Abstract
To determine the demographic characteristics of pediatric cataract patients presenting to Abo El Reish Pediatric Ophthalmology Clinic and to determine intraocular pressure (IOP) elevation and gonioscopic changes after cataract extraction, secondary intraocular lens (IOL) implantation and IOL exchange in children. Patients and methods This was a retrospective, observational, analytical study. It included all children with cataract presenting from January 2016 till December 2016 at the Pediatric Ophthalmology Unit of Abo El Reish Pediatric Hospital. Secondary intraocular lens (IOL) implantation and IOL exchange cases during the same period were also included. Preoperative and operative data were analyzed. Postoperative IOP was measured in a follow up visit using Goldmann and Perkins applanation tonometers and anterior chamber (AC) angle was examined. Risk factors for elevation of IOP were analyzed. Results The incidence of increased IOP was 6.6% (10 of 151 eyes) after cataract removal, 3.2% (2 of 63 eyes) after secondary IOL implantation and 25% (2 of 8 eyes) after IOL exchange. While preoperative IOP and preoperative central corneal thickness (CCT) were found to be significant predictors of elevation of IOP, the state of aphakia/pseudophakia, age at operation, corneal diameter, cataract location and etiology, approach of cataract removal, presence of persistent hyperplastic primary vitreous (PHPV), use of steroids intra/postoperatively, presence of spherophakia or posterior lenticonus and postoperative AC angle were not associated with elevation of IOP. Conclusion The incidence of increased IOP in children undergoing cataract surgery at a very young age is very low. It seems that factors other than age at cataract surgery are important in determining whether a child will develop increased IOP or not such as preoperative CCT and preoperative IOP. IOL implantation following cataract surgery in children was not protective against postoperative IOP elevation
