Ectopia Lentis: Clinical profiles in a large cohort of children from a Tertiary Eye Care network in India

Abstract

To study the clinical presentations, visual, and refractive profiles of children with congenital ectopia lentis in a large cohort of patients from a tertiary eye care network in India. A retrospective review of electronic medical records from December 2012 to December 2020 was conducted. Two hundred and ninety-seven consecutive children ≤18 years of age at presentation were identified and analyzed for demographic details, patient distribution, lens subluxation, visual, and refractive profiles before and after the interventions. Five hundred and ninety-four eyes of 297 (male 56%; n = 166) patients were analyzed. The mean age at presentation was 8.74 ± 3.89. Best-corrected visual acuity (BCVA) at presentation ranged from 0.3 logMAR to 3.5 logMAR; (Snellen: 6/9 – close to face [CF]) (mean 0.89 ± 0.68). High myopia (n = 201; 33.83%) and mild astigmatism (n = 340; 57.23%) were more frequent. Temporal (n = 108; 18.18%) subluxation was most common followed by superior. Lensectomy with limited vitrectomy was performed in 243 eyes of 127 patients (40.90%). Median preoperative BCVA was 1.0 (range: 0.3–3.5 logMAR; 20/40 - CF). Median postoperative BCVA was 0.5 logMAR (6/18) in the pseudophakic group and 0.6 logMAR (6/24) in the aphakic group. Spherical equivalent in myopic children reduced from −12.06 ± 6.84D to −1.57D (−0.25D to − 5.5D) in the pseudophakic group and +9.3D (+5.5D to 15.5D) in the aphakic group. This study is a large cohort of children presenting with ectopia lentis. Following intervention, an improvement in the median BCVA and refractive correction was noted in the entire cohort.
