About

Comparison of intradevice repeatability of thickness measurements for macular area in the eyes with normal and various retinal diseases using SS-OCT and SD-OCT

Full description

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.
