Corneal and conjunctival epithelial stem cells are responsible for the homeostasis and regeneration of the ocular surface epithelium. Corneal epithelial stem cells reside in the basal region of the limbus, while the conjunctival forniceal region appears to be the site that is enriched in conjunctival stem cells. Ocular surface disease arising from limbal stem cell deficiency is characterised by...

PURPOSE To describe the clinical features and outcomes of corneal melt associated with Boston type I keratoprosthesis (KPro) implantation. METHODS Medical records of patients who experienced corneal melt following KPro implantation were reviewed retrospectively. RESULTS Sixty-six adult patients had KPro implantation from January 2004 to November 2010. Six patients had an underlying inflamma...

In pharmaceutical companies and research institutes, many toxicity tests are performed with laboratory animals. This study was performed to produce reference data for eye toxicity tests and to investigate the ophthalmic diseases of 408 ICR mice and 119 BALB/c mice, which are commonly used as subjects in toxicity tests. The experimental animals without clinical disorders were selected regardless...

The term ocular surface disorders indicate a close relationship between the conjunctival and corneal epithelium in many corneal and external diseases. The human amniotic membrane has a thick basement membrane and an avascular stromal matrix and its first ophthalmic use was reported by deRoth for conjunctival surface reconstruction. It was subsequently used for different ophthalmic reasons. Amni...

In the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. Acute corneal pain was induced by the local application of hypertonic saline (5 M NaCl) on the corneal surface, and the number of eye wipes was then counted for 30 s. Subcutaneous (s...

PURPOSE To report a case of hypoplastic trigeminal nerve associated with corneal epithelial disorders that were successfully treated with peptides derived from substance P and insulin-like growth factor-1 (IGF-1). CASE REPORT A 16-month-old boy was referred for treatment of a persistent corneal epithelial defect on his left eye. Magnetic resonance imaging revealed the apparent absence of the ...

This article discusses corneal cross-linking (CXL) and how it transitioned from a modality for treating corneal ectatic disorders to an inventive means of treating infectious keratitis. Initially, CXL was successfully developed to halt the progression of ectatic diseases such as keratoconus, using the standard Dresden protocol. Later, indications were extended to treat iatrogenic ectasia develo...

Administration of topical rebamipide improves the ocular surface in dry eye. We consecutively studied seven eyes in seven cases (three males and four females) with mild lagophthalmos (three cases after eyelid surgery, two cases of incomplete facial nerve palsy, and two cases of senile ectropion) during the treatment of corneal disorders with rebamipide eye drops four times daily for 2 weeks. Th...

Rebamipide was initially developed and approved for use in treating gastric ulcers and lesions associated with gastritis. Discovery of its ability to increase gastric mucin led to investigations of its effect on ocular surface mucin and the subsequent development for use in dry eye patients. Investigations have confirmed that rebamipide increases corneal and conjunctival mucin-like substances a...
