Optical coherence tomography angiography in quiescent choroidal neovascularization associated with choroidal nevus: 5 years follow-up.

PURPOSE: To report a case of quiescent choroidal neovascularization (CNV) associated with choroidal nevus using optical coherence tomography angiography (OCTA) during 5 years follow-up.

METHODS

Observational case report.

RESULTS

A 53-year old woman was referred our department with diagnosis of choroidal nevus. At 1 year follow-up, fundus autofluorescence revealed hyper/hypoautofluorescent area, infrared image showed hyperreflective area and enhanced depth imaging OCT presented a shallow pigment epithelium detachment without exudation or hemorrhage. Fluorescein angiography and indocyanine green angiography suspected the presence of CNV. Finally, OCTA confirmed a quiescent CNV with an increased flow area of the vascular lesion without any changes in best-corrected visual acuity. At 20 months and 5 years follow-up, the CNV remained quiescent showing no clinical activity on structural SD-OCT and no changes in CNV morphology on OCTA.

CONCLUSION

This case shows the features of quiescent CNV secondary to choroidal nevus after long-term follow-up. OCTA represents a valid imaging technique that allows to identify the CNV and to monitor its progression over time.
