Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators studied the intradevice repeatability of thickness measurements for total retina, retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform (GC-IPL) layers of macular area in the eyes with normal and various retinal diseases using SS-OCT and SD-OCT and compared the repeatability between two devices.
