METHOD FOR REMOVING CENTRAL SCOTOMA AT AMBLYOPIA AT NONCENTRAL FIXATION Russian patent published in 2004 - IPC

FIELD: medicine, ophthalmology.

SUBSTANCE: daily before the first seance one should illuminate foveola of nonamblyopic eye, moreover, a patients observes positive successive image and marks the period of its existence. Foveolic illuminations both in amblyopic and nonamblyopic eyes should be carried out with a hand-operated ophthalmoscope at direct ophthalmoscopy; angular value of illuminated field should be altered depending upon the character of visual fixation, illumination occurs for 20-30 sec. Foveolic illuminations of amblyopic eye should be performed so, that noncentral fixing section to be beyond the area of light stimulation. After illumination patient should close eye to observe the appeared transfoveal positive successive image. Illuminations should be repeated 3-7 times during one seance, moreover, every subsequent illumination should be performed after observed image disappearance in an amblyopic eye or in case if after illumination there is no positive successive image in an amblyopic eye in time period being equal to that of existence of positive successive image in a nonamblyopic eye of a certain patient, moreover, total duration of a seance corresponds to 10-20 min. One should conduct 2-3 seances daily, interval between seances corresponds to 20-30 min, and to detect the terms to finish therapy one should perform illumination of an amblyopic eye before the first seance by a certain technique (in case of extramacular visual fixations) or detect the availability of Haidinger's phenomenon (in case of intramacular visual fixations). At intramacular noncentral visual fixations foveolic illumination should be carried out at angular value of illuminated field being equal to 6 deg. and below, therapy should be finished at availability of Haidinger's phenomenon at a maculotester. In case of extramacular visual fixations foveolic illumination should be carried out at angular value of illuminated field being above 6 deg., and therapy should be finished at availability of clarified section in negative successive image observed after illumination by certain technique.

EFFECT: increased efficiency.
