The hiPSC-derived corneal endothelial progenitor-like cell recovers the rabbit model of corneal endothelial dystrophy.

Introduction: Corneal endothelial dysfunction results in cornea opacity, damaging sightedness, and affecting quality of life. A corneal transplant is the current effective intervention. Due to the scarcity of donated cornea, such an unmet medical need requires a novel therapeutic modality.

Peripheral ulcerative keratitis in a patient with granulomatous rosacea.

A 24-year-old woman visited our emergency department due to intermittent dull pain in the right eye, blurred vision, foreign body sensation for 3 weeks, and progressive facial rash with pustules for 3 months. She had a history of recurring skin rash on her face and extremities since early adolescence. Peripheral ulcerative keratitis (PUK) was diagnosed based on slit-lamp examination and corneal topography and then granulomatous rosacea (GR) based on clinical manifestations and skin pathology.

Amniotic membrane transplantation in a patient with impending perforated corneal ulcer caused by : A case report and review of literature.

Background: () is an opportunistic pathogen that can lead to severe ocular infections. In previous reports, penetrating keratoplasty (PK) was usually adopted for the treatment of persistent corneal ulcers. This report describes an unusual case of nonhealing descemetocele caused by treated by antibiotics plus amniotic membrane transplantation (AMT).

Accelerated Corneal Endothelial Cell Loss after Phacoemulsification in Patients with Mildly Low Endothelial Cell Density.

By evaluating preoperative endothelial cell density (ECD), ECD loss after phacoemulsification can be predicted. In this retrospective cross-sectional study, we compared outcomes of phacoemulsification with different levels of preoperative ECD. Three-hundred-and-fifty-three patients aged between 18 and 90 years received phacoemulsification at Chang Gung Memorial Hospital.

Accelerated corneal endothelial cell loss in two patients with granulomatosis with polyangiitis following phacoemulsification.

Background: Generally, the loss rate of human endothelial cells (HCEC) in routine cataract surgery is 8.5%. When the corneal endothelial cells density (ECD) drops, the HCEC may decompensate to keep cornea dehydration which leads to corneal edema.

Clinical Outcomes of Penetrating Keratoplasty and Descemet Stripping Automated Endothelial Keratoplasty in Asian Population with American Corneas.

To determine the comparative efficacy and safety of penetrating keratoplasty PK) and Descemet stripping automated endothelial keratoplasty (DSAEK) in the Asian population receiving imported donor corneas, our single-center retrospective study provides analysis supporting the transition from PK to DSAEK in the Asian population using imported American donor corneas. We analyzed 259 patients with 241 and 57 cases of PK and DSAEK respectively during 2008 to 2017 using imported corneas at Chang Gung Memorial Hospital, Linkou, Taiwan. In terms of long-term graft survival analysis, there was no difference between PK and DSAEK (log-rank = 0.

Optimization of reprogramming culture conditions for the generation of induced pluripotent stem cells from Col1a1 4F2A-Oct4-GFP mice with high efficiency.

A reprogrammable transgenic mouse strain, called Col1a1 4F2A-Oct4-GFP, was bred for the present study. Because the somatic cells of this mouse strain contain only two copies of each Yamanaka factor, these animals are inefficient at producing induced pluripotent stem cells (iPSCs; approx. 0.
