Abstract Purpose:We describe a case of retinitis pigmentosa(RP)caused by a single homozygous PDE6A mutations.

Case:The patient was a 67-year-old woman born to consanguineous parents. Her brother was diagnosed with RP at 5 years of age. She developed night blindness at 10 years of age and was diagnosed with RP at 15 years of age by a local doctor. She was referred to our hospital at 60 years of age. Her best-corrected visual acuity(BCVA)was 0.1 in both eyes, and fundoscopy revealed bone spicule pigmentation, narrowed retinal vessels, waxy pallor of the optic discs, and macular atrophy. Goldmann perimetry revealed concentric constriction with a residual temporal island. Optical coherence tomography revealed thinned retinal layers and a disrupted ellipsoid zone. Genetic analysis revealed a single homozygous PDE6A mutations in the patient. Seven years later, her BCVA had decreased to 0.1 in the right and 0.07 in the left eye concomitant with progressive concentric visual field constriction.

Conclusion:Our patient showed relatively severe visual dysfunction with typical RP fundoscopic findings. The findings associated with RP caused by PDE6A mutations in our patient were similar to those reported by previous studies.
