PURPOSE

The purpose of this study was to evaluate the effectiveness of intravitreal injection of bevacizumab for treatment of central serous chorioretinopathy.

METHODS

In this retrospective case series, six patients (six eyes) with central serous chorioretinopathy were treated with an intravitreal injection of bevacizumab. The outcome measures included visual acuity with Early Treatment Diabetic Retinopathy Study letters, central macular thickness measurement with optical coherence tomography, changes in fluorescein angiography, and indocyanine green angiography.

RESULTS

The mean age of the patients was 42.3 years and the mean follow-up period was 9.0 months (range, 5-12 months). Mean visual acuity +/- standard deviation increased from 40.8 +/- 8.3 Early Treatment Diabetic Retinopathy Study letters at baseline to 49.0 +/- 5.0 Early Treatment Diabetic Retinopathy Study letters at 1 month (P = 0.046) and to 53.3 +/- 5.2 Early Treatment Diabetic Retinopathy Study letters at 3 months (P = 0.028). Mean central macular thickness +/- standard deviation decreased from 331.5 +/- 93.4 microm to 164 +/- 34 microm at 3 months (P = 0.043). Leakage on fluorescein angiography and hyperpermeability on indocyanine green angiography decreased in conjunction with improvement in central macular thickness observed by optical coherence tomography.

CONCLUSION

Intravitreal bevacizumab injections resulted in improved visual acuity and anatomical results for central serous chorioretinopathy.
