Conclusions
- Long-term retinal changes in BNS have not been described in the literature, and visual acuity often does not correlate with severity of chorioretinal atrophy present.5
- Subtlety of the chorioretinal findings in early stages may delay a diagnosis, so regular follow-up is necessary.
- Early diagnosis is beneficial to begin hormone substitution, implement visual aids, participate in balance and speech therapy, and receive genetic counseling.3
