Minimally Invasive Glaucoma Surgery (MIGS): an updated literature review

ABSTRACT Glaucoma is considered the biggest cause of irreversible blindness in the world and the increase in intraocular pressure is its main risk factor. Usually, the initial therapy for glaucoma consists of reducing IOP through the instillation of topical hypotensive drugs, with antiglaucoma surgeries being normally reserved for cases in which disease control is not clinically achieved. Classically, the surgical treatment of glaucoma is performed using filtering procedures: trabeculectomy; non-penetrating sclerotomy and glaucoma drainage devices. The acronym MIGS (Minimally Invasive Glaucoma Surgery) corresponds to a group of minimally invasive surgical procedures that provide a safer and more predictable pressure reduction when compared to conventional antiglaucoma surgical techniques.

摘要：青光眼被认为是全球范围内不可逆失明的首要病因，眼压（intraocular pressure, IOP）升高是其核心危险因素。临床中，青光眼的初始治疗通常以局部滴用降压药物降低眼压为主，抗青光眼手术则一般仅用于药物无法实现病情临床控制的病例。传统青光眼外科治疗多采用滤过性手术术式，包括小梁切除术、非穿透性巩膜切开术以及青光眼引流装置。微创青光眼手术（Minimally Invasive Glaucoma Surgery，缩写为MIGS）是一类微创手术方案的统称，相较于传统抗青光眼手术技术，该类手术可带来更安全、更具可预测性的眼压降低效果。
