This report describes the case of a woman in her early 20s who presented with a 3-day history of mobile foreign bodies and watering from her right eye. She had recently returned from vacation on a Greek island and presented to an ophthalmology unit in London, UK. A sample taken demonstrated Oestrus ovis infestation and confirmed the diagnosis of ophthalmomyiasis externa. She was treated with prophylactic topical antibiotics and subsequently made a full recovery. This was only the sixth presentation of O. ovis ophthalmomyiasis externa documented within the UK and the only case documented within the last 20 years. This is the fifth documented case found to have been transmitted within Greece.
PurposeTo assess the effectiveness of the Fluocinolone intravitreal implant (Iluvien) in patients with diabetic macular oedema (DMO) following previous pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR). The data from vitrectomised eyes are compared with a consecutive group of non‐vitrectomised eyes with DMO who received the Iluvien implant in our institution.MethodsRetrospective analysis of a consecutive series of patients who received the Iluvien implant for DMO. Best‐corrected visual acuity (BCVA) and central retinal thickness (CRT) were evaluated at baseline and 0–2 months, 3–5 months and 6–12 months following placement of the implant. Analysis of variance was carried out using Stata 14.1 (StatCorp LP) Software.ResultsSeven eyes with recent PPV and 17 eyes without previous PPV received an Iluvien implant for DMO. Mean improvement in BCVA in the PPV group to 6–12 months was 0.33 logMAR (95% CI: −0.2 to 0.8) compared with 0.13 logMAR (95% CI: 0.0–0.2) in the no PPV group (p = 0.355). Mean improvement in CMT in the PPV group to 6–12 months was 59.6 μm (95% CI: 18.0–137.2) compared with 78.4 μm (95% CI: 21.3–126.9) in the no PPV group (p = 0.745). Individual OCT images showed persistent cystoid macular oedema in 7/7 eyes in the PPV group. A persistent pre retinal hyper‐reflective line at the macula suggestive of residual cortical vitreous or pre retinal membrane was identified in 4/7 eyes in the PPV group and 9/17 eyes in the non‐PPV group.ConclusionsVitreoretinal interface proliferation may explain the absence of a response to intravitreal Iluvien in some DMO eyes. Prospective randomised studies are needed in order to establish a uniform evidence based approach for classification and treatment in vitrectomised eyes.
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.
