Wide-field retinal nerve fiber layer maps using swept-source optical coherence tomography showed increased ability to detect signs of early glaucoma as compared with the conventional OCT parameters, namely circumpapillary RNFL thickness measurement and ganglion cell analysis.
In a retrospective study, 43 eyes with preperimetric glaucoma, 74 eyes with early perimetric glaucoma and 67 heathy eyes were imaged by SS-OCT using a wide-field single scan protocol. This allowed the imaging of a large, 12 x 9 mm area including the macula and optic nerve in a single scan of only 1.3 seconds. Conventional circumpapillary retinal nerve fiber layer (cpRNFL) thickness and macular ganglion cell measurement were also performed.
