Study finds, Clinical Characteristics and Visual Outcomes in
A Study was conducted to describe the presentation, microbiology, management, and prognosis of eyes with endophthalmitis following Boston keratoprosthesis (KPro) implantation. Retrospective case series with history, diagnostics, management, and outcomes data in endophthalmitis following KPro implantation.

--Of 137 KPro-implanted eyes, 7 eyes of 7 patients developed endophthalmitis.

--On presentation, 6 reported decreased visual acuity (VA), and only 1 reported pain.

--Peripheral corneal ulcers were present in 2 eyes. Seidel testing was negative in all cases.

--6 eyes had retroprosthetic membranes. 1 underwent initial pars plana vitrectomy (PPV) with mechanical vitreous biopsy, whereas 6 received a needle vitreous tap—half of which were dry.

--Organisms were isolated following vitreous tap in 2 eyes: Streptococcus intermedius and Mycobacterium abscessus.

--Mean VA pre-endophthalmitis, at presentation, and at 6 months were 20/267, 20/5944, and 20/734, respectively.

--VA improved 9.08 ± 11.78 ETDRS lines from presentation to 6 months.

Conclusively, visual acuity at 6 months is linked to pre-endophthalmitis VA rather than presenting VA. Even if Seidel negative, endophthalmitis should be considered in the differential diagnosis of painless intraocular inflammation following KPro implantation.
