The change of retinal layer thickness in Area 2 and 3 during follow-up period The retinal layer thickness was measured using optic coherence tomography. The (a) total, (b) inner and (c) outer retinal thickness tended to increase after surgery, but there was no significant difference between Area 2 and 3 at all follow-up time points. (d) RNFL thickness tended to increase in both Area 2 and 3 at post-operative 1 and 3 months but decreased at post-operative 6-months only in Area 3. However, the change of RNFL thickness was not significantly different between Area 2 and 3. (e) Gc-IPL thickness in Area 3 decreased at post-operative 1-, 3- and 6-months. The change of Gc-IPL thickness in Area 3 was significantly different compared to Area 2 at post-operative 3- and 6-months (Area 2 vs. 3: post-operative 3 months, p = 0.01; post-operative 6 months, p = 0.05). (f) There was no significant difference in changes of RPE layer thickness between Area 2 and 3 at every follow-up time points
