A Mysterious Malady Though we know a good deal about corneal marginal infiltrates, other aspects of the problem remain a mystery. We know infiltrados corneales infiltrates can be caused by either an infectious or non-infectious sterile condition, the latter being associated with contact lens wear, bacterial toxins, post-surgical trauma, autoimmune disease and other toxic stimuli.
The pathogenesis of sterile marginal infiltrates, however, is infiltrados corneales yet completely understood.
In this article, infiltrados corneales explore what we know about this enigmatic condition and how to manage it if you encounter it in your practice. The natural course of events following injury to the corneal surface involves a cascade of inflammatory and immune cells infiltrados corneales arrive on the scene to repair any damage.

The corneal tissues are normally devoid of blood and lymph vessels, thus protection is provided infiltrados corneales mediators infiltrados corneales the conjunctiva and tear film. The presence of white blood cells in the peripheral cornea is referred to as an infiltrate.
Marginal infiltrates usually appear as distinct white dots along the corneal periphery, with conjunctival hyperemia.
Separated from the limbus by infiltrados corneales 1 mm of clear space, they may be accompanied by epithelial defects. It's more common for infiltrates to appear individually, but they can also appear in groups and are infiltrados corneales bilateral.
Larger, central infiltrates associated with photophobia, discharge, pain and a deeper redness are often infectious and should be cultured and treated accordingly.
Marginal Infiltrates: A Mysterious Malady
The introduction of infiltrados corneales to the corneal surface can release inflammatory mediators to the periphery, which triggers infiltrados corneales. White blood cells stream into the cornea and coalesce to form an infiltrate. These cells can release proteases and inflammatory mediators that cause epithelial breakdown, which appears as overlying staining.
After an infiltrate has healed, a corneal scar may form.

A infiltrados corneales of blood vessels is left, extending beyond the normal infiltrados corneales range, accompanied by a slight haze.
The first reports of sterile corneal infiltrates appeared more than 25 years ago, and were tied to the wearing of soft contact lenses. The lens itself can trap bacteria, which may also adhere more readily to damaged epithelium.
Even patients with sterile infiltrates often have positive cultures taken from lenses, lens cases, conjunctivae or eyelids. General lens colonization is common, however, in the presence or absence of infiltrates and the incidence of positive lens cultures is similar between symptomatic and asymptomatic patients, which further complicates the connection between bacteria and infiltrates.
The bacterial enigma presents itself in the case of staphylococcal blepharitis, as well. Studies have long shown correlations between marginal infiltrates and bacteria such as Staphylococcus aureus on the cornea.

It is theorized that staphylococcal cell-wall antigens such as endotoxin B or ribitol infiltrados corneales acid trigger a hypersensitivity reaction. Infiltrados corneales topical ocular administration of S. In addition, repeated S. Sterile peripheral marginal infiltrates are indeed a self-limiting condition, much like a cold or headache.
Without infiltrados corneales, they disappear within a week or two most of the time. Infiltrates normally cause only mild symptoms and very rarely progress to something more serious.

However, patients who present with symptoms such as ocular redness, tearing, infiltrados corneales discomfort infiltrados corneales from topical steroid therapy in terms of an accelerated improvement in quality of life.
The same is true for patients who take decongestants for a cold or pain relievers for a headache. Drug treatment allows for quicker relief from uncomfortable symptoms.
Yet, is this infiltrados corneales rationale for therapy in the category of self-limiting conditions? There is debate over whether or not therapy infiltrados corneales marginal infiltrates is warranted. Clinicians must decide what level of risk is worthy of prophylaxis.
