    Ciliochoroidal detachment in monkey eyes increased outflow facility. This suggests fluid flow across the sclera from the suprachoroidal space may be measurable, impacting intraocular pressure regulation.

    Area of Science:

    • Ophthalmology
    • Ocular Physiology

    Background:

    • Ciliochoroidal detachment can alter intraocular pressure dynamics.
    • Understanding outflow facility is crucial for managing ocular conditions.

    Purpose of the Study:

    • To measure total outflow facility in cynomolgus monkey eyes with ciliochoroidal detachment.
    • To investigate the relationship between ciliochoroidal detachment and fluid dynamics.

    Main Methods:

    • Constant pressure perfusion was used to measure outflow facility.
    • Comparison was made between eyes with ciliochoroidal detachment and fellow eyes after sham operation.

    Main Results:

    • Outflow facility was significantly increased in eyes with ciliochoroidal detachment (0.22 +/- 0.04 microliter/min-1/mmHg-1).

  • Intraocular pressure was lower than episcleral venous pressure following detachment.
  • Conclusions:

    • The observed increase in outflow facility may reflect fluid flow from the suprachoroidal space across the sclera.
    • This finding offers insights into the mechanisms of intraocular pressure regulation during ciliochoroidal detachment.
