Non-fundus visual prognosis indicators in cataract patients with congenital iridochoroidal colobomaOA
Purpose:To identify non-fundus visual prognosis indicators in cataract patients with congenital iridochoroidal coloboma.Methods:Medical records of patients with congenital iridochoroidal coloboma who underwent cataract surgery were reviewed.Data collected included corrected distance visual acuity(CDVA),axial length,corneal diameter,cataract grade,and intraoperative and postoperative complications.Poor postoperative visual outcome was defined as CDVA>1.0 logMAR at 1 month postoperatively.Logistic regression was performed to identify potential risk factors for poor visual outcomes.Results:A total of 42 eyes from 36 patients were included.The mean age at surgery was(45.4±8.2)years,and the mean follow-up was(7.2±3.8)months.Intraoperative complications included posterior capsule rupture(PCR)in 2 eyes and zonular dialysis(ZD)in 6 eyes.Postoperative complications included intraocular lens dislocation in 2 eyes and retinal detachment in 1 eye.CDVA improved significantly from(1.50±0.35)logMAR preoperatively to(0.80±0.52)logMAR at 1 month postoperatively(P<0.001)and(0.79±0.53)logMAR at the final visit(P<0.001).Logistic regression analysis revealed that poor postoperative visual outcomes were associated with poor preoperative CDVA(OR=16.01,95%CI:1.38 to 185.40,P=0.026),and microcornea(OR=18.65,95%CI:1.45 to 240.52,P=0.025).Conclusions:Poor preoperative CDVA and the presence of microcornea are significant predictors of poor postoperative visual outcomes in patients with congenital iridochoroidal coloboma.
