Corneal integrity and transparency are indispensable for good vision. Cornea homeostasis is entirely dependent upon corneal stem cells, which are required for complex wound-healing processes that restore corneal integrity following epithelial damage. Here, we found that leucine-rich repeats and immunoglobulin-like domains 1 (LRIG1) is highly expressed in the human holoclone-type corneal epithel...
A scleral contact lens lies on the sclera, not cornea, which differs from a rigid gas permeable (RGP) lens, and has shown successful clinical outcomes in patients unable to tolerate glasses or RGP lenses because of severely deformed cornea. In addition, forms tear film between cornea that stabilizes ocular surface could be useful therapeutic option. The mini-scleral is option for visual improve...
BACKGROUND Surgical outcome of corneal keloid is largely variable depending on reports, although surgical management is inevitable in visually significant cases. We here report clinical features, histopathological findings, and surgical outcome of four cases of corneal keloid. CASE PRESENTATION Four Korean male patients without a history of corneal trauma or disease were clinically and histol...
Purpose: Contrast sensitivity, the ability to distinguish relative difference in luminance of an object from its surrounding or adjacent objects, is a useful measure visual function. In granular corneal dystrophy type 2 (GCD2), opacity stroma causes deterioration We compared contrast sensitivity GCD2 patients before and after phototherapeutic keratectomy (PTK) evaluate perioperative function th...
purpose: to report the clinical findings and compare the outcomes of different surgical techniques evolved over time in a large series of patients with delayed-onset mustard gas keratitis (mgk). methods: this interventional retrospective case series includes patients with complications of delayed mgk. medical and surgical interventions to address dry eye, limbal ischemia and limbal stem cell de...
Genetic Heterogeneity for Recessively Inherited Congenital Cataract Microcornea with Corneal Opacity
PURPOSE To isolate fibroblast precursors from rabbit corneal stroma using a sphere-forming assay, to engineer corneal stroma with the precursors and gelatin, and to establish the therapeutic application of precursors in a rabbit corneal stroma. METHODS In the in vitro study, a sphere-forming assay was performed to produce precursors from rabbit corneal stroma. Corneal stroma was engineered by...
