| 본문 : Purpose To describe anatomical and functional results of intravitreal dexamethasone implant for the treatment of macular edema (ME) associated .with idiopathic macular telangiectasia (IMT) type 1
Methods Retrospective case series of two male patients with IMT type 1. Two eyes of two patients who had cystoid macular edema (CME) associated with IMT type 1 were treated repeatedly with intravitreal bevacizumab, but CME persisted. These eyes were treated with intravitreal dexamethasone implant. Best corrected visual acuity, optical coherence tomography, and fluorescein angiography were monitored over the follow up period.
Results Intravitreal dexamethasone implant injection accompanied with proper focal laser photocoagulation resulted in improvement of CME in IMT type 1 which was recalcitrant to intravitreal injection of bevacizumab. No severe adverse effects were noted over follow up period. Although CME recurred after a certain amount of time, intravitreal dexamethasone implant has been effective in treating recurred CME.
Conclusions Intravitreal dexamethasone implant appears to be safe and effective for the treatment of macular edema associated with IMT type 1, which does not respond to intravitreal injection of anti-vascular endothelial growth factor agents. |
