Changes in retinal nerve fibre layer thickness and central sub field macular thickness.

Serial number	Time period from the day of occurrence of CRAO	Average retinal nerve fibre layer thickness (µm) OD	Average retinal nerve fibre layer thickness (µm) OS	Retinal nerve fibre thickness at sample 60 (µm) OD	Central subfield macular thickness (µm) OD
1	Day 3	64	91	217	664
2	Day 7	55	92	64	91
3	Day 30	86	91	123	134
4	Day 90	41	92	42	184

CRAO, Central retinal artery occlusion. Table shows average retinal nerve fibre layer thickness in the affected right eye and normal left eye. Retinal nerve fibre thickness at sample 60 and central subfield macular thickness of the affected eye are also shown. Occurrence of ischaemia-reperfusion retinal injury after day 3 is observed as decrease in retinal nerve fibre thickness at sample 60 leading to final atrophy at day 90.
