PIgment epithelial diseases with abnormal choroidal perfusion
American Journal of Ophthalmology
|November 1, 1980
Summary
This study identified three groups of patients with retinal pigment epithelium swelling and choroidal filling abnormalities, suggesting a common cause of choroidal hypoperfusion and pigment epithelial infarct. No systemic causes were found.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Choroidal Abnormalities
Background:
- Early-stage disease presentation in sixteen patients.
- Focus on retinal pigment epithelium (RPE) swelling and choroidal filling.
- Investigating potential underlying causes of these ocular findings.
Observation:
- Patients categorized into three groups based on RPE lesion presentation.
- Group 1: Multifocal RPE lesions, similar to acute posterior multifocal placoid pigment epitheliopathy (APMPPE).
- Group 2: Confluent RPE lesions without retinal detachment.
- Group 3: Multifocal RPE lesions with associated retinal detachment.
Findings:
- All patients exhibited RPE swelling and widespread choroidal filling abnormalities.
- Postulated diffuse choroidal hypoperfusion and focal RPE infarct as the underlying pathology.
- No significant systemic abnormalities identified in any patient group.
Implications:
- Suggests a unifying mechanism of choroidal hypoperfusion and RPE damage in these conditions.
- Highlights the spectrum of presentation from APMPPE-like lesions to retinal detachment.
- Further research needed to identify the diverse basic disorders causing these findings.
