A 47-year-old Chinese man with autosomal dominant retinitis pigmentosa had peripheral visual loss in the right eye for 3 days. Visual acuity was 20/40. Retinal pigmentation between the equator and the arcades was present with an attached, normal-appearing macula (Figure). There was a ring of retinal detachment peripheral to the pigmentation. A small anterior U-shaped tear was present at the 12-o’clock position. Pars plana vitrectomy with encirclage and 20% perfluorohexane resulted in retinal reattachment with improvement of visual acuity to 20/30.
