Ophthalmic manifestations of paranasal sinus disease: a clinical grading system.

BACKGROUND: Ophthalmic complications are common manifestations of paranasal sinus disease. We propose a clinical grading system to standardize the category, treatment, and outcome of these complications.
METHODS: Forty-two patients with paranasal sinus disease-induced ophthalmic complications were included in the study. The patients were categorized according to their clinical presentation: Grade I, patients with anatomical disturbance; Grade II, patients with ophthalmic functional involvement; Grade III, patients with orbital infection; and Grade IV, patients with visual impairment.
RESULTS: The age of the patients ranged from 8 to 65 years (mean = 30 years). Overall, 36% patients had ophthalmologic manifestations with anatomical disturbance (Grade I), 26% had functional disturbance (Grade II), 26% had orbital infections (Grade III), and 12% had visual loss (Grade IV). The cause of the ophthalmic manifestations was allergic fungal sinusitis in 50%, chronic rhinosinusitis in 36%, acute sinusitis in 10%, and mucocele in 4%. The most common ophthalmic manifestation was proptosis (36%), followed by orbital infection (26%), functional involvement (26%), and visual impairment (12%). The patients underwent functional endoscopic sinus surgery and medical treatment when indicated. The outcome in Grades I, II, and III was favorable; the outcome in Grade IV was not favorable.
CONCLUSION: This simple clinical grading system provides a useful tool for assessing the overall status of ophthalmic complications of Acute and chronic paranasal sinus disease at the initial clinical assessment and for subsequent management of these complications.
