摘　　要：３３５例浅层角膜病变病例的统计分析发现沙眼的构成比最高，其次为外伤性、细菌性、病毒性、干燥性等。放射性、干燥性、暴露性、腺病毒性等病变主要累及角膜中央部；细菌性、病毒性、药物性、角膜接触镜性等主要表现为弥漫或散在性角膜病变；春季卡他性结角膜炎、沙眼等主要累及上方角膜；下睑缘炎及部分干燥性、暴露性等病变可位于下方角膜。长期和／或多药联合所致的药物性角膜上皮损害应引起重视。hree hundred thirty-five cases of superficial punctate keratopathy(SPK)have been analysed statistical-ly.It has revealed that trachoma was the first cause of the SPK,successively followed by trauma,bacteria,virus,xerophthalmia, etc. Radiational,xerophthalmic, exposure,and adenoviral SPK were mainly in thecenter of the cornea.SPK caused by bacteria,virus,medicament,contact lens mainly appeared random ordiffuse.Vernal keratoconjunctivitis and trachoma induced superior SPK. Inferior marginal blepharitis andsome xerophthalmia,exposure SPK attacked inferior cornea. We should pay attention to medicamentosuspunctate corneal epithelial defects caused by using many kinds of drugs and/or using drugs for a longer time.
