由于眼睛独特的解剖学特点,不少全身性疾病常可在视网膜、脉络膜、角膜、结膜、眼肌、神经及其它眼部组织中反映出来,认识这些相应的变化常有助于全身性疾患的诊断。眼作为人体内部的重要观察窗,具有十分重要的意义,而且此观察窗不仅局限于眼底,而且角膜、结膜、泪腺,眼肌、虹膜,睫状体等也均有此种作用。同时就眼科领域而言,通过对眼部病变和全身性疾患间广泛联系的研究,也可增进对某些眼科疾患的认识。本文阐述的内容不包括众所周知的资料,如高血压、糖尿病的眼底病变等。一、眼部病变和耳鼻咽喉、口腔疾患(一)Cogan综合征具有三大症状:(1)非梅毒性角膜实质炎;(2)前庭神经症状;(3)两侧性高度感音性重听。本病以年青者为多,60岁以上者很 Due to the unique anatomic features of the eye, many systemic diseases are often reflected in the retina, choroid, cornea, conjunctiva, oculomotor, nerves and other ocular tissues. Recognizing these corresponding changes often contributes to systemic disorders diagnosis. The eye as an important observation window inside the human body is very important, and this observation window is not limited to the fundus, but also the cornea, conjunctiva, lacrimal gland, eye muscle, iris, ciliary body and so on. At the same time, in the field of ophthalmology, the understanding of certain ophthalmic conditions can also be enhanced through extensive research into the relationship between ocular lesions and systemic disorders. This article does not cover the well-known information, such as hypertension, diabetic retinopathy and so on. First, ocular lesions and otolaryngology, oral disorders (A) Cogan syndrome has three major symptoms: (1) non-syphilitic corneal psoriasis; (2) vestibular nerve symptoms; (3) both sides of the highly sensitive sound weight listen. The disease is young, more than 60 years old
