Brian Savoie, Rand Rodgers, Matthew Gorski
Acute dacryoadenitis with abscess formation has been rarely described. We describe four cases that resolved with incision and drainage. This includes a retrospective case series of four patients with radiologically confirmed lacrimal gland abscesses and a review of the reported cases in the literature. Computed tomography showed characteristic rim enhancing collections with central attenuation in all four cases. All patients presented with ptosis, upper eyelid erythema, and severe pain similar to scleritis...

Aqueous tear-deficient dry eye is a multifactorial chronic disorder in which the lacrimal glands fail to produce enough tears to maintain a healthy ocular surface. The existence of lacrimal gland stem/progenitor cells was proposed in several species, yet their origin and characteristics are not very clear. Here, we investigated the presence of resident progenitor cells and their regenerative potential in a rabbit model with lacrimal gland main excretory duct ligation-induced injury. The ligation-injured lacrimal glands temporarily decreased in weight and had impaired tear secretion...

The tear film represents the interface between the eye and the environment. The alteration of the delicate balance that regulates the secretion and distribution of the tear film determines the dry eye (DE) syndrome. Despite having a multifactorial origin, the main risk factors are female gender and advanced age. Likewise, morphological changes in several glands and in the chemical composition of their secretions, such as proteins, mucins, lipidics, aqueous tears, and salinity, are highly relevant factors that maintain a steady ocular surface...

Previously, we have reported that the Secreted Ly6/uPAR related protein-1 (SLURP1) serves an important immunomodulatory function in the ocular surface. Here, we examine the involvement of SLURP1 in regulating corneal angiogenic privilege. Slurp1 expression detected by QPCR, immunoblots and immunofluorescent stain, was significantly decreased in mouse corneas subjected to alkali burn-induced corneal neovascularization (CNV). Addition of exogenous SLURP1 (6XHis-tagged, E. coli expressed and partially purified using Ni-ion columns) significantly suppressed the tumor necrosis factor-α (TNF-α)-stimulated human umbilical cord vascular endothelial cell (HUVEC) tube formation...

The clinical manifestations of pterygium are characterized by rapid growth and postoperative recurrences. We had previously proposed that hypoxia-inducible factor (HIF)-1α recruits progenitor cells during the development and progression of pterygia. Recently, it was reported that various stimuli, including inflammation, could activate HIF-1α even under normoxic conditions. The ocular surface directly faces external environments, and is thus frequently exposed to inflammatory insults. First, we examined the gene expression of HIF-1α, its downstream molecule, vascular endothelial growth factor (VEGF)-A, and VEGF receptor (VEGFR)-2 in corneal and conjunctival cells compared with cultured human umbilical vein endothelial cells...

In the treatment of traumatic injuries, burns, and ulcers of the eye, inadequate epithelial tissue healing remains a major challenge. Wound healing is a complex process involving the temporal and spatial interplay between cells and their extracellular milieu. It can be impaired by a variety of causes including infection, poor circulation, loss of critical cells and/or proteins, and a deficiency in normal neural signaling (e.g. neurotrophic ulcers). Ocular anatomy is particularly vulnerable to lasting morbidity from delayed healing, whether it be scarring or perforation of the cornea, destruction of the conjunctival mucous membrane, or cicatricial changes to the eyelids and surrounding skin...

The cornea must maintain homeostasis, enabling rapid response to injury and microbial insult, to protect the eye from insult and infection. Toll-like receptors (TLRs) are critical to this innate immune response through the recognition and response to pathogens. Myeloid differentiation primary response (MyD88) is a key signaling molecule necessary for Toll-like receptor (TLR) and interleukin-1 receptor (IL-1R)-mediated immune defense and has been shown to be necessary for corneal defense during infection. Here, we examined the intrinsic role of TLR signaling in ocular surface tissues by determining baseline levels of inflammatory mediators, the response to mechanical stimuli, and corneal infection in MyD88-deficient mice (MyD88-/-)...

The ocular surface is comprised of the cornea and conjunctiva, which are structures that not only protect the eye but also enable vision. The corneal epithelium is the most superficial layer of the cornea, and therefore first line of defense against external assaults. Damage to this highly specialized structure could lead to vision loss, making it an important structure to investigate and understand. Here, we conducted a search of the current literature on the mechanisms the corneal epithelium has adapted against three frequent insults: UV-radiation, pathogens, and environmental assaults...

Ocular toxicity as a consequence of chronic pesticide exposure is one of the health hazards caused due to extended exposure to pesticides. The cornea, due to its position as the outer ocular layer and its role in protecting the internal layers of the eye; is gravely affected by this xenobiotic insult to the eye, leading to ocular irritation and damage to normal vision. The deleterious effects of chronic pesticide exposure on the various corneal layers and the ocular risks involved therein, were explored by mimicking the on-field scenario...
