Elevated vascular endothelial growth factor levels in Coats disease: rapid response to pegaptanib sodium

1Department of Ophthalmology, Stanford University, 300 Pasteur Drive, Room A-157, Stanford, CA 94305, USA.
Purpose:
The purpose was to report a case of elevated intraocular vascular endothelial growth factor (VEGF) levels in a 2-year-old boy with stage 4 Coats disease.
Design:
Interventional case report.
Methods:
A 2-year-old boy with severe Coats disease and complex retinal detachment refractory to surgical intervention underwent two injections of intravitreal pegaptanib sodium in his right eye 8 weeks apart.
Results:
After intravitreal injection there was a marked reduction in VEGF (908 to 167 pg/ml) levels and improvement of exudation, hemorrhage, and nearly complete reattachment of his retina within 3 weeks of treatment. The patient remains stable 6 months post-treatment.
Conclusions:
Coats disease may have a component of dysregulation of VEGF-mediated angiogenesis as evidenced by elevated levels in this patient.
