    Abstract:
    PURPOSE: We sought to describe the clinical features, responsible pathogens, management, and prognosis of infectious scleritis after pterygium excision. METHODS: A retrospective study through review of medical records of patients diagnosed with infectious scleritis after pterygium excision over a 10-year period at our institution. RESULTS: A total of 16 cases of infectious scleritis after pterygium excision was identified. Among them, eight were associated with sclerokeratitis, and six had multifocal scleral nodules with subconjunctival abscesses. Culture results were positive in 15 (93.8%) cases. Pseudomonas was isolated in 13 (81.3%) patients, fungus in three (18.8%), and two had a mixed growth (12.5%). Based on the in vitro susceptibility test, four (31%) Pseudomonas isolates were resistant to gentamicin, whereas all isolates were sensitive to amikacin. During the course of treatment, eight cases were complicated by vitreous opacity, four developed glaucoma, four had serous retinal or choroidal detachment, and two had secondary cataract. Scleral infection recurred in two patients after cessation of therapy. Among the nine patients treated with medical therapy, two eyes were enucleated, whereas only two attained a visual acuity of > or =2/200 at the end of the follow-up period. On the other hand, seven patients had combined antibiotic therapy and surgical debridement. The number of surgical debridement ranged from one to three, with an average of 1.4. In this combined-treatment group, only one patient required enucleation, and five cases attained a visual acuity of > or =2/200. The duration of hospitalization for patients with combined treatment was 21.2+/-4.8 days compared with the 28.4+/-5.0 days for those with medical treatment alone (p = 0.035). CONCLUSION: Surgical debridement in combination with appropriate antimicrobial therapy shortens the course of treatment and improves the visual outcome of severe infectious scleritis after pterygium excision.
