Orbital abscess: 20 years' experience at a tertiary eye care center.

Purpose: To study the clinical, microbiological profile and management outcomes of orbital abscess at a tertiary care center in South India.

Material And Method: In a retrospective interventional case series, we reviewed all patients diagnosed with orbital cellulitis from 2000-2020. The data analyzed included demographic profile, clinical and radiological features, microbiological profile, and management outcome.

Results: A total of 921 cases of orbital and periorbital infections were reviewed. Seventy-two cases were diagnosed as orbital cellulitis. Thirty-four cases (47.22%) had radiological evidence of orbital abscess. The median age was 20.63 years. Three patients (8.82%) were neonates. A male preponderance was noted (23, 67.65%). Sinusitis (10, 29.41%) and diabetes (5, 14.7%), were the most common predisposing factors. Optic neuropathy was seen in 15 (44.11%) patients, cavernous sinus thrombosis in two patients (5.88%), and septicemia in one patient (2.94%) Multiple orbital abscesses were noted in 7 (20.59%) cases. All patients underwent surgical drainage. was the most common organism isolated in 14 patients (41.18%). Vision improvement or stabilization was seen in all except 3 (8.82%).

Conclusion: Orbital abscess is a potential sight-threatening orbital infection. The infective process can spread and ascend up to involve cavernous sinus thereby becoming life-threatening. A timely diagnosis and intervention can halt the disease process and help restore vision in many cases.
