Tracer N, et al. - Researchers intended to determine if there is an association between pretreatment corneal hysteresis (CH) and the magnitude of intraocular pressure (IOP) and medication burden reduction following microinvasive glaucoma surgery (MIGS). The sample consisted of 57 patients (84 eyes) with CH measurements who had trabecular meshwork MIGS in a glaucoma practice in New York City with follow-up visits at 3–6 and 9–12 months. According to this retrospective chart review, the lowest and middle CH tertiles experienced significantly reduced mean IOP at 3–6-month follow-ups, while the highest tertile did not. An inverse association was found between pretreatment CH and the magnitude of IOP reduction following surgery. In patients with lower CH who undergo MIGS, there is also evidence of an increased need for repeat surgery or other intervention.
