All patients underwent slit-lamp fundoscopy with a +78 D lens and high-definition (HD)-OCT, and the vertical cup disk ratios (VCDRs) were recorded. Disk size and neuroretinal rim assessment were done, and the disk was then staged using the recent version, which stages the optic nerve head (ONH) from 1 to 10 as read from the DDLS nomogram table. DDLS scores &gt;5 indicate glaucomatous damage. Pearson coefficient was used to correlate the DDLS staging by slit-lamp biomicroscopy with best-corrected visual acuity (BCVA), intraocular pressure (IOP), disk size, and VCDR and VCDR, mean deviation, and DDLS staging by HD-OCT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The mean age of the patients was 59.54 \u00b1 6.61 years.

The mean VCDR on 78 D slit-lamp biomicroscopy was 0.76 \u00b1 0.09 (standard deviation [SD]) (range 0.1\u20130.77), whereas on HD-OCT, the mean VCDR was 0.81 \u00b1 0.09 (SD) (range 0.07\u20130.81). The mean deviation on visual field testing in decibels was \u221214.43 \u00b1 3.31 (SD).
