    1. Advances in Imaging Technology of Anterior Segment of the Eye

      Advances in Imaging Technology of Anterior Segment of the Eye

      Advances in imaging technology and computer science have allowed the development of newer assessment of the anterior segment, including Corvis ST, Brillouin microscopy, ultrahigh-resolution optical coherence tomography, and artificial intelligence. They enable accurate and precise assessment of structural and biomechanical alterations associated with anterior segment disorders. This review will focus on these 4 new techniques, and a brief overview of these modalities will be introduced. The authors will also discuss the recent advances in research regarding these techniques and potential application of these techniques in clinical practice. Many studies on these modalities have reported promising results, indicating the potential for ...

    2. Objective Imaging Diagnostics for Dry Eye Disease

      Objective Imaging Diagnostics for Dry Eye Disease

      Traditional diagnostic tests for dry eye disease (DED), such as fluorescein tear film break-up time and the Schirmer test, are often associated with poor reproducibility and reliability, which make the diagnosis, follow-up, and management of the disease challenging. Advances in ocular imaging technology enables objective and reproducible measurement of changes in the ocular surface, tear film, and optical quality associated with DED. In this review, the authors will discuss the application of various imaging techniques, such as, noninvasive tear break-up time, anterior segment optical coherence tomography, in vivo confocal microscopy, meibography, interferometry, aberrometry, thermometry, and tear film imager in DED ...

    3. Optical Coherence Tomography Angiography for Evaluation of Reperfusion following Pterygium Surgery

      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 ...

    4. 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 ...

    5. Applications of Anterior Segment Optical Coherence Tomography in Cornea and Ocular Surface Diseases

      Applications of Anterior Segment Optical Coherence Tomography in Cornea and Ocular Surface Diseases

      Optical coherence tomography (OCT) is a noncontact technology that produces high-resolution cross-sectional images of ocular tissues. Anterior segment OCT (AS-OCT) enables the precise visualization of anterior segment structure; thus, it can be used in various corneal and ocular surface disorders. In this review, the authors will discuss the application of AS-OCT for diagnosis and management of various corneal and ocular surface disorders. Use of AS-OCT for anterior segment surgery and postoperative management will also be discussed. In addition, application of the device for research using human data and animal models will be introduced.

    6. Use of Anterior Segment Optical Coherence Tomography to Predict Corneal Graft Rejection in Small Animal Models

      Use of Anterior Segment Optical Coherence Tomography to Predict Corneal Graft Rejection in Small Animal Models

      Purpose: To correlate the degree of anterior chamber (AC) inflammation and corneal thickness evaluated by anterior segment optical coherence tomography (ASOCT) with corneal graft rejection status and to explore the value of ASOCT in assisting the diagnosis or prediction of graft rejection using a rat penetrating keratoplasty (PK) model. Methods: A total of 40 PKs were performed using Fisher rats (allogeneic groups) and Lewis rats (syngeneic group) as donors and Lewis rats as recipients: isograft control group (n=10), allograft untreated group (n=10), and allograft with 1% prednisolone acetate treatment group (n=20). All the grafts were evaluated for ...
