Differences in the design of the diffractive IOLs translate into differences in optical quality at their foci, through-focus performance, and halo features, which can offer further information to surgeons when selecting which IOL to implant.
Purpose: To report the first case of acute endophthalmitis caused by Alloiococcus otitidis after a dexamethasone intravitreal implant. Methods: A 74-year-old female was treated with intravitreal Ozurdex® in her left eye for central retinal vein occlusion (CRVO). Best-corrected visual acuity (BCVA) in the eye was 4/20. Intravitreal injection was uneventful. At 48 h after injection, she developed ocular pain and visual acuity had dropped to light perception. Endophthalmitis associated with intravitreal injection was suspected. Results: The patient did not show a favorable clinical response following systemic, intravitreal, and topical fortified antibiotics. We then performed a vitreous biopsy and removed the Ozurdex implant by pars plana vitrectomy. A vitreous culture was positive for A. otitidis. At the 2-month follow up, no inflammation was observed, but due to CRVO and probably aggravated by endophthalmitis, the fundus showed macular fibrosis. The final BCVA was finger counting at 30 cm in her left eye. Conclusions: In cases of an intravitreal implant associated withendophthalmitis, we recommend removal of the device because it may act as a permanent reservoir of organisms if it remains in the vitreous cavity.
The present results, which reflect IOL characteristics in optics, profile, and add power, may contribute to help surgeons decide on the type of IOL most suitable for each patient, especially those with high visual demands at near and intermediate distances.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
