Universidade Federal de Pernambuco, Recife, PE, Brazil.
Purpose: The volume of the vitreous chamber varies with the size of the eye. The space created in the vitreous cavity by a vitrectomy is called the vitrectomized space. The volume of the vitrectomized space is strongly correlated with the axial length of the eye.

Under normal conditions, potassium is predominantly found within cells. The concentration gradient of sodium and potassium ions between intracellular and extracellular spaces enables signal transmission through membrane depolarization. The disruption of this transcellular process leads to elevated potassium ion levels in the extracellular space, and thus in the blood, a condition known as hyperkalemia.

Porcine eyes were examined using postmortem computed tomography (PMCT) under controlled postmortem time and temperature conditions to assess the mechanisms and timing of changes in ocular structure. Eight porcine heads were halved, and PMCT scans were conducted from postmortem interval (PMI) days 0 to 13. CT images were obtained to evaluate the vitreous volumes, vitreous CT values, axial lengths of the eyes, lens dislocation, and intraocular gas.
