Intraocular pressure (IOP) is a delicate biometric – even a small improvement heightens the risk of developing glaucoma, and risk solely would increase with age. We also know that charges of lid malposition improve with age, so it’s more likely that a patient requiring surgery for lid malposition is vulnerable to glaucoma. However, how does surgery on the lower-lid have an effect on the pressure of the eye?
Clinical researchers from the UK have investigated the impact of lower-lid surgery with the lateral tarsal strip (LTS) technique on IOP – discovering that the surgery was related to a statistically important increase in IOP, each instantly and, in some patients, three months after surgery.
Lead authors for this work, Harpreet Kaur and Sarj Athwal declare that influence of this finding “a protracted interval of increased intraocular pressure as a result of lid tightening might lead to poor control of glaucoma, leading to disease development.” They go on to explain the functional principle behind findings “Think about holding an inflated seashore ball in your arms. If you happen to squeeze it and apply pressure on one end, you already know that the external pressure has an impact on the interior pressure from the way the form of the ball turns into distorted. We wanted to search out out if the same factor occurs to the eyeball whenever you tighten the eyelid towards it by assessing whether or not the intraocular pressure changes.”
This study has emphasized the significance of contemplating a patient’s glaucoma when considering surgical options – it’s possible that surgical procedures might have detrimental results on glaucoma risk and disease development. Harpreet and Sarj spotlight that “this is related not simply to ophthalmologists. However, all clinicians performing lid surgery for useful or aesthetic causes reminiscent of plastic and maxillofacial surgeons.”
An important consideration of this paper is that the study was designed to take a look at lower-lid post-surgery modifications in IOP for healthy eyes. The authors point out that whereas that is vital and helpful research, “there’s a need for additional analysis to evaluate and quantify the risk in patients with pre-existing glaucoma.”
