Indirect choroidal neovascularization secondary to a posterior-segment intraocular foreign body - case report
Lin YS; Peng KLBMC Ophthalmology 2020; 20: 161
BACKGROUND: We reported a rare case of indirect choroidal neovascularization (CNV) secondary to a posterior-segment intraocular foreign body (IOFB) that was not located in the area of direct injury but in the fovea. After intravitreal injections (IVIs) of aflibercept, the choroidal neovascularization (CNV) lesion disappeared and vision improved. CASE PRESENTATION: A 26-year-old male patient suffered from a fast-shot metallic IOFB in his right eye. He underwent primary corneal repair, pars plana vitrectomy, IOFB removal and an IVI of antibiotics in the right eye. Two weeks later, cataract surgery was performed on the right eye for traumatic cataract after an episode of acute phacolytic glaucoma. The best-corrected visual acuity (BCVA) of the right eye improved to 20/20 5 months after the first surgery. However, the vision of the right eye worsened suddenly with metamorphopsia 1 year after the first surgery. Color fundus images showed a whitish lesion with faint retinal hemorrhage and surrounding sensory elevation. Fluorescein angiography (FA) revealed a lesion with early- and late-phase severe leakage. Optical coherence tomography (OCT) demonstrated a CNV lesion with surrounding subretinal fluid. The patient received an IVI of aflibercept every 8 weeks for 3 times. Finally, the BCVA of the right eye improved to 20/25. CONCLUSIONS: For rare cases of fovea-spared injury by a metallic IOFB, it is still necessary to pay close attention to the foveal microstructure to avoid possible CNV formation. Treatment with IVIs of anti-VEGF, aflibercept, as early as possible could provide good visual outcomes.
