FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to ophthalmology, and can be used to determine progression of advanced glaucoma. Static perimetry and examination of the central field of view are performed according to program 24-2. Average value of light sensitivity from four points is determined: two from the lower nasal sector along the horizontal axis in range from 3° to 9° from the fixation point and two located at 9° from the fixation point on both sides of the vertical axis in the lower half of the field of view (Scp. 1). Average value of light sensitivity from the same points in the mirror located sector of the upper half of the field of view (Scp. 2) is determined. Average value of light sensitivity from two points from the upper and two from the lower half of the field of view with the highest value of light sensitivity (Scp. 3) is determined. If Scp. 1/Scp. 2 is more than 1, the index of advanced glaucoma is calculated as ratio Scp. 2/Scp. 3. If Scp. 1/Scp. 2 is less than or equal to 1, then the advanced glaucoma index is calculated as the ratio Scp. 1/Scp. 3. Examination is repeated not earlier than in 2 months. If the index decreases by more than 0.12, progression of glaucoma is determined.
EFFECT: invention provides the possibility of adequate assessment of functional changes in advanced stage of glaucoma for selection of therapeutic approach due to determination of index of advanced glaucoma.
