Comparison of Three Clinical Stereoscopic Methods for Measuring Binocular Visual Function During Amblyopic Treatment in Unilateral Amblyopia
Published on: September 27, 2024
Objective:
to investigate the effectiveness of the method of "dissociation" for concomitant strabismus treatment, which involves laser speckles and polaroid separation of visual fields.
Material And Methods:
A total of 40 patients with different types of concomitant strabismus and the average age of 9.8 years were enrolled. The treatment method implies the use of the Forbis device with polaroid separation of visual fields and low-energy helium-neon laser speckle patterns (green and red, 0.53 pm and 0.65 pm correspondingly). Binocular vision recovery was performed in the conditions of alternating exertion and relaxation of accommodation obtained through plus and minus spherical lenses.
Conclusions:
The method ensures an increase in the number of individuals capable of stereopsis from 31.2-44.4% (conventional treatment) to 54.4% as well as widening of the range of tolerated plus/minus spherical lenses, in which the binocular fusion is retained at the same degree of convergence.
