Not all orbital inflammations in the COVID-19 era are due to mucormycosis – A case of orbital pseudotumour leading to vision loss

A 57-year-old male patient with type 2 diabetes mellitus who had survived severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) disease (COVID-19) presented with loss of vision in the right eye (RE) of 20-day duration. The patient had been diagnosed elsewhere with orbital mucormycosis and had been treated for it. The patient developed vision loss in RE 1 week after the initiation of treatment. At the time of presentation in our institute, vision in RE had reduced to no perception of light. Examination showed a relative afferent pupillary defect and pale optic disc in RE. Gadolinium-enhanced contrast magnetic resonance imaging of the brain, orbit and paranasal sinuses suggested perineuritic type of idiopathic orbital inflammation. In the present COVID-19 scenario, diagnosis other than mucormycosis should be kept in mind when dealing with cases of orbital inflammation

Unilateral branch retinal vein occlusion with vitreous hemorrhage mimicking Terson's syndrome

We report a case of unilateral traumatic vitreous hemorrhage following injury to the anterior cranium. A 55-year-old female presented with gradual loss of vision in her left eye following trauma to the anterior cranium. Funduscopy revealed fresh vitreous hemorrhage. Conservative management was futile with further visual deterioration over the next 2 weeks. During pars plana vitrectomy, fresh retinal hemorrhages were noted along the superotemporal (ST) vein suggesting bleed due to vein rupture. Postoperative fundus fluorescein angiography indicated ST branch retinal vein occlusion. Since trauma can be an inciting factor for both, this case could be a variant of Terson's syndrome
