The term cross-eye, or squint, is applied to a condition in which one eye is drawn in toward the nose. When the eye is turned toward the outer comer, the condition is one known as wall-eye. Inward, or converging squint, generally begins in early childhood. The squint is usually the result of long-sightedness, being occasioned by the constant strain necessitated in viewing near objects. At first, this affection is accompanied by double vision; that is, the patient sees two objects where but one exists. After some time, however, but one object is seen, as the squinting eye is not used in viewing objects, in consequence of which the power of sight is gradually lost. The immediate cause of strabismus is the weakening of one or more of the muscles of the eyeball. This may be the result of paralysis of some of the muscles of the eyeball. Squint sometimes appears very suddenly. In such cases, it is generally indicative of disease of the brain, as in meningitis and tumors of the brain.

The Treatment of Cross Eye - Wall Eye - Squint - Strabismus

When due to paralysis, the difficulty may often be relieved by the local application of electricity. The negative pole should be placed over the closed eye, or at the inner side of the nose, the positive being placed upon the forehead just above the eye. In many cases it is necessary to perform an operation upon the eye, which consists in completely or partially dividing the muscle upon the side of the eyeball toward which the eye turns.
