Methods and Materials: This eight-month observational study was conducted between 2017 and 2018 recruiting 111 eyes of 101 patients reporting to ophthalmology outpatient and emergency medicine departments. Results: The demographic profile is composed of 82 (81.18%) males and 19 (18.81%) females with a mean presenting age of 33.45 and 33.57 years in males and females respectively ranging from 3 to 82 years. Sixty four (57.65%) right and 47 (42.34%) left eyes studied. Closed globe injuries accounted for 95 (85.56%) and open globe injuries were found in 16 (14.41%) eyes. Mode of injuries classified as RTA 37 (33.33%), RTA Self fall 26 (23.42%), metal-induced trauma in 9 (8.10%) and exposure to vegetative matter in 9 (8.10%), self fall at home/work in 6 (5.40%), assault in 4 (2.6%), sports-related injuries in 3 (2.7%), bull gore injuries in 3 (2.7%) and explosion injuries in 3 (2.7%) eyes. RTA and RTA self fall showed the highest relative risk and odds ratio among males compared to females. The relative risk ratio and odds ratio for RTA in males showed 0.63 and 0.31 respectively. Anterior segment injury effects were observed in all eyes and 21 (18.91%) eyes with posterior segment involvement. The associated facio-maxillary injury was seen in 58 (52.25%) eyes, orbital wall fractures in 52 (46.85%), and head injury in 26 (23.42%) eyes. Thirty (35.14%) eyes required imaging for further evaluation, of which 32 (31.68%) underwent computed tomography and 2 (1.99%) eyes subjected to magnetic resonance imaging. Fifty-three (52.47%) eyes were managed surgically, 25 (24.75%) conservatively and 23 (22.77%) medically. Conclusion: This study analysis concludes that closed globe injury is the most common ocular trauma. In middle-aged male patients, RTA-induced injuries were commonly prevalent. The most frequently associated co-morbidities were facio-maxillary trauma, lateral orbital wall fractures, and subconjunctival hemorrhage. Maximum eyes required surgical management while computed tomography provided a conventional mode of imaging. The multi-departmental management approach is essential for achieving a good medical and surgical outcome.","PeriodicalId":135031,"journal":{"name":"Journal of Ophthalmology & Clinical Research","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129452996","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}

Methods: The databases PubMed, EMBASE, Wanfang Database, CNKI, CSTJ and Cochrane Library from inception to March 2021 were searched to identify the relevant studies which evaluated the efficacy of PSR for patients under 18 years old with high myopia. The main parameters include AL, SE and BCVA. Revman software version 5.3 was used to perform the statistical analyses. Results in proportion with 95% confidence interval were calculated using dersimonian-laird model. Results: 8 studies including 383 PSR treated and 281 control eyes were finally included. Our analysis indicated that PSR could slow down the increase of AL and the loss of vision loss (P<.01). However, in the subgroup with a follow-up period shorter than three years, there was no statistical difference in BCVA changes between the PSR and control groups (WMD=-0.02, 95%CI -0.07 to 0.04, P=.58, I2=0%). The BCVA changes is significant after 3 years follow up (WMD=-0.13, 95%Cl -0.21 to -0.05, P=0.007). Conclusion: PSR can benefit children in controlling the growth of AL, SE and decrease of visual acuity. 3 years after PSR may be a critical time point. Given the limitations in our study, more research with larger sample sizes and more accurate data are required to reach a firmer conclusion.","PeriodicalId":135031,"journal":{"name":"Journal of Ophthalmology &amp; Clinical Research","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121355293","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}

A search in the national Low Grade Glioma (LGG) database was performed allowing identification of 93 children with OPGs from 21 participating centers in the UK. A variable selection procedure based on stepwise regression was applied to identify the significant risk factors that are of prognostic value to predict the need for treatment. A Receiver Operating Characteristic (ROC) curve was used to determine the optimal threshold for classifying the patients. The influence of the available risk factors on the time from diagnosis to initiation of therapy was assessed by a Cox proportional hazards model. Children without Neurofibromatosis type 1 (NF 1) were more likely to have tumour involvement of the most posterior visual pathway. Children with posterior tumour involvement and subjects with poor visual acuity (VA) and younger age at diagnosis were found to be the groups with the highest risk of receiving treatment. Three diagnostic groups (high, moderate, and low risk) were defined with respect to their estimated probability of receiving treatment. Individualized hazard function plots and point estimations for the probability of the need of treatment may modify the frequency and duration of follow-up evaluations in OPG patients.","PeriodicalId":135031,"journal":{"name":"Journal of Ophthalmology &amp; Clinical Research","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122134585","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}
