Lindsey engendered other legends. Once, when a doctor asked some volunteers to enter a chamber filled with CS tear gas, Lindsey went right along with them and refused to come out. He found that if he could manage to tolerate the first twenty minutes or so, he would became adapted to the irritant effects and could function normally. This profoundly impressed both volunteers and staff. Ordinarily, even highly motivated soldiers would not submit to more than a few minutes - sometimes only seconds - of exposure to the painful effects of CS on eyes and respiratory passages. 

Nondegradable polymers are also useful as matrices for ocular implants. This application requires the polymer to be hydrophilic, to minimize local tissue irritation. Need for ocular implants stems from the challenges posed to conventional ocular medicines (i.e., eye drops) such as rapid dilution, tear washout, poor patient compliance, and limited bioavailability. Ocular implants from hydrophilic polymer matrices that provide localized sustained release may overcome the above limitations. The first polymeric sustained release product to reach the market was Ocusert , a pilocarpin sustained release ocular implant developed by Alza. Ocusert has the drug reservoir as a thin disc of pilocarpine-alginate complex sandwiched between two transparent discs of microporous membrane fabricated from ethylene-vinyl acetate copolymer. The microporous membranes permit the tear fluid to penetrate into the drug reservoir compartment to dissolve pilocarpine from the complex. Pilocarpine molecules are then released at a constant rate of 20 or 40 pg/hr for a four- to seven-day management of glaucoma. 

No Firelight made the Maestro s tears shine like diamonds as he watched the paper bum. You re no thief That was a cleverly set trap, Alfeo. Karagounis was dispensable. Even if the Ten did not already know about him, you had exposed him. So his demon used his death as a powerful charge of evil to break down your normal defenses, like setting off a mine under a castle wall. Your fiend had betrayed you to thechaush s demon, and it managed to open a portal to you, so you were vulnerable. You were bewitched ... 

Volpone has waited for the propitious moment to make his entrance. It is a theatrical axiom that the star reserves for himself the most opportune moment to make his big appearance. As it turns out, Mosca has stage-managed this whole scene with the same genius he manifested in inventing the plot. Voltore introduces Volpone with melodramatic tears in his eyes. When he calls the fox an imposter, he is unaware of the complete accuracy of his statement. Only Mosca, Volpone, and the audience can revel in the roguery of the situation. The hyperbole again increases the irony of the action. 

Contact lenses are attractive formats for fluorescence-based sensing, as they are optically transparent, easily accessible, and are sufficiently inexpensive to be disposable. A handheld device for patients to self-test has been developed to excite and measure fluorescence from lenses (Figure 10.9) and some limited clinical trials have been performed.143 144 However, the efficacy of using tear fluid to manage diabetes...

Contact Lens Fitting and Management Fluorescein staining of the tear film is a major aid in the fitting of rigid gas-permeable contact lenses.After topical application of fluorescein to the eye the tear layer becomes visible, with a characteristic pattern of green fluorescence. Observation of the fluorescein-stained tear film with an ultraviolet light or the cobalt blue filter of the slit lamp allows determination of the fit of the lens. 

KCS is more prevalent in rosacea, so attention to this aspect of management is crucial. The use of artificial tears, lubricating ointments, or topical cyclosporin is often required to ensiu e improvement in symptoms. 

Educating patients about appropriate hygiene and adhering to standard infection control procedures in the office are extremely important aspects of management. Adenoviral infections are contagious, and infected individuals continue to shed virus in tears and from the nasopharynx for approximately 2 weeks. Patients should be educated with regard to transmission of the infection and should be instructed to adopt stringent, droplet, and contact infection control precautions. Direct hand-to-eye contact may result in the transmission of infection. 

In the early stages the management of pterygia usually involves palliative therapy. Patients show significant relief of symptoms with the use of artificial tears and ointments. When these are insufficient, mild steroids, such as... 

Tear duct fibrosis develops in one of six patients with excessive lacrimation from fluorouracil (66). The eversion of the lower eyelid is reversible with conservative management (68) while the tear duct fibrosis may not be (69). Persistent lacrimation has been described in six patients receiving intravenous fluorouracil weekly for 6-10 months (69). Lacrimation persisted in five patients after the withdrawal of fluorouracil, suggesting an irreversible dacryostenosis. Lacrimal duct stenosis has also been reported (70). Bilateral cicatricial ectropion was also reported in a patient after topical administration of fluorouracil for the treatment of multiple facial actinic keratoses (71). If ectropion and tear duct stenosis progress, surgical correction may be required.
