Background: Squint, crossed eyes and deviating eyes is a condition in which the eyes do not properly align with each other when looking at an object. A child with squint may stop using the affected eye. This can lead to visual loss called amblyopia, which can become permanent unless treated early in childhood. The aim of the study was to estimate the prevalence of squint, some determinants and clinical manifestations and treatment characteristics in the studied children and adolescents in Arar, Northern Saudi Arabia. This was a cross-sectional study, conducted in Arar, Northern Saudi Arabia. The study included 156 randomly selected participants (62 male and 94 female children and adolescents). Results: This study reported squint in 14.7% of the studied sample, 26.1% were females and 73.9% were males. There was no significant relation between squint and age, other hereditary diseases or other chronic diseases but there was relation with consanguinity between parents (P=0.03). The cause of squint was eye trauma in 17.4%, surgical operation in 4.3% and neurological disease in 4.3%. Squint was right sided in 47.8% of cases, left sided in 34.8% and in both eyes in 17.4% of the studied cases. 78.3% of the cases had inward squint and 17.4% outward squint. In 8.7% of the cases squint alternate between eyes. Temporary squint found in 52.2% and 78.3% of squint cases use glasses. In all cases squint affect visual acuity. All cases received treatment (69.9% medical and 30.4% surgical) but only 52.2% cured and 43.5% had recurrence. Conclusion: This study reported squint in 14.7% of the studied sample, 73.9% were males. There was significant with sex and consanguinity between parents (P=0.03). The etiology was eye trauma, eye surgical operation and neurological disease. Large scale screening studies is mandatory. Health education of the public about causes and importance of early treatment is important

“…2,3,4,19,[21][22][23][24][25] Prevalence studies show Esotropia to be the most common form of strabismus in United Kingdom, Minnesota(USA), Nigeria, Pakistan, Tanzania, Sudan and Ethiopia. 5,16,18,[26][27][28][29] Rachael et al have proposed that geographical regions of the world with higher intensity of sunlight have exotropia as the most common form of strabismus. 30 Kashmir is a cold place with four seasons and winter temperatures going as low as -10 degree C in the capital city.…”

Introduction: Strabismus is a state of abnormal alignment of the two eyes. Current research was aimed at studying the profile of strabismus at a tertiary care hospital in Kashmir valley. Material and methods: Strabismus patients attending squint clinic of a tertiary care referral centre in Kashmir, between December, 2015 and December, 2017, across all age groups were included in this study. Patients operated previously for strabismus were excluded. Visual acuity, cycloplegic retinoscopy, stereopsis assessment were done in all patients. Strabismus was objectively measured using Prism Cover Test / Modified Krimsky method. Results: During the defined period a total of 911 patients were evaluated and included in this study. Out of these, 516 (56.6%) were females and 395(43.3%) were males. 37.1% of the study cohort were products of consanguineous marriages. History of prematurity and turbulent perinatal period was elicited in 4% and 18% of the patients respectively.As regards the pattern of strabismus in our study population 59.93% had esotropia, 36.6% had exotropia. Inferior oblique overaction and Dissociated vertical deviation were seen in 22.61% and 23.38% respectively. Duanes Retraction syndrome (0.98%), Superior oblique palsy (1.2%)Browns syndrome (0.21%), Third nerve Palsy (0.32%), LR palsy (0.65%) were the lesser common deviations noted. Conclusion: Esotropia is the most common motility disorder among patients attending a tertiary care hospital in Kashmir, in contrast to rest of India. Statistics from majority of colder regions of the world show the same inclination, further reinforcing the theory of association between sunlight and exodrift.
