Fungal orbital cellulitis is usually seen in immunocompromised individuals, and opportunistic pathogens are the main etiology. We herein report a case of fungal orbital cellulitis due to Aspergillus in a patient with no history of trauma. A 48-year-old man presented to the emergency room of our hospital with a 2-week history of periorbital swelling, conjunctival hyperemia, and chemosis of his right eye. The visual acuity of his right eye was 6/20, and the intraocular pressure was 44 mmHg. The main clinical findings were proptosis of the right ocular globe with conjunctival hyperemia and a palpable infratemporal orbital mass. Laboratory testing failed to detect the presence of a pathogenic infection, and the lesions on computed tomography images resembled those of a malignant tumor of the orbit. The diagnosis was finally confirmed by postoperative pathological examination, and the patient responded favorably to debridement combined with antifungal therapy. Histopathological examination may help to reveal the nature of this disease. Surgical removal of inflammatory lesions can serve as an important diagnostic and treatment method for fungal orbital cellulitis., Competing Interests: Declaration of conflicting interestsThe authors declare no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

A 64-year-old man with a known history of diabetes and hypertension presented to the Accident and Emergency Department with a 2-day history of sudden decreased vision in the right eye. Temporal arteritis was suspected with an elevated erythrocyte sedimentation rate (71 mm/h), and oral prednisolone was started immediately. Four days later, the patient's right eye vision deteriorated from 0.6 to 0.05, with a grade-4 relative afferent pupillary defect and ophthalmoplegia. Computed tomography showed a contrast-enhancing orbital apex mass in the right orbit abutting the medial and lateral portions of the optic nerve with extension to the posterior ethmoid and sphenoid sinuses. A transethmoidal biopsy was performed which yielded septate hyphae suggestive of Aspergillus infection. Ten days later, the patient's right eye vision further deteriorated to hand movement with total ophthalmoplegia. MRI of the orbit showed suspicion of cavernous sinus thrombosis. A combined lateral orbitotomy and transethmoidal orbital apex drainage and decompression were performed to eradicate the orbital apex abscess. Drained pus cultured Aspergillus. The patient was prescribed systemic voriconazole for a total of 22 weeks. The latest MRI scan, performed 8 months after surgery, showed residual inflammatory changes with no signs of recurrence of the disease. To our knowledge, this is the first case report which describes the use of a combined open and endoscopic approach for orbital decompression and drainage in a case of orbital aspergillosis. We believe the combined approach gives good exposure to the orbital apex, and allows the abscess in this region to be adequately drained.

Background/Aim: To describe a case of invasive orbital aspergillosis and evaluate treatments and outcomes. Methods: A case report and review of orbital aspergillosis treatment with voriconazole in the English language literature. Conclusion: Amphotericin B with debridement is the current standard of care for orbital aspergillosis; however, its prognosis is unfavorable. When compared to amphotericin B, voriconazole demonstrates a survival benefit, has less systemic toxicity, and is better tolerated by patients. While a prospective trial comparing amphotericin B to voriconazole in orbital aspergillosis is not feasible, there is evidence to support the use of voriconazole as primary therapy.

The article describes two cases of feline orbital aspergillosis caused by Aspergillus udagawae and Aspergillus viridinutans. An overview of other reported feline cases of orbital aspergillosis is presented. It discusses the materials and methods used in both cases, the comparative sequence analysis and molecular analysis results obtained in the case study, and other findings obtained after diagnosing the subjects using histopathologic examination and mycological identification.
