BACKGROUND Consistency of arthroscopic evaluation and documentation in meniscal tears between investigators is essential to the validity of multicenter studies. A group of experts developed a classification of meniscal tears that may be used internationally. HYPOTHESIS The International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) classification of meniscal te...
Rotator cuff tear is one of the most common shoulder diseases. It is interesting that some rotator cuff tears are symptomatic, whereas others are asymptomatic. Pain is the most common symptom of patients with a tear. Even in patients with an asymptomatic tear, it may become symptomatic with an increase in tear size. Physical examination is extremely important to evaluate the presence, location,...
which either decreases tear production or increases tear evaporation (Figure 1). Increased tear osmolarity is the link between changes in the lacrimal glands and lids, and disease of the ocular surface. Studies of pre-clinical models of lacrimal gland disease and meibomian gland dysfunction show that the ocular surface changes of dry eye disease are dependent upon and proportional to increases ...
PURPOSE OF REVIEW Hyperosmolarity is a central mechanism causing ocular surface inflammation and eye irritation in typical patients suffering from tear dysfunction. Tear composition in dry eyes, or dysfunctional tear syndrome, may destabilize the tear film and cause ocular surface epithelial disease. Increased activity of matrix metalloproteinases (MMPs), especially MMP-9, plays a critical role...
Aim: To develop a reliable and objective non-touch technique for determination of tear volume and tear secretion by means of tear film fluorophotometry. Methods: 10 defined concentrations of sodium fluorescein were given in an artificial chamber and measured by the Fluorotron Master (Coherent Radiation Inc). A calibration line was established and the calibration equation was programmed into the...
Dry eye is highly prevalent and has a significant impact on quality of life. Acupuncture was found to be effective to treat dry eye. However, little was known about the effect of acupuncture on different subtypes of dry eye. The objective of this study was to investigate the applicability of tear meniscus assessment by Fourier-domain optical coherence tomography in the evaluation of acupuncture...
OBJECTIVE To determine the tear production in dogs admitted to an intensive care unit (ICU). DESIGN Prospective observational study from November 2010-September 2011. SETTING Private emergency and referral hospital. ANIMALS Thirty healthy control dogs and 30 dogs hospitalized in an ICU for treatment of systemic illness without previously diagnosed ophthalmic disorders and no recent histor...
