Summary

The Valsalva manoeuvre can cause preretinal haemorrhage by increasing eye pressure. This condition, Valsalva maculopathy, usually resolves without affecting vision.

Area of Science:

  • Ophthalmology
  • Vascular Medicine

Background:

  • The Valsalva manoeuvre involves forceful exhalation against a closed glottis, increasing intrathoracic and intra-abdominal pressure.
  • This can lead to a rapid rise in intraocular venous pressure.

Observation:

  • A sudden increase in intraocular pressure can cause perifoveal capillaries to rupture.
  • This results in a preretinal haemorrhage, typically located at the macula.

Findings:

  • Valsalva maculopathy is an isolated, self-limited event in otherwise healthy eyes.
  • The haemorrhage usually resolves spontaneously, without permanent visual acuity compromise.

Implications:

  • Understanding Valsalva maculopathy is crucial for diagnosing and managing visual disturbances after strenuous activities.
  • Weightlifting is identified as a potential trigger for Valsalva maculopathy in susceptible individuals.
