3rd
Glaucoma Epidemology
A.A., older, HTN, Hyperlipidemia, diabetes, systemic vascular dz, Raynauds, alchohol/smoking, FHx
Ocular glaucoma risk factor with RE
Myopia (especially greater than 6D)
Visual acuity and glaucoma
Normally only affected late in the dz
Pupils and glaucoma
Affected late in the disease but occur bilaterally so no relative defects
Steamy cornea with perilimbal injection
Acute angle closure glaucoma
Krukenberg spindle
Pigment. May be pigment dispersion glaucoma
Glaucomfleckin
This is opacification of the lens from high IOP.
Normal IOP
10-21 mmhg.
What IOP pressure alone is enough to start tx?
30 mmhg
Normal corneal thickness
555 nm
____ Corneas underestimate IOP
Thin
____ Corneas overestimate IOP
Thick
Corneal thickness at a high risk
Corneal thickness at a lower risk
> 588
Progressive thinning of _____ is pathonogmonic for glaucoma
Neural rim
Disk size of myopes vs. hyperopes
Myopes have a bigger disc.
As C/D reaches ____ glaucoma risk increases
.6
Is asymmetrical optic discs normal?
NO! Any difference of .1 is abnormal
