Prostaglandin analogues lower IOP primarily by this mechanism
What is increased uveoscleral outflow?
Vitreous is most firmly attached to the retina at these locations (name >3)
What are the optic disc margin, macula, retinal vessels, vitreous base, and posterior lens capsule?
This technique uses physical pressure on the globe to help differentiate OIS from CRVO

This portion of the TM contributes the greatest amount of resistance to aqueous outflow
What is the juxtacanalicular meshwork?
This PAS-positive layer lies between the RPE and choriocapillaris
What is Bruchs membrane?
If started at an early age, dietary restriction of this can slow progression of gyrate atrophy
What is arginine?
This structure divides the lacrimal gland into orbital and palpebral lobes
What is the levator aponeurosis? (More specifically its lateral horn)
This optic nerve segment is most prone to injury from blunt trauma to the head
What is the intracanalicular segment of the optic nerve?
This is the diameter of the cornea being flattened during Goldmann applanation tonometry

Light-dark reversal on specular microscopy is characteristic of this diagnosis
What is ICE syndrome?
This is the only orbital wall that does not include the sphenoid
What is the orbital floor? (Lesser wing forms part of the roof and medial wall, greater wing forms part of lateral wall)

What are 70% and 30%? (respectively)
Variations in this gene are associated with pseudoexfoliation syndrome
What is LOXL1? (Lysyl oxidase -- role in elastin metabolism)
This pathology is caused by trauma-induced complement activation and leukoembolization

Whitnall's tubercle is the site of attachment for these 4 structures
What are levator aponeurosis (lateral horn), lateral canthal tendon, Lockwood ligament, and lateral rectus check ligament?
These cranial nerves mediate the afferent and efferent limbs (respectively) of the oculocardiac reflex
What are the trigeminal (CN V1) and vagus (CN X) nerves?
