<unk> s are often readily observed by an ophthalmologist or an optometrist with the use of an ophthalmoscope or slit lamp. However, if the<unk>  is near the retina, it may not be visible to the observer even if it appears large to the patient. Increasing background illumination or using a pinhole to effectively decrease pupil diameter may allow a person to obtain a better view of his or her own<unk> s. The head may be tilted in such a way that one of the<unk> s drifts towards the central axis of the eye. In the sharpened image the fibrous elements are more conspicuous. The presence of retinal tears with new onset of<unk> s was surprisingly high (14%; 95% confidence interval, 12–16%) as reported in a meta-analysis published as part of the Rational Clinical Examination Series in the Journal of the American Medical Association. Patients with new onset flashes and/or<unk> s, especially when associated with visual loss or restriction in the visual field, should seek more urgent ophthalmologic evaluation.
