Purpose. The cornea is protected by apical hydrophilic transmembrane mucins and tears. In pathologic states the mucin barrier is disrupted, creating potential for meibomian lipids to adhere more strongly. Undisplaced lipids create an unwettable surface. The hypothesis that pathologic ocular surfaces alter lipid binding and the ability of tear proteins to remove lipids was tested. Methods. Corne...

Background: The symptoms of rotator cuff tear vary and may even be absent. Thus, the symptoms cannot be explained solely by the presence of rotator cuff tear, and other factors are thought to be involved. Because the rotator cuff comes in contact with the coracoacromial ligament, the elasticity of the ligament may be a factor of the symptoms. The purpose of this study was to clarify the elastic...

PURPOSE The primary healthcare setting is well placed for health screening. Tear fluid composition gives valuable information about the eye and systemic health, and there is now significant interest in the potential application of tears as a tool for health screening; however, the acceptability of tear collection in the primary healthcare setting as compared with other methods of human sample c...

PURPOSE To evaluate the correlation between changes in tear osmolarity, symptoms, and corneal fluorescein staining in patients with dry eye disease (DED). DESIGN Retrospective, clinic-based cohort study. METHODS In this single-institution study, we reviewed the charts of 186 patients with DED from whom we had data on tear osmolarity, symptoms, and corneal fluorescein staining from 2 separat...

BACKGROUND Tear conversion followed by repair and trans-tendon techniques have been widely used for partial-thickness rotator cuff tears. Both of them showed favorable results with regard to the management of articular-sided partial-thickness rotator cuff tears (PTRCTs) of more than 50% thickness. However, controversy continues with the best management. This study aims to compare the clinical o...

PURPOSE We investigated whether the tear interferometric pattern was able to identify differences in tear film kinetics among clinical subtypes of dry eye. METHODS A total of 138 eyes of 76 subjects (38 men and 38 women; mean age ± SD, 61.6 ± 16.2 years) with or without dry eye who visited Itoh Clinic from May to August 2015 were enrolled in a cross-sectional study. Clinical diagnosis of dry ...

RATIONALE Dry eye is the most prevalent condition seen by the ophthalmologist, in particular in elderly. The identification of new common risk factors (computer use and contact lens wear) extends the disease among the young people. The early diagnosis of dry eye is essential, but difficult, because the biochemical changes in tear film usually occur before any detectable signs. Due its advantage...

BACKGROUND Although term and preterm infants have the capacity to secrete tears, the relative contribution of basal and reflex secretion of tears has not been previously assessed together in a prospective study. This information potentially has practical clinical importance. OBJECTIVES To measure basal and reflex tear secretion in preterm (30-37 weeks after conception) and term (38-42 weeks) ...

abstract  background: rotator cuff tear is one of the most common causes of shoulder  complaints in the elderly. based on the severity and patient's condition, a variety of  methods applies to manage the tear and surgery is an important method, which could  be done by open or arthroscopic technique. the current study aimed to investigate  and report short-term results of arthroscopic repair of ...

BACKGROUND Structural characteristics of rotator cuff tears are used in surgical decision making. However, data on the association of tear size with patient-reported pain and function are sparse. PURPOSE To assess the association of tear size, fatty infiltration, and muscle atrophy with shoulder pain/function in patients with cuff tears undergoing operative and nonoperative treatment. STUDY...
