      Optical Coherence Tomography Angiography for Evaluation of Reperfusion following Pterygium Surgery

      Purpose To describe the use of optical coherence tomography angiography (OCTA) to quantitatively monitor the conjunctival graft revascularization after pterygium excision and conjunctival autograft (CAG) transplantation. Design Prospective, interventional case series. Methods Ten patients undergoing pterygium excision and femtosecond laser-assisted CAG transplantation were included. OCTA was performed at 1 week, 1 and 3 months postoperatively at the CAG transplantation site and harvested area. The vessel density at three different depths: conjunctival epithelium or CAG epithelium, conjunctival stroma or CAG stroma, and episclera, was evaluated and quantified. The revascularization rate was assessed and correlated with the postoperative CAG thickness. Results No ...

    2. Intraoperative Optical Coherence Tomography Vault Measurement in Posterior Chamber Phakic Intraocular Lens Implantation

      Intraoperative Optical Coherence Tomography Vault Measurement in Posterior Chamber Phakic Intraocular Lens Implantation

      PURPOSE: To describe the use of intraoperative optical coherence tomography (OCT) vault measurement in 5 cases of posterior chamber phakic intraocular lens (IOL) implantation. METHODS: This case series included 5 eyes in 3 consecutive patients undergoing phakic IOL implantation. RTVue OCT (Optovue, Inc., Fremont, CA) was used to obtain intraoperative vault measurements after pupil constriction. Visante OCT (Carl Zeiss Meditec, Jena, Germany) was used to obtain postoperative vault measurements. RESULTS: Intraoperative vault measurements ranged from 228 to 1,060 µ m. There were no postoperative complications. Postoperative OCT vault measurements ranged from 230 to 670 µ m. CONCLUSIONS: Intraoperative OCT can be ...
