Aims: To determine brake reaction times before and after bilateral cataract surgery in elderly drivers. Methods: Sixty‐four patients were evaluated on the day of and 4 weeks after bilateral cataract surgery. Forty‐three healthy individuals with a valid driving licence served as the control group. A driving simulator was used to determine brake reaction times after receiving a visual stimulus. Total brake reaction time (BRT) as well as neurologic reaction time (NRT), foot transfer time (FTT) and brake pedal travel time (BPTT) were measured, and the measurements obtained before and after cataract surgery were compared. The correlations between NRT, best‐corrected visual acuity (BCVA) and contrast sensitivity (CS) were assessed. Results: Out of the 64 patients with bilateral cataract, 53 were assessed for postsurgical measurements. All time measures improved significantly after cataract surgery (BRT, 815.7(224) versus 647.9(148) ms; NRT, 364.7(91) versus 283.5(44) ms; FTT, 290.8(62) versus 248.6(58) ms; and BPTT, 160.6(96) versus 116.6(72) ms, p < 0.001). The calculated stopping distance improved significantly after surgery (22.3(6) versus 19.9(4) m at 50 km/h). Best‐corrected visual acuity (BCVA) and contrast sensitivity (CS) improved significantly after surgery (0.25(0.2) versus 0.05(0.05), n = 53, p < 0.001; 1.4(0.2) versus 1.6(0.1), p < 0.001, respectively). There was a significant negative correlation between CS and NRT before surgery (r = −0.253, n = 64, p = 0.04, Pearson's correlation). Conclusion: Our findings show a significant effect of CS on neurological BRTs and the corresponding stopping distances. This highlights the importance of presurgical CS evaluation as a critical factor in cataract surgery decisions in elderly drivers. [ABSTRACT FROM AUTHOR]

Background: We investigated effects of submacular fluid volume (SMFV) on visual outcomes following surgery for macula‐off primary rhegmatogenous retinal detachment (RRD) using automated fluid volumetric quantification with optical coherence tomography (OCT). Methods: We analysed 127 eyes that were surgically treated for macula‐off RRDs. We obtained preoperative images following the spectral domain (SD)‐OCT dense volume protocol, applied automated retinal segmentation and used an automated algorithm to quantify each eye's SMFV. We used multivariate models to identify various risk factors for impaired visual outcome. Results: Linear regression showed that preoperative SMFV (ß = 0.013; P =.005) was significantly associated with a reduced visual outcome 12 months after the treatment of macula‐off RRDs. SMFV was negatively correlated with 12‐month postoperative (r =.311; P =.001) visual acuity (VA). The group with low preoperative SMFV (≤9.0 mm3) showed an increasing VA up to 12 months postoperatively (P <.001), while the VA did not increase in the group with high SMFV (>9.0 mm3) beyond 3 months of follow‐up. Patients with a high SMFV were 8.0 times more likely to have worse visual outcomes after 12 months of follow‐up (P =.018). Conclusions: SMFV was negatively correlated with visual outcomes after the surgical treatment of macula‐off RRDs. Patients with SMFV <9.0 mm3 12 months after surgery had an 8.0 times greater chance for better visual recovery than patients with high preoperative SMFV. Our findings highlight the efficacy of automated SMFV quantification in predicting surgical outcomes in patients with RRDs, which could be useful in future clinical practice and the development of research models.
