1986年7月より1987年6月までに大阪警察病院眼科を受診した網膜静脈閉塞症患者194例のうち,両眼に発症していたものは13例(6.7%)であった.両眼発症例の平均年齢は65.9歳で男女比は4:9であった.両眼に中心静脈閉塞症を発症したもの1例,両眼に分枝静脈閉塞症を発症したもの11例,分枝静脈閉塞症に続き対側眼に分枝静脈閉塞症,中心静脈閉塞症の順に発症したものが1例であった.対側眼に発症するまでの期間は,平均3.9年であった.分枝静脈閉塞症の両眼発症例のうち,病変が対側眼の黄斑に及ぶものが5例であった.これら13症例は全て高血圧症を有していた.対側眼への網膜静脈閉塞症の発症の予防には,血圧の厳重なコントロールが,またその早期発見,早期治療のためには,定期的な経過観察が重要であると考えられた.
We observed 194 cases with retinal vein occlusion during a 12-month period through June 1987. We detected retinal vein occlusion in the fellow eye also in 13 cases (6.7%).
In the bilateral 13 cases, the age averaged 65.9-year-old. There were 9 females and 4 males. Branch retinal vein occlusion (BRVO) was present bilaterally in 11 cases. Central retinal vein occlu-sion (CRVO) was present in one. One casemanifested BRVO in one eye and CRVO in the other. The time lag between the onset of retinal vein occlusion in both eyes averaged 3.9 years.
In 12 cases with BRVO in the contralateral eye, the macula was spared from BRVO in 7 cases. All the 13 cases in the present series were hyper-tensive, while the incidence of systemic hyperten-sion was 65% in the whole 194 cases. Cases with retinal vein occlusion with hypertension need par-ticular care and close follow up because of the potential risk in the fellow eye.
