Haemophilus Influenzae-Associated Scleritis after Pterygium Excision

Abstract

Purpose: To report a case of Haemophilus influenzae-associated scleritis after pterygium excision. Methods: Case report. Results: A 63-year-old male with no underlying autoimmune disorders developed scleritis 7 years after pterygium excision. Initially, topical medical treatment was given. Due to the persistent ocular pain and uncontrolled inflammation for 4 months, surgical debridement was performed. A culture taken intraoperatively grew Haemophilus influenzae; systemic and topical antibiotics in response to the culture result were subsequently prescribed. The scleral inflammation completely resolved, and visual acuity had returned to 20/20 three months after debridement. Conclusions: Haemophilus influenzae is a relatively rare pathogen in infectious scleritis after pterygium excision. An accurate diagnosis and proper treatment including surgical intervention will not only resolve inflammation but also preserve good visual acuity.
