    1. Application of Keratograph and Fourier-Domain Optical Coherence Tomography in Measurements of Tear Meniscus Height

      Application of Keratograph and Fourier-Domain Optical Coherence Tomography in Measurements of Tear Meniscus Height

      To compare the interoperator repeatability of tear meniscus height (TMH) measurements obtained with a keratograph and Fourier-domain optical coherence tomography (FD-OCT) and to assess the agreement between the methods.Forty-seven eyes with DED and 41 healthy eyes were analyzed using the Schirmer test I and tear breakup time test (TBUT). The TMH was measured three times with each device. The repeatability of measurements was assessed by within-subject standard deviation (Sw), repeatability (2.77 Sw), coefficient of variation (CoV) and intraclass correlation coefficient (ICC). Efficacy in detecting DED was evaluated in terms of the area under the curve (AUC). The TMHs ...

    2. Changes in Retinal Vasculature and Thickness after Small Incision Lenticule Extraction with Optical Coherence Tomography Angiography

      Changes in Retinal Vasculature and Thickness after Small Incision Lenticule Extraction with Optical Coherence Tomography Angiography

      Purpose . To evaluate the changes in retinal vessel density and thickness after small incision lenticule extraction (SMILE) with optical coherence tomography angiography (OCTA) in myopic patients. Methods . In this prospective study, SMILE surgeries were done in 46 eyes of 24 patients with spherical equivalent (SE) more than −6.0 diopters ( D ). Retinal vessel density and thickness at the macula and optic nerve were recorded with OCTA before and 1 day, 2 weeks, and 1 month after surgery. Intraocular pressure (IOP), uncorrected distance visual acuity (UDVA), and refraction were taken at the same time. Results . The superficial retinal vessel density and ...

    3. Observation of anterior chamber volume after cataract surgery with swept-source optical coherence tomography

      Observation of anterior chamber volume after cataract surgery with swept-source optical coherence tomography

      Purpose To investigate the changes in the anterior chamber volume (ACV) with swept-source optical coherence tomography (SS-OCT) after cataract surgery and the factors that influence these ACV changes. Methods This was a prospective cohort study. Fifty-one patients who underwent cataract surgery were enrolled. Their ACV, anterior chamber depth, and angle widths were measured with SS-OCT before and 1 day, 1 week, and 1 month after surgery. The associations between the changes in ACV and posterior vitreous detachment (PVD) and axial length (AXL) were determined. Results Compared with the preoperative volume, ACV increased significantly at all three time points after surgery ...

    4. Histopathologic and Optical Coherence Tomography Observation After Descemet’s Stripping Endothelial Keratoplasty in Rabbits

      Histopathologic and Optical Coherence Tomography Observation After Descemet’s Stripping Endothelial Keratoplasty in Rabbits

      Objectives: To study the histopathologic and optical coherence tomography changes after Descemet’s Stripping Endothelial Keratoplasty in rabbits. Materials and Methods: Descemet’s Stripping Endothelial Keratoplasty was performed in 14 rabbit eyes and descemetorhexis was performed in 10 rabbits, as control. Histopathologic examination and anterior-segment optical coherence tomography were conducted in the Descemet’s Stripping Endothelial Keratoplasty group at 1, 2, 4, and 8 weeks. For the control group, histopathologic examination was performed before surgery and at 1, 2, 4, and 8 weeks after surgery. Results: In the Descemet’s Stripping Endothelial Keratoplasty group, corneas cleared completely within 2 weeks ...
