The effects of absence of stereopsis on performance of a simulated surgical task in two-dimensional and three-dimensional viewing conditions.

Bloch E, Uddin N, Gannon L, Rantell K, Jain S - Br J Ophthalmol (2014)

Bottom Line: The stereo-normal group scored higher, on average, than the stereo-absent group with both eyes open under direct vision (p<0.001).Both groups performed comparably in monocular and binocular monitor viewing conditions (p=0.579).High-grade stereopsis confers an advantage when performing a fine motor task under direct vision.

BJOPHTHALMOL2013304517F5: Task performance under monitor vision. Median (squares), 1st–3rd quartile (boxes) and minimum/maximum (error bars).

Mentions: Under monitor (2D) viewing conditions, we found no statistical difference in average number of balls placed within or between groups. Pairwise comparison within the multilevel model demonstrated that stereo-normal group performance with both and one eye open (6.6±0.37 and 6.3±0.32 balls, respectively) was comparable to that of the stereo-absent group (6.0±0.50 and 6.3±0.44 balls), with an estimated difference of means of 0.29 (95% CI −0.70 to 1.28) and p=0.579 (figure 5, table 3).
