Elevated IOP following a bladder filling protocol: A case report.

It was already known that intraocular pressure (IOP) can fluctuate in response to various physiological conditions. However, the specific relationship between hydration protocols and IOP elevation remained unclear. Prior research has shown that oral water intake can influence systemic and ocular hemodynamics. No prior work had resolved how bladder filling might affect IOP in patients with normal baseline pressures. This gap motivated a closer examination of hydration practices in clinical settings. Radiation therapy protocols often include hydration steps to protect organs, but their ocular effects had not been studied. This uncertainty drove the investigation into whether water boluses could elevate IOP. The case report provides new insight into a potential risk factor for glaucoma suspects.

The aim of this report was to investigate a case where elevated IOP followed a bladder-filling protocol. The specific problem addressed was whether hydration practices could trigger IOP elevation in individuals with normal baseline pressures. The motivation stemmed from a patient presenting with acute symptoms after radiation therapy hydration. The study sought to determine if a water bolus could cause transient IOP elevation. It also aimed to assess the utility of the water-drinking test in diagnosing outflow resistance. The researchers proposed to evaluate whether hydration could serve as a provocative test for glaucoma suspects. The study focused on whether hydration practices might contribute to ocular hypertension. This case highlights the need to consider hydration protocols in glaucoma risk assessment.

The study involved a single patient with a history of hypertension and prostate cancer undergoing radiation therapy. The patient consumed a water bolus to fill his bladder before treatment. Intraocular pressure was measured before and after hydration. A water-drinking test was performed to assess IOP fluctuations. Gonioscopy was used to evaluate the anterior chamber angles. Fundus examination assessed optic nerve health and retinal venous tortuosity. Topical IOP-lowering medications were administered to assess responsiveness. The results were compared to baseline measurements to determine the impact of hydration.

The patient exhibited elevated IOP following the water bolus ingestion. Baseline IOP was within normal limits before hydration. After the bolus, IOP increased bilaterally but more significantly in the left eye. The right eye showed a 5 mmHg increase to 20 mmHg. The left eye demonstrated an 8 mmHg increase to 23 mmHg. Gonioscopy confirmed open angles in both eyes. Fundus exam revealed non-glaucomatous optic nerves with retinal venous tortuosity. The patient responded to topical IOP-lowering medications, indicating reversible elevation.

The authors proposed that hydration protocols may elevate IOP in some individuals. This case suggests a potential risk factor for glaucoma suspects. The water-drinking test may have diagnostic value in assessing outflow resistance. The left eye showed greater IOP elevation than the right, indicating asymmetry. The patient’s symptoms resolved with IOP-lowering therapy, supporting the hypothesis. The study highlights the need to consider hydration practices in glaucoma risk assessment. The water-drinking test may serve as a provocative test for at-risk patients. Further research is needed to confirm these findings in larger populations.
