A Proposed Diagnostic Algorithm for Fungal Orbital Infections after 20 Years of Experience in a Tertiary Eye Care Center– Egypt.

This study described the clinical presentations and proposed a diagnostic algorithm of fungal orbital infections based on 20 years of experience in a tertiary eye care center in Egypt. Medical Records of cases with orbital fungal infection from January 2000 to December 2019 were reviewed. The study included 45 patients. Mucormycosis was proven in 32 (71.1%) and aspergillosis in 13 (28.9%) patients. Thirty-five (77.8%) patients had predisposing factors mainly uncontrolled diabetes. Twenty-seven (60%) patients presented with orbital apex syndrome, 10 (22.2%) with orbital cellulitis and 8 (17.7%) with proptosis. The prognosis was generally poor (31.1% mortality, 8.88% exenteration and 11.1% self-evisceration). The proposed algorithm composed of six atypical clinical presentations mainly acute orbital apex and fulminating orbital cellulitis plus any radiological or microbiological findings. The proposed algorithm markedly reduced the complications after 5 years of the study. Once fungal orbital infection is suspected, treatment should start immediately. [ABSTRACT FROM AUTHOR]
