Lack of glaucoma 5 years following infantile cataract surgery with primary posterior chamber intraocular lens (PCIOL) implantation
Khan AO; Al-Dahmash SJournal of AAPOS 2010; 14: 21
Introduction: Delayed-onset aphakic glaucoma is especially common when cataract surgery is performed in the first 9 months of life. This study assesses the incidence of glaucoma 5 years following cataract surgery with primary PCIOL primary implantation performed before 10 months of age. Methods: A retrospective institutional medical RECORD review of cataract surgery performed before 10 months of age with primary PCIOL implantation was conducted. Only cases that included 2 consecutive measurements of intraocular pressure (IOP) at or after a 5-year postoperative visit were reviewed. Trauma, microcornea, persistent fetal vascular and/or other anterior segment developmental abnormalities were excluded. Results: Thirty-six eyes (31 patients) were identified. All had lens aspiration, posterior capsulotomy, anterior vitrectomy, and primary PCIOL implantation using small-incision surgical techniques. Surgery was at a mean 7.6 years of age (median, 7; range, 5-10; SD, 1.5). No eye (0/36) was diagnosed with glaucoma an average of 5.6 years after the procedure (median, 5.4; range, 5 -7). In a similar previously published population (same methods, ethnic group, and age range) that was left aphakic, the incidence of aphakic glaucoma was 38.6% (22/57 eyes). Conclusions: Glaucoma in this cohort was unexpectedly low. Primary PCIOL implantation may decrease the risk of the delayed-onset glaucoma that is associated with infantile aphakia.
