Design Interventi onal case series. Methods Prospective nonrandomized case series of 36 eyes of 36 patients under age 15 years who underwent primary placement of an anteriorly wr apped spherical porous polyethylene orbital implant from March 1998 to August 20 02, with at least 17 months of follow up. Results The mean age at the time of s urgery was 4.6 years. The histopathologic diagnoses after enucleation included i ntraocular tumor in 22 patients, phthisis bulbi in eight patients, microphthalmo s in three patients, Coats disease in two patients, and ruptured traumatic globe in one patient. Twelve patients (33%) had prior ocular surgery. At the time of enucleation, all patients underwent primary placement of spherical porous polye thylene orbital implant anteriorly wrapped with homologous sclera in 30 patients (83%) and autologous sclera in six patients (17%). The spherical implant size was 16 mm in one patient (3%), 18 mm in 10 patients ( 28%), and 20 mm in 25 p atients (69%). The prosthesis was fitted after a mean interval of 5 weeks. Afte r a mean follow up of 44 months (range, 17 to 68 months), there was one case of pyogenic granuloma (3%) and one case of implant exposure (3%). There were no cases of implant extrusion, superior sulcus syndrome, orbital cellulitis, or sig nificant inflammatory response. No porous polyethylene orbital implant was drill ed for peg placement. Conclusions Anteriorly wrapped primary porous polyethylene orbital implant in the pediatric population appears to be well tolerated with f ew complications.展开更多
