Background: Meniscus tear is a common finding in patients with anterior cruciate ligament (ACL) injury and may affectthe natural history of the injury and the outcomes of treatment. In the current study, the characteristics of meniscus tearsin patients who underwent arthroscopic ACL reconstruction were investigated.Methods: The hospital records of 1022 patients were reviewed. ...

A lateral shearing interferometer designed and built for the study of the precorneal tear film topography dynamics and its effect on visual performance is presented. Simple data processing algorithms are discussed and tested on data illustrating different tear topography features: postblink tear undulation, tear breakup, eyelid-produced bumps and ridges, bubbles, and rough precontact lens tear ...

AIM To analyze tears in sterile surgical gloves used by surgeons in the operating theatre of the Trauma and Orthopedic Surgery Department, Copernicus Memorial Hospital, Łódź, Poland. MATERIALS AND METHOD This study analyzes tears in sterile surgical gloves used by surgeons by ICD-9 and ICD-10 codes. 1,404 gloves were collected from 581 surgical procedures. All gloves were tested immediately f...

PURPOSE Extended wear of conventional hydrogel soft contact lenses (SCLs) is associated with adverse ocular responses. Some of these ocular events are thought to result from inadequate tear mixing in the postlens tear film (PoLTF). Therefore, strategies to increase tear mixing may improve the safety of extended-wear SCLs. Recently, it has been suggested that placing fenestrations in soft lenses...

Background: The effect of in vivo implantation on breast implants is important to both physicians and patients, but little information about the in vivo aging process of silicone gel-filled breast implants has appeared in the literature. The effects of the in vivo aging process could affect the durability of breast implants. Objective: The purpose of this study was to investigate changes in the...

Tear exchange beneath a contact lens facilitates ongoing fluid replenishment between the ocular surface and the lens. This exchange is considerably lower during the wear of soft lenses compared with rigid lenses. As a result, the accumulation of tear film debris and metabolic by-products between the cornea and a soft contact lens increases, potentially leading to complications. Lens design inno...

PURPOSE Plasminogen activator activity (PAA) in tears of pregnant women was investigated at various gestation times to assess the availability of plasminogen activator for aiding potential corneal wound healing processes during pregnancy. METHODS PAA was measured by a spectrophotometric method. The analysis used 91 tear samples from pregnant and non-pregnant women, supplemented with 10 additi...

the aim of this study was to evaluate the efficacy of a hyaluronic acid containing eye drop in ameliorating ocular surface pathology and discomfort in canine keratoconjunctivitis sicca (kcs). twenty five dogs with kcs treated with a topical carbomer (ca)-based tear replacement gel were moved to treatment with a hyaluronic acid (ha)-containing tear replacement eye drop. dogs were subject to a fu...

background: ramadan fasting may alter a variety of physiological parameters which by themselves influence ocular system. here, we review the effects of ramadan fasting on the health and function of the eye. materials and methods: literature records in  pubmed/medline, web of science, embase, google scholar, and iran medex databases as well as proceedings of related meetings  from january 1986 t...

PURPOSE To correlate tear fluorescein clearance with interleukin-1alpha (IL-1alpha) concentration and gelatinase B (matrix metalloproteinase [MMP]-9) activity in the tear fluid of patients with ocular rosacea and normal control subjects. METHODS Gelatinase activity was evaluated by gelatin zymography in tear fluid obtained from 13 patients with ocular rosacea (including 1 patient with recurre...
