To report a case of Purtscher's retinopathy accompanied by serous retinal detachment in a patient with retinitis pigmentosa (RP) who was referred to us for treatment of post-traumatic visual discomfort.

A 36-year-old man with history of RP was referred to us with the chief complaint of bilateral visual discomfort after chest injury from a traffic accident. His corrected visual acuity was 0.3 and 0.6 in the right and left eyes, respectively. Fundus examination revealed findings characteristic of RP in both eyes, along with a lesion in the right eye, which was suspected to be a serous elevation of the macula, as well as suspected exudates near the optic nerves. Optical coherence tomography indicated serous retinal detachment in the right eye, and fluorescein angiography findings were characteristic of RP. Seven days later, the amount of cotton-wool exudate in the right eye had increased and was more distinct than at the initial examination, and retinal hemorrhage was observed. Based on the medical history and specific fundus findings, the patient was diagnosed with Purtscher's retinopathy. One month later, the serous retinal detachment in the right eye had improved, but the vision loss and total anopsia in the right eye persisted.

The concomitant occurrence of RP and Purtscher's retinopathy is very rare. Moreover, the presence of accompanying serous retinal detachment and delayed onset of typical clinical symptoms are not present in typical Purtscher's retinopathy.
