To examine subfoveal and peripapillary choroidal thickness changes after successful phacoemulsification in cataract cases with nonglaucomatous pseudoexfoliation syndrome (PXS).
Materials and Methods:
Nineteen cataract patients with PXS and 19 without PXS were included in this prospective and interventional controlled study. Subfoveal and peripapillary choroidal thicknesses were measured before surgery and on the postoperative first day (D1), first week (W1), first month (M1), second month (M2), and third month (M3). Subfoveal choroidal thickness measurement included total subfoveal choroidal thickness (tSFCT), the small choroidal vessel layer (SF-SCVL) thickness, and the large choroidal vessel layer (SF-LCVL) thickness.
The greatest increase in mean tSFCT compared to baseline was observed between W1 and M1 with values of 23.33 ± 2.96 µm and 31.84 ± 2.88 µm, respectively, for the PXS and non-PXS groups (P = 0.014). The greatest increase in SF-SCVL thickness compared with baseline occurred at M1 with values of 6.66 ± 1.97 µm and 26.52 ± 1.92 µm, respectively, for the PXS and non-PXS groups (P < 0.001). The peripapillary choroidal thickness only showed a significant difference between the groups at the inferior measurement point with values of 117.94 ± 14.15 µm and 137.52 ± 34.53 µm, respectively, for the PXS and non-PXS groups (P = 0.032).
Cataract cases with PXS exhibited a different choroidal thickness response compared to non-PXS eyes after successful phacoemulsification. The increased choroidal thickness was particularly observed in Haller's layer in the eyes with PXS and in the choriocapillaris and Sattler's layer in the eyes without PXS.
