Abstract Purpose:To report a case of retinitis pigmentosa who showed mutation in the gene RDH12.

Case:We observed this female patient initially at the age of 25 years during routine ophthalmological examinations.

Findings and Clinical Course:Best corrected visual acuity(BCVA)was 1.2 in the right eye and 1.0 in the left. The fundus showed diffuse retinal degeneration and macular atrophy. Perimetry showed scotoma sparing the macula. Single flash electroretinogram(ERG)showed slight decrease in amplitude. Multifocal ERG was almost absent in the center. Gene analysis showed compound heterozygous mutations(c.52delG/c.59C>T)or RDH12. The patient has been followed up until she is now at the age of 43. BCVA is currently 0.1 in the right eye and 0.7 in the left. The scotoma has increased in size. ERG has decreased in amplitude.

Conclusion:This case of retinitis pigmentosa showed RDH12 mutation, which is rare in the Japanese. Fundus findings were similar to those reported in literature. Visual acuity was better in this patient.
