The purpose of this study is to estimate the prevalence of refractive errors in children. Children of selected ages will be identified for visual acuity measurement, and primary eye examination will be performed. A cross-sectional study was conducted to evaluate the refractive errors in children in Saveetha medical college. A comprehensive eye examination was performed, and children with different types of refractive errors were found out. A total of 100 children were taken for the study. The sample size of the study is 100. Eye examination was performed, and refractive error was evaluated. The refractive errors that are most common in the affected age groups can be found out. The most common refractive error was found to be myopia, followed by hypermetropia and then astigmatism. This study helps to identify the most common type of error, and the causes can be found out. This is also helpful in the prevention of these errors. Early diagnosis will lead to proper and effective treatment. When these errors are left untreated, it can cause other severe effects in the eye. Awareness should be created among both the children and the parents about this problem, and the importance of regular eye examination can be stressed through this study.

Duane retraction syndrome is a congenital form of strabismus characterized by horizontal eye movement limitation, globe retraction and palpebral fissure narrowing in attempted abduction. DRS are present in 1% of strabismus patients. It is most commonly unilateral, but can be bilateral. It affects the left eye more frequently than the right eye and females affected more than males. Refractive error commonly associated is hypermetropia. Here we are presenting a case of a 15 year old boy with Type 1A Duane's retraction syndrome in Right eye with myopia.

This study aims to assess among the undergraduate medical students the knowledge about wear and care of contact lens and also to highlight their awareness about complications of inappropriate contact lens use. A pretested semi-structured questionnaire conducted the study. Fifty students were selected from each year to come up with a sample size of a total of 200 undergraduate medical students. Questions about the use of contact lens, hygienic practices in contact lens use and also complications related to contact lens usage were asked in the questionnaire.  Out of 200 students surveyed, only 31 participants were wearing contact lens. It was observed that in our study, 54.84% of students were using contact lens for refractive error, 29.03% for cosmetic purpose and 16.13% for convenience. 66.5% of students did not know about overwear syndrome.36.5% of students were aware that Pseudomonas is most commonly involved in contact lens-related ulcers. 73.79% spectacle users stated that they are convenient with spectacles preferably than a contact lens. About 53% of students gained knowledge about contact lens through friends and family. A good number of students were aware of most of the hygienic practices of contact lens and complications related to contact lens wear. However, education about do's and don'ts regarding contact lens should also be taught to medical students during Ophthalmology postings to make them aware of complications of contact lens usage.
