Design outcomes

Primary

Measure	Time frame
The macular vessel density is measured using optical coherence tomographic angiography at the retinal nerve fiber–ganglion cell–inner plexiform layer, retinal nerve fiber–ganglion cell layer, retinal nerve fiber layer, ganglion cell–inner plexiform layer, ganglion cell layer, and inner plexiform layer segments.	—

Secondary

Measure	Time frame
The macular vessel densities in six segments are compared between glaucoma patients and normal controls.	—

Countries
