A Prospective study of Myopia Progression in Children following surgical intervention for Intermittent exotropia

The purpose of this study is to prospectively study myopia progression in children who underwent surgical intervention for intermittent exotropia. Role of myopia in intermittent exotropia is reportedly due to increased accommodative demand caused by the exodeviation. The patients aged 5-15 years who fulfil the inclusion/exclusion criteria will be enrolled for the study and thoroughly counselled. At 2 weeks post- operatively, A scan biometry will be done for every patient to measure the axial length. A questionnaire will be handed over to the parents which includes questions related to risk factors associated with myopia progression. Patients will be followed up on 6 months and 12 months and they will undergo visual acuity testing, cycloplegic refraction with 3m Snellen’s chart, intraocular pressure measurement, anterior and posterior segment evaluation and A scan biometry to measure axial length (LENSTAR). Myopia progression will be analyzed and documented in terms of spherical equivalent and axial length.
