Abstract Objective: To investigate the effect of conjunctival sutureless vitrectomy (23GTVS) on macular function and morphology in patients with complicated rhegmatogenous retinal detachment (RD). Methods: 104 patients with complex conjunctival retinal detachment according to treatment mode was divided into control group (n=52) and the treatment group (n=52), the control group conventional treatment, the experimental group treatment with 23 GTVS. Then operation result, the vision, intraocular pressure, corneal dispersion and corneal curvature before and after surgery, macular function and form, and complications occurred in both group were compared. Results: Effective rate of treatment group was significantly higher than the control group 92.30% vs 76.92%, the difference was statistically significant (P<0.05). After surgery, visual acuity in the treatment group was significantly higher than in the control group (P<0.05). The corneal astigmatism and corneal curvature of the control group increased after surgery, and the corneal astigmatism and corneal curvature of the treatment group did not change. The intraocular pressure in both group was no difference statistically significant (P<0.05). The rate of neuroedema, submacular hydrops and retinal epithelial thickness in the treatment group were lower than the control group 3.84% vs 15.38%, 7.69% vs 23.07%, (152.45±18.11) vs (162.21±20.23)μm (P<0.05). The incidence of complications in the treatment group was lower than that in the control group 9.62% vs 25.00%, and the difference was statistically significant (P<0.05). Conclusion: The application of 23GTVS in complex rhegmatogenous retinal detachment is effective, and has little effect on macular function and morphology.
