PURPOSE: To report the outcomes of a novel technique of scleral debridement in five consecutive cases of relentlessly progressive and fulminant infectious scleritis following corticosteroid exposure.
METHODS: Five consecutive patients of infectious scleritis with a common history of corticosteroids exposure, resulting from either an initial misdiagnosis of autoimmune scleritis or as anti-inflammatory adjunct to specific antimicrobial therapy. Data collection included presentation details such as photographs, clinical findings, microbiological analysis, treatment details and audit of surgical videos. Cases with undisputed diagnosis of infectious scleritis with microbiological evidence, without corticosteroid use, were excluded from the study.
RESULTS: After full-thickness scleral debridement and cessation of corticosteroids, favourable anatomical and visual outcome was observed in all cases; however, two patients required multiple scleral debridements due to progressive scleritis. Scleral patch graft was not used in any case. Microbiology detected infective organisms in two cases, while the remaining revealed negative results. Therefore, specific antimicrobial therapy was initiated in former, whereas empirical broad-spectrum regimen in patients with repeatedly negative microbiological results. No recurrence of scleritis or development of ciliary staphyloma was noted and anatomical integrity was maintained with normal intraocular pressure during follow-up.
CONCLUSION: This study highlights the fulminant and relentlessly progressive clinical course, that infectious scleritis can metamorphose into, despite specific antimicrobial therapy, if inadvertent corticosteroid therapy is administered. Full-thickness debridement without scleral patch graft, could achieve elimination of infectious foci, with favourable long-term anatomical and visual outcome. This technique could offer a potential last-resort approach in such cases where standard therapeutic modalities have not been successful.
