Controversies in the Management of Keratomycosis
Keratomycosis is a relatively rare but sight threatening disease. In view of the changing epidemiology of this severe problem the standard of care is continuously evolving and new treatment modalities - although often considered to be controversial - have to be explored. This symposium will discuss medical as well as surgical management options of fungal corneal infections, such as the use of mono- versus combination topical therapy, the need for corneal abrasion, the concomittant use of antiinflammatory medication, as well as corneal crosslinking, lamellar corneal transplantation and bioengineered tissue.

Mycotic keratitis is a very serious ophthalmological condition with a potentially sight-threatening course. There are a variety of proposed therapy regimens, but no scheme has yet enough evidence to be proven as a (gold-)standard. In this lecture, the current data for topical, systemic and immunosuppressive therapy, the controversies as well as own experiences from the University Hospital Düsseldorf will be presented. <strong>Roth M <sup>1</sup>, Geerling G <sup>1</sup></strong><span style="text-decoration: line-through;"><sup> 1</sup> Department of Ophthalmology, University Hospital, Düsseldorf, Germany

Farhad Hafezi (Zürich)

In many parts of the world, mixed (bacterial/fungal) and fungal keratitis represents a major diagnostic and therapeutic challenge to the ophthalmologist. PACK-Cross-Linking addresses both bacteria and fungi simultaneously, making the treatment more independent from the ophthalmologist’s clinical experience. The presentation will summarize the current state of knowledge in treating fungal infections using corneal cross-linking.

The author performed Big Bubble Deep Anterior Lamellar Keratoplasty (DALK) in patients with severe infectious keratitis and corneal blindness patients with corneal diseases not obviously involving the endothelial layer. No immunological rejection was observed after surgery. The visual acuity after big bubble DALK was satisfying and its therapeutic effects were comparable to that of conventional penetrating keratoplasty.

Nora Szentmáry (Homburg/Saar)

Since about a decade, with improvement of the surgical techniques, the number of anterior and posterior lamellar keratoplasties increases. Nevertheless, in our opinion, infectious keratitis is a contraindication of lamellar corneal transplantation, since with these techniques we can not completely eradicate the pathogens. This is especially true for mycotic keratitis, where several multiresistant microorganisms (e.g. Sarocladium, Fusarium) may result in repeat or persistent infection, with penetration of Descemet’s membrane. Therefore, timely, complete removal of the infected tissue is imprescendible for preservation of the eyeglobe and of vision.

Weiyun Shi (Qingdao)

Against the background of severe donor cornea shortage in China, the author creatively applied fresh porcine corneas in the treatment of infectious keratitis. With pulsed high-hydrostatic pressure, the xenogeneic cells and antigens of the cornea were removed thoroughly while the microstructure and the transparency were maintained. This kind of new bio-engineered cornea has improved eyesight for about a thousand patients, indicating a promising future in clinical application.
