OBJECTIVE: To evaluate how closely neuropathic-like ocular pain (NOP) symptoms align with a metric of central sensitisation (ie, the presence of persistent ocular pain after topical anaesthetic placement) in individuals with dry eye (DE) symptoms. DESIGN: Cross-sectional study of 224 individuals with DE symptoms seen in the Miami Veterans Affairs eye clinic. An evaluation was performed consisting of questionnaires regarding DE symptoms, NOP descriptors and evoked pain sensitivity testing on the forehead and forearm, followed by a comprehensive ocular surface examination including corneal mechanical sensitivity testing...

Rationale and key points Eye care is an important aspect of the nursing management of patients who are critically ill. All patients in acute care settings with absent or compromised eye defence mechanisms are at risk of eye complications and ocular surface disease. This article aims to assist nurses to care for the eyes of patients in critical care settings to enable early detection and routine management of ophthalmic issues, thereby avoiding visual compromise on patient discharge from critical care settings...

PURPOSE: Cyclosporine A (Cs) has been used as effective topical therapy for inflammatory dry eye disease since more than a decade. However, due to its lipophilic character, Cs is formulated as emulsions or oily solutions for topical application. This experimental study aimed to test if the use of semifluorinated alkanes (SFAs) as a preservative-free, well-tolerated non-stinging or burning vehicle maintains or even improves the benefits of Cs in the topical therapy of dry-eye disease. METHODS: Desiccating stress was applied to C57BL/6 mice for 14 consecutive days to induce experimental dry-eye...

BACKGROUND: Toric intraocular lens (IOL) implantation can be an effective method for correcting corneal astigmatism in patients with vitreoretinal diseases and cataract. Our purpose is to report the outcome of toric IOL implantation in two cases - a patient with scleral-buckle-induced regular corneal astigmatism and a patient with keratoconus following pars plana vitrectomy. As far as we are aware, there are no reported cases of toric IOL implantation in a vitrectomized eye with keratoconus nor of toric IOL implantation in patients with scleral-buckle-induced regular corneal astigmatism...

BACKGROUND: The study of human lacrimal gland biology and development is limited. Lacrimal gland tissue is damaged or poorly functional in a number of disease states including dry eye disease. Development of cell based therapies for lacrimal gland diseases requires a better understanding of the gene expression and signaling pathways in lacrimal gland. Differential gene expression analysis between lacrimal gland and other embryologically similar tissues may be helpful in furthering our understanding of lacrimal gland development...

BACKGROUND: Creutzfeldt-Jakob disease (CJD) has been accidentally transmitted by contaminated corneal transplants. Eye donors are not ordinarily tested for CJD, in part because an easy test is not available. We propose a relatively simple postmortem procedure to collect brain samples without performing full autopsy and show that a test currently marketed for veterinary diagnosis would offer an effective screening test. METHODS: We selected 6 brains from confirmed cases of human sporadic CJD and sampled each in triplicate (18 specimens), 28 control brains of individuals with non-CJD neurodegenerative diseases and 10 normal brains...

OBJECTIVES: Hormonal changes during oral contraceptive pill (OCP) use may affect central corneal thickness (CCT) values. We aimed to evaluate the impact of OCP use on CCT values in healthy young women. MATERIALS AND METHODS: Fifty women subjects who use OCP for contraception (Group 1) and forty control subjects (Group 2) who do not use OCP were included in this prospective study. None of the patients had any history of systemic or ocular diseases. The CCT values measured by ultrasonic pachymeter (Nidek US-4000 Echoscan, Japan) and the intraocular pressure (IOP) values were measured by noncontact tonometer (Reichert 7 CR Corneal Response Technology, USA) at the time of admission to our clinic...

HSV-1 infections of the cornea range in severity from minor transient discomfort to the blinding disease herpes stromal keratitis, yet most patients experience a single episode of epithelial keratitis followed by re-establishment of a clear cornea. We asked whether a single transient episode of HSV-1 epithelial keratitis causes long-term changes in the corneal microenvironment that influence immune responses to subsequent corneal infection or trauma. We showed that C57BL/6 mouse corneas infected with HSV-1 KOS, which induces transient herpes epithelial keratitis without herpes stromal keratitis sequelae, possessed a significant leukocytic infiltrate composed primarily of CD4(+) T cells and macrophages along with elevated chemokines and cytokines that persisted without loss of corneal clarity (subclinical inflammation)...

Lifitegrast is a novel small molecule integrin antagonist that blocks the binding of intercellular adhesion molecule 1 (ICAM-1) to lymphocyte function-associated antigen 1 (LFA-1). Lifitegrast ophthalmic solution 5% (Xiidra™) was recently approved in the USA for the treatment of dry eye disease. The efficacy of lifitegrast ophthalmic solution 5% was compared with vehicle in a 12-week phase 2 study and three 12-week phase 3 studies (OPUS-1, OPUS-2 and OPUS-3) in patients with dry eye disease. Taken as a whole, results of these trials support the treatment effect of lifitegrast ophthalmic solution 5% in improving a symptom of dry eye disease (i...
