ABSTRACT

@#AIM: To investigate the efficacy of anti-inflammatory treatment and anti-vascular endothelial growth factor(VEGF)treatment on different types of macular edema secondary to retinal vein occlusion(RVO-ME).<p>METHODS: The clinical data of RVO-ME patients who were treated in the Department of Ophthalmology, the First Affiliated Hospital of Zhengzhou University from 2019-06/2020-12 were retrospectively collected. A total of 108 cases(108 eyes)of RVO-ME patients were collected, including 52 cases(52 eyes)with cystoid macular edema(CME), 38 cases(38 eyes)with macular edema with serous retinal detachment(SRD), and 18 cases(18 eyes)with diffuse retinal thickening(DRT). Patients with various types of ME were further classified into anti-VEGF group and anti-inflammatory group. The observation metrics such as best corrected visual acuity(BCVA)and foveal thickness(CMT)before and 3mo after surgery were collected and compared in each group.<p>RESULTS: There was no difference in baseline data between the anti-VEGF group and the anti-inflammatory group in all types of ME patients(all P>0.05). Patients with CME in the anti-VEGF group in BCVA, CMT, and the sum of CME diameter after operation were different from that before operation(Z= -4.463, -4.541, -4.541, all P<0.001); the postoperative BCVA, CMT, and the sum of CME diameter in the anti-inflammatory group were significantly different from those before operation(Z= -3.743, -4.345, -4.372, all P<0.001); and there was no difference between the anti-VEGF group and the anti-inflammatory group in the postoperative CMT and the sum of CME diameter(Z= -1.017, -0.968, all P>0.05), but there was a difference in BCVA after operation in two groups(Z= -1.978, P<0.05). SRD patients in the anti-VEGF group had differences in postoperative BCVA, CMT, and SRD heights compared with preoperative ones(Z= -4.111, -4.198, -4.198, all P<0.01); the BCVA, CMT, and SRD height in the anti-inflammatory group after operation were different from those before operation(Z= -3.410, -3.408, -3.408, all P<0.05); and there was no difference in BCVA and CMT between the two groups after operation(Z= -0.857, -1.030, all P>0.05), but the postoperative SRD height in the anti-inflammatory group was significantly lower than that in the anti-VEGF group(Z= -2.117, P<0.05). DRT patients in the anti-VEGF group were significantly different in BCVA and CMT after operation compared with preoperative ones(Z= -2.207, -2.521, all P<0.05), and in the anti-inflammatory group after injection, BCVA and CMT were significantly different from preoperative ones(Z= -2.207, -2.521, all P<0.05). There were differences in BCVA and CMT after injection in the anti-inflammatory group compared with those before operation(Z= -2.207, -2.803, all P<0.05). There was no difference in postoperative BCVA and CMT between the two groups(Z= -0.359, -0.845, all P>0.05). <p>CONCLUSION: Anti-inflammatory and anti-VEGF treatments are effective for all kinds of ME in improving vision and reducing CMT. Anti-VEGF treatment is superior to anti-inflammatory treatment in improving BCVA of CME patients and is inferior to anti-inflammatory in decreasing SRD thickness of SRD patients.
