本研究采用美国Ｈｕｍｐｈｅｒｙ视野计，视野６０°范围内８０点的阈值程序，观测了３０例３０眼良性眶瘤病人的视网膜光敏感度（ＲＳ），并与正常健眼比较，结果表明：①９０％的接触球后壁的眶瘤病人有相应部位及ＲＳ下降。②实性肿瘤和囊性肿瘤均可引起局部ＲＳ下降，与对照组比较，差异有非常显著的意义。③实性肿瘤可引起全网膜平均ＲＳ下降，而囊性肿瘤对全网膜平均ＲＳ的影响不大。
In this study, we used the American Humphery perimetry with a threshold of 80 points in the field of view, and observed the retinal light sensitivity (RS) of 30 patients with 30 benign tumors. Compared with normal eyes, the results showed that: 190% Patients with tumors that touched the posterior wall of the ball had corresponding sites and decreased RS. Both solid tumors and cystic tumors can cause local RS decline. Compared with the control group, the difference has a very significant significance. (3) Solid tumors can cause a decrease in mean retinal RS, while cystic tumors have little effect on mean retinal RS.
