Abstract
Purpose: In this study, we aimed to evaluate and compare the visual acuity, macular volume, central macular thickness, change in number of intravitreal ranibizumab injections with micropulse laser applications after loading dose of antiVEGF to DME patients.Study Design: Retrospective study Methods: This study was carried out on 97 patients (45 ranibizumab and 52 micropuls grid laser + ranibizumab) with diabetic macular edema patients who were followed in the Retina Unit. At the control visit after three loading ranibizumab injections administered once a month, micropuls grid laser was applied to one group and ranibizumab injection was continued PRN to both groups for an average of 9.27 ± 2.42 months and central macular thickness, macular volume and visual acuity were recorded. Results: There was no significant difference between the groups in terms of gender, smoking and systemic diseases, initial central macular thickness, macular volume and visual acuity measurements (p> 0.05). Central macular thickness, macular volume and visual acuity values measured at the last follow-up of the patients were not significantly different between the groups (p> 0.05). The mean post-treatment injection requirement was 4.19 ± 1.01 for the ranibizumab with micropuls laser group and 5.53 ± 1.14 for the ranibizumab group. In the group treated with micropuls laser, statistically less number of intravitreal ranibizumab injections were needed (p <0.001). Conclusion: Micropulse laser treatment after initial loading doses reduces the need for antiVEGF injections. Studies with the participation of more patients may help in the selection of treatment methods by comparing micropulse laser combined with different injection protocols.
