Abstract Hematopoietic stem cell transplantation (HSCT) is the most effective cure for hematologic malignancies. Graft-versus-host disease (GVHD) is a major complication following allogeneic HSCT, which significantly affects non-relapse mortality. And ocular manifestations of GVHD are known to occurin 60–90% of patients with chronic GVHD. Although the pathogenesis of ocular GVHD is not clearly known, it is known to progress into inflammation and fibrosis through presentation of antigens on CD4 and CD8 T cells. There is much evidence that the ocular surface and meibomian glands are severely damaged in ocular GVHD patients, and there are few observational studies on the early changes. In this review, we will discuss the various changes in the meibomian glands and ocular surface, and tear dynamics in the early stage following HSCT. These results show that tear film break-up time (TFBUT) decreased and the corneal staining score was significantly higher 2–3 months after HSCT. The upper eyelid and total eyelid meiboscore increased after 3 months following HSCT. The information of the early changes of meibomian glands morphology would be helpful to further examine the pathogenesis of meibomian gland dysfunction.

Contamination of the conjunctiva in association with nasolacrimal duct obstruction is by all accounts a risk factor for infectious endophthalmitis post-cataract surgery. All patients who underwent cataract day surgery routinely received nasolacrimal duct syringing with normal saline at the Wakayama Medical University Hospital, Japan, from 2011 to 2013. The microorganisms isolated from conjunctival swab samples of patients with occluded nasolacrimal ducts and their susceptibility to antibiotics, ...

To analyze ocular surface parameters in patients before hematopoietic stem cell transplantation (HSCT) and to correlate them with hematological characteristics.This is a retrospective analysis of prospectively collected data from 203 patients undergoing HSCT. Demographic data and hematological parameters (disorder type and stage) were collected from clinical charts. Ocular surface parameters (ocular surface disease index; Schirmer test I; tear film break-up time; corneal esthesiometry; and corne...

Cyclosporine-induced sebaceous hyperplasia (SH) is a well-documented entity, occurring in up to 30% of renal transplant patients treated with cyclosporine and has also been reported to occur following heart or hematopoetic stem cell transplantation (HCST). Cyclosporine has a stimulatory effect on undifferentiated sebocytes, resulting in the clinical and histologic findings in these patients. Sebaceous hyperplasia most commonly presents as asymptomatic papules over the face, chest, or groin. Here...

Meibomian gland dysfunction (MGD) is the major cause of evaporative dry eye disease (EDED) and dysfunction is widely thought to mechanistically involve ductal hyperkeratinization, plugging and obstruction. This review re-evaluates the role of hyperkeratinization in MGD based on more recent findings from mouse models. In these studies, eyelids from normal young and old mice or mice exposed to desiccating stress were evaluated by immunofluorescent tomography and 3-dimensional reconstruction to eva...

Meibomian gland loss in ocular GvHD was described as a mechanism contributing to dry eye and severe damage to the ocular surface. Infrared images of upper eyelid meibomian glands from 86 ocular GvHD patients, from 10 patients after allogeneic stem cell transplantation (aSCT) without ocular GvHD, from 32 patients prior to aSCT and from 30 healthy controls were analyzed retrospectively and evaluated using two grading schemes. The upper meibomian gland area (uMGA) was calculated and set in relation...

The International Chronic Ocular GVHD Consensus Group held 4 working meetings to define new diagnostic metrics for chronic ocular graft-versus-host disease (GVHD). After considering the factors currently used to diagnose chronic ocular GVHD, the Consensus Group identified 4 subjective and objective variables to measure in patients following allogeneic hematopoietic stem cell transplantation (HSCT): OSDI, Schirmer's score without anesthesia, corneal staining, and conjunctival injection. Each vari...

Abstract Graft-versus-host disease (GVHD) is a common cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Systemic findings involving the skin, gastrointestinal tract, and liver often overshadow the other manifestations of GVHD. Ocular surface disease remains the most common cause of long-term morbidity in GVHD. Herein, the etiology, pathophysiology, clinical manifestations, and treatment of acute and chronic systemic GVHD are reviewed, with a focus on ocul...

Acquired punctal stenosis is a condition in which the external opening of the lacrimal canaliculus is narrowed or occluded. This condition is a rare cause of symptomatic epiphora, but its incidence may be higher in patients with chronic blepharitis, in those treated with various topical medications, including antihypertensive agents, and especially in patients treated with taxanes for cancer. The purpose of this review is to cover the medical literature, focusing in particular on definition, inc...

Ocular graft-versus-host disease (GVHD) is a major complication after allogeneic hematopoietic stem cell transplantation. Ocular GVHD affects recipients’ visual function and quality of life. Recent advanced research in this area has gradually attracted attention from a wide range of physicians and ophthalmologists. This review highlights the mechanism of immune processes and the molecular mechanism, including several inflammation cascades, pathogenic fibrosis, and stress-induced senescence relat...

Cancer is a global health problem and is one of the leading causes of death worldwide. Pleasingly, the rate of survival has improved and continues in an upward trend mainly due to better diagnosis and treatment modalities. In particular, the development of anticancer drugs including cytotoxic chemotherapy, hormonal agents and targeted therapies have provided the most effective treatment options in combatting cancerous cells. However, the antineoplastic mechanisms of these drugs can also lead to ...

Abstract Purpose To investigate the role of neutrophil extracellular traps (NETs) and NET-associated proteins in the pathogenesis of oGVHD and whether dismantling of NETs with heparin reduces those changes. Methods Ocular surface washings from oGVHD patients and healthy subjects were analyzed. Isolated peripheral blood human neutrophils were stimulated to generate NETs and heparinized NETs. We performed in vitro experiments using cell lines (corneal epithelial, conjunctival fibroblast, meibomian...

: I have reviewed available literature on dry eye related to Sjogren's syndrome (SS), non-Sjogren's syndrome (non-SS), and graft-versus-host disease (GVHD) to examine aqueous tear deficient dry eye as a subtype of dry eye. This section will focus on clinical studies regarding those subtypes of dry eye. I searched the PubMed database from 1990-2017 for discussion of clinical features, diagnostic criteria, and risk factors of SS, non-SS, and GVHD-related dry eye. In addition, therapeutic options f...
