PURPOSE: To evaluate Bruch's membrane opening - minimum rim width (BMO-MRW) and peripapillary retinal nerve fiber layer thickness (RNFLT) following an acute primary angle-closure attack (APAC).
MATERIALS AND METHODS: Nine consecutive patients with unilateral APAC were included. Patients with a bilateral attack, with signs of glaucomatous optic nerve damage or evidence of a previous APAC in either eye were excluded. Three months after the attack, all eyes underwent BMO-MRW and RNFLT measurements with SDOCT. APAC eyes were compared to the contralateral eyes.
RESULTS: Three months after the attack, mean BMO-MRWs were 281.22 ± 56.88 μm and 313.78 ± 43.48 μm (P = 0.009) and mean RNFLTs were 78 ± 15.36 μm vs 95.78 ± 10.81 μm (P = 0.008) in the APAC and contralateral eyes, respectively. RNFLT and BMO-MRW measurements had a strong positive correlation (R = 0.7436, P = 0.013). APAC eyes had a shorter axial length (21.85 ± 1.21 vs 22 ± 1.07, P = 0.042) and shallower anterior chamber depth (2.29 ± 0.21 vs 2.41 ± 0.12, P = 0.039) than contralateral eyes. IOP at presentation showed a strong negative correlation with both BMO-MRW (R = -0.7669, P = 0.009) and RNFLT measurements (R = -0.7723, P = 0.008).
CONCLUSION: BMO-MRW and RNFLT measurements are significantly reduced 3 months after an APAC when compared to the contralateral eye. IOP at presentation may have an impact on the reduction of these parameters.
