Abstract Details



Purpose:

To evaluate changes in subfoveal choroidal thickness (SFCT) using spectral-domain optical coherence tomography (SD-OCT) in eyes with rhegmatogenous retinal detachment (RRD) which underwent pars plana vitrectomy (PPV).

Setting:

Nagoya University Hospital, Nagoya, Japan

Methods:

This retrospective study included 29 eyes of 29 patients who had PPV for th RRD. Best corrected visual acuity (BCVA), intraocular pressure (IOP), and SFCT were measured before and 1 week, 1 month, and 3 months after the surgery. The changes in measurements were compared between operated and fellow eyes.

Results:

The preoperative mean SFCT of eyes with RRD was 221.8 ± 58.9 µm and of fellow eyes was 201.6 ± 64.0 µm, respectively. The postoperative mean SFCT of operated eyes at 1 week, 1 month, and 3 months were 217.5 ± 63.8, 221.7 ± 54.1 and 209.9 ± 49.5 µm and of fellow eyes 208.1 ± 68.0, 208.1 ± 65.2 and 200.4 ± 49.5 µm, respectively. There was no significant change with time in the operated and the fellow eye. In addition, there was no significant difference between the operated eye and the fellow eye in all of observation time. A statistically significant increase in IOP (P<0.001) and an improvement in BCVA (P<0.001) were observed in eyes with RRD 3 months after the surgery. The increase of IOP was not significantly correlated with that of SFCT.

Conclusions:

There has been reported that the SFCT in eyes with RRD treated by buckling surgery increases temporally in early postoperative period. However, our result shows that the SFCT in eyes with RRD treated by PPV does not change after surgery. In addition, the postoperative increase of IOP does not affect the SFCT.
