PURPOSE: To investigate the effects of orthoptic training for residual diplopia after blowout fracture (BOF) surgery.
METHODS: We retrospectively reviewed the medical records of 14 (average age, 22.9 ± 13.1 years) patients with residual diplopia, who had undergone orthoptic training after BOF surgery at the Department of Ophthalmology, Kindai University Hospital, between August 2013 and September 2019. The orthoptic training included exercises for eye movement, convergence, and fusional area expansion. We assessed the training effects by scoring patients' Hess screen (Hess) test results and fields of binocular single vision (BSV). The scores obtained before/after surgery and after training were compared. We also investigated the factors that influenced patients' BSV scores after training. p < 0.05 was considered statistically significant.
RESULTS: The respective pre- and postoperative and after-training average scores were 7.0 ± 5.3, 5.4 ± 4.3, and 2.5 ± 3.2 points for Hess and 50.0 ± 41.3, 48.2 ± 35.9, and 89.4 ± 14.0 points for BSV. Neither Hess nor BSV score showed a significant difference before and after surgery (p > 0.05, the Steel-Dwass test). Compared to the postoperative (i.e., before training) scores, both Hess and BSV scores significantly improved after training (p < 0.05 for Hess, p < 0.01 for BSV; the Steel-Dwass test).
CONCLUSION: Orthoptic training appeared effective in resolving residual diplopia after BOF surgery by improving patients' ocular motility and expanding the BSV field.
