【正文】 hen a slitlamp beam is directed, obliquely to the plane of the iris, into the anterior chamber. It occurs as a result of increased protein content, and usually inflammatory cells, in the aqueous humour. Visual impairment depends on the intensity of the flare. It is a sign of intraocular inflammation. KP: fibrous deposits on the posterior surface of the cornea, usually associated with uveitis. Called also KPs. 糖尿病視網(wǎng)膜眼底改變。分期標(biāo)準(zhǔn)和黃斑水腫的分級(jí) p317（表）。 近視、遠(yuǎn)視、散光的概念（英）。 Myopia is the medical term for nearsightedness. People with myopia see objects more clearly when they are close to the eye, while distant objects appear blurred or fuzzy. Reading and closeup work may be clear, but distance vision is blurry. Hyperopia (farsightedness) is the condition of the eye where ining rays of light reach the retina before they converge into a focused image. Astigmatism is the result of an inability of the cornea to properly focus an image onto the retina. The result is a blurred image. 視網(wǎng)膜脫離的概念（英）、脫離的位置。 Retinal detachment is movement of the transparent sensory part of the retina away from the outer pigmented layer of the retina. In other words, the moving away of the retina from the outer wall of the eyeball. 孔源性、牽拉性、滲出性 神經(jīng)上皮全層 眼外傷：交感性眼炎的概念 。電光性眼炎（紫外線）。急性化學(xué)傷的急診處理（非送醫(yī)院）。 指一眼眼球穿通傷或內(nèi)眼手術(shù)后的雙側(cè)肉芽腫性葡萄膜炎。外傷或手術(shù)眼為誘發(fā)眼、另一眼為交感眼 又稱(chēng)雪盲。電焊、高原、雪地及水面反光可導(dǎo)致。紫外線對(duì)組織 有光化學(xué)作用，使蛋白質(zhì)凝固變性，角膜上皮壞死脫落。照射后 38 小時(shí)發(fā)作，有強(qiáng)烈異物感，刺痛、畏光流淚及瞼痙攣。 沖洗眼球，爭(zhēng)分奪秒 就地取材 至少 30 分鐘 翻眼瞼、轉(zhuǎn)眼球、暴露穹窿部 沖洗
