The purpose of the investigation was to ascertain the prevalence of dry eye in new outpatients.
A total of 2127 consecutive new outpatients seen in eight Japanese centers from April 1992 to January 1993 underwent comprehensive examinations, including double vital staining and measurement of tear film break-up time, basal tear secretion, and tear clearance. Dry eye was diagnosed if patients had abnormalities of both the tear film and the ocular surface.
Three hundred fifty-nine patients (17%) had dry eye. There was no seasonal pattern for dry eye. The condition was significantly more common in Tokyo than in suburban areas (P < 0.01). The prevalence of dry eye in visual display terminal (VDT) users and contact lens (CL) wearers was significantly higher than in non-VDT users and non-CL wearers (P < 0.05 and P < 0.02, respectively).
Our findings suggest that dry eye is one of the most common ocular disorders encountered by physicians. Furthermore, if patients use VDTs or wear CLs, the likelihood of dry eye occurring is higher.
本调查的目的是确定新门诊患者中干眼症的患病率。
1992年4月至1993年1月期间，在日本八个中心连续就诊的2127名新门诊患者接受了全面检查，包括双重活体染色以及泪膜破裂时间、基础泪液分泌和泪液清除率的测量。如果患者的泪膜和眼表均存在异常，则诊断为干眼症。
359名患者（17%）患有干眼症。干眼症无季节性规律。该疾病在东京比在郊区更为常见（P < 0.01）。视觉显示终端（VDT）使用者和隐形眼镜（CL）佩戴者中干眼症的患病率显著高于非VDT使用者和非CL佩戴者（分别为P < 0.05和P < 0.02）。
我们的研究结果表明，干眼症是医生遇到的最常见眼部疾病之一。此外，如果患者使用VDT或佩戴CL，发生干眼症的可能性更高。
