PURPOSE: To investigate the effects of pseudophakic cystoid macular edema (PCME) on retinal nerve fiber layer (RNFL) thickness before and after treatment using optical coherence tomography (OCT).
METHODS: A retrospective, observational study of consecutive patients diagnosed with PCME after cataract surgery. Patients underwent macular and RNFL OCT imaging at time of diagnosis and during follow up. OCT was performed for both the study eye and the contralateral healthy eye which served as control. All patients were followed for a period of at least 6 months.
RESULTS: Overall, 40 eyes of 40 patients with a mean age of 71.1 ± 8.1 years of which 45% (n = 18) were of male gender were included in this study. At presentation, the central thickness in the PCME eye was significantly higher than in the contralateral eye (515.7 ± 127.9μm versus 238.1 ± 41.8μm, p < 0.001). Similarly, all macular measurements were significantly higher in the PCME eye compared to the contralateral eye (p < 0.001 for all). In terms of RNFL measurements, the PCME eyes had greater global (p < 0.001), superonasal (p = 0.001) and superotemporal (p = 0.005) thickness values. PCME eyes demonstrated a significant decrease in thickness for all macular and RNFL parameters following resolution of CME (p < 0.05 for all).
CONCLUSIONS: PCME patients presents with greater global, superotemporal and superonasal RNFL thickness in comparison to the other healthy eye. After resolution of PCME, there is significant thinning of RNFL. Peripapillary RNFL thickness may serve as an additional parameter for diagnosis and follow-up of PCME.
