ABSTRACT Purpose: To evaluate macular ganglion cell complex (GCC) thickness and peripapillary retinal nerve fiber layer (RNFL) thickness in patients treated with SSRIs. Methods: The present study included 62 eyes of 31 patients who were using SSRIs and 60 eyes of 30 healthy, age- and gender-matched control subjects. All patients underwent a full ophthalmological examination in which macular thickness, GCC thickness, and peripapillary RNFL thickness were measured using optical coherence tomography (OCT). The Mann–Whitney U test was used to compare the patients’ group with the age- and gender-matched control group. Pearson correlation analyses were also performed to assess the relationships between macular thickness, GCC thickness, RNFL thickness, and the duration of SSRI usage. Results: The mean duration of SSRI usage was 29.96 ± 27.19 (range 6–120) months. The foveal thickness was 253.48 ± 22.77µm in the patients’ group and 266.60 ± 20.64 µm in the control group; the difference between the groups was statistically significant. In addition, the perifoveal GCC thickness in the inferonasal and inferotemporal quadrant were significantly smaller thinner in the patient group (Mann–Whitney U test, p = 0.021and p = 0.013, respectively). Conclusions: Our results suggest a relation between SSRIs and decreased retinal GCC thickness and RNFL thickness. Future long-term prospective studies should elucidate the actual effect of SSRIs on GCC and RNFL thickness.
