Summary
Brief summary
Intraocular pressure (IOP) depends on the balance between humoral fluid production and drainage, and different pressures can be measured between the right and left eyes with stimuli causing sympathoadrenal stimulation such as laryngoscopy and endotracheal intubation (about 5 min).

It has been aimed to investigate how does spinal anesthesia change the intraoculary pressure.
