Diffuse corneal edema a severe corneal edema may be confused with anterior chamber opacity but corneal stromal connective tissue thickening keratoconus degenerative noninflammatory disorder of the eye and corneal bullae fluidfilled blister are more typically noted with diffuse corneal edema than with hypopyon or lipid flare

What is the correctly punctuated version of this sentence?
Diffuse corneal edema, a severe corneal edema, may be confused with anterior chamber opacity, but corneal stromal (connective tissue) thickening, keratoconus (degenerative non-inflammatory disorder of the eye), and corneal bullae (fluid-filled blister) are more typically noted with diffuse corneal edema than with hypopyon or lipid flare.
