OBJECTIVES To investigate tear ferning (TF) test repeatability between sessions by observing changes in the tear fern pattern during the day. METHODS Twenty-three healthy young adults (15 men and 8 women), ranging in age from 20 to 32 years (mean ± SD: 22.9 ± 3.3 years) without signs or symptoms of dry eye disease, ocular disease, or contact lens wear were enrolled in the study. Schirmer I, t...

Dry eye has gained recognition as a public health problem given its high prevalence, morbidity and cost implications. Although dry eye is common and affects patients' quality of life, only one medication, cyclosporine 0.05% emulsion, has been approved by the US FDA for its treatment. In this review, we summarize the basic science and clinical data regarding the use of cyclosporine in the treatm...

OBJECTIVES To evaluate tear levels of neuromediators in patients with dry eye disease and to identify statistical correlations with the clinical findings. METHODS Nineteen patients with dry eye disease (Sjögren syndrome, n = 5 patients; non-Sjögren syndrome, n = 10; and ocular cicatricial pemphigoid, n = 4) and 12 healthy volunteers were enrolled. The eyes of all participants were evaluated b...

Objectives. To evaluate the effects of microincision cataract surgery on dry eye-associated symptoms and signs. Methods. This prospective study included 40 eyes of 32 patients. Microincision cataract surgery was performed to eyes through 2.2 mm superior clear corneal incision. Dry eye-associated symptom scoring, corneal sensitivity test, Schirmer 1 test, tear break-up time (tBUT) were measured ...

Purpose. An open-label pilot study of virgin coconut oil (VCO) was conducted to determine the safety of the agent as ocular rewetting eye drops on rabbits. Methods. Efficacy of the VCO was assessed by measuring NIBUT, anterior eye assessment, corneal staining, pH, and Schirmer value before instillation and at 30 min, 60 min, and two weeks after instillation. Friedman test was used to analyse an...

purpose: to evaluate the prevalence and risk factors of dry eye in the patients referred to an eye clinic in birjand, iran. methods: this cross sectional descriptive-analytical study consisted of 600 patients who were referred to the eye clinic of birjand, iran between september 2010 and september 2011. they were given a simple questionnaire about the risk factors of dry eye including the demog...

purpose: to evaluate and compare tear secretion and tear film instability following laser in situ keratomileusis (lasik) and laser assisted subepithelial keratectomy (lasek). methods: in a randomized clinical trial, 30 eyes of 15 patients underwent lasik and 30 eyes of 15 patients underwent lasek to correct myopia. tear secretion and tear film instability were tested preoperatively, 2 and 6 wee...

BACKGROUD This study aimed to investigate the protective effect of intraoperative used hydroxypropyl methylcellulose (HPMC 2%) on the ocular surface after cataract surgery. METHODS A total of 149 eyes (149 patients) diagnosed with age-related cataract, age 69.19 ± 9.74 years, were enrolled in this prospective, parallel-design, continuous, randomised controlled study. Patients were randomly as...

OBJECTIVE To investigate the discrepancy between patient-reported symptoms and measured clinical findings and influencing factors in dry eye (DE). SETTING A population-based, cross-sectional study was performed in July-August 2007 in northeast China. The study was performed on populations originating from two rural districts that are respectively located approximately 377 and 177 km from our ...
