Summary
Infants with delayed visual maturation (DVM) type I recover faster than type II. This study provides evidence-based recovery timelines for clinicians to inform parents about DVM prognosis.
Area of Science:
- Ophthalmology
- Pediatric Neurology
Background:
- Delayed Visual Maturation (DVM) is diagnosed retrospectively.
- Current management guidelines for DVM are lacking.
- This study provides crucial evidence-based recovery timelines for DVM.
Purpose of the Study:
- To investigate the average age of recovery in infants diagnosed with DVM.
- To establish evidence-based recovery timelines to aid clinical guidance.
- To provide prognostic information for parents of infants with DVM.
Main Methods:
- Retrospective service evaluation of 50 infants with DVM (2012-2017).
- DVM classified into type I or type II.
- Key variables recorded: gender, age at recovery, DVM type, and use of electrodiagnostic testing.
Main Results:
- Average recovery age for type I DVM: 6.708 months.
- Average recovery age for type II DVM: 13.464 months.
- Type II DVM recovery was 6.179 months longer than type I, adjusted for gender (P < 0.001).
Conclusions:
- Supports hypothesis: Type I DVM recovery is significantly shorter than type II, adjusted for gender.
- Limitation: Recovery age recorded from clinic attendance; actual recovery may precede this.
- Future research requires multi-center studies with larger samples for DVM sub-categorization.
