To compare accommodation facility and vergence facility in eyes with myopia and emmetropia.It was a hospital-based comparative study conducted in the Outpatient Department of Ophthalmology. Accommodative and vergence facility measurements were taken with accommodative and vergence flippers.This study was done on 50 subjects, age group between 18-30 Years and it was approved by the IRB committee. This study has done to compare the values of accommodative facility and vergence facility between myopic emmetropic patients. The accommodative facility was measured using accommodative flippers. It was done both monocularly and binocularly for each subject at 3m and 40cm. Vergence facility was measured using vergence flippers. It was confirmed that Accommodative facility [Distance and Near] in right eye, left eye, and botheye was observed as significantly lesser in Myopic patients than Emmetropia. Also, the Vergence facility wasobserved as significantly lesser in Myopic patients than the Emmetropic patients.A reduced accommodative facility and vergence facility was found in myopes in comparison to emmetropia. At both distance and near, the mean facility was less for myopic eyes in comparison with emmetropic eyes.

Aim: This study aimed to access the changes of accommodation and vergence before and after mobile gaming. Settings and Design: This was a comparative study conducted in the outpatient department of ophthalmology. Accommodative facility and vergence facility were measured using flippers. Methods and Materials: A comparative study was conducted on 50 healthy subjects, in both males and females, with age groups ranging between 18 and 30 years. This study has been approved by the IRB Committee; 25 young emmetropic patients and 25 young myopic patients were included. The comparison of accommodative facility and vergence facility before and after mobile gaming for 1 h was measured to determine the level of changes in accommodation and vergence. All patients were undergone comprehensive ophthalmic examination including vision, subjective/objective refraction, anterior segment examination, and accommodative and vergence facilities measured using accommodative and vergence flippers. Results: The mean and standard deviation value significantly increase before and after mobile gaming in the right eye, left eye, and both eyes in case of accommodation facility, and there is a decrease in the mean and standard deviation value in case of vergence facility in both eyes before and after mobile gaming. Conclusion: The mean and standard deviation value significantly increase before and after mobile gaming in the right eye, left eye, and both eyes in case of accommodative facility, and there is a decrease in the mean and standard deviation value in case of vergence facility in both eyes before and after mobile gaming.

Objective: To assess the level of awareness and knowledge of Color Vision Deficiency and to determine problems related to color vision among health care students. Methods: This study was done on 278 Health care students in the age group of 18 to 25 y. Structured Pre and Post assessment questionnaires were administrated to all consenting students to determine the prevalence of Color Vision Deficiency and a video is shown to assess the level of awareness and knowledge of Color Vision defects. Color Vision was tested by using Ishihara Color Vision Chart. This study was conducted between November 2021 to January 2022. Ethical clearance for the study was obtained from Saveetha College of Allied Health Sciences. Results: A total of 278 subjects participated in this study, 277(99.6%) subjects have a normal level of Color Vision. Around 66.5% of subjects were aware of color vision deficiency in pre-assessment and 100% of subjects were aware in post-assessment, around 99.6% of subjects found no difficulty in choosing colors of clothes, cosmetics, 100% of subjects had no color difficulty in previous and daily work/study activities and among them, one subject (0.35%) could not appreciate color considered as total Color blindness according to the chart used. Conclusion: It is concluded from this study that a large group of students attains a normal level of Color Vision. Most of them (66.5%) are aware of Color Vision deficiency in pre-assessment, after providing them with adequate awareness and knowledge increases to 100% in post-assessment.

The study was done to assess the pre and post awareness of eye health care and importance of regular eye test to detect ocular and systemic conditions which may be asymptomatic.This study done on 278 subjects, age group between 18-30years. 65% of the subjects are females and 35% of them are males are included. In this questionnaire study, pre and post data is collected among health care students on pre-eye examination, participants were asked questions on their demographic detail, Eye examination, visual symptoms, ocular symptoms, visual aids, safety eye wear, importance of eye examination and a pamphlet is shown to create knowledge, awareness after which post awareness data is collected.A total of 278 subjects were participated, our result showed a significant improvement in increasing awareness, knowledge level in post intervention of health care students regarding visual health awareness and eye care. Overall knowledge before intervention was low 55.43% and was increased to 87.1% after intervention.Awareness programs in eye care can have a positive effect on raising the profile of eye health services within health systems, thereby increasing the knowledge, confidence, and motivation in health care students.

Objective: The objective of our study was to assess the variations in contrast sensitivity values of normoglycemic subjects and that of type II diabetic subjects of the same age group. It was also aimed at finding the visual acuities and study the associations of it with contrast sensitivity if any. Methods: It was a hospital-based comparative cross-sectional descriptive study conducted in the out-patient department of the Department of Ophthalmology, Saveetha Medical College, Hospital, Chennai. Visual Acuity and Contrast Sensitivity of 50 Type II Diabetic individuals and 50 age-equivalent control group subjects were measured using the Snellen’s chart and Pelli-Robson chart, respectively, during the months of January to March 2020. Results: Contrast Sensitivity measurements from 50 subjects with Non-Insulin dependent Diabetes Mellitus (NIDDM) were obtained. The subjects were the ones who had minimal or no diabetic retinopathy. It was observed that there is a significant association between reduced contrast sensitivity and Diabetes (P value<.00008). We also noted that CS may be reduced without corresponding loss of Visual Acuity. Hence, both visual acuity and contrast sensitivity measurements are helpful in the assessment of visual impairment due to diabetic eye disease. Conclusion: The contrast sensitivity can be seen as an early marker for visual impairment in diabetic eye care.
