BACKGROUND Many patients with essential blepharospasm also show dry eye signs and symptoms. Botulinum toxin A is an effective treatment for reducing spasms in these patients. In this investigation, the effect of botulinum toxin A injections on tear function and on the morphology of the ocular surface in patients suffering from blepharospasm in combination with a dry eye syndrome was investigate...

PURPOSE The aim of the present study was the in vitro and in vivo evaluation of a novel aqueous formulation based on polymeric micelles for the topical delivery of cyclosporine A for dry eye treatment. METHODS In vitro experiments were carried out on primary rabbit corneal cells, which were characterized by immunocytochemistry using fluorescein-labeled lectin I/isolectin B4 for the endothelia...

PURPOSE To investigate corneal sensitivity to selective mechanical, chemical, heat, and cold stimulation in patients with fibromyalgia (FM). METHODS Twenty patients with FM (18 women, 2 men; 51.9 +/- 2.3 years old) and 18 control subjects (16 women, 2 men; 51.7 +/- 2.4 years) participated voluntarily in the study. Subjective symptoms of ocular dryness were explored and a Schirmer I test was p...

purpose: to evaluate tear film status and refractive conditions during and one month after treatment of acne vulgaris with isotretinoin (accutane). methods: this prospective study was performed on 26 eyes of 13 known cases of acne vulgaris. all cases were referred by a dermatologist and were candidates for low dose isotretinoin (0.5 mg/kg). full anterior and posterior segment examination and ob...

We report a case of glomerulopathy in a 36-year-old Japanese woman with primary Sjögren syndrome (pSS). The first renal biopsy suggested membranous glomerulonephritis. However, repeat biopsy was performed after 16 years because of increased proteinuria, revealing membranoproliferative glomerulonephritis with mesangial deposits, subendothelial deposits, and subepithelial deposits. Immunofluoresc...

IMPORTANCE Botulinum toxin injection for lateral canthal rhytids has been reported to result in dry eye, but its effect on tear film stability and tear production has not been studied thoroughly. OBJECTIVE To investigate the effect of botulinum toxin type A on tear film stability and tear production after treatment of lateral canthal rhytids. DESIGN, SETTING, AND PARTICIPANTS We performed a...

PURPOSE To establish a rat model of neurotrophic keratopathy and to examine the effects of the combination of substance P (SP) and insulin-like growth factor (IGF)-1 on corneal epithelial barrier function and wound healing in this model. METHODS Corneal denervation was achieved by thermocoagulation of the ophthalmic branch of the trigeminal nerve. A modified Schirmer test was performed withou...

OBJECTIVE To characterize the frequency and types of ophthalmic findings in a group of retired racing Greyhounds. MATERIALS AND METHODS Complete ophthalmic examinations of both eyes of 100 retired racing Greyhounds were performed. Anterior segment examinations were performed by slit-lamp biomicroscopy. Tear production was measured by Schirmer tear test. Intraocular pressures were obtained by ...

Three adult patients with Bitot's spots of the conjunctiva were observed in the American Southwest; all were in good health without obvious cause for vitamin A deficiency. Serum vitamin A levels were low normal in two; the third patient was on replacement vitamin A therapy with resultant high serum levels. Serum beta-carotene levels were low in two and normal in one. Schirmer test without anest...

AIMS To evaluate the role of 17-β-oestradiol, oestrone and total testosterone (TT) deficiency in the pathogenesis of severe evaporative dry eye syndrome (DES), investigating the relationship between tear osmolarity, tear film break-up time (TF-BUT), Schirmer test and serum sex hormones in postmenopausal women. METHODS 44 postmenopausal women were recruited for a case-control study: 22 women w...
