REVIEW
Tyler G Rowsey, Dimitrios Karamichos
Corneal diseases are an extensive cause of blindness worldwide and continue to persist as a challenging public health concern. Recently, various lipid-based therapies have been advocated for the modulation of corneal diseases; however, the number of studies is still very limited. Here we focus on developments and challenges on lipid-based therapies for dry eye disease, diabetic neuropathy, and Fuchs' endothelial corneal dystrophy. All three diseases are highly prevalent conditions and involve corneal stress and inflammation...

This review is focused on the pathophysiology and therapeutic potential of purinergic signalling. A wide range of diseases are considered, including those of the central nervous system, skin, kidney, musculoskeletal, liver gut, lower urinary tract, cardiovascular, airways and reproductive systems, the special senses, infection, diabetes and obesity. Several purinergic drugs are already on the market, including P2Y12 receptor antagonists for stroke and thrombosis, P2Y2 receptor agonists for dry eye, A1 receptor agonists for supraventricular tachycardia...

PURPOSE: To assess the effect of hydroxypropyl methylcellulose (HPMC) 2% to prevent dry eye during phacoemulsification in senile and diabetic patients. METHODS: This prospective interventional case series comprised 60 eyes (44 patients) with age-related cataract scheduled for standardized phacoemulsification surgery. The patients were assigned to receive either balanced saline solution (BSS, 30 eyes) or HPMC 2% (30 eyes) during surgery. Preoperative and postoperative examinations (1, 3, 7 and 30 days) included measurements of automatic noninvasive tear film breakup time (NITBUT), fluorescein staining, Schirmer I test, tear meniscus height, depth and area and subjective symptoms...

"Omics" refers to high-throughput analyses of genes, proteins, or metabolites in a biological system, and is increasingly used for ophthalmic research. These system-based approaches can unravel disease-related processes and are valuable for biomarker discovery. Furthermore, potential therapeutic targets can be identified based on omics results, and targeted follow-up experiments can be designed to gain molecular understanding of the disease and to test new therapies. Here, we review the application of omics techniques in eye diseases, focusing on age-related macular degeneration (AMD), diabetic retinopathy (DR), retinal detachment (RD), myopia, glaucoma, Fuchs' corneal dystrophy (FCD), cataract, keratoconus, and dry eyes...

BACKGROUND To determine the association between serum 25(OH)D and dry eye syndrome (DES) incidence. This study was also designed to determine whether serum 25(OH)D levels were associated with ocular parameter of DES patients. MATERIAL AND METHODS This is a case-control study with 70 DES cases and 70 healthy controls. Clinical data included body mass index (BMI, kg/m²), smoking history, diabetes, and blood pressure. Serum 25(OH)D was chosen as the main parameter and reflected the level of vitamin D. The DES parameters included ocular surface disease index (OSDI) scales, tear film breakup time (TBUT) and Schirmer test I...

BACKGROUND: This paper presents results from the inaugural Scope of Practice Survey of Optometry Australia members conducted in October 2015. The survey gathered information related to confidence in detecting and diagnosing key ocular conditions, grading diabetic retinopathy, prescribing scheduled medicines, access to equipment, confidence using equipment, incidence of patients requiring therapeutic management, referral practices and services provided. METHODS: The survey was developed, piloted, modified and administered to members of Optometry Australia (excluding student and retired members), who had a current email address...

Corneal confocal microscopy (CCM) is an in vivo technique used to study corneal nerve morphology. The largest proportion of nerves innervating the cornea lie within the subbasal nerve plexus, where their morphology is altered by refractive surgery, diabetes and dry eye. The main limitations to clinical use of CCM as a diagnostic tool are the small field of view of CCM images and the lengthy time needed to quantify nerves in collected images. Here, we present a novel, rapid, fully automated technique to mosaic individual CCM images into wide-field maps of corneal nerves...

PURPOSE: To the correlation between plasma osmolarity (Posm) and tear osmolarity (Tosm) in patients (54 patients, 88 eyes) who underwent cataract surgery was evaluated. METHODS: Before cataract surgery, routine pre-operative biochemical tests were performed, and Posm was determined from blood samples. Also, Tosm was measured using the TearLab system, and objective signs including tear break-up time (BUT), fluorescein staining, lissamine green staining, and Schirmer's test were evaluated...

Purpose: To evaluate the efficacy of topical rapamycin in treating autoimmune dacryoadenitis in a mouse model of Sjögren's syndrome. Methods: We developed rapamycin in a poly(ethylene glycol)-distearoyl phosphatidylethanolamine (PEG-DSPE) micelle formulation to maintain solubility. Rapamycin or PEG-DSPE eye drops (vehicle) were administered in a well-established Sjögren's syndrome disease model, the male nonobese diabetic (NOD) mice, twice daily for 12 weeks starting at 8 weeks of age...

REVIEW
Abhirup Mandal, Rohit Bisht, Ilva D Rupenthal, Ashim K Mitra
Effective intraocular drug delivery poses a major challenge due to the presence of various elimination mechanisms and physiological barriers that result in low ocular bioavailability after topical application. Over the past decades, polymeric micelles have emerged as one of the most promising drug delivery platforms for the management of ocular diseases affecting the anterior (dry eye syndrome) and posterior (age-related macular degeneration, diabetic retinopathy and glaucoma) segments of the eye. Promising preclinical efficacy results from both in-vitro and in-vivo animal studies have led to their steady progression through clinical trials...

BACKGROUND: Dry eye syndrome is one of the complaints of diabetic patients. The aim of the present study was to evaluate the tear functions in pregnant women with gestational diabetes mellitus (GDM) using tests: Schirmer, tear break-up time (TBUT), and tear film osmolarity (TFO) tests and the Ocular Surface Disease Index score (OSDI). METHODS: Pregnant women with GDM (Group 1, n=46) and healthy pregnant women (Group 2, n=36) were enrolled. Initially, all participants were asked to answer the OSDI and then they underwent a detailed ophthalmic examination including Schirmer, TBUT, and TFO tests...

Weibao Xiao, Li Sun, Nan Zhang, Wen Ye
Fingolimod is a promising prodrug in attenuating multiple sclerosis and prolonging survival of organ allograft, with many other protective effects. Its mechanism of action is related to the internalization of sphingosine 1-phosphate receptors (S1PRs). Our previous study indicated that fingolimod eyedrops was efficacious in inhibiting ocular inflammation in a dry eye disease (DED) model of non-obese diabetic (NOD) mice. In the current study, we evaluated potential adverse effects of fingolimod eyedrops. Inbred 10-week-old BALB/c mice were randomly divided into four groups, fingolimod-treated groups at three different concentrations (0...
