Ocular Disease II Mt 2

Describe why pts may be mis-diagnosed with ocular HTN & LTG based on their corneas.

What is the equatio for ocular perfusion (OP)?

Small scleral canals tend to be related to what type of refractive error?

Indicate which areas of the lamina cribosa tend to have larger pore size.

Where is there the greatest overlap of receptive fields?

Most early VF loss in GLC occurs in the periphery and progresses centrally, eventually leading to blindness if left untreated.

Indicate all the signs/symptoms associated with DIFFUSE axon loss.

You do not need an increase an IOP or VF loss to diagnose GLC.

GLC functional changes can precede structural damage by years

1 tonometry reading has low sensitivity and relatively high specificiy

Which of the following GLC meds does not work at night?

Which ethnicity is the strongest risk factor for developing 'normal tension' GLC?

Which of the following systemic disease results in slower recycling of mucopolysaccharides in the TM endothelium and subsequent increase in IOP?

Corneal edema will result in false ____ IOP

I-Care tonometry has many advantages including: no anesthetic needed, portable, less affected by biomechanical factors compared to NCT

Thicker corneas will have a false high IOP reading on GAT.

1 mmHg increase in IOP results in ___% increased risk for GLC damage

For every microns thinner CCT than normal, there is a % increased risk for GLC damage.

What is the standard of care in GLC detection & management?

One advantage of FDT/Matrix perimeters is that they are better at detecting change in VFs since GLC VF loss gets 'deeper' (less sensitive) as it progresses.

What is the minimum number of VFs that should within the 1st 2 years of GLC diagnosis?

What is the most common mode of GLC progression?

Where are paracentral scotomas most likely to appear in early GLC VF loss (in terms of VF, not retina)?

Nasal steps do NOT cross horizontal midline

Which area of the ON is focal damage most likely to occur?

Cupping precedes pallor in GLC

What % of normal pts have C:D > 0.7?

Zone Alpha is more peripheral than Zone Beta

Parapapillary atrophy represents extensive damage to the ONH.

Like many signs of GLC, drance hemes are not highly specific to GLC

____% of eyes w/ drance hemes will develop VF loss progression over the next 16 mo

Indicate ALL of the DDx's for drance hemes

It is best to look for RNFL drop out with the slit lamp under high mag so you can determine whether or not the fine striations are present or absent,

Which of the following does NOT require treatment (assume the signs below are the only evidence you are basing you decision from).
