    Comparison of Fourier-Domain and Time-Domain Optical Coherence Tomography in the Measurement of Thinnest Corneal Thickness in Keratoconus by Chunxiao Wang, Xueying Xia, Bishan Tian, Shiyou Zhou

    Published 2015-01-01
    “…The TCT value of normal corneas was higher by RTVue-OCT (530.4 ± 19.7 μm) than Visante-OCT (521.5 ± 18.3 μm) (p<0.001). For keratoconus eyes, the TCT was 425.0 ± 58.2 μm and 424.4 ± 55.7 μm (difference being 0.6 ± 10.2 μm, p=0.604). …”

    In Vitro Study on Glucose Utilization Capacity of Bioactive Fractions of Houttuynia cordata in Isolated Rat Hemidiaphragm and Its Major Phytoconstituent by Manish Kumar, Satyendra K. Prasad, Siva Hemalatha

    Published 2016-01-01
    “…The augmentation in glucose uptake by hemidiaphragm in presence of AQ and EA fractions may be attributed to the presence of quercetin, which was found to be 7.1 and 3.2% w/w, respectively, in both the fractions.…”

    Clinical Outcomes of Accelerated Corneal Cross-Linking for Pediatric Keratoconus by Abdelrahman Salman, Taym Darwish, Marwan Ghabra, Obeda Kailani, Hussam Khalil, Rafea Shaaban

    Published 2021-01-01
    “…The mean manifest refraction spherical equivalent value was significantly reduced (−0.59 ± 0.95 D, P=0.0024). While mean flat keratometry and steep keratometry values were not significantly altered (P>0.05 for both), the mean maximum keratometry value was significantly decreased from 56.97 ± 5.24 D preoperatively to 55.84 ± 5.37 D at 24 months postoperatively P=0.003. …”
