“…This may cause the AL to lengthen faster [9], resulting in myopia or even high myopia. Our study revealed that the mean AL in CEL eyes is longer than that in normal eyes [8], which is consistent with previous studies [11–15]. …”

BackgroundCongenital ectopia lentis (CEL) usually leads to refractive error and may influence the axial length development. But few investigations have reported patient demographics and the distribution of axial length (AL) before surgery in Chinese pediatric patients with CEL. To describe the distribution of AL before surgery in CEL patients and its relationship with patients’ demographics, such as age, Marfan syndrome, sex, and laterality.MethodsThis retrospective study reviewed 306 CEL patients from January 1, 2006 to December 31, 2015. One eye was randomly selected from each patient if both eyes were EL. The influences of Marfan syndrome, sex, and laterality to AL in different age subgroups were evaluated and compared. The differences of the AL between groups were assessed using the student t test or paired t-test. P-values less than 0.05 were considered statistically significant.ResultsTwo hundred forty-seven eyes were enrolled. 58.3% of all the patients had binoculus EL, 70% of all the patients were male and 36% of all the patients were diagnosed with Marfan syndrome. The mean AL of EL patients was 25.1 ± 2.5 mm. There was no statistical difference in the AL between patients with and without Marfan syndrome, and in the AL between male and female patients. There was statistical difference in AL between the EL-affected eye and the unaffected eye in monocular EL patients younger than 12 years old.ConclusionsThis study suggests that AL can be influenced by CEL, but the influence of CEL may be reduced after the age of 12 years old, which will likely provide a useful reference when considering the most appropriate time of surgery.

“…AL is known to increase at a faster rate in children younger than 10 years, 36 and AL growth has been suggested to be greater in children with EL than the normal population. 37 It is thought that retinal blur and change of focal plane can result in increased AL. 38,39 Reduced quality of retinal imaging during childhood triggers AL elongation, a phenomenon known as ''form deprivation myopia'' (FDM).…”

PURPOSE:The purpose of the study was to review the safety and stability of scleral-fixated intraocular lens (IOL) 2 years after implantation in children with idiopathic ectopia lentis (EL).METHODS:This retrospective case series enrolled children with EL managed between 2011 and 2015 at a tertiary eye hospital in the eastern of Saudi Arabia. Data were collected on age, gender, vision, isolated or syndromic pathology, intraoperative and postoperative complications, spherical equivalent refraction, and final best-corrected visual acuity (BCVA).RESULTS:The series included 18 eyes of 11 children with EL (6 males and 5 females). There were 7 bilateral and 4 unilateral cases. The median age was 3.5 years (25% quartile 1 year; range: 1–8 years). Preoperatively, fixation was absent in 3 eyes, 8 eyes were fixating but vision could not be recorded. In the remaining seven eyes, median distant visual acuity was 0.1 (25% quartile: 0.08). The median postoperative follow-up was 24 months (25% quartile, 7 months). Complications included two eyes with iris capture and one eye with lens subluxation requiring re-implantation. Postoperative BCVA was better than 20/60 in 15 (83%) eyes. At last follow-up, 6 eyes required myopic correction, 1 eye was emmetropic, and 11 eyes were hypermetropic. One eye with glaucoma was managed medically.CONCLUSION:Scleral fixated IOL in eyes of young children with EL had good visual outcomes and high stability. However, there is a high incidence of residual refractive error.

Axial growth and binocular function following bilateral lensectomy and scleral fixation of an intraocular lens in nontraumatic ectopia lentis

Abstract: Because of greater than normal axial growth, more undercorrection of the IOL power is required than is usual in bilateral surgery for nontraumatic ectopia lentis. Good or moderate levels of postoperative BF were achieved in more than half of patients.
