研究目的:

双眼急性虹膜透照缺损综合征(Bilateral Acute Iris Transillumination, BAIT)是一种以双眼急性、弥漫性虹膜色素上皮脱失、虹膜透照缺损和一过性高眼压为主要特征的眼科疾病。近年来,临床实践中观察到部分患者在因呼吸道感染后,和/或常规使用抗感染药物后,出现了符合BAIT诊断的临床表现。 尽管BAIT的确切发病率尚不明确,但其急性发作的特性、显著的虹膜结构改变以及可能导致的持续性畏光、视物模糊和潜在的青光眼风险,对患者的视觉质量和生活质量均构成严重威胁。 目前,BAIT的具体病因仍不完全清楚,推测可能与病毒感染(作为呼吸道感染的常见病因),也不能除外药物的的特异性反应或毒性作用等多种因素相关。探讨这些因素在BAIT发病中的作用,对于指导临床合理用药、早期识别和干预BAIT至关重要。  

Objectives of Study:

Bilateral Acute Iris Transillumination (BAIT) is an ophthalmic condition characterized primarily by acute, diffuse loss of iris pigment epithelium, iris transillumination defects, and transient intraocular hypertension in both eyes. In recent years, clinical practice has observed a subset of patients presenting with clinical manifestations consistent with BAIT following respiratory tract infections and/or the routine administration of anti-infective medications. Although the exact incidence of BAIT remains undetermined, its characteristics—including acute onset, significant iris structural alterations, and the potential for persistent photophobia, blurred vision, and secondary glaucoma risk—pose a severe threat to patients' visual quality and overall quality of life. Currently, the specific etiology of BAIT is not fully understood; it is hypothesized to be associated with various factors, such as viral infections (a common cause of respiratory illness), or idiosyncratic drug reactions and toxicities. Investigating the roles of these factors in the pathogenesis of BAIT is of critical importance for guiding rational drug use in clinical practice and facilitating early recognition and intervention.
