一、药源性眼睑、结膜及角膜病:眼药水剂及膏剂均可因其pH值、渗透压的不稳定和介质的性质而引起眼表面非特异性刺激性炎症。表现为急、慢性充血、流泪及结膜滤泡增生等。有些药物(如地卡因、环胞苷、二性霉素B等)对角膜上皮及内皮细胞有直接损伤作用,严重者可致上皮剥脱和实质水肿。这些直接损伤作用与药物的浓度、剂量和次数有关。例如,过去我们测量眼压和取角膜异物前用1%地卡因滴眼三次,角膜反
First, the drug-derived eyelids, conjunctival and corneal diseases: eye drops and ointment can be due to its pH, the instability of the osmotic pressure and the nature of the medium caused by eye non-specific irritating inflammation. The performance of acute, chronic congestion, tearing and conjunctival follicular hyperplasia. Some drugs (such as cocaine, cytidine, amphotericin B, etc.) on the corneal epithelial cells and endothelial cells have a direct role in injury, severe cases can cause epithelial exfoliation and substantial edema. These direct damage effects and drug concentration, dose and frequency related. For example, in the past we measured intraocular pressure and corneal foreign bodies before taking 3% 1% tetracycline eye drops, corneal
