Degenerative choroidal sclerosis with a peculiar bilateral pattern.

T J Zimmerman, C R Fitzgerald

    Annals of Ophthalmology
    |April 1, 1975
    PubMed
    Summary

    This study identifies symmetrical pigment epithelial defects in a patient with foreign body sensation and presbyopic complaints. These defects correlate with vision loss and absent choriocapillaris, indicating a significant retinal abnormality.

    Area of Science:

    • Ophthalmology
    • Retinal Diseases
    • Choroidal Vasculature

    Background:

    • Bilateral pigment epithelial defects can manifest with various visual complaints.
    • Symmetrical retinal findings may suggest specific underlying pathologies.

    Purpose of the Study:

    • To investigate the clinical and angiographic findings in a patient presenting with foreign body sensation and presbyopic complaints.
    • To characterize the nature of bilateral, symmetrical pigment epithelial defects.

    Main Methods:

    • Ophthalmoscopy for visual inspection of retinal structures.
    • Visual field testing to assess functional deficits.
    • Electrooculogram (EOG) to evaluate retinal pigment epithelium function.
    • Fluorescein angiography (FA) to visualize choroidal and retinal vasculature.

    Main Results:

    • The patient exhibited bilateral, symmetrical pigment epithelial defects.
    • Visual field defects corresponded precisely to areas of pigment epithelium loss.
    • Electrooculogram results were abnormal.
    • Fluorescein angiography revealed normal large choroidal vessels but absent choriocapillaris in affected regions and abnormal pigment epithelium at defect margins.

    Conclusions:

    • The findings suggest a condition characterized by significant choriocapillaris atrophy and associated retinal pigment epithelial dysfunction.
    • Symmetrical pigment epithelial defects correlating with visual field loss and vascular anomalies warrant further investigation into underlying causes.
