Purpose: To investigate the UBM characteristics of presumed trematode-induced granulomatous uveitis.
Design: Prospective case series.
Methods: Thirty patients who presented with anterior chamber (AC) granuloma were included. UBM Imaging included Cornea, iris, AC angle, posterior chamber, ciliary body, and vitreous base.
Results: Thirty eyes were included with a mean age of 12.4 ± 2.5 years. UBM findings were retrocrneal membrane (33%), sub conjunctival nodule (10%), AC granuloma (100%); peripheral anterior synechia, granuloma-like lesion in posterior chamber; ciliary body edema with localized granuloma at specific site (100%), cataract in 30% either localized or generalized, and dot or thread-like high reflection on vitreous base in (20%).
Conclusion: Presumed trematode-induced AC granuloma is common among children living in the rural areas of Egypt. UBM examinations can demonstrate various pathologic changes of anterior segment of the eye and provide objective evidence for the exact origin of those granulomas.

Parasite-induced modification of host behavior increasing transmission to a next host is a common phenomenon. However, field-based studies are rare, and the role of environmental factors in eliciting host behavioral modification is often not considered. We examined the effects of temperature, relative humidity (RH), time of day, date, and an irradiation proxy on behavioral modification of the ant (Förster, 1850) by the brain-encysting lancet liver fluke (Rudolphi, 1819).

Purpose: To describe the surgical management of presumed trematode-induced granulomatous intermediate uveitis (PTIGIU) not responding to medical treatment in controlling the inflammation.
Methods: A prospective, interventional, single-center study in which patients with a history of fresh canal water contact and PTIGIU were enrolled. All patients underwent lensectomy-pars plana vitrectomy (PPV) and post-operative control of inflammation, functional and anatomical outcomes were assessed.
