Summary

Cardiopulmonary bypass during heart surgery did not significantly alter choroidal thickness or ocular pulse amplitude. However, intraocular pressure decreased post-operatively, indicating potential hemodynamic effects on ocular pressure.

Area of Science:

  • Ophthalmology
  • Cardiovascular Surgery
  • Ocular Physiology

Background:

  • The choroid, vital for retinal blood supply, may be impacted by hemodynamic shifts.
  • Cardiopulmonary bypass (CPB) induces significant hemodynamic alterations.

Purpose of the Study:

  • To investigate changes in choroidal thickness and ocular pulse amplitude (OPA) following CPB.
  • To assess the impact of CPB on ocular hemodynamics and choroidal blood flow.

Main Methods:

  • Prospective study of 42 patients undergoing heart surgery with CPB.
  • Sub-foveal choroidal thickness measured via spectral domain optical coherence tomography.
  • OPA, a surrogate for choroidal blood flow, measured using dynamic contour tonometry.

Main Results:

  • No statistically significant changes in sub-foveal choroidal thickness or OPA were observed post-CPB.
  • No significant correlation found between CPB duration and changes in choroidal thickness or OPA.
  • A significant decrease in intraocular pressure was noted at post-operative follow-ups.

Conclusions:

  • Sub-foveal choroidal thickness and OPA remain stable after CPB.
  • Intraocular pressure shows a notable decrease one week and one month post-CPB.
