    Corneal injuries can occur secondary to traumatic, chemical, inflammatory, metabolic, autoimmune, and iatrogenic causes. Ocular infection may frequently occur concurrent to corneal injury; however, antimicrobial agents are ...
  • Characterization of Tear Immunoglobulins in a Small-Cohort of Keratoconus Patients 

    McKay, Tina B.; Serjersen, Henrik; Hjortdal, Jesper; Zieske, James D.; Karamichos, Dimitrios; 0000-0002-8761-3824 (Karamichos, Dimitrios) (Springer Nature, 2020-06-10)
    Keratoconus (KC) is classically considered a non-inflammatory condition caused by central corneal thinning that leads to astigmatism and reduced visual acuity. Previous studies have identified increased systemic levels of ...
  • Nerve influence on the metabolism of type I and type II diabetic corneal stroma: an in vitro study 

    Whelchel, Amy E.; Nicholas, Sarah E.; Ma, Jian-Xing; Karamichos, Dimitrios; 0000-0002-8761-3824 (Karamichos, Dimitrios) (Springer Nature, 2021-07-01)
    Corneal innervation plays a major role in the pathobiology of diabetic corneal disease. However, innervation impact has mainly been investigated in the context of diabetic epitheliopathy and wound healing. Further studies ...
  • The Role of Estriol and Estrone in Keratoconic Stromal Sex Hormone Receptors 

    Escandon, Paulina; Nicholas, Sarah E.; Cunningham, Rebecca L.; Murphy, David A.; Riaz, Kamran M.; Karamichos, Dimitrios; 0000-0002-8761-3824 (Karamichos, Dimitrios); 0000-0001-5984-5516 (Cunningham, Rebecca) (MDPI, 2022-01-14)
    Keratoconus (KC) is a progressive corneal thinning disease that manifests in puberty and worsens during pregnancy. KC onset and progression are attributed to diverse factors that include: environmental, genetics, and ...
  • Quercetin Decreases Corneal Haze In Vivo and Influences Gene Expression of TGF-Beta Mediators In Vitro 

    McKay, Tina B.; Kivanany, Pourisika B.; Nicholas, Sarah E.; Nag, Okhil K.; Elliott, Michael H.; Petroll, W. Matthew; Karamichos, Dimitrios; 0000-0002-8761-3824 (Karamichos, Dimitrios) (MDPI, 2022-07-07)
    We have previously reported the flavonoid, quercetin, as a metabolic regulator and inhibitor of myofibroblast differentiation in vitro. Our current study evaluated the effects of topical application of quercetin on corneal ...
  • FAK Inhibition Attenuates Corneal Fibroblast Differentiation In Vitro 

    Yeung, Vincent; Sriram, Sriniwas; Tran, Jennifer A.; Guo, Xiaoqing; Hutcheon, Audrey E. K.; Zieske, James D.; Karamichos, Dimitrios; Ciolino, Joseph B.; 0000-0002-8761-3824 (Karamichos, Dimitrios) (MDPI, 2021-11-12)
    Corneal fibrosis (or scarring) occurs in response to ocular trauma or infection, and by reducing corneal transparency, it can lead to visual impairment and blindness. Studies highlight important roles for transforming ...
  • Sex Hormones, Growth Hormone, and the Cornea
