Laser-induced choroidal neovascularization detected on optical coherence tomography angiography in patients with diabetic retinopathy

PURPOSE: To report two cases of laser-induced choroidal neovascularization (CNV) using swept source optical coherence tomography (SS-OCTA) imaging in patients with proliferative diabetic retinopathy. OBSERVATIONS: Two patients developed CNV adjacent to laser scars, and these neovascular lesions were detected on SS-OCTA imaging. Historically, both patients had subretinal fluid associated with these lesions. Visual acuity for both patients was 20/25 in the affected eyes. Both patients were observed over multiple years with stable CNV and visual acuity. CONCLUSIONS AND IMPORTANCE: SS-OCTA was able to detect laser-induced CNV in a rapid and non-invasive manner. When there is no foveal involvement and excellent visual acuity, we recommend close observation since the CNV may not progress.
