“…Secondly, we did not follow the remaining 753 subjects who consented for the study but did not encounter any intraoperative complication during their surgery. Previously our centre reported serial macular thickness measurements using SD-OCT in 132 patients who underwent uneventful phacoemulsification [21]. No CMO cases were detected in this series.…”

BackgroundTo report the rate of cystoid macular oedema (CMO) as detected by spectral-domain optical coherence tomography (SD-OCT) after intraoperative complication during phacoemulsification. The secondary objectives include comparing mean macular thickness and best-corrected visual acuity (BCVA) between those who developed postoperative CMO against those who did not.MethodsThis is a prospective cohort study conducted in a tertiary hospital between July 2009 and June 2010. Serial SD-OCT and BCVA were performed at baseline, 1 week, 6 weeks and 16 weeks postoperatively.ResultsSingle eyes from 47 subjects were analyzed; of these 16 (34%) eyes developed CMO. In the CMO group, mean macular thickness (±SD) increased sharply by 56 μm from 273 ± 24 μm at baseline to 329 ± 31 μm at 16 weeks; whereas in the non-CMO group, macular thickness showed a slight increase of 14 μm from 259 ± 21 μm to 272 ± 20 μm. In the CMO group, mean BCVA (in logarithm of minimum angle of resolution) improved modestly from 0.92 ± 0.66 to 0.66 ± 0.41 at week 16; while in the non-CMO group, mean BCVA improved markedly from 0.98 ± 0.59 to 0.21 ± 0.13. The two groups differed significantly in mean macular thickness (p < 0.001) and mean BCVA (p < 0.001) at 16 weeks.ConclusionAs detection rate of CMO is high, postoperative OCT monitoring for patients with intraoperative complications allows earlier diagnosis and treatment.
