Alexander, Adil Al-Mehiawi, Ismael Abuallut, Nir Shoham Hazon","doi":"10.2174/18743641-v17-230822-2022-61","DOIUrl":"https://doi.org/10.2174/18743641-v17-230822-2022-61","url":null,"abstract":"Background: Morquio Syndrome or Mucopolysaccharidosis Type IV (MPS IV) is a rare inherited metabolic disorder characterized by the deficiency of certain lysosomal enzymes involved in the breakdown of mucopolysaccharides. The deficiency results in proteoglycan accumulation, particularly keratan sulfate in various tissues in the body. Morquio Syndrome is classified into two subtypes: Morquio A and Morquio B, which are distinguished by the specific enzyme deficiency involved, with Morquio A being more prevalent. Morquio Syndrome commonly affects the eyes with 46.7% of diagnosed patients experiencing ocular symptoms related to the disorder. Objective: To perform a comprehensive review of the existing literature and summarize the ophthalmological manifestations of Morquio Syndrome. Methods: A methodical literature search was conducted, including papers with abstracts discussing ophthalmology or ocular pathology of “Mucopolysaccharidosis Type IV” or ” Morquio Syndrome.” Twelve relevant articles met the inclusion criteria and were included in the review. Seven of the articles consisted of case reports, collectively reporting on forty-one patients with Morquio Syndrome, primarily Morquio A. The outcome of the narrative review is an overview of the existing literature on ocular presentations of Morquio Syndrome and a summary of case report findings. Results: Forty-one different patients were identified from the included case reports, and forty patients were included as they presented with ocular pathology related to Morquio Syndrome. Corneal opacification was the most common presentation where twenty-seven patients had significant corneal opacification and seven patients had slight corneal opacification. Small, gray, spherical, dust-like opacities that dispersed among the stroma were most commonly seen in cases with corneal opacification. Other ocular presentations included decreased visual acuity, astigmatism, lens opacities, and glaucoma. Conclusion: Morquio syndrome, a rare genetic disorder, exhibits multiple ocular symptoms, with corneal opacification being the most common. While most research has concentrated on Morquio A, the more severe subtype, there's limited information on Morquio B, highlighting a need for more comparative studies. As the syndrome remains incurable, exploring new treatment avenues and understanding the reasons behind these ocular manifestations can significantly improve the quality of life for Morquio patients.","PeriodicalId":46347,"journal":{"name":"Open Ophthalmology Journal","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135923083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermal expression of the meibomian glands, along with massage and debridement, is an effective treatment for MGD. Objective: We describe a multi-modal thermal device (MGrx) to manage meibomian gland dysfunction (MGD). We observed the efficacy and safety of the MGrx to manage MGD in one 15-minute in-office session. Methods: We enrolled 37 patients in a prospective, open-label trial of the novel MGrx. Patients were enrolled with a Standard Patient Evaluation for Eye Dryness (SPEED) score > 12 or a Tear Breakup Time (TBUT) of < 6 seconds in at least one eye. After screening for eligibility, one 15-minute MGrx treatment was provided to each patient. The patient assessment consisted of a SPEED score, TBUT, and a Meibomian gland score (MGS) obtained pre-treatment and at a follow-up visit 30 days after the treatment. Results: Dry eye symptoms improved in the patient population, as measured by SPEED score, MGS, and TBUT, by 40%, 341%, and 145%, respectively (p<0.05). No adverse reactions were noted among the patients. Conclusion: A single 15-minute MGrx treatment was effective at significantly improving dry eye symptoms secondary to MGD in adult patients, as measured by SPEED score. Additionally, a single MGrx treatment improved meibomian gland function and all measures of MGD in the adult patients treated. Given the relatively low risk and efficient delivery of the MGrx treatment, a single MGrx treatment should be considered as a first-line treatment for MGD.","PeriodicalId":46347,"journal":{"name":"Open Ophthalmology Journal","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136360965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to examine the determinants of refractive errors among school-going children attending the ophthalmic clinic of AlMoosa Hospital in Saudi Arabia. Methodology: A sample of 161 school-going children were recruited voluntarily to complete a set of measures examining