Purpose: To detect any choroidal thickness (CT) change in patients after alpha-lytic drugs withdrawal that could help in the cataract surgery timing decision. Methods: Twenty-five eyes of 25 patients (mean age: 76 ± 7 years) under alpha-lytic therapy, and 25 eyes of 25 control subjects (CS) (mean age: 75 ± 7 years) without alpha-lytic therapy, both scheduled for cataract surgery in the fellow eye, were included in this observational, prospective, non-randomized study. All patients underwent EDI-OCT during the first preoperative visit and approximately 1 month (range 28–31 days) after alpha-lytic withdrawal. In the CS group, the OCT during preoperative visit and approximately 1 month after (range 28–31 days) the first examination was performed. Data normality with Kolmogorov-Smirnov test was checked and statistical evaluation with the Wilcoxon-signed rank test was performed. Results: The mean subfoveal CT was 224 ± 79.7 μm during therapy and 217 ± 70.4 μm after withdrawal; 1.5 mm nasally from the fovea CT was 198 ± 83.8 μm and 194 ± 82.8 μm, respectively; and 1.5 mm temporally from the fovea CT was 217 ± 55.9 μm and 205 ± 54.4 μm, respectively. A statistically significant reduction (p < 0.05) in all the 3 measured CT points was found. In the CS no significant changes were detected (p > 0.05). Conclusion: No severe floppy iris syndrome was detected at the time of surgery. In these patients, CT decrease could be an important sign for cataract surgery timing decision.

Abstract
Purpose: To detect any choroidal thickness (CT) change in patients after alpha-lytic drugs withdrawal that could help in the cataract surgery timing decision. Methods: Twenty-five eyes of 25 patients (mean age: 76 ± 7 years) under alpha-lytic therapy, and 25 eyes of 25 control subjects (CS) (mean age: 75 ± 7 years) without alpha-lytic therapy, both scheduled for cataract surgery in the fellow eye, were included in this observational, prospective, non-randomized study. All patients underwent EDI-OCT during the first preoperative visit and approximately 1 month (range 28–31 days) after alpha-lytic withdrawal. In the CS group, the OCT during preoperative visit and approximately 1 month after (range 28–31 days) the first examination was performed. Data normality with Kolmogorov-Smirnov test was checked and statistical evaluation with the Wilcoxon-signed rank test was performed. Results: The mean subfoveal CT was 224 ± 79.7 μm during therapy and 217 ± 70.4 μm after withdrawal; 1.5 mm nasally from the fovea CT was 198 ± 83.8 μm and 194 ± 82.8 μm, respectively; and 1.5 mm temporally from the fovea CT was 217 ± 55.9 μm and 205 ± 54.4 μm, respectively. A statistically significant reduction (p < 0.05) in all the 3 measured CT points was found. In the CS no significant changes were detected (p > 0.05). Conclusion: No severe floppy iris syndrome was detected at the time of surgery. In these patients, CT decrease could be an important sign for cataract surgery timing decision.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
