PURPOSE To investigate the interaction between corneal stimuli at different positions and tear secretion and to establish relationships between nociceptive stimuli detection thresholds and stimulated tearing. METHODS Using a computerized Belmonte-esthesiometer, mechanical and chemical stimuli, from 0% to 200% of the threshold in 50% steps, were delivered (in random order) to the central and 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...

Patients with markedly decreased or absent tear duct production require the frequent instillation of artificial tear preparations. Through animal experiments, a new method has been developed for the continuous infusion of these solutions. In this procedure, the canalicular system is intubated with fenestrated silastic tubing, which is subcutaneously tunnelled and then attached to a miniaturized...

BACKGROUND The aim was to evaluate the efficacy of periocular intense pulsed light therapy combined with meibomian gland expression for chronic dry eye due to moderate to advanced meibomian gland dysfunction. METHODS This single-institution, open-label prospective study involved 26 participants who received bilateral treatments using a proprietary intense pulsed light device (E > Eye, E-Swin,...

623 Abstract: In this study we investigated the effect of acetylsalicylic acid (ASA) on tear secretion in rats. The animals were anesthetized intraperitoneally (ip) with urethane (1,2g/kg). The treatment was injected subcutaneously (s.c.). Tear samples were collected by folding a 5 mm section of a Schirmer strip over the lower lid margin to absorb tear fluid from the lower conjunctival sac for ...

INTRODUCTION Dry eye is a common disorder affecting a significant percentage of the population. MATERIALS AND METHODS This study is a prospective, hospital-based, case-controlled study conducted between January 2009 and May 2010. Seventy-six pterygium cases and 152 age-and- sex matched controls presenting to the OPD of Manipal Teaching Hospital were included. The TBUT Schirmer's test and basa...

The article analyzes the effectiveness of an integrated approach to treatment meibomian gland dysfunction, preparation eyelids using copyright mechanical eye massager evacuate secretion glands. As a result, we get improvement in condition and ocular surface due restoration lipid layer tear film, increase protective properties film number normally functioning

Purpose The role of cystic fibrosis transmembrane conductance regulator (CFTR) in lacrimal gland (LG) function has only recently received some attention, mainly from our group. In the present study, we investigated the potential changes of LG pathology, tear secretion, ocular surface integrity, and fluid secretion in isolated LG ducts from CFTR knockout (KO) mice. Methods Tear production and ...
