What is the appearance of Schwalbe’s line and where does it sit within the anterior chamber?
A white/translucent line marking the end of the cornea at Descemet’s membrane
If Schwalbe’s line is pigmented, what is it known as?
Sampolesi’s line
What is the appearance of the trabecular meshwork and where does it sit within the anterior chamber?
Translucent/grey/brown line between Schwalbe’s line and the scleral spur
What is the appearance of the ciliary body and where does it sit within the anterior chamber?
Black/grey/brown and only visible if wide angle between the iris root and scleral spur
What is the appearance of the scleral spur and where does it sit within the anterior chamber?
Bright white line between the trabecular meshwork and the ciliary body
What is the appearance of the Canal of Schlemm and where does it sit within the anterior chamber?
Not normally visible, only if filled with blood. Found between trabecular meshwork and scleral spur
