Valsalva出血性網膜症

A case of Valsalva hemorrhagic retinopathy

　Valsalva手技に伴って網膜出血をきたすValsalva出血性網膜症と考えられた症例を報告した。症例は18歳，男性で，剣道の練習中に竹刀で喉を突かれ，その直後から左眼の視力低下をきたした。初診時，視力は左矯正で0.15であり，検眼鏡的には黄斑部に円形の0.2乳頭径の網膜出血を認めた。出血は受傷後3週でほぼ消退したが，視力は徐々に向上し，受傷後5か月で左矯正視力1.2となった。

An 18-year-old male suffered from blunt trauma to his neck during Japanease sword-art practice. He noticed sudden visual blurring in the left eye immediately after the accident. When seen by us 6 days later, a retinal hemorrhage of 0.2 disc diameter was present in the central fovea. The corrected visual acuity was 0.15. The retinal hemorrhage disappeared after 3 weeks. Full visual recovery set in 5 months later. We diagnosed him as Valsalva hemorrhagic retinopathy.
