[4] The commonly affected sites are the retinal pigment epithelium (RPE), outer retinal spaces, choriocapillaris, and, less commonly, the choroidal stroma. [14]. Characteristic findings of these diagnostic procedures include: Additionally, CNS imaging should be performed to rule out CNS vasculitis in all patients with a new diagnosis of APMPPE. The lesions gradually fade over the course of 1-2 weeks. Thus, the prevailing theory argues that a primary affectation of the choriocapillaris leads to secondary injury of the RPE and outer retina. Novak MA, Roth AS, Levine MR. Calcium oxalate retinopathy associated with methoxyflurane abuse. Slit-lamp exam reveals intraocular inflammation and anterior or vitreous cell. Optical coherence tomography, fundus autofluorescence and spectral domain optical coherence tomography angiography may also have a role in diagnosis [3][5][14].

[8] Lesions are scattered throughout the retina, in clusters, or in a linear fashion. Francis JH, Habib LA, Abramson DH, et al. Cases are often self-limited and visual symptoms resolve by 4 to 8 weeks. The multifocal ERG (mf-ERG) may be abnormal early when other tests such as visual field, full-field ERG (ff-ERG), and OCT are normal. Idiopathic multifocal choroiditis is a chronic and progressive bilateral inflammatory disease that may be associated with choroidal neovascularization and chorioretinal atrophy. The number of stimulation zones is comprised between 19 and 217.The number of stimulated zones must be a compromise since, as this number increases, the accuracy of fixation and the recording time increase.

[5] It is hypothesized that a preceding infection is responsible for stimulating the immune response that is observed in IMFC. Recurrent or chronic APMPPE may represent relentless placoid chorioretinitis, also known as ampiginous choroiditis, a disease that shares characteristics with APMPPE and serpiginous choroidopathy. [7] Other uses [ edit] Occasionally, punctate hemorrhaging can also be visualized. If you're over the age of fifty, it's especially important to have regular eye exams to protect your eye health.
