A RETINAL detachment may be called subclinical when its diagnosis cannot generally be made with the usual methods of investigation. The visual field and the central acuity in such cases are not affected by the detachment, although they may be impaired by some other condition, such as lens opacities, blood in the vitreous, areas of chorioretinal degeneration, or glaucoma. The detachment is generally so flat or so peripheral or both that it escapes notice unless a careful and methodical ophthalmoscopic examination is performed under the best possible conditions. The pupil should be fully dilated; the ophthalmoscope light should be the strongest available, and examination should be performed in a dark room with the patient both sitting up and lying down. As subclinical detachments may escape notice because they are often confined to the extreme periphery, this region of the eye should be examined with particular care.
