Optical coherence tomographic angiography (OCTA) has emerged as a rapid, noninvasive imaging modality to visualize the vascular networks in the retina and choroid. Here, we report the clinical findings in a case of primary vasoproliferative retinal tumor (VPRT) observed by the wide-field swept-source OCTA. A 74-year-old male patient with central vision loss and metamorphopsia in his left eye was referred to our hospital. At the first visit, the best-corrected visual acuity was 20/20 OD and 20/40 OS. Fundus examination revealed the presence of the epiretinal membrane and inferotemporal reddish retinal tumor in the left eye. Fluorescein angiography and indocyanine green angiography (ICGA) showed leaky characteristics and sharply defined structure of vessels in the retinal tumor, respectively. The patient was diagnosed with the VPRT with secondary epiretinal membrane and underwent pars plana vitrectomy with internal limiting membrane peeling, retinal photocoagulation, and triple freeze and thaw procedure using cryopexy. Whereas wide-field swept-source OCTA preoperatively depicted the flow signals as distinctive vascular structures similar to ICGA, the tumor color turned out to be ischemic white, and the flow signals detected by wide-field OCTA disappeared after the surgery, indicating that the freezing effect of transscleral cryopexy sufficiently reached the surface of the tumor. In sum, wide-field swept-source OCTA is a useful imaging modality that can be noninvasively and repetitively performed to determine the treatment effect in cases of peripheral retinal tumors such as VPRT. |
