Coronavirus disease 2019 (COVID-19) infections may be associated with a wide range of bacterial and fungal co-infections. We report the case of a patient with COVID-19 infection, which, during the course of the treatment, developed rhino-orbital mucormycosis. A 60- year-old male patient, a longstanding diabetic, with a positive reverse-transcriptase polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was admitted for treatment. He received parenteral meropenem and oral oseltamivir with parenteral methylprednisolone. Over the course of the admission, he developed signs of orbital cellulitis. Magnetic resonance imaging (MRI) of the brain, orbits, and paranasal sinuses, revealed soft tissue swelling in the right preseptal, malar, premaxillary and retrobulbar regions with paranasal sinusitis. A nasal biopsy revealed broad aseptate filamentous fungal hyphae suggestive of mucormycosis, which was confirmed on culture. Extensive use of steroids/monoclonal antibodies/broad-spectrum antibiotics may lead to the development/exacerbation of a preexisting fungal disease. Physicians should be aware of the possibility of secondary invasive fungal infections in patients with COVID-19 infection.

Purpose: To standardize a nomenclature system for defining clinical phenotypes, and outcome measures for reporting clinical and research data in patients with ocular tuberculosis (OTB). Methods: Uveitis experts initially administered and further deliberated the survey in an open meeting to determine and propose the preferred nomenclature for terms related to the OTB, terms describing the clinical phenotypes and treatment and reporting outcomes. Results: The group of experts reached a consensus on terming uveitis attributable to tuberculosis (TB) as tubercular uveitis. The working group introduced a SUN-compatible nomenclature that also defines disease "remission" and "cure", both of which are relevant for reporting treatment outcomes. Conclusion: A consensus nomenclature system has been adopted by a large group of international uveitis experts for OTB. The working group recommends use of standardized nomenclature to prevent ambiguity in communication and to achieve the goal of spreading awareness of this blinding uveitis entity.

Diagnosis and management of ocular tuberculosis (OTB) poses a significant challenge. Mixed ocular tissue involvement and lack of agreement on best practice diagnostic tests together with the global variations in therapeutic management contributed to the existing uncertainties regarding the outcome of the disease. The current review aims to update recent progress on OTB. In particular, the Collaborative Ocular Tuberculosis Study (COTS) group recently standardized a nomenclature system for defining clinical phenotypes, and also proposed consensus guidelines and an algorithmic approach for management of different clinical phenotypes of OTB. Recent developments in experimental research and innovations in molecular diagnostics and imaging technology have provided a new understanding in the pathogenesis and natural history of the disease.

Ocular involvement in acute disseminated tuberculosis is often seen, with the most common manifestation being choroidal tubercles. Early detection of these lesions may be important in treatment.

Hantavirus infections are an emerging infectious disease that is beginning to be recognized both worldwide and in India as a cause of hemorrhagic fever that may present as a pulmonary syndrome or as a renal syndrome. Reports of ocular involvement are rare and include transient myopia, low intraocular pressure, conjunctival hemorrhages and changes of intraocular dimensions. Eleven patients (10 males, one female, mean age 37.6 years) were admitted to the intensive care unit for pyrexia of unknown origin or hemorrhagic fever following exposure to flood waters. Five male patients (mean age 31.6 years) were identified as suffering from hantavirus infection. In one patient, dot and blot intraretinal hemorrhages were seen in the macula of one eye and streak hemorrhages of the disc in the other. In the remaining four, no fundus abnormalities were seen. Ophthalmologists should be aware of these features.

Ocular tuberculosis was a common finding in this study and was found in profoundly immunocompromised patients with disseminated tuberculosis. Diagnosis of ocular tuberculosis may help reduce HIV/tuberculosis co-infection mortality.
