Abstract Details

Purpose:

Pt.62 years old man on the right red eye lasting 3 days and a loss of vision and pus excretion lasting one day.

Setting:

Educational Hospital of Rakican, Murska Sobota, Slovenia

Methods:

In the case of corneal ulcers caused by Moraxella sp, even though the organism is described as being clinically indolent it can also be extremely destructive to corneal tissue. The keratitis it produces usually deepens rather than spreading peripherally, and the associated inflammatory response can be so hyperacute that a hyphema forms within a hypopyon—a clinical feature that is usually seen in ulcers infected with much more virulent bacteria. Moraxella is also paradoxically sensitive to most antibiotics, and resistant strains rarely develop. Even in its response to treatment it can be said that a Moraxella corneal ulcer often appears to be down but it is never out.

Results:

Yet the clinical course of a Moraxella corneal ulcer can be uncommonly protracted and fraught with many complications. Even though the ulcer is almost always rapidly sterilised in the first few days of treatment, the destruction of the corneal tissue continues unabated, sometimes for weeks, requiring the addition of topical corticosteroids and other adjunctive therapeutic agents to prevent severe corneal necrosis and perforation.

Conclusions:

Once the diagnosis is confirmed with positive corneal scrapings and cultures, the truly difficult part begins: the battle to limit the necrosis of the corneal tissue that ultimately leads to scarring and visual disability.
