人間ドックにおける後極部眼底写真読影の意義

Significance of posterior fundus photography during routine health check-up for adults

　総合健康診断（人間ドック）の際に眼科検査として無散瞳後極部眼底写真撮影を行った7,268例を対象に，その意義を検討した。442例（6.1％）が異常ありと判定された。緑内障疑いが197例（2.7％），網膜出血性病変が48例（O．7％），網膜変性性病変が32例（O．4％）であった。異常ありと判定され精密検査を受けた110例のうち，61例（56％）が眼疾患を有すると診断された。緑内障疑いと判定された症例の49％が緑内障または高眼圧症と診断された。また低眼圧緑内障が原発解放隅角緑内障の約3倍であった。後極部眼底写真読影は，緑内障などの後極部眼底に変化を示す疾患のスクリーニングに有効と考えられた。

We reviewed a series of 7,268 adults who underwent posterior fundus photography without mydriasis during routine health check-up program. By evaluating the fundus photographs, 442 persons, 6.1%, were judged as pathological needing thorough ophthalmological examinations. Glaucoma was suspected in 197 persons, 2.7%, retinal hemorrhage in 48, 0.7%, and retinal degeneration in 32, 0.4% Out of 110 persons who were examined further, 61 persons, 56%, were diagnosed as having ocular diseases. Out of 72 persons who were initially suspected of glaucoma, 35 persons, 49%, were diagnosed as glaucoma or ocular hyperten-sion. The incidence of low tension glaucoma against primary open angle glaucoma was 3 : 1. The current procedure of posterior fundus photography without mydriasis was thus useful in screening ocular diseases including glaucoma.
