Pressure sensing retractor for measuring orbital compartment pressure of an eye

A method of measuring orbital compartment pressure in an eye, comprising:

• (a) having a pressure sensing retractor comprising:
• an inner retractor blade comprising (i) a section with a proximal end and a distal end, and (ii) at the distal end of the inner retractor blade an inner curved retractor blade with an inner radius,
• an outer retractor blade comprising (j) a linear section with a proximal end and a distal end, and (jj) at the distal end of the outer retractor blade an outer curved retractor blade with an outer radius, wherein the outer radius is larger than the inner radius such that the inner curved retractor blade is nested within the outer curved retractor while maintaining a separation distance, and
• a force sensor with a first end and a second end, wherein the proximal end of the outer retractor blade is connected to the second end of the force sensor, and wherein the proximal end of the inner retractor blade is connected to the first end of the force sensor;
• (b) placing the pressure sensing retractor in between an eyelid and a globe of the eye;
• (c) pulling with the inner curved retractor blade the eyelid of the eye;
• and
• (d) touching with the outer curved retractor blade the orbital compartment pressure via the globe of the eye, wherein the touching is registered by the force sensor.
