临床医生在诊断虹膜睫状体炎时很重视病史、睫状充血、睫状部压痛以及瞳孔大小和对光反应等局部改变。虹膜炎性肿胀及瞳孔括约肌之反射性痉挛招致瞳孔缩小和反应迟钝。特别要双眼进行比较,虹膜纹理不清和虹膜变色与对侧健眼相比之下更为明显。初期虹膜睫状体炎可能只有轻度睫状充血和角膜后面下方极细小的灰色或灰白色沉着物,如不用裂隙灯显微镜仔细检查,而仅以肉眼观察则有误诊为急性结膜炎的可能。利用直接焦点照射法检查对于极细小的少量角膜后沉着物易被漏掉,而用后部反光照射法将裂隙灯光线的焦点投照在后部不透明的组织上,把显微镜的焦点对准被检查的组织,借后部反回来的光线来观察角膜的改变,容易看到细小的沉着物。所以,在早期诊断上 Clinicians in the diagnosis of iridocyclitis attaches great importance to history, ciliary congestion, ciliary tenderness and pupil size and response to light and other local changes. Iris inflammatory swelling and pupillary sphincter reflex spasm cause pupil shrinkage and unresponsive. In particular, to compare both eyes, iris texture and iris discoloration contralateral eye contrasted more obvious. Initial iridocyclitis may have only mild ciliary congestion and very small gray or grayish-white deposits beneath the cornea, as examined without a slit lamp microscope, and misdiagnosed as acute conjunctivitis only with the naked eye. The use of direct focus irradiation method for a very small amount of corneal posterior deposition easily missed, and the back of the reflective light irradiation slit lamp light focus on the opaque posterior tissue, the microscope focus was Check the organization, by the back of the light back to observe changes in the cornea, easy to see the small sediments. So, in the early diagnosis
