Goldmann applanation tonometry is most likely to OVERESTIMATE true IOP in which situation?
Answer: Thick central cornea
A thick central cornea resists applanation, so the reading comes out falsely high.
Which peripapillary RNFL quadrant/sector most commonly shows the earliest glaucomatous thinning on OCT?
Answer: Inferotemporal
The inferotemporal arcuate bundles are most vulnerable early, consistent with the ISNT rule being violated inferiorly.
The Glaucoma Hemifield Test on Humphrey perimetry primarily evaluates:
Answer: Asymmetry between mirror-image superior and inferior sectors
GHT compares five mirror-image sector pairs across the horizontal meridian to detect glaucomatous asymmetry.
On gonioscopy, a scalloped pigment line anterior to Schwalbe line (Sampaolesi line) is most characteristic of:
Answer: Pseudoexfoliation syndrome
Sampaolesi line is classic for pseudoexfoliation, though it can also appear in pigment dispersion.
A patient with a dense superior paracentral scotoma near fixation on 24-2 testing should additionally undergo which test for better characterization?
Answer: 10-2 visual field
The 10-2 has 2-degree spacing that better detects and monitors central/paracentral glaucomatous damage.
Low corneal hysteresis measured by the Ocular Response Analyzer is associated with:
Answer: Higher risk of visual field progression
Lower corneal hysteresis is an independent risk factor for glaucoma progression.
A -9.00 D myope has OCT RNFL flagged red temporally-superiorly but has a normal visual field and healthy-appearing disc. The most likely explanation is:
Answer: Myopic shift of RNFL peaks causing a normative database artifact
In high myopia the RNFL bundles shift temporally and the normative database is inappropriate, producing 'red disease' false positives.
