Lacquer crack lesions in pathologic myopia.

R M Klein, B J Curtin

    American Journal of Ophthalmology
    |March 1, 1975
    PubMed
    Summary
    This summary is machine-generated.

    Lacquer cracks in young adults indicate mechanical breaks in the eye's inner layers. These findings suggest a guarded prognosis for maintaining central vision in affected individuals.

    Area of Science:

    • Ophthalmology
    • Retinal Diseases
    • Ocular Anatomy

    Background:

    • Lacquer cracks are observed in eyes with posterior staphylomas and increased axial lengths.
    • These lesions are associated with visual impairment, including decreased visual acuity and altered visual fields.

    Purpose of the Study:

    • To evaluate the anatomic and functional characteristics of lacquer cracks.
    • To understand the underlying pathology and implications for visual prognosis.

    Main Methods:

    • Clinical evaluation of 22 eyes from 14 patients with lacquer cracks.
    • Assessment of visual acuity, visual fields, and associated ocular findings.
    • Fluorescein angiography to characterize lesion appearance.

    Main Results:

    Related Experiment Videos

    • Lacquer cracks were found in young adults with posterior staphylomas and elongated eyes.
    • Most patients experienced decreased visual acuity and visual field defects.
    • Associated findings included choroidal hemorrhage and chorioretinal atrophy in some cases.
    • Fluorescein angiography showed characteristic early and late staining patterns.

    Conclusions:

    • Lacquer cracks likely represent healed mechanical breaks in the retinal pigment epithelium-Bruch's membrane-choriocapillaris complex.
    • The presence of lacquer cracks suggests a guarded prognosis for preserving central vision.
