Ophthalmomyiasis externa caused by Oestrus ovis.

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.

Treatment of refractory diabetic macular edema with a fluocinolone acetonide implant in vitrectomized and non-vitrectomized eyes.

AIM: To report real-life data on the use of an intravitreal fluocinolone acetonide implant in the treatment of refractory diabetic macular edema (DME) in pars plana vitrectomized (PPV) and non-PPV eyes. METHODS: This was a comparative retrospective observational study of 23 eyes with chronic DME. Best-corrected visual acuity (BCVA) and central macular thickness (CMT) were recorded at baseline, 1, 4 and 12mo. Descriptive statistics and non-parametric tests were performed to analyze and compare PPV and non-PPV eyes. RESULTS: Seven PPV and 16 non-PPV eyes were included in the study. Median BCVA in the non-PPV group varied from 0.65 logMAR [Interquartile range (IQR): 0.40] at baseline to 0.42 logMAR (IQR: 0.40) at 12mo. Median CMT varied from 430 µm (IQR: 131.3) at baseline to 317 µm (IQR: 107.5) at 12mo. Median BCVA in the PPV group varied from 0.60 logMAR (IQR: 0.62) at baseline to 0.74 logMAR (IQR: 0.34) at 12mo. Median CMT varied from 483 µm (IQR: 146) at baseline to 397 µm (IQR: 132) at 12mo. Of 0/7 eyes and 1/16 eyes in the PPV and non-PPV eyes respectively had a baseline visual acuity of 6/12 or better (0.3 logMAR). At last follow up, 1/7 and 5/16 eyes in the PPV and non-PPV group respectively achieved a visual acuity of 6/12 or better. CONCLUSION: Visual outcomes are modest following the use of the fluocinolone acetonide implant for chronic DME. The steroid implant is a useful treatment option in the management of refractory DME in vitrectomized and non-vitrectmized eyes.
