A Simple and Easy Method Using Rigid Endoscope to Detect Iridocorneal and Keratolenticular Adhesions in Peters' Anomaly

Case Reports in Ophthalmology, 2013
Peters' anomaly is characterized by a central corneal opacity with corresponding defects in the posterior stroma, Descemet's membrane, and endothelium. We present 2 cases that showed corneal opacity when examined by topical endoscopic imaging (TEI). Case

Corneal Opacity in LCAT Disease [PDF]

Cornea, 1992
Deficiency of lecithin:cholesterol acyltransferase, LCAT disease, is one of the dyslipoproteinemias with characteristic lipid deposits in the cornea. The present report documents the clinicopathologic abnormalities of one case in which a full-thickness corneal specimen was obtained at the time of corneal transplantation.

Identification of the regulatory circuit governing corneal epithelial fate determination and disease.

PLoS Biology, 2023
The transparent corneal epithelium in the eye is maintained through the homeostasis regulated by limbal stem cells (LSCs), while the nontransparent epidermis relies on epidermal keratinocytes for renewal.

Axenfeld-Rieger syndrome: a novel histopathologic finding associated with corneal abnormalities

BMC Ophthalmology, 2022
Background Axenfeld-Rieger syndrome (ARS) is a rare kind of anterior segment dysgenesis (ASD). The most common ocular features of ARS are posterior embryotoxon and iris hypoplasia, while some patients may manifest as corneal opacity and edema.

Vimentin Knockdown Decreases Corneal Opacity [PDF]

Investigative Opthalmology & Visual Science, 2014
Wound induced corneal fibrosis can lead to permanent visual impairment. Keratocyte activation and differentiation play a key role in fibrosis, and vimentin, a major structural type III intermediate filament, is a required component of this process. The purpose of our study was to develop a nonviral therapeutic strategy for treating corneal fibrosis in ...
