A new screening sign—the triple hump (TH)—worked well to predict the impact of laser peripheral iridotomy (LPI) on eyes with primary angle-closure suspect (PACS) patients, according to a cross-sectional study involving 84 individuals. Researchers noted that TH may be useful in planning treatment for such patients.
All participants were PACS patients. Investigators imaged patients prior to LPI, looking for a TH sign, described as “the characteristic configuration formed by the angulations between the crystalline lens's central anterior surface and both sides of the iris pigment epithelium.” They then compared intraocular pressure (IOP) in those with and without the TH sign. Among the results:
