Chronic Post-operative Endophthalmitis caused by Acinetobacter Baumannii
Abstract
INTRODUCTION: Endophthalmitis caused by Acinetobacter baumannii (A. baumannii) has been rarely reported in literature.
CASE: A case of chronic post-operative endophthalmitis (CPE) from A. baumannii is reported here. A 50-year-old hypertensive male did not gain good vision following implantation of a three-piece +20.0 diopter intraocular lens (IOL) in his left eye (LE). Five months later, he was referred to retina services with gross diminution of vision and whiteness of the cornea. An ultrasound B scan was done to assess the posterior segment. The pars plana vitrectomy could not be done due to corneal opacity. The specimen obtained from the anterior segment wash was sent for culture and sensitivity.
OBSERVATION: The left eye (LE) had perception of light with an inaccurate projection of rays in all quadrants. On slit lamp examination, the cornea showed oedema, Descemet's membrane folds, peripheral vascularisation and a blood-stained endothelium. The intraocular pressure (IOP), keratometry and axial length were 12 mmHg, 41.5 x 45.75 and 22.25 mm respectively. The ultrasound B scan showed a well-defined vitreous opacity with moderate to high echoes in the posterior segment pointing towards vitritis with IOL and cortical lens matter drop. There was choroidal detachment (CD) in one quadrant. The anterior segment specimen grew colonies of A. baumannii sensitive to co-trimoxazole, minocycline, and levofloxacin. Oral levofloxacin 750 mg once a day for ten days was prescribed, but…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
