Topical Serum for Treatment of Keratomalacia
PROCEDURES PRO > OPHTHALMOLOGY > PEER REVIEWED Topical Serum for Treatment of Keratomalacia Amy Knollinger, DVM, DACVO Eye Care for Animals Salt Lake City, Utah Corneal Anatomy An understanding of corneal anatomy is vital to determine if serum therapy for the treatment of keratomalacia should be initiated. The cornea makes up the anterior por- tion of the globe and provides multiple functions for vision: it is transparent (despite originating from surface ectoderm), thereby allowing for clear vision; it acts as the major refractive (bending of light) surface of the globe; and it provides a protective barrier between the globe and the environment The cornea consists of 4 layers in domestic species, being approximately 0.45–0.55 mm thick in the normal dog. The corneal epithelium is the most external layer overly- What You Will Need ing the stromal layer, which accounts for 90% of the total corneal thickness.

Involvement of the Eye in Protein Malnutrition * -303
Bull. Org. mond. Sante 1958, 19, 303-314 Bull. Wld Hith Org. INVOLVEMENT OF THE EYE IN PROTEIN MALNUTRITION * D. S. McLAREN, M.D., Ph.D., D.T.M. & H. Medical Research Officer, East African Institute for Medical Research, Mwanza, Tanganyika Formerly at the MRC Human Nutrition Research Unit, National Institute for Medical Research, London SYNOPSIS An extensive review of the literature on protein malnutrition, with special reference to the frequency of involvement of the eyes, has been made by the author. Consideration of accounts from all parts of the world and in many different languages, including early as well as more recent descriptions of the syndrome, indicates that this important complication has not received sufficient attention hitherto. The evidence available suggests that it is nearly always an accompanying deficiency of vitamin A that is responsible. Less commonly reported-and producing less severe effects-is deficiency of the B-complex vitamins, and there is no clear evidence to date that protein deficiency itself damages the eyes in these cases. The ways in which protein lack might interfere with various aspects of vitamin-A metabolism are discussed, but it is pointed out that their actual significance in human disease is not yet known. A low dietary intake of vitamin A is regarded by the author as being the prime factor in the causation of eye complications, and attention is drawn to the necessity to correct this as part of any prophylactic or therapeutic programme aimed primarily at combat- ing protein malnutrition. The syndrome known by such various names as kwashiorkor, nutritional oedema syndrome, sindrome pluricarencial, and many others (Trowell, Davies & Dean, 1954), and characterized chiefly by a dietary deficiency ofprotein, has been reported as occurring amongst most of the malnourished communities of the world. -

© Alan Macfarlane and Gerry Martin, 2002 MYOPIA: ITS COMPARATIVE INCIDENCE AND PROBABLE CAUSES What Rasmussen encountered in his many years of working with Chinese eye problem astonished him. He summarized his impressions thus. 'Three facts stand out clearly in both ancient and modern records of Chinese eyesight: one that they are a highly myopic nation; two that keratomalacia is the major cause of ocular disease; and three that presbyopia is earlier than in the West by about five years. They stand out against an historical background of neglect and abuse, malnutrition, and centuries of State indifference.' (p.48) Moving on to the statistics of myopia, he summarized the research of a quarter of a century by saying that 'only 20 per cent. of all lenses supplied by the ancients, and similar amount by the moderns (excluding high astigmatic) were for old-sight lenses. It is the other 80 per cent. that matters; the 65 per cent. for myopia and the 15 per cent. for glare and therapeutics.' (p.20) Elsewhere he gives slightly different statistics, which applied to those aged under forty years, showed that approximately 75 per cent. of the lenses were supplied for myopia. In a detailed table he presents the figures; in the 'Ancient Chinese Sight Records', 65% were for myopia; in the 'Modern Chinese Sight Records' myopia (simple) or with astigmatism combined accounted for 70% of the lenses.(p.48) The second figure of 70% was based on 120,000 case histories collected by Rasmussen and his colleagues over a period of 25 years. (p.49) The significance of the degree of myopia only comes out if we compare the Chinese figures with those for other nationalities. -
