Find a Job Post a Job. Dry-eye disease is well-recognized as a complex, chronic disease that needs chronic therapy. Superimposed on the intricate landscape of oxidative processes, immunological priming, autoimmunity and inflammatory responses are bouts of acute distress brought on by a constellation of extrinsic and intrinsic factors.
Dry-eye-associated discomfort typically waxes and wanes, based on behavior and environment, as well as diurnal and seasonal biorhythms. Dry-eye subjects also use behavioral modification to optimize comfort and visual function.
Nevertheless, a few times a year, dry-eye subjects can fall off the wagon: This is reckless behavior for a dry-eye subject who, like a Flying Wallenda, has to climb gingerly back up on the high wire after falling off. Non-environmental factors can also bring about an acute attack of dry eye.
We need to ask questions: Did the patient have a recent bout of the flu, a gastrointestinal virus, a fever or episodes of vomiting that may have led to dehydration? Alternatively, is the patient experiencing the onset of menopause, which may have exacerbated a previously milder type disease?
The introduction of new medications, such as an antihistamine, or a new antidepressant or antihypertensive therapy may also be responsible for acute worsening of dry eye. These acute episodes require not only stepping up the maintenance therapy, but also additional pulses of more robust therapeutic options to bring the patient back from the precipice.
When patients begin to suffer from acute dry eye, environmental factors often play a role. An airplane trip alone can be enough to bring on an acute episode of the disease. Innate protective blink mechanisms are overwhelmed by these acute challenges, and normal blink patterns are therefore altered, resulting in compromised visual function that is perceptible to the patient. These are signs that the discomfort is not only environmental, but also endogenous in origin. There is occasionally scleritis, and there is profuse rose bengal and fluorescein staining.
What has occurred is acute damage juxtaposed on the baseline chronic inflammatory state of dry eye. The body responds to this damage with a wound-healing process that is remarkably the same in all tissues: This reparative process is impaired in the dry-eye patient due to a dysfunctional tear film in which the balance of tear constituents such as mucins and lipids is disrupted, 2 a situation that can prolong the reparative process and delay the biological cleanup to the point that it lasts weeks in the dry-eye patient instead of hours or days as in a normal subject.
Most research in the past decade on dry-eye disease points to inflammatory processes at its origin. As with all inflammation, there are chronic and acute pathways that converge and diverge with different signals, but all must begin with an initiating, immunologically priming event. The most challenging aspect of dry-eye research has been to pull apart these threads and try to identify which cell or pathway may be the initial instigating player. By the time the patient is bothered enough to go to the doctor, his or her clinical dry-eye disease is usually in its chronic stages and the continuous cycles of tear film instability are causing mounting inflammation.
However, in the case of a dry-eye attack or exacerbation, the clinician has a chance to observe the disease in its acute, early stage. Understanding what happens at the inception of dry eye can give us greater insight on how best to manage acute exacerbations of the disease. This nomenclature is based on the primary cytokine secreted by each cell population: However, even after days, the corneal staining never returned to normal, demonstrating that chronic inflammation continued even months after the initial day exposure trigger.
After the adverse exposure had ceased, only IL remained elevated. This IL response was associated with lymphangiogenesis, or the growth of lymph vessels in and around the cornea, a key event to priming the region for more antigen presenting cells and a richer immune response. If instead, T cells from mice in the acute phase were transferred, only slightly more severe disease was seen compared to normals. In both cornea and conjunctiva, chronic dry-eye mice were found to have the highest quantity of effector memory T cells, which contain twice the amount of IL as in other T cells.
These dominoes can be chemokines, such as CXCL9, , and CXCR3, which recruit cells to the cornea and conjunctiva, amplifying the original signal sent out by cytokines. These also are found increased in tear fluid of dry-eye patients and might be directly related to keratitis and staining. In dry eye, these processes lead to a dysfunctional lacrimal functional unit, which is how all of the components that ultimately participate in forming and preserving an optimal tear film are denoted.
These include lacrimal and meibomian glands, goblet cells, the cornea and conjunctiva the lids, and the sensory and motor nerves that communicate among all of these elements. A breakdown in any of these will lead to altered rheological properties and hyperosmolarity of tears, decreased corneal sensitivity and alterations in blink, and imperfectly anchored or dissolved mucins, all of which culminate in either aqueous-deficient or evaporative dry-eye disease. Conversely, a classic case of aqueous deficiency may be complicated by the onset of meibomian gland dysfunction.
