Ioannis S Dimopoulos, Alina Radziwon, Chris D St Laurent, Ian M MacDonald
PURPOSE OF REVIEW: Although much has been written to define the phenotype and genotype of choroideremia (CHM), research continues to provide new insights that serve to better understand its pathogenesis and the directions for potential experimental therapies. RECENT FINDINGS: We would like to highlight new findings, expanding the type of disease-causing mutations to include mutations in the CHM promoter that will dramatically influence gene expression. Information derived from careful phenotyping of patients points increasingly to the central role of the retinal pigment epithelium as the key cell layer affected in the degenerative process...

PURPOSE OF REVIEW: Refractive surgery procedures have been performed on children since the early 1980s. This article will review this history as well as current thoughts on treating children with large refractive errors. RECENT FINDINGS: Pediatric refractive surgery has developed slowly as very few children fit the criteria for treatment. For this reason, practice patterns are varied and publications are rare. Publications in recent years have focused on intraocular procedures over laser refractive surgery...

Kyeong Hwan Kim, Shahzad I Mian
PURPOSE OF REVIEW: A state of limbal stem cell deficiency (LSCD) can be secondary to a number of etiologies, resulting in either a reduction in the total number of limbal stem cells or an abnormality in stem cell function. Initially, the epithelium becomes irregular and hazy; however, this condition may progress to persistent corneal epithelial defects, stromal scarring, ulceration, and even perforation. Since LSCD secondary to a variety of etiologies may be reversible, and various factors are prognostic of disease progression, timely diagnosis is important...

#11
Virender S Sangwan, John A H Sharp
PURPOSE OF REVIEW: Simple limbal epithelial transplant (SLET) is a technique for addressing limbal stem cell deficiency. Limbal tissue from a donor eye, typically the patient's fellow healthy eye, is transplanted onto an amniotic membrane attached to the surface of the diseased eye. SLET was developed to address limitations of other techniques. Specifically, the technical difficulty of ex-vivo expansion of cells required in some techniques and the larger amount of valuable limbal tissue harvested in techniques not relying on ex-vivo expansion...

C Maya Tong, Lamis Baydoun, Gerrit R J Melles
PURPOSE OF REVIEW: Descemet membrane endothelial keratoplasty (DMEK) has become a first-line treatment in corneal endothelial diseases because of its exceptional clinical outcomes and low complication rates. Because of its improved refractive predictability, DMEK is now also considered for managing cases with endothelial decompensation following previous refractive procedures, or in combination with those. This article reviews the clinical outcomes in these cases and discusses the possibility of refractive interventions following DMEK...

PURPOSE OF REVIEW: Refractive surgery has stimulated considerable progress in corneal and anterior segment imaging, and optical characterization of the eye. From front surface corneal topography, we evolved to three-dimensional corneal tomography with limbus to limbus characterization of the front and back corneal surfaces and pachymetric mapping. Corneal anatomical evaluation has further evolved to layered or segmental tomography with the ability to characterize corneal epithelial thickness profile and the elevation of stromal front surface...

PURPOSE OF REVIEW: The aim of this review is to describe the underlying mechanisms of corneal epithelial homeostasis in addition to illustrating the vital role of the limbal epithelial stem cells (LESCs) and the limbal niche in epithelial regeneration and wound healing. RECENT FINDINGS: The shedded corneal epithelial cells are constantly replenished by the LESCs which give rise to epithelial cells that proliferate, differentiate, and migrate centripetally. While some recent studies have proposed that epithelial stem cells may also be present in the central cornea, the predominant location for the stem cells is the limbus...

PURPOSE OF REVIEW: Keratolimbal allograft (KLAL) transplants limbal tissue attached to a corneoscleral carrier from a cadaveric donor to deliver a large number of stem cells to the recipient. The present article will provide a review of KLAL focusing on the recent literature. RECENT FINDINGS: Recent findings pertain to tissue selection, immunosuppression and adverse event profiles, and postoperative complications (particularly related to immunologic rejection). SUMMARY: KLAL permits the treatment of limbal stem cell deficiency eyes when there is no available living-related or autograft tissue with minimal risk of irreversible toxicity from modern systemic immunosuppression...
