Use of intravitreal triamcinolone and bevacizumab in Coats' disease with central macular edema.

BACKGROUND

Intravitreal application of triamcinolone and bevacizumab in Coats' disease with macular edema to improve visual outcome.

METHODS

Testing of best-corrected visual acuity (BCVA), ophthalmoscopy, optical coherence tomography, fluorescein angiography, 30° perimetry, and full-field electroretinography were performed at initial and follow-up visits. Medical treatment consisted of intravitreal injection of 1.25 mg bevazicumab and 1.25 mg triamcinolone, followed by intravitreal injections of 1.25 mg bevazicumab at weeks 4 and 10. Follow-up was 87 weeks.

RESULTS

Perimetric results, including a temporal absolute scotoma and reduced electroretinographic amplitudes (photopic and scotopic conditions), did not significantly change during the follow-up, but foveal retinal thickness decreased from 505 μm to 212 μm, and BCVA increased from 0.3 at baseline to 1.25 and remained stable during subsequent follow-up.

CONCLUSIONS

Combined intravitreal treatment with bevacizumab and triamcinolone resulted in significant decrease of central retinal thickness and improved visual acuity in this case report. Severe local or systemic side-effects were not observed.
