Streptococcus mitis/oralis endophthalmitis management without phakic intraocular lens removal in patient with iris-fixated phakic intraocular lens implantation

Abstract

Background: To report a case of Streptococcus mitis/oralis endophthalmitis management which had developed after complicated iris-fixated phakic intraocular (pIOL) lens implantation. Case presentation: A 23-year-old-woman received pIOL implantation followed secondary intraocular intervention to lower intraocular pressure. The patient presented with severe pain and decreased visual acuity and was managed with intravitreal and intracameral antibiotic injection with topical applications of fortified antibiotics. Culture of aqueous humor was positive for S. mitis/oralis, which was sensitive to the empiric antibiotic regimen. Clinical features started to improve 5 days after treatment and the pIOL was left in place. The uncorrected distant visual acuity and endothelial cell count were 20/32 and 3143cells/mm(2) four weeks after treatment, respectively. Conclusion: S. mitis/oralis endophthalmitis after pIOL implantation could be managed with appropriate antibiotic administration without pIOL removal if accompanied by rapid clinical improvement after the initial intensive management in the absence of vitreous involvement.
