AIMS AND OBJECTIVES
To know various causes, sex distribution, socioeconomic status, onset, severity, visual prognosis of paediatric strabismus.
METHODOLOGY
The present study was undertaken for a period of 18 months. All the patients were selected from those attending the outpatient department. 50 cases of squint were evaluated thoroughly to know the various factors responsible for squint and how it was caused.
RESULTS
Total Number of Patients who attended OPD were 72,431 (4000 per month). Total Number of Paediatric squint cases among them were 121. So, Incidence of Paediatric squint in general OP was-0.16%. In the present study of total 121 paediatric squint cases, 21 cases did not fulfil the inclusion criteria and in the remaining 100, cases were included by taking every 2nd patient. Esotropia is seen in 38 children contributing to 76% of total and exotropia is seen in 12 children contributing 24% of total cases. Most common cause of esotropia is Essential Infantile Esotropia contributing to 31% of total esotropias. Males are affected more commonly than females with an incidence of 60%. Esotropia is seen in 38 children contributing to 76% of total and exotropia is seen in 12 children contributing 24% of total cases. In this study, males are affected more commonly than females contributing to 60% of total and females constitute 40% of the total. In this study, incidence of paediatric squint is more commonly seen in lower socioeconomic population contributing 60% of the total. 15 cases are of congenital in onset constituting 30% of total and 35 cases are of acquired in onset constituting 70% of total. Small angle Esotropia and large angle Esotropia: In this study out of total 38 cases of esotropia, large angle esotropias are more common and contributing to 89% of the total. Out of total 50 cases, 16% had an angle of <15⁰ and 76% of total had an angle of 15⁰-30⁰ and 8% of total had an angle of >30⁰. Out of 50 cases, significant family history was present in 15 cases contributing to 30% of total cases. Following early recognition and prompt treatment, the prognosis is usually good. 58% of cases showed good visual improvement.
CONCLUSION
Parents are naturally worried about the child with squint eyes. So if we know the common aetiological factors, it will be easy for us to counsel the parents towards the prevention and management of this condition.