If the patient is only on tear supplementation, stepping up tear production with continuous Restasis therapy cyclosporine emulsion 0.
However, addition of a single pulse of steroid therapy for squelching these acute inflammatory episodes of dry eye might be the single best indication for steroid therapy for this disease. The discrete nature of these episodes, brought on by an identified intrinsic or extrinsic source, allows for an appropriate use of a drug that we all know to not use indiscriminately. Of course, if the exacerbated dry eye is due to a medication change, alternatives should be discussed with the patient and decided upon in collaboration with the patient and his primary-care physician.
Corticosteroids and Dry Eye Corticosteroids mediate their anti-inflammatory effects primarily through modulation of the cytosolic glucocorticoid receptor at the genomic level. Different from conventional synthetic corticosteroids, loteprednol etabonate 0. In patients, loteprednol was found to provide a more rapid relief of dry-eye signs and symptoms, with greater efficacy than cyclosporine or artificial tears alone.
Corneal and conjunctival staining and tear-film breakup time were significantly improved from baseline, tear osmolarity decreased, and IL-1, IL-8 and monocyte chemo-attractant protein-1 were all significantly decreased at eight weeks compared to baseline. Thus, short-term steroid treatment was shown to improve all signs of dry eye in tandem with a lowering of tear cytokine levels.
Half of the patients were treated with preservative-free sodium hyaluronate and 0. The other 50 patients were treated with identical preserved therapies.
Researchers found that non-preserved therapies were more effective than their preserved counterparts in improving the following: While this study did not have a no-steroid arm, it was clear that all signs, symptoms and markers improved with treatment compared to baseline. While tear substitutes did not improve any sign of dry eye, fluorometholone, nepafenac and doxycycline all significantly improved corneal staining within two weeks.
Topical ketorolac, diclofenac and bromfenac were less effective and slower to show any effect. Aqueous tear production started to return to baseline within two weeks, although not significantly; however, all other groups still had reduced tear production even as far out as four weeks. This mitogen induces lymphocytic infiltration, necrosis and fibroplasia of lacrimal glands.
Clinical manifestations of reduced TFBUT, tear clearance and corneal staining were all inhibited by topical pre-treatment with dexamethasone 0. Post-exposure therapeutic efficacy was also shown when dexamethasone was administered two days following injection of ConA. Dexamethasone in particular is known to modify a wide variety of immune functions by promoting a tolerogenic immune response.
Exploring different formulations of corticosteroids, or different platforms for their delivery, might be the ideal choice for treating acute episodes of dry-eye disease without worrying about steroid abuse or toxic effects with chronic use. One exciting new prospect in ophthalmic steroid development is the resorbable polyethylene glycol-based hydrogel punctal plug depot delivery system Ocular Therapeutix. Inserted non-invasively through the inferior punctum, the plug resides within the canaliculus, delivering a four-week release of the corticosteroid to the ocular surface.
This delivery system for dexamethasone contains approximately 0. Over time, and through hydrolysis, the depot-drug softens, liquefies and is cleared through the nasolacrimal duct.
This drug-eluting plug is already entering Phase III clinical trials for postoperative inflammation, and has shown significant clinical efficacy compared with placebo, with percent retention through day 14, and 97 percent through day In this study, no long-term spikes in IOP were encountered, and the placebo subjects were prescribed significantly more rescue medication ocutx.
This concept might be ideal for a dry-eye drug treating a spike of acute inflammation for several reasons: A constant, slow release of the active drug ensures effective concentrations; the choice of a local steroid allows for anti-inflammatory and anti-immune effects, altering the course of future localized autoimmune responses to noxious stimuli; and the unique pharmacokinetics improve the safety profile of the corticosteroid.
Choosing a steroid like dexamethasone during these acute overlays of dry eye might benefit the patient not only in the short term by quenching the inflammatory reaction, but also might dampen responses to future environmental exposures, promoting a non-pathological response to adverse stimuli. We look forward to more studies into this fascinating area of dry-eye research and hope to be able to use key pieces of this new information to better the treatment and lives of our patients.
