Retinal pigment epithelium tears after bevacizumab injection.

BACKGROUND

The advent of anti-vascular endothelial growth factor (VEGF) treatment for choroidal neovascularization has become the standard of care for wet age-related macular degeneration (AMD). Among the choices, intravitreal bevacizumab, for off-label use, has gained popularity. Recent attention has been on the complications of anti-VEGF treatment, one of them being a retinal pigment epithelial (RPE) tear. A tear in the RPE is a visually devastating complication, most commonly associated with fibrovascular pigment epithelial detachments (PED) in AMD, and may develop during the course of intravitreal bevacizumab treatment.

CASE REPORT

We report a case of an 85-year-old white man with decreased visual acuities of 20/70 in the right eye (O.D.) and 20/150 in the left eye (O.S.) secondary to dry AMD O.D. and wet AMD with a fibrovascular PED O.S. The patient underwent treatment with an intravitreal bevacizumab injection O.S. Six weeks after the initial injection, the patient returned with further declining vision in the left eye secondary to an RPE tear.

CONCLUSION

Intravitreal bevacizumab has proven to be an effective treatment for choroidal neovascularization and shows a significant improvement of vision for wet AMD patients. However, there are risks associated with the procedure. One of the most visually significant is an RPE tear, which can occur at an incidence rate as high as 17%. Optometrists should be aware of this rare, but serious, complication associated with anti-VEGF treatment for wet AMD.