the determinants of refractive errors. The binary logistic regression model was applied to determine the relationship between independent and dependent variables. Results: Refractive errors were common among Saudi school-going children, with myopia being the most common type of refractive error. About 96 (59.6%) samples had myopia, 28 (17.4%) children had hyperopia and 27 (16.8%) children did not have any refractive error. Genetic traits and machine dependence were found to be significant predictors of refractive error. Conclusion: The preschool eye test and routine vision investigation should be performed on children to detect refractive errors early.","PeriodicalId":46347,"journal":{"name":"Open Ophthalmology Journal","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135647604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The condition negatively affects the quality of life through its impact on near activities, while there is a large gap in the information on its global prevalence and consensus on treatment. Objectives: The purpose of this systematic review and meta-analysis was to assess the prevalence and treatment options available for convergence insufficiency. Methods: The study was performed in 2023 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-2020) guidelines. The authors have searched Google Scholar, Research Gate, Scopus, PubMed, Index Medicus, Web of Science, and the JAMA network. This review included peer-reviewed studies published between January 2000 to January 2023 that assessed the prevalence and treatment modalities of convergence insufficiency. Results: The authors screened 13250 studies, 20 for prevalence and 15 for treatment from 12 countries that met the inclusion criteria for the study. The overall pooled prevalence of convergence insufficiency was 7.98%, and the heterogeneity between the studies was highly significant P < 0.0001. Majorities of the studies 12(80%) reported that office-based vision therapy is the most effective treatment of CI, form those studies 5(42.0%) highlighted that office-based vergence/accommodative therapy with home reinforcement is the best modality of treatment. Whereas, home-based pencil push-up therapy, vision therapy with modified refractive correction, and vision therapy with prismatic correction were reported as effective treatment options for CI. The reviewed studies showed that vision therapy is highly effective to recover from symptomatic CI in both adults and children. Conclusion: The prevalence of convergence insufficiency was high, there was highly significant heterogeneity between the reviewed studies. Office-based vergence/accommodative therapy with home reinforcement is the best modality of treatment, followed by home-based pencil push-up therapy, vision therapy with modified refractive correction, and vision therapy with prismatic correction. There is consensus among reviewed studies that vision therapy is highly effective to recover from symptomatic CI in both adults and children.","PeriodicalId":46347,"journal":{"name":"Open Ophthalmology Journal","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136381821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: This retrospective study sought to investigate real-world clinical outcomes of Caucasian PCV patients treated with polypoidal verteporfin photodynamic therapy (PDT) in combination with anti-VEGF therapy up to 36 months post-treatment. Methods: Consecutive PCV patients who received PDT between 2011 and 2017 were included. Mean change in visual acuity (VA) measured by ETDRS letter score and mean change in central subfield thickness (CST) were the main outcome measures. Data were collected at baseline, 3, 12, 24 and 36 months. Regression analyses were carried out on pre-treatment clinical features to determine if there were any factors associated with a good visual outcome (better than or equal to 70 ETDRS letters at 12 months). Results: Seventy six patients (96% Caucasian) and seventy eight eyes were included in the analysis. Mean change in VA was -1, -4, and 0 ETDRS letters at 12, 24, and 36 months, respectively. CST was reduced by a mean of -51, -54, and -55 microns at 12, 24, and 36 months, respectively. Better pre-treatment VA was the only pre-treatment clinical feature associated with a good visual outcome at 12 months (OR 1.16, p<0.001). Conclusion: PDT, in combination with anti-VEGF therapy, maintains VA and may reduce the anti-VEGF therapy burden in Caucasian patients with PCV. Better pre-treatment VA is associated with a good visual outcome.","PeriodicalId":46347,"journal":{"name":"Open Ophthalmology Journal","volume":"286 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134946413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
