Abstract:
Objective:To investigate the correlation between choroidal thickness and sweep OCT angle parameters in primary angle-closure glaucoma(PACG)patients.Methods:72 patients(144 eyes)with PACG who were admitted to Longnan First People's Hospital from February 2022 to February 2024(PACG group)were selected,and 72 volunteers(144 eyes)with normal periodic angle eye examination at the same time were selected(control group).The choroidal thickness of the foveo-temporal side of the eyeball 2500 μm(T2.5),the foveo-naso-temporal side of the eyeball 2500 μm(N2.5)and the choroidal thickness of the macular subfoveal(SFCT)were compared between the two groups,nasal and temporal scanning OCT angle parameters:scleral abruptness(SSA500),angle opening distance(AOD500),angle recess area(ARA500),trabecular meshwork iris area(TISA500)were compared between the two groups.The correlation between choroidal thickness and nasal and temporal scanning OCT angle parameters were analyzed by Pearson analysis.Results:The choroidal thickness of T2.5,N2.5 and SFCT in PACG group were thicker than those in control group(P＜0.05).Nasal and temporal AOD500,TISA500,SSA500 and ARA500 in PACG group were lower than those in control group(P＜0.05).Pearson analysis showed that T2.5,N2.5 and SFCT were negatively correlated with nasal and temporal AOD500,TISA500,SSA500 and ARA500(P＜0.05).Conclusion:Patients with PACG have thick choroid and abnormal parameters of temporal and nasal scan OCT,and there is a significant correlation between choroid thickness and temporal and nasal scan OCT parameters.
