Abstract Details

Purpose:

The cystoid macular edema is a noteworthy complication after YAG capsulotomy. In previous studies cystoid macular edema has been linked with laser energy. We aimed to take attention to the importance of anterior hyaloid damage (AHD) and discuss it based on literature.

Setting:

Muğla University, Training and Research Hospital,Mugla, Turkey

Methods:

In our prospective, cross-sectional study, 277 pseudophakic eyes of 216 patients were enrolled. Pulse number, pulse energy, and total energy were noted. Anterior hyaloid faces were assessed during procedure and 1 day after the procedure. Eyes with and without AHD were compared according to Nd:YAG laser parameters. Retinal complications were evaluated at day 1, week 1, month 1, and month 3.

Results:

Anterior hyaloid damage was observed in 49 eyes (19.2 % of 255 eyes). The pulse number, pulse energy, and total energy were observed to be higher in eyes with AHD (P < .001, P = .024, P < .001, respectively). Cystoid macular edema was detected in five eyes (three with AHD) at 1-week examination. Occurrence of retinal complication in the AHD(+) group was 12.7 times higher than in the AHD(-) group, adjusted for total energy used (P < 0.001).

Conclusions:

Not only laser energy but also anterior hyaloid damage should be considered for YAG laser-related retinal complications. The risk of AHD may increase with high pulse number, pulse energy, and total energy.
