Abstract

Purpose: To identify the anterior segment parameters associated to acute primary angle closure. Patients and Methods: Case-control study in 58 primary angle closure suspect eyes (PACS, control group) and in 19 acute primary angle closure fellow eyes, case group. All subjects underwent SL OCT imaging in a dark room. Results: The SS, ACD and ACV measures were significantly smaller in case group than in control group (p = 0.011; p < 0.001; p = 0.007 respectively); while the IT was significantly greater (at 500 and 750 μm) (p = 0.038 and p = 0.050). The difference between quadrants were statistically significant only for control group (p = 0.001; p = 0.003; p = 0.009; p = 0.018; p = 0.002 and p < 0.001) for IS, ACA₅₀₀, AOD₅₀₀, AOD₇₅₀, TISA₅₀₀, and TISA₇₅₀ respectively. Conclusion: Acute primary angle closure is associated to the smaller anterior segment dimensions and the thicker iris compared to PACS.
