The incidence of glaucoma following penetrating keratoplasty in the pediatric populations (10-year retrospective chart review)
Purpose. To evaluate the prevalence of glaucoma following penetrating keratoplasty (PKP) in a pediatric population with congenital (CCO), acquired non-traumatic (ANTCO) and acquired traumatic corneal opacities (ATCO).
Material and methods. A retrospective chart review of children ages 12 and younger who had a PKP over the past 10 years was conducted. Children had a minimal follow up time of 8 months; only first time PKPs were included. Children were stratified into 4 Groups based on age: Group 1 03 years; Group 2 46; Group 3 79, and Group 4 1012. Within each age group, patients were stratified by diagnosis. Pre- and postoperative axial length (AL), corneal diameter and intraocular pressure (IOP) were collected.
Results. We identified 102 eyes that qualified for the study. In Group 1, 34/72 eyes with CCO developed glaucoma while 11/72 developed elevated IOP; 0/4 eyes with ANTCO and 2/5 eyes with ATCO developed glaucoma. In the Group 2, 4/8 eyes with CCO, 0/4 eyes with ANTCO and 1/3 eyes with ATCO developed glaucoma. In the Group 3, 1/2 eyes with ATCO developed glaucoma. In Group 4, 2/6 ANTCO eyes developed elevated IOPs; 0/1 eye with ATCO developed glaucoma.
Conclusion. Our results confirm previous reports of a 50% incidence of glaucoma following PKP in children with CCO. Our findings show that for ANTCO no children developed glaucoma while 2233% developed glaucoma in cases of ATCO. These findings suggest that anterior segment abnormalities or trauma are likely causative of glaucoma and not damaged caused by PKP.
