Changes of anterior chamber structure in patients after combined surgery of glaucoma and cataract with viscoelastics injection under the sclera valve / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To evaluate the changes of anterior chamber structure in patients after combined surgery of glaucoma and cataract with viscoelastics injection under the sclera valve by OCT. <p>METHODS: The cataract with acute glaucoma patients who underwent combined surgery of glaucoma and cataract from 2016 to 2018 were enrolled. The patients were divided into the viscoelastics group and the control group. The anterior chamber depth(ACD), the angle opening distance(AOD₅₀₀)and the trabecular iris angle(TIA)were examined to compare the changes of the anterior chamber structure between the two groups. <p>RESULTS: At 1 and 3d after surgery, the ACD(3.82±0.51,3.71±0.63, 3.78±0.33mm), the angle opening distance(AOD₅₀₀ 0.25±0.04, 0.24±0.04, 0.25±0.05mm)and the TIA(25.13°±8.06°, 26.18°±8.06°, 29.25°±6.22°)were statistically different between two groups. There was no significant difference on the ACD, the AOD₅₀₀ and the TIA of the two groups 7d after surgery(<i>P</i><0.05).<p>CONCLUSION: Viscoelastics injection under the sclera valve can deepen the anterior chamber effectively after combined surgery of glaucoma and cataract. It avoids the occurrence of shallow anterior chamber in the early postoperation and maintains the opening of anterior chamber.
