Abstract Details


To assess the impact of refractive error correction following excimer laser photorefractive keratectomy (PRK) on the developmental skills of children with neurobehavioral problems using standardized developmental tests.


Magrabi hospital Aseer KSA


This is a prospective, noncomparative interventional case series of children with severe neurobehavioral disorders and bilateral high refractive errors unwilling to use refractive correction who underwent PRK. Before and after surgery, children received the Vineland Adaptive Behavior Scales-II (Vineland II) and either the Bayley III. Scales of Infant and Toddler Development (Bayley III) or the Beery Buktenica Developmental Test of Visual-Motor Skills (BeeryVMI) depending on the child’s level of development. Main outcome measures were cycloplegic refraction and improvement of domains of behavior postoperatively.


14children aged 4-11 years were included. Ten were highly myopic (-9.19±4.63D) bilaterally and 4 were highly hyperopic (+4.53±2.68D) bilaterally. They were corrected for a maximum treatment dose of -10.43D for the myopic group and+5.43D for the hyperopic group. Mean postoperative cycloplegic refraction was-1.86 ±1.85D for myopic group and +0.49±1.34D for hyperopic group. The Vineland II test showed improvement in communication(85%),socialization (57.14%), motor skills(42.85%) and adaptive behavior(42.85%)domains.The Beery VMI demonstrated improvement in visual motor,visual perception and motor coordination in 66%. The Bayley III test showed improvement in cognitive (75%), language (50%) and motor skills (50%)


Discussion: Monocular and binocular function improved and remained stable after PRK in all patients without further amblyopia therapy. This substantiates prolonged plasticity and ability to have sustainable amblyopia improvement. Long term follow up of PRK resulted in no haze Conclusion: PRK is safe and effective way of treating hyperopic anisometropic amblyopia in patients who fail traditional therapy.
