| description | AIM: To observe the clinical characteristics and influence factors of different responses in patients with wet age-related macular degeneration(wARMD)treated with intravitreal conbercept.<p>METHODS: A total of 62 eyes(56 patients)with wet age-related macular degeneration who received intravitreal Conbercept injections(3+PRN)in our hospital from January to September 2018 were retrospectively analyzed. The best-corrected visual acuity(BCVA)and optical coherence tomography(OCT)were performed before and after treatment. Responses were evaluated and grouped according to BCVA after the last injection. 33 cases of 35 eyes with BCVA improvement ≥5 letters were included in the response group. 23 cases with 27 eyes were included in the non-response group. Before and after treatment, BCVA, central retinal thickness(CRT)and related data of the two groups were analyzed.<p>RESULTS: One month after 3 injections, BCVA in the response group increased from 41.83±7.92 letters at baseline to 52.52±10.61 letters(<i>t</i>= -6.883, <i>P</i>=0.02), and BCVA increased from 43.65 ± 10.42 letters at baseline to 44.18 ± 8.47 letters in the non-response group(<i>t</i>=0.471, <i>P</i>=0.684).CRT of the two groups after treatment decreased from the baseline(<i>F</i>=31.47, 27.28, all <i>P</i><0.01). Six months after 3 injections, the proportion of patients with the integrity of the macular fovea ellipsoid in response group(69%)was more than that in the non-responsive group(7%), and the proportion of patients with subretinal fluid(86%)was higher than that without SRF in the response group(44%), the proportion of patients with intraretinal fluid(31%)in the response group was lower than that in the non-response group(81%)(all <i>P</i><0.05), but there was no difference in the proportion of patients with pigment epithelial detachment between the two groups(77% <i>vs</i> 59%, <i>P</i>> 0.05).<p>CONCLUSION: Intravitreal injections of conbercept can effectively reduce the subretinal fluid and retinal fluid in patients with wet age-related macular degeneration, and improve the patient's visual acuity. Patients with the integrity of the outer layer of the retina(especially the ellipsoidal zone)and SRF responded well after treatment, while patients with IRF responded poorly after treatment. |
