ABSTRACT Purpose To investigate the different clinical manifestations in Egyptian patients with orbital complications of rhinosinusitis (RS) according to the pathology within the paranasal sinuses. Methods The medical records of patients presented with chronic RS between August 2018 and December 2020 were retrospectively reviewed. Results This study included 64 patients: 28 patients with subperiosteal abscess (SPA), 10 with allergic fungal RS, 6 with isolated fungal RS, 6 with invasive fungal RS, and 14 with mucocele. The most common manifestation was proptosis, limitation of ocular motility, periorbital swelling, and pain. A relative afferent pupillary defect was present in all cases of invasive fungal sinusitis. Surgical interventions were performed in 63 out of 64 cases. All the ophthalmological manifestations were reversible except for patients with invasive fungal rhinosinusitis. Conclusion Orbital complications of RS may require early surgical intervention with multidisciplinary counseling between ophthalmologists, otorhinolaryngologists, radiologists, and neurologists.
