Persistent placoid maculopathy

What it is

Persistent placoid maculopathy is characterised by white plaque-like lesions involving the macula but sparing the peripapillary areas of both eyes. It has been described in five patients. In contrast to patients with macular serpiginous choroiditis presenting with similar lesions, the five patients reported so far with persistent placoid maculopathy had good visual acuity until the onset of choroidal neovascularization (CNV) or pigmentary mottling. The macular lesions fade after several months or years, but the vascular anomalies persist leading to a loss of central vision.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Related health topics

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
