Measurement of strabismus in shortened exam lanes versus the 20-foot lane.
The angle of strabismus was compared in 62 patients when measured at 10 feet and in a 20-foot mirrored system, to measurements at 20 feet. Several divergence excess type exodeviations were measured as being significantly less, relative to the 20-foot measurements. High accommodative convergence/accommodation ratio type esotropes were often measured as being significantly higher in the 10-foot room, relative to the 20-foot measurements. Having a shortened or mirrored lane for strabismus measurement could significantly alter the mode of treatment or amount of surgery in strabismus patients and possibly yield a less than optimal result in strabismus management.
