Changes in Refractive Trends Error of Children with Mixed Astigmatism

Objective To investigate changes in refractive trends error of children with mixed astigmatism.Method Sixty three patients (113 eyes) with mixed astigmatism between 3 and 16 years of age were confirmed as mixed astigmatism with cycloplegic retinoscopy.Participates were performed optometric examination annually over a 3 year period.Refractive status data were collected and trends of in refractive error changes were analyzed.Result The astigmatic values remained stable over three year period (F =0.175,P =0.840),which indicated the maximum and minimum refractive trends errors could help the evolvement.There was a statistically highly significant difference in degrees of spherical lens that appeared to gradually decreased (F =14.151,P =0.000).Conclusions Refractive status can evolve into myopia as growth and development of ocular optical components in children with mixed astigmatism.Early screening and cum correction is advantageous to the children with mixed astigmatism.It is also highly recommend that cycloplegic retinoscopy is a very important and necessary method for diagnosis and therapy of children with mixed astigmatism.
