    Usher syndrome type 1B (USH1B) is an autosomal recessive disorder characterized by retinitis pigmentosa and profound sensorineural hearing loss.

  • 2

    Cystoid macular edema (CME) occurs in 10-50% of retinitis pigmentosa patients and is one of the few treatable causes of vision loss.

  • 3

    A 3-year-old boy with genetically confirmed USH1B experienced spontaneous resolution of bilateral CME after conservative management.

  • 4

    The child exhibited accelerated axial elongation during the same period, though its relationship to USH1B is unclear.

  • 5

    This case emphasizes the potential for retinal recovery in pediatric Usher syndrome and the need for individualized treatment assessments.
