Genetics
Ophthalmology

Background:

Rett syndrome (RTT) is a rare genetic neurodevelopmental disorder.
Visual pathway dysfunction is a known feature of RTT.
Understanding visual processing in RTT is crucial for diagnosis and management.

Purpose of the Study:

To investigate visual evoked potentials (VEPs) in individuals with Rett syndrome.
To compare VEPs in girls with RTT to those in a mouse model (Mecp2 heterozygous female mice).

Main Methods:

Pattern-reversal visual evoked potentials (VEPs) were recorded.
VEPs were measured in 34 girls diagnosed with Rett syndrome.
VEPs were also recorded in Mecp2 heterozygous female mice.

Main Results:

The study recorded VEPs in both human subjects and a mouse model.
Specific VEP findings in RTT patients and the mouse model were documented.

Conclusions:

VEP analysis provides insights into visual pathway function in Rett syndrome.
Comparing human and mouse data may elucidate the underlying mechanisms of visual deficits in RTT.
