Long-term Viual Prognoi in Children after Corneal Tranplant urgery for Peter Anomaly Type I Original Reearch Article

Purpoe To evaluate the long-term viual prognoi in children with corneal tranplant urgery for Peter anomaly type I. Deign Retropective review of interventional cae erie. Method Twenty-four children treated in a univerity-baed practice were divided into two group for analyi: a younger preverbal group and an older group of children three year of age or older. Children underwent corneal tranplantation urgery (penetrating keratoplaty [PKP]) for Peter anomaly type I a infant (age range, two to 18 month). Viual acuity uing nellen or Allen chart and glaucoma and other complication were tabulated. Reult Twenty-four patient had Peter anomaly; 16 had unilateral dieae, eight had bilateral dieae. Thirty eye underwent PKP. Average age at PKP wa five month. The mean follow-up from PKP to the mot recent viit wa 78.9 month. Fifteen eye (50%) were treated for glaucoma. Five tranplant (17%) had graft rejection epiode; two of thee failed and were regrafted. ix eye (20%) required cataract urgery. One eye had a retinal detachment. Currently, 27 eye (90%) have clear graft. In the younger group of children, five of ix graft are clear (83%). In the older group of 24 eye of verbal children, even eye (29%) have viual acuity ranging from 20/20 to 20/50, ix (25%) have viual acuity ranging from 20/60 to 20/100, nine (38%) have viual acuity ranging from 20/200 to counting finger, and two eye (8%) have viual acuity of hand movement. In thi group, nine of 12 eye without glaucoma had viual acuity better than 20/100; only four of 11 eye with glaucoma were better than 20/100. Concluion Many children with PKP for Peter anomaly type I can experience good or functional viion in their operated eye. Children with glaucoma have a poorer viual prognoi.
