Abstract
Background: Prismatic cover test (PCT) is a gold standard assessment of strabismus angle, however it has a significant number of disadvantages which are eliminated in Strabiscan device.
Methods: Patients with strabismus (n = 30) and a group of healthy subjects (n = 30) were given a detailed history and underwent ophthalmologic examinations (best corrected visual acuity assessment, cycloplegic autorefractometry, biomicroscopic examination of anterior and posterior part of the eye). Each patient and healthy subjects were then subjected to the PCT, and then the presence of strabismus was detected, and its angle assessed using a Strabiscan demonstrator. Statistical analysis was done with Statistica software.
Results: No statistically significant differences were noted in the measurements of strabismus angles made by the differing methods. Among the control group, using the Strabiscan demonstration device, low-angle latent strabismus ≤3PD was diagnosed in 83% of patients, and >3PD in 13% of patients. Those using the PCT, on the other hand, diagnosed latent strabismus ≤3PD in only 13% of patients, and latent strabismus with an angle >3PD in 13% of patients.
Conclusion: The Strabiscan demonstration device provides quick and accurate assessment of the strabismus angle.
