Abstract
Purpose :
The current treatment approaches for Coats’ disease by intravitreal injection of anti- vascular endothelial growth factor (VEGF) agents (Ranibizumab or Conbercept) combined with laser therapy were evaluated for the efficacy during the treatment.
Methods :
32 patients diagnosed with Coats’ disease followed by the treatment with intravitreal anti-VEGF agents and laser therapies at Tianjin Medical University Eye Hospital and Hebei Eye Hospital during July 2012 and January 2017 were reviewed retrospectively. Clinical data were recorded with a minimum follow-up of 6 months. The patients were divided into Ranibizumab-and Conbercept-treated groups, as well as based on age: pediatric and adult groups.
Results :
32 patients were included in this study. The average number of the injections were 2.75± 0.98. Three patients (9%)underwent SRF drainage operation. Laser photocoagulation was conducted on all patients, and the average number of laser were 2.41 ±0. 95. The average follow-up period was 24.38±9.35 months. 18 patients (56%) were stable, 12(38%) patients were improved, 2 patient (6%) showed recurred SRF and exudation. The initial and final BCVA after intravitreal injection of Ranibizumab did not show a significant difference(p=0.07). While BCVA increased after intravitreal injection of Conbercept(p=0.01). The injection and laser durations between Conbercept and Ranibizumab groups did not vary significantly (p=0.11,p=0.38,respectively). 10 patients(67%) in the Ranibizumab-treated group and 7 (50%) in the Conbercept-treated group reached a stable phase, 5(36%) and 7(50%) patients got the vision improved after Ranibizumab-or Conbercept treated, respectively. In pediatric and adult group, the initial and final BCVA differed significantly (p =0.03, p=0.01,respectively).However, the injection numbers was significantly different (p<0.01),while the laser numbers didnot have any significantly difference(p=0.10).
Conclusions :
The intravitreal injection of Ranibizumab or Conbercept had no significant adverse effects and change effective, and appeared to offer visual and anatomic improvement in Coats’ disease.
