Diffuse Unilateral Subacute Neuroretinitis
Diffuse unilateral subacute neuroretinitis is a parasitic disease caused by any of several nematodes that travel to the subretinal space and live there for months to years producing photoreceptor destruction, scarring, and intraocular inflammation. Unilateral visual field loss is characteristic. Late cases are often misdiagnosed as unilateral retinitis pigmentosa.
