Penetrating Keratoplasty in Children

摘要: Abstract Retrospectively studied were 91 patients, 14 years of age or less, who had 152 penetrating keratoplasties in 107 eyes, with an average followup 30.1 months. Survival analysis showed the probability obtaining a clear graft at one year to be 60 ± 8% 45 eyes congenital opacities, 70 31 opacities from trauma and 73 acquired nontraumatic opacities. Most failures occurred during first postoperative characterized by gradual loss clarity undetermined cause. Twenty-nine percent (10) 34 corneal which vision could measured most recent visual acuity better than 6/120 (20/400). Irreversible amblyopia, glaucoma, other structural abnormalities anterior segment mental retardation complicated rehabilitation group. In post-traumatic group, was (20/400) 45% (13) 29 being limited vitreoretinal pathology, fibrous ingrowth, optic nerve damage glaucoma. Visual acquired, group 67% (20) 30 eyes. The percentage patients achieving 6/12 (20/40) congenital, post-traumatic, groups 3% (1/34), 17% (5/29), 47% (14/30), respectively. only posterior polymorphous dystrophy obtained 6/30 (20/100) better. Preoperative vascularization cornea, persistent epithelial defects, performance lensectomy-vitrectomy factors highly correlated poor survival. Vitrectomy aphakia final acuity. data indicate that keratoplasty is becoming increasingly successful children suggest future efforts should aimed toward reducing period deprivation providing more effective amblyopia therapy.
