OBJECTIVE: To evaluate the effect of the Valsalva maneuver (VM) during micturition on intraocular pressure (IOP) in patients with benign prostatic hyperplasia (BPH).
PATIENTS AND METHODS: IOP were measured before and during micturition in uroflowmetry testing by Tonopen-Avia (Reichert Inc., NY, USA) in 35 eyes of 35 patients with BPH. International Prostate Symptoms Score (IPSS) questionnaire was used for quantification of BPH symptoms. The subjects were divided into two groups according to IPSS questionnaire: patients with low IPSS scores and patients with high IPSS scores.
RESULTS: The mean IOP before and during micturition in patients with BPH were 15.26 ± 4.39 mmHg and 16.23 ± 4.43 mmHg, respectively (p = 0.047). When patients with BPH were assigned to two distinct groups according to the IPSS scores, IOP did not differ in patients with low IPSS scores (p = 0.590), whereas mean IOP was significantly higher in patients with high IPSS scores (p = 0.007).
CONCLUSIONS: The Valsalva maneuver, performed during micturition, can lead to significant IOP increase in patients with BPH, particularly in advanced disease.Free PDF Download
