Dipetalonema reconditum in the human eye
Open accessAbstract
Editor,—Human ocular invasion by non-human filarial parasites has been reported for more than 200 years.1 2However, only just over a handful have actually been removed, described and identified in detail.3-6 Furthermore, the Dipetalonema species that have been described in three cases were thought to be from the body cavity of the natural hosts—the porcupine and the beaver.4 5 7 8 This report describes a case of Dipetalonema reconditum (usually associated with canine filariasis) in the human eye. It is noteworthy that this worm has morphological similarities to the canine heartworm Dirofilaria imitis , which in the past has been described in the human eye5 9 but not satisfactorily identified.10 ### CASE REPORT A 62 year old white resident of suburban Victoria, Australia, presented with a red and irritated right eye of 2 weeks' duration. This was exacerbated after a rural walking trip and did not improve with topical lubrication. He also noted mild diplopia on extreme right gaze. On examination, the visual acuity was 6/6 in the right eye and 6/4 in the left. There was mild limitation of right eye abduction. Localised bulbar conjunctival …

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
