Acute macular neuroretinopathy.
An unrecognized acute macular affection occurred in four women, 24 to 35 years old, using oral contraceptives who complained of a sudden decrease of visual acuity or paracentral scotomas. Three patients had bilateral lesions and one patient had unilateral lesions. These lesions consisted of darkish brown-red, wedge-shaped dots in the macula pointing to the fovea. These dots were located mostly on the nasal side to the macula. Biomicroscoby showed these lesions were located in the superficial layers of the retina. The retinal vessels, pigment epithelium, and optic disk showed no distinct pathologic features. Fluorescein angiography, performed repeatedly, showed some questionably dilated perimacular capillaries without leakage in two cases. Static perimetry delineated dense paracentral scotomas. Recovery was slow or absent, confirmed py perimetric observation. Ophthalmoscopic, fluorescein angiography, and perimetric details excluded an affection of the pigment epithelium, the nerve fiber layer, and the optic disk. Since the affection appears to be localized superficially in the retina, we called this specific entity acute macular neuroretinopathy.
