摘要:

The elderly population will substantially increase by the year 2000, leading to an increased number of elderly patients in the op-tometric practice. The elderly differ substantially from other patient groups as aging is accompanied by many functional deficits. However, the majority of these decrements do not result in illness or disability. Disease states exist separately or are superimposed upon the already compromised body systems of the elderly. The average geriatric patient suffers from two or more chronic diseases. As primary care practitioners, optometrists should be familiar with the more prevalent diseases of the elderly and their impact upon performance during the vision examination. A review of the common diseases associated with aging is presented

摘要:

The photograph illustrates persistence of fibroglial remnants of the posterior hyperplastic primary vitreous, or Bergmeister's papilla, in the right eye of a 12-year-old boy. Vision of this eye was 6/9 and there was no detectable visual field loss. The left eye was normal Bergmeister's papilla contains the embryonic vascular and fibroglial material from which the hyaloid artery and central retinal artery systems develop. Developmental abnormalities may occur in any portion of the hyaloid system, from the tunica vasculosa lentis anteriorly, to Bergmeister's papilla at the optic disc. Normally the hyaloid artery resorbs at about the 7th month of gestation.1Persistence of portion of the posterior primary vitreous results in a number of anomalies, the most common of which are epipapillary glial membranes that are seen in 6.6% of clinic patients2and vascular loops on the disc. The condition illustrated is an uncommon and more extreme form of persistence of fibroglia. Strands of this tissue may attach to the inner limiting membrane of the peripapillary and more peripheral retina1and may proliferate, or persist as preretinal fibroglial tufts,3as in this illustration. The tufts are seen to be associated with retinal blood vessels and also as isolated bands radiating from the disc. Additional amorphous glial remnants are situated in the vitreous over the disc and partly obscure its features The congenital anomaly is commonly associated with disturbed macular function4and shrinking of the glial strands may result in retinal folds and detachment.5In this illustration there is an unusual heightening of the reflex from the internal limiting membrane, suggesting that there is traction on the retinal - vitreous interface The differential diagnosis should include medullated nerve fibers, glioma of the optic never head,6and trauma.
