A schwannoma is an uncommon benign orbital tumor that arises from Schwann cells in the peripheral nervous system. Schwannoma with cystic degeneration is an even more rarely reported entity. Clinical examination alone is inadequate for the diagnosis. Radiological examination, like computed tomography (CT) scans, can help in the diagnosis; however, the diagnosis can only be confirmed by histopathological examination (HPE) after excision biopsy. Here, the authors report four cases of orbital schwannoma with cystic degeneration that presented with proptosis and decreased vision. CT scans showed a well-defined non-enhancing intraconal mass with cystic spaces. The histopathological examination was diagnostic for orbital schwannoma with cystic degeneration. Schwannoma should be included in the differential diagnosis of cystic orbital lesions.

Oculoplastic surgeries encompass both emergency surgeries for traumatic conditions and infectious disorders as well as elective aesthetic procedures. The COVID-19 pandemic has brought about a drastic change in this practice. Given the highly infectious nature of the disease as well as the global scarcity of medical resources; it is only prudent to treat only emergent conditions during the pandemic as we incorporate evidence-based screening and protective measures into our practices. This manuscript is a compilation of evidence-based guidelines for surgical procedures that oculoplastic surgeons can employ during the COVID-19 pandemic. These guidelines also serve as the basic framework upon which further recommendations may be based on in the future, as elective surgeries start being performed on a regular basis.
