Stevens-Johnson syndrome(SJS)refers to a type of adverse reactions of the skin and mucosa mainly caused by drug allergy, which can be life-threatening in serious cases. For SJS survivors, ocular damage are accepted as the most severe complications. In recent years, because of the extensive research of its genetic susceptibility and immune pathogenesis, varied susceptibility genes which are involved in the ocular complications of SJS have been discovered. However, further efforts are still needed to clarify relevant mechanisms due to the high ethnicity and drug specificity. Ocular lesions of SJS are prone to be neglected in the early stage, and patients often receive ophthalmic treatment after a severe visual loss. Especially in China, the ocular surface of most patients has already been seriously damaged when they went to the ophthalmology department, while existing treatments achieve unsatisfactory results in improving visual acuity. Therefore, recent research progress is reviewed in this article on etiology and treatment of SJS ocular lesions, in order to raise clinicians' awareness of ocular complications, and provide references for the diagnosis and treatment of diseases and research in related fields.
