualified for analysis. The mean 1-year change in AL was 0.08 mm (95% confidence interval [CI], 0.03-0.14) in the RLRL group and 0.33 mm (95% CI, 0.27-0.38) in the LDA group, with a mean difference (MD) of -0.24 mm (95% CI, -0.32 to -0.17; P < 0.001). The 1-year change in SER was -0.03 D (95% CI, -0.01 to -0.08) in the RLRL group and -0.60 D (95% CI, -0.7 to -0.48) in the LDA group (MD = 0.57 D; 95% CI, 0.40-0.73; P < 0.001). The progression of AL < 0.1 mm was 53.2% and 9.7% (P < 0.001) in the RLRL and LDA groups, respectively. For AL ≥ 0.36 mm, progression was 9.7% and 50.0% (P < 0.001) in the RLRL and LDA groups, respectively. Conclusions: In this study, RLRL was more effective for controlling AL and myopia progression over 12 months of use compared with 0.01% atropine eye drops. Translational Relevance: RLRL therapy significantly slows axial elongation and myopia progression compared with 0.01% atropine; thus, it is an effective alternative treatment for myopia control in children.

The Mydriatic Red Eye as the Initial Presentation of Syphilis.

BACKGROUND: Syphilis is a sexually transmitted infection that has been increasing in prevalence since the early 2000s. Ocular involvement occurs in a minority of patients and must be in the differential diagnosis for patients who present with red eye and uveitis. CASE REPORT: A 29-year-old woman presented to the emergency department with a painful, mydriatic red eye. Review of systems revealed a rash as well as a recent genital lesion and, on further questioning, she admitted to a history of intravenous drug use and high-risk sexual activity. Ophthalmology was consulted and the patient was diagnosed with bilateral uveitis. Serologic testing was positive for syphilis, and she was admitted and treated with intravenous penicillin, with resolution of her uveitis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Red eye is a common ocular symptom in patients presenting to the emergency department. The differential diagnosis of the red eye is broad and can range from benign etiologies, such as conjunctivitis, to life- and sight-threatening conditions, such as endogenous endophthalmitis. Systemic diseases such as syphilis may present with primarily ocular symptoms, and ocular syphilis must be identified and managed appropriately to prevent devastating sequelae.

Does methylphenidate treatment affect functional and structural ocular parameters in patients with attention deficit hyperactivity disorder? - A prospective, one year follow-up study.

Purpose: Methylphenidate hydrochloride, which blocks the reuptake mechanisms of dopamine and norepinephrine, is used in attention deficit hyperactivity disorder (ADHD) treatment. Methylphenidate has many general side effects including ocular findings. In this study, we investigated the long-term effects of methylphenidate treatment on functional and structural ocular parameters. Methods: In this prospective study, children with ADHD were evaluated. All patients underwent a detailed ophthalmic examination before methylphenidate treatment. All patients were examined in the 3rd, 6th, 9th, 12th months of methylphenidate treatment. Visual acuities, color vision, pupil diameters, static, dynamic and cycloplegic retinoscopy, intraocular pressure (IOP), anterior chamber depth (ACD), axial length (AL) were evaluated and recorded. Results: A total of 22 children were included in this study. The best-corrected visual acuities (BCVA) of all patients for both eyes were 0.0 logMAR, and 90.9% of patients had blue-purple color weakness before the treatment. After 1 year of treatment, none of the patients had any change in BCVA and color vision. However, an increase in myopic values of static retinoscopy and a decrease in hyperopic values of cycloplegic retinoscopy were found. Additionally, accommodation capacities were found to be decreased and AL was found to be increased significantly for both eyes. Pupil diameter, IOP, and ACD values did not change significantly. Conclusion: Our results suggest that patients with ADHD may have blue color vision deficiencies because of the decreased retinal dopamine levels. Additionally, structural and ocular parameters, especially accommodation capacity, may be affected by methylphenidate treatment.

Do mydriatics effect serous pigment epithelial detachment elevation? A case report on central serous chorioretinopathy.

This report aimed to determine if pupil-dilating eye drops (mydriatics) affected serous pigment epithelial detachment elevation in an eye with central serous chorioretinopathy using spectral domain-optical coherence tomography. A 47-year-old man presented to our clinic with metamorphopsia in his right eye, which had best corrected visual acuity of 20/20. Spectral domain-optical coherence tomography revealed minimal subretinal fluid and serous pigment epithelial detachment. During the follow-up examination after the final diagnosis of central serous chorioretinopathy and serous pigment epithelial detachment, different pigment epithelial detachment elevations on optical coherence tomography images before and after pupil dilation were found incidentally. These elevations were re-measured separately on different days before and after pupil dilation with 2.5% phenylephrine and 1% tropicamide to determine if this was a mydriatic-induced increase in pigment epithelial detachment elevation, which was eventually found to be the case. Mydriatics appeared to affect pigment epithelial detachment elevation in central serous chorioretinopathy. A thorough consideration of pre-dilation ocular examination and imaging data in central serous chorioretinopathy may be valuable.
