Purpose

To investigate the longitudinal behavior of the hyper-reflective ganglion cell layer band (HGB) and its association with ellipsoid zone (ellipsoid zone) constriction over time in molecularly characterized RP, based on the hypothesis that the HGB represents a manifestation of inner retinal remodeling with potential prognostic significance.

Methods

We conducted a retrospective cohort study featuring patients with typical RP caused by variants in photoreceptor-associated genes and ≥6 months follow-up.

n = 118 eyes
Results

eyes with the marker lost retinal tissue more slowly than eyes without it

Eyes with HGB

More results

HGB was detected at baseline in 27 eyes (22.9%) from 14 patients.

Over follow-up, no eyes developed or lost the HGB.

Compared with autosomal recessive RP (5.5% per year), ellipsoid zone constriction was significantly slower in autosomal dominant RP (2.8% per year; P = 0.0005) and faster in X-linked RP (7.7% per year; P = 0.021).

“
Conclusion

HGB is a relatively stable optical coherence tomography finding in RP and is associated with increased ganglion cell layer thickness and a slower rate of ellipsoid zone constriction.
