It is one of the main requisites for good quality vision as the eye works by perceiving an object by comparing the difference between the target and the background contrast difference.\u0000\u0000Aims and Objectives: To assess patterns of contrast sensitivity functions in patients in different types of refractive errors using Pelli Robson chart and also to measure the severity of refractive error within each group and compared the contrast sensitivity function with severity in different types of refractive errors.\u0000\u0000Material and Method: This cross-sectional study was conducted on 500 patients (Age range from 10 to 80 years) who presented with chief complaint of refractive errors mainly myopia and hypermetropia. Patients who had previous history of ocular surgery and other ocular co- morbidity were excluded from study. Selected patients were enrolled for the study after taking a written informed consent. The patterns of contrast sensitivity function in different types of refractive errors were recorded on a prescribed proforma with respect to: Visual acuity, type of refractive error, severity of refractive error, duration of refractive error, age of the patient, fundus examination and Contrast sensitivity. Statistical analysis was undertaken with P<0.05 significant.\u0000\u0000Results: A mild decrease in contrast sensitivity was recorded in majority of patients i.e 250 patients (50%). Maximum decrease in contrast sensitivity was seen in 31-60 years age group. A statistically significant direct correlation (P<0.05) was observed between duration and variation in contrast sensitivity. Both the refractive error showed definite decrease in contrast sensitivity and compound astigmatism showed severe decrease in contrast sensitivity.\u0000\u0000Conclusion: Despite having BCVA of 6/6, patients showed reduced contrast sensitivity, even without any retinal pathology, making it an essential part of a routine ophthalmic examination.","PeriodicalId":348405,"journal":{"name":"Journal of Ophthalmology and Advance Research","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122686828","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}

Ocular damage in cranio-orbital trauma is frequent and constitutes a major but avoidable cause of acquired monocular blindness and poor vision in adults.Thus, the aim of this work is to study the epidemiologic, clinical, therapeutic and evolutionary aspects of this clinical entity.\u0000\u0000Patients and Methods: This is a cross-sectional study with descriptive and analytical aims; retrospective over 3 years (January 1, 2019 to June 1, 2022) on 170 files of patients admitted to the ophthalmological emergency department, hospital 20 August 1953 of Casablanca, Morocco, for craniofacial trauma with orbito-ocular damage.\u0000\u0000Results: The frequency of ocular involvement was 38.6%. The average age was 27.95 years, with a male predominance (72.3%). Lesions of the anterior segment were more frequent than those of the posterior segment (16.5% versus 4.8%). The prognosis was much better in patients with closed globe trauma (96% without sequelae). Despite this, patients may still have anatomical and functional sequelae.\u0000\u0000Conclusion: Cranio-facial-orbital trauma is a public health problem in our context and affects mainly young people. It is urgent to strengthen prevention actions at various levels.","PeriodicalId":348405,"journal":{"name":"Journal of Ophthalmology and Advance Research","volume":"279 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134149267","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 aim of this study was to determine the awareness, prevalence and risk factors of CVS among medical students at the University of Bisha, Saudi Arabia.\u0000\u0000Methods: A cross-sectional study was conducted on the students registered in the faculty of medicine at the University of Bisha, Saudi Arabia. Two hundred thirty-four students were asked to fill out a predesigned online questionnaire covering sociodemographic characters, frequency of using computers, the associated symptoms and the relieving strategies.\u0000\u0000Results: The participation rate was 87.5% (n=196), of which males formed 78.1% (n=153) and females 21.9% (n=43). The age ranged from 18 to 27 years, with a mean ± SD of 21.3 ± 2.1. Participants spent variable hours using their computers with a mean ± SD of 5.1 ± 1.37. Most respondents experienced diverse symptoms (92.1%), including neck pain, headache, eye strain, redness of the eyes, dry eyes, backache and shoulder pain. Significant relationships were confirmed between the average time spent on computers daily, the onset of symptoms, the awareness of bad effects and the different symptoms encountered.\u0000\u0000Conclusion: Symptoms of computer vision syndrome are widely distributed among medical students at the University of Bisha, especially headaches which might be misinterpreted.
