Abstract Purpose: The efficacies of prism adaptation test (PAT) and monocular occlusion (MO) and their optimal test durations to detect the maximum angles of deviation at near and distance in eyes with intermittent exotropia (IXT) were assessed and compared. Methods: We retrospectively reviewed the medical records of 72 patients with IXT, who had undergone the initial strabismus surgery between April 2015 and October 2018 and had been preoperatively tested by PAT and MO. The near and distance deviations measured after 30- and 60-minute PAT and MO were compared with the baseline measurements obtained immediately after prism wear and before occlusion. The measurements and the required durations for obtaining the maximum deviation angle were also compared between PAT and MO. Results: Compared with the baseline, the near deviation by PAT significantly increased after 30 (p < 0.05) and 60 (p < 0.01) minutes but not the distance deviation. Besides, the increase in the near deviation after 30 minutes was not significant. By MO, neither near nor distance deviation showed a significant difference from the baseline after 30 and 60 minutes. While the near deviations by PAT were significantly greater than those by MO at 30 and 60 minutes, a similar result was only observed at 30 minutes in the distance deviation. Conclusion: A 30-minute PAT appears to be more effective than MO in revealing the maximum angle of deviation before strabismus surgery.

Purpose:To evaluate changes in ocular motility deviation with cycloplegic eye drop examination compared to the prism adaptation test in patients with strabismus.Methods:The medical charts were reviewed of all patients who underwent primary strabismus surgery in our center from December 2013 to July 2015. Data collected included demographics, medical history, and findings on pre-operative ophthalmic/orthoptic examination. Ocular motility deviation was measured before instillation of cycloplegic eye drops, immediately after maximal dilation (end point), and 10 and 20 min later. Prism adaptation test readings were taken at baseline, immediately after prism removal (end point), and 10 and 20 min later.Results:A total of 43 patients had complete pre- and post-operative evaluations. Our analysis focused only on the exotropic patients (n = 33). On cycloplegics, there was no significant difference in ocular motility deviation between baseline and end point for distance and near (p = 0.584, p = 0.468, respectively). On prism adaptation test, comparison of ocular motility deviation between baseline and end point was statistically significant for distance and near (p = 0.002, p = 0.001, respectively). Changes remained significant 10 min after the end point for near (p = 0.011). Comparison at the end points between the tests revealed statistical significance for distance and near, favoring the prism adaptation test (p = 0.001 and p < 0.001, respectively). This significance was maintained even after 10 min for near (p = 0.036).Conclusion:The prism adaptation test is preferred over cycloplegic eye drops for the evaluation of maximal reserve of distance/near motility before surgical correction of exotropia.

314 Background: The useof intraoperative blood transfusions (IBT) has been associated with worse surgical outcome in patients undergoing liver resection for malignancy. However, detailed analyses are required to define clinical findings impacting short-term outcome in this scenario.The aim of this study is to evaluate whether IBT are associated with a worse short-term outcome of liver resection in patients with colorectal hepatic metastases, and to assess whether certain patient characteristics and/or surgical variables affect the need for IBT. Methods: In a series of 127 consecutive patients who underwent partial liver resection for colorectal metastases, between July 1999 and March 2010, we studied postoperative 90 days surgical outcome relative to IBT, and the effect of a variety of factors, including type of resection, surgical technique used, concomitant colo-rectal resection, non-tumoral hepatic histological findings, site of primary tumor, and comorbidities, on the incidence of IBT. Results: Patients who received IBT during their liver resection were more likely to have a longer postoperative length of stay (p = 0.02), to experience complications (p = 0.0003), and to experience a Clavien Grade IIIa or worse complication (p = 0.003). Furthermore, undergoing a major resection, and the presence of portal fibrosis in the non-tumoral liver were both correlated with an increase in IBT (respectively, p = 0.003 and p = 0.049), while the surgical technique used (Kellyclasia or TissueLink), the presence of steatosis, undergoing a concomitant major colonic or rectal resection, and having a major comorbidity had no effect on the incidence of IBT (p ≥ 0.05). Conclusions: This study confirmed that receiving IBT during partial liver resection for colorectal hepatic metastases is associated with a worse short-term surgical outcome. These clinical findings suggest that although several significant factors (surgical technique chosen, comorbidities present, etc.) do not seem to influence the short-term outcome of surgery, it is important to be aware of the deleterious effects of the type of resection performed and the presence of portal fibrosis on blood loss during partial liver resection.
