光刺激恢復試驗之臨床應用

Clinical Evaluation of Photostress Recovery Test

摘要


本報告利用1963年Severin所提出之光刺激恢復試驗法,對正常眼100眼,黃斑部病變27眼及視神經病變15眼進行研究。結果黃斑部病變之光刺激恢復時間延長,而視神經病變之恢復時間則正常。藉此光刺激恢復試驗可作為黃斑部與視神經病變兩者之簡單鑑別輔助方法。且可得知眼底鏡觀察之網膜形態變化與實際網膜機能間之定量關係。

This Report studied the photostress recovery test, suggested by Severin in 1967. The retina is exposed to a quantitated light (an ordinary penligth held 2-3 cm from the eye for 10 sec.) and there covery time is precisely measured. In this report, three groups were studied. The results of recovery time in this study were: Normal group 5.1±1.3 sec, maculopathy group 87±35 sec and the optic nerve disease group 6.2±2.7 sec. In eyes with maculopathy the recovery time was prolonged. Prolonged recovery time was not observed in patients who had optic nerve diseases. Photostress recovery test is a simple and valuable maneuver, which may resolve the dilemma by 1) distinguishing between macular diseases and optic neuropathy, 2) establishing a semi-quantitative relationship between ophthalmoscopic findings and functional capability of retina.
