Ocular Biometry Percentile Curves and Their Relation to Myopia Development in Indian Children.

The aim of the present study was to provide ocular biometry percentile values for Indian children between the ages of 6 and 12 and to validate the usefulness of centiles in predicting myopia development. The study was part of a longitudinal study-the Sankara Nethralaya Tamil Nadu Essilor Myopia Study (STEM), where objective refraction and ocular biometry were measured for children studying in grades 1, 4, and 6 at baseline (2019-2020). These data were used to generate ocular biometry percentile curves (both for axial length (AL) and AL/corneal curvature (AL/CR) ratios).

Impact of Covid-19 on Pediatric Ophthalmology Care: Lessons Learned.

The COVID-19 pandemic came with many new challenges that forced personal and professional lifestyle modifications. Medical facilities were in scarcity against this new unknown enemy and were challenged with the overloaded patient flow, scarcity of healthcare staff, and evolving treatment modalities with a better understanding of the virus each day. Ophthalmology as a "branch of medicine" suffered challenges initially because of a lack of guidelines for patient management, close working distance during routine examinations, and halt of major surgeries, including cataracts.

Discrimination of paediatric acuity test optotypes by 6-year-old children.

Purpose: To compare the discrimination performance of 6-year-old children for optotypes from six paediatric visual acuity tests and to fit Luce's Biased Choice Model to the data to estimate the relative similarities and bias for each optotype.

Methods: Full data sets were collected from 20 typically developing 6-year-olds who had passed a vision screening. They were presented with single optotypes labelled 6/12 at a distance of 9 m and were asked to identify the optotype using a matching task containing all optotypes from the relevant test.

Purpose: To measure the pupillary dynamics and accommodative response in individuals with mild traumatic brain injury (mTBI) as compared to age-matched controls.

Materials And Methods: This prospective comparative study was carried out at the neuro-optometry clinic of a tertiary eye care hospital. Sixty-three subjects with a history of mTBI and ninety age-matched controls were enrolled in this study.

Parental perception of facilitators and barriers to activity and participation in an integrated tele-rehabilitation model for children with cerebral visual impairment in South India - A virtual focus group discussion study.

Purpose: This study utilized virtual focus group discussions to document the facilitators and barriers reported by the parents as part of the tele-rehabilitation service delivery model in India.

Methods: This study included 17 participants who were enrolled into the Tele-rehabilitation program (16 mothers, 1 father) and the virtual focus group discussion (V-FGD) were conducted through a WhatsApp video call. Three V-FGDs were conducted involving two moderators and a note taker.

Myopia and Its Association with Near Work, Outdoor Time, and Housing Type among Schoolchildren in South India.

Significance: In this comprehensive assessment of environmental associations with refractive status among schoolchildren in India, outdoor time was the key modifiable risk factor associated with myopia rather than time spent on near work.

Purpose: This study aimed to investigate the environmental risk factors associated with myopia among adolescent schoolchildren in South India.

Methods: Children in grades 8 to 10 from 11 schools in Tamil Nadu, South India, underwent eye examination and risk factor assessments through a modified version of the Sydney myopia questionnaire.

Results of the School Children Ocular Biometry and Refractive Error Study in South India.

Objectives: Axial length (AL) is an important contributor to refraction, and growth curves are gaining importance in the prediction of myopia. This study aimed to profile the distribution of ocular biometry parameters and to identify correlates of spherical equivalent refraction (SE) among school children in South India.

Materials And Methods: The School Children Ocular Biometry and Refractive Error study was conducted as part of a school screening program in southern India.

Reading Difficulty Due to Oculomotor Dysfunction following Mild Traumatic Brain Injury: A Case Report.

Reading involves adequate coordination of the oculomotor system. As interlink consists of neuronal control, an insult to the brain might affect the signal processing and lead to oculomotor dysfunction that can affect reading performance. Appropriate training to enhance the oculomotor coordination is effective in such scenarios.

Diagnostic accuracy of indigenously developed computer-based binocular vision assessment.

Context: The increased prevalence of nonstrabismic binocular vision anomalies (NSBVA) has given rise to the need for cost-effective screening and diagnostic tools.

Aims: The aim of the study is to assess the efficacy of an indigenously developed computer-based binocular vision assessment software (Train Your Eyes®) in screening NSBVA.

Subjects And Methods: Subjects who visited the binocular vision clinic of a tertiary eye care center with asthenopic symptoms between January 2019 and January 2020 were included in the study.

Digital Eye Strain- A Comprehensive Review.

Digital eye strain (DES) is an entity encompassing visual and ocular symptoms arising due to the prolonged use of digital electronic devices. It is characterized by dry eyes, itching, foreign body sensation, watering, blurring of vision, and headache. Non-ocular symptoms associated with eye strain include stiff neck, general fatigue, headache, and backache.

Diagnosis and Management of Post Traumatic Recurrent Unilateral Accommodative Spasm-A Case Report.

Spasm of accommodation refers to constant contraction of the ciliary muscles of the eye, which fail to relax. Neurological issues, head injury, and psychogenic factors can lead to spasm of accommodation, which is generally bilateral. This case report describes the clinical presentation of traumatic, unilateral accommodative spasm in an army person.
