Muscae Volitantes (Muscae Volitantes) - Spots before the Eyes.
- RUDDOCK.E.H,
DEFINITION. - An appearance before the vision as of black motes; or of thin grey films, like the wings of a fly; or half- transparent grey threads, like spiders' webs; or if viewed against a white wall, or other clear and near object, they appear as one of a number of small circles with a central aperture. They depend probably upon minute remains of the embryonic tissue in the vitreous humour.
Mouches volantes have no clinical importance. They do not interfere with the acuteness of vision. Those annoyed with them are strongly recommended not to look for them, as in that case others are very apt to become visible.
CAUSES. - The exciting causes of these ocular spectres are chiefly the following short sight (myopia), excessive use of the eyes, especially in artificial light, or in badly-ventilated rooms; insufficient sleep; certain fevers, as Typhus and Enteric; deranged digestion; Hypochondriasis; morbid sensibility of the general system from business or family cares, or mental distress. A hypochondriacal person having once detected muscae, takes such frequent notice of them that they become a subject of great anxiety.
TREATMENT. - Hyos., Bell., Cocc., Coni., Merc.-Cor., Zinc.
ACCESSORY MEANS. - Treatment must be mainly directed to detecting and removing the exciting cause. If the eyes have been overstrained, rest is essential; entire or partial relief from ordinary daily duties; daily moderate out-of-door exercise in country or sea air; a regulated, nourishing diet; and bathing of the eyes, with cold water, for two or three minutes, several times daily. If muscae are very troublesome, blue glasses should be worn to render them less apparent.
