Background/purpose: To document by optical coherence tomography angiography, the onset of a choroidal neovascularization (CNV) secondary to traumatic choroidal rupture and describe its changes after an intravitreal injection of bevacizumab.
Methods: Case report.
Results: A 20-year-old woman presented referring vision loss after a blunt ocular trauma in her left eye. The patient underwent a complete ophthalmic examination. Best-corrected visual acuity was 20/200. Fundus examination, fluorescein angiography, indocyanine green angiography, and optical coherence tomography displayed a choroidal rupture with no evidence of CNV. Optical coherence tomography angiography showed the choroidal rupture as a line of choriocapillaris rarefaction because of the mechanical damage. Six months later, best-corrected visual acuity decreased to 20/300; optical coherence tomography angiography displayed the growth of a CNV, characterized by a tangled vascular network. After one intravitreal injection of bevacizumab, optical coherence tomography angiography documented a contraction of the CNV.
Conclusion: Optical coherence tomography angiography is a useful imaging technique for the diagnosis and follow-up of patients with choroidal ruptures. Anti-vascular endothelial growth factor agents represent an effective therapy for the treatment of CNVs secondary to this affection.
