Macular circulation and the flying corpuscles phenomenon

M Loebl, C E Riva

    Ophthalmology
    |September 1, 1978
    PubMed
    Summary

    The flying corpuscles (FLC) test detects leukocyte motion in retinal capillaries, correlating with macular disease. This noninvasive method assesses perifoveal retinal circulation and macular function.

    Area of Science:

    • Ophthalmology
    • Retinal Circulation
    • Medical Diagnostics

    Background:

    • The entoptic phenomenon of flying corpuscles (FLC) involves perceiving leukocytes in perifoveal capillaries.
    • Understanding FLC motion provides insights into retinal microcirculation.

    Observation:

    • A novel method was developed to analyze FLC motion characteristics, including speed, number, and distribution.
    • This technique was applied to 38 patients with macular diseases.

    Findings:

    • FLC analysis results showed strong correlation with clinical findings from ophthalmoscopy, visual field tests, and fluorescein angiography.
    • The study successfully characterized perifoveal retinal circulation and macular function in patients.

    Implications:

    • The developed FLC test is noninvasive, inexpensive, and easy to perform.
    • This method offers valuable diagnostic information for macular diseases.
    • It serves as a new tool for assessing perifoveal retinal circulation and overall macular function.
