Angiostrongyliasis is the most common cause of eosinophilic meningitis worldwide and is primarily characterized by eosinophilic meningitis, meningoencephalitis, or myelitis. It is caused by ingestion of the nematode Angiostrongylus cantonensis, the rat lungworm (or apple snail). The most common route of infection is by ingestion of parts of the intermediate hosts like mollusks or food contaminated with infective third stage larvae. Following ingestion, the larvae migrate through the intestinal walls into the bloodstream and further into the central nervous system where they cause meningo-encephalo-myelitis and can have a variety of ocular manifestations. We present a case of a Caucasian United States Marine who suffered severe meningo-encephalo-myelitis with papilledema following ingestion of a raw Giant African Snail (Lissachatina lutica) while stationed in Japan. He developed eosinophilic meningoencephalitis, polyneuropathy, motor weakness, and papilledema. We describe the unique clinical features of this disease in our patient.

Minimally invasive glaucoma surgery (MIGS) provides a safe option for individuals with mild to moderate open-angle glaucoma to reduce their need for pharmacologic therapy or more extensive ab externo surgeries. In this report, we describe a surgical technique using both the Kahook Dual Blade and Gonioscopy-assisted transluminal trabeculotomy (GATT), to treat a 23-year-old active duty female with idiopathic uveitis and subsequent corticosteroid-induced glaucoma who presented with consistently elevated intraocular pressure (IOP) measurements despite maximal pharmacologic interventions. This combination was effective in consistently lowering intraocular pressure for at least 12 months in a young, phakic, active duty patient with uveitis and steroid-responsive open-angle glaucoma.
