Insights
Early correction of refractive errors and limited eye patching in children with combined corneal-lens perforating injuries led to high rates of good visual acuity and binocular vision.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Trauma Surgery
Background:
- Combined perforating injuries of the cornea and lens in children are severe ocular traumas.
- Optimal management strategies for these injuries are crucial for visual outcome.
Purpose of the Study:
- To evaluate the efficacy of a specific treatment protocol for pediatric corneal-lens perforating injuries.
- To assess the impact of early refractive correction and selective occlusion on visual acuity and binocularity.
Main Methods:
- A consecutive series of twelve children under ten years with combined corneal-lens perforating injuries were treated.
- Treatment included lensectomy, corneal suture (11/12), early refractive error correction (contact lens/bifocal glasses), and selective eye occlusion for strabismus.
Main Results:
- Nine out of twelve children achieved visual acuity of 20/40 or better.
- Eight children developed orthotropia with binocular single vision.
- These outcomes compare favorably to previously reported results in the literature.
Conclusions:
- Early and comprehensive refractive error correction is vital for favorable visual outcomes.
- Restricting occlusion therapy to cases with manifest strabismus improves the chances of achieving binocular single vision.
Abstract:
Twelve consecutive children under the age of ten years who were referred to the authors' hospital between 1990 and 1993 with a combined perforating injury of the cornea and the lens were treated as follows: lensectomy, corneal suture (in 11 of them) and, shortly after surgery, correction of the refractive error with a contact lens and a bifocal glass. The other eye was occluded only if there was a manifest strabismus and if binocular single vision appeared unattainable. In nine children visual acuity was ≥ 20/ 40, eight children had orthotropia with binocular single vision. Compared with other reports in the literature the percentage of children with orthotropia and binocular single vision was high. The authors suggest that two factors explain the favourable results: (I) early correction of the refractive error for far and near vision and (2) restriction of occlusion therapy to cases with a manifest strabismus.
