To study the risk factors for development of COVID-19 associated rhino-orbital-cerebral mucormycosis (ROCM) during the COVID-19 pandemic in India. Multi-centric retrospective case-control study conducted from October 2020 to May 2021. Cases comprised of consecutive patients of COVID-19-associated ROCM (CA-ROCM) presenting at the participating ophthalmic institutes. Controls comprised of COVID-19-positive or COVID-19-recovered patients who did not develop ROCM. Comparative analysis of demographic, COVID-19 infection, treatment parameters and vaccination status between cases and controls performed. Clinical and imaging features of CA-ROCM analyzed. There were 179 cases and 361 controls. Mean age of presentation in cases was 52.06 years (p = .001) with male predominance (69.83%, p = .000011). Active COVID-19 infection at the time of presentation of ROCM (57.54%, p < .0001), moderate to severe COVID-19 (p < .0001), steroid administration (OR 3.63, p < .00001), uncontrolled diabetes (OR 32.83, p < .00001), random blood sugar >178 mg/dl were associated with development of CA-ROCM. Vaccination showed a protective effect (p = .0049). In cases with intracranial or cavernous sinus extension there was history of steroid administration (OR 2.89, p = .024) and orbital apex involvement on imaging (OR 6.202, p = .000037) compared to those with only rhino-orbital disease. Male gender, active COVID-19 infection, moderate or severe COVID-19, uncontrolled diabetes, steroid administration during COVID-19 treatment are risk factors for developing rhino-orbital-cerebral mucormycosis. Vaccination is protective. Random blood sugar of >178 mg/dl in COVID-19 positive or recovered patients should warrant close observation and early detection of ROCM. Presence of ophthalmoplegia, blepharoptosis at first clinical presentation and orbital apex involvement on imaging are associated with intracranial extension in ROCM.

Primary conjunctival amyloidosis is a rare entity. We present a patient with bilateral conjunctival amyloid, presenting with ptosis, ectropion, and chalazion-like lumps. Histopathology showed an amorphous eosinophilic lesion, and staining with Congo red showed apple-green birefringence.

Purpose: To describe visual morbidity in thyroid orbitopathy in Asian Indians and the factors influencing its onset. Methods: A retrospective chart review was performed for patients with thyroid related orbitopathy seen between May 2014 and April 2019. Three hundred and one patients were included in the study. Relevant history, clinical findings, investigations, and treatment were documented. Results: Nineteen percent of patients had at least 1 visual morbidity feature such as compressive optic neuropathy, exposure keratopathy or diplopia, requiring intravenous glucocorticoid. Male gender, older age, and diabetes were the significant risk factors for high visual morbidity (all P < 0.05). Systemic thyroid status, degree of proptosis, and duration of disease were not significant. Average dose of intravenous glucocorticoid needed was 3.8 g; 24 (7.9%) patients required orbital decompression, and 13 (4.3%) needed eyelid surgery. At the last follow-up, 97% of patients had vision 6/12 or better in both eyes. Conclusion: There is significant visual morbidity found in Indian patients with TED, even with moderate proptosis and systemic control of thyroid status. This is the first set of data on the subject.
