Liu YC, et al. - Via this prospective, interventional case series, researchers focused on the use of optical coherence tomography angiography (OCTA) as a tool to quantitatively monitor the conjunctival graft revascularization following pterygium excision and conjunctival autograft (CAG) transplantation. This study included ten patients undergoing pterygium excision and femtosecond laser-assisted CAG transplantation. At the CAG transplantation site and harvested area, they performed OCTA at 1 week, 1 and 3 months after the operation. They noted that at the CAG and underlying episcleral levels, the vessel regrowth density was 9.6 ± 2.6 % and 11.1 ± 2.8 % between 1 week and 1 month, and was 9.8 ± 1.8 % and 11.9 ± 1.9 % between 1 and 3 months, respectively. For the quantitative and serial assessment of vascularization or revascularization of conjunctiva, conjunctival graft and episclera, OCTA was viewed as a promising tool that subsequently assists in the detection of diseases as well as in treatment monitoring. Postoperative graft deswelling was predicted by the graft revascularization rate.
