Prospective analysis of the predictors of glaucoma following surgery for congenital and infantile cataract.

ABSTRACT: PURPOSE:A prospective longitudinal cohort study was performed to assess the incidence of and risk factors for the development of glaucoma following surgery for congenital/infantile cataract. METHODS:One hundred and one eyes of one hundred and one children, ?12 years of age who had follow-up of ?24 months were included. Group I included those who underwent surgery using an anterior approach, group II included those who underwent surgery using a posterior approach, and group III included those who underwent surgery using an anterior approach along with foldable intraocular lens implantation. Standard definitions for glaucoma and glaucoma suspect were used. The Cox proportional hazard model was used to analyze risk factors for glaucoma. RESULTS:Group I: 30 eyes (29.7%); group II: 11 eyes (10.9%); group III 60 eyes (59.4%). The incidence of glaucoma?+?glaucoma suspect was 7.9% (95% CL: 2.6, 13.2%) in the entire group. The incidence in group I was 16.7% (95% CL 3%, 30%), in group II was 18.2% (95% CL: 0, 41%) and in group III was 1.7% (95% CL: 0, 4.9%). Gonioscopy revealed high iris insertion with grade I (modified Shaffer grading) in one eye each in the glaucoma and glaucoma suspect group and open angles in the rest. Age at surgery of ?3 months (HR: 6.6, 95% CL: 1.4, 30.6, p?=?0.01) was found to be a significant risk factor within the aphakic group. CONCLUSIONS:Younger age at the time of surgery was the only identifiable risk factor for glaucoma.

Project description:ImportanceThe p.Asp67Tyr genetic variant in the GJA3 gene is responsible for congenital cataracts in a family with a high incidence of glaucoma following cataract surgery.ObjectiveTo describe the clinical features of a family with a strong association between congenital cataracts and glaucoma following cataract surgery secondary to a genetic variant in the GJA3 gene (NM_021954.4:c.199G>T, p.Asp67Tyr).Design, setting, and participantsThis was a retrospective, observational, case series, genetic association study from the University of Iowa spanning 61 years. Examined were the ophthalmic records from 1961 through 2022 of the family members of a 4-generation pedigree with autosomal dominant congenital cataracts.Main outcomes and measuresFrequency of glaucoma following cataract surgery and postoperative complications among family members with congenital cataract due to the p.Asp67Tyr GJA3 genetic variant.ResultsMedical records were available from 11 of 12 family members (7 male [63.6%]) with congenital cataract with a mean (SD) follow-up of 30 (21.7) years (range, 0.2-61 years). Eight of 9 patients with congenital cataracts developed glaucoma, and 8 of 8 patients who had cataract surgery at age 2 years or younger developed glaucoma following cataract surgery. The only family member with congenital cataracts who did not develop glaucoma had delayed cataract surgery until 12 and 21 years of age. Five of 11 family members (45.5%) had retinal detachments after cataract extraction and vitrectomy. No patients developed retinal detachments after prophylactic 360-degree endolaser.Conclusions and relevanceThe GJA3 genetic variant, p.Asp67Tyr, was identified in a 4-generation congenital cataract pedigree from Iowa. This report suggests that patients with congenital cataract due to some GJA3 genetic variants may be at especially high risk for glaucoma following cataract surgery. Retinal detachments after cataract extraction in the first 2 years of life were also common in this family, and prophylactic retinal endolaser may be indicated at the time of surgery.

Project description:BackgroundThis study aimed to identify the incidence of and risk factors for postoperative glaucoma-related adverse events at various time points after congenital cataract surgery.MethodsThis retrospective cohort study enrolled 259 eyes from 174 patients (surgical age ≤ 7 years) who underwent congenital cataract surgery. All surgical procedures were conducted at the Eye Hospital of Wenzhou Medical University between May 2011 and March 2019. Patients were classified into group 1 [primary intraocular lens (IOL) implantation, N = 111 eyes], group 2 (secondary IOL implantation, N = 85 eyes), and group 3 (no IOL implantation, N = 63 eyes). We recorded demographic factors and incidence and risk factors for glaucoma-related adverse events.ResultsGlaucoma-related adverse events occurred in 21 (8.1%) eyes, whereas 27 (10.4%) eyes developed steroid-induced ocular hypertension. The percentage of glaucoma-related adverse events was 0%, 1.2%, 1.2%, 1.6%, 4.0%, and 8.9% at 1 month, 6 months, 1 year, 2 years, 3 years and 4 years after surgery, respectively. Sixteen (18.8%), five (7.9%), and zero eyes developed glaucoma-related adverse events in groups 2, 3, and 1, respectively. Family history of congenital cataract [hazard ratio (HR), 50.463; 95% confidence interval (CI), 7.051-361.139; P < 0.001], preoperative central corneal thickness (CCT) [HR, 1.021; 95% CI, 1.009-1.034; P = 0.001], preoperative horizontal corneal diameter (HCD) [HR, 3.922; 95% CI, 1.558-9.804; P = 0.004], and preoperative lens thickness (LT) [HR, 3.745; 95% CI, 1.344-10.417; P = 0.012] were identified as predictors of postoperative glaucoma-related adverse events.ConclusionsFamily history of congenital cataract, thicker preoperative CCT, smaller preoperative HCD, and thinner preoperative LT are the main risk factors of postoperative glaucoma-related adverse events. Regular monitoring of children after cataract surgery with these risk factors may help ophthalmologists detect susceptible individuals and provide timely interventions in the clinic.
