Selective retina therapy (SRT) for macular serous retinal detachment associated with tilted disc syndrome.

PURPOSE: Tilted disc syndrome (TDS) may be associated with a macular serous retinal detachment (MSRD). However, ideal therapy for this complication is still unestablished yet to date. The purpose of this study is to investigate the effect of selective retina therapy (SRT) for MSRD associated with TDS.

METHODS

This retrospective study included 11 eyes of 10 patients (1 male and 9 females), who were treated with SRT for MSRD associated with TDS, and observed at least 12 months after treatment. The mean age was 56 years old (range 44-66). An SRT laser (527 nm, 1.7 μs, 100 Hz; Medical Laser Center Lübeck, Germany) was used for treatment. The changes of best-corrected visual acuity (BCVA), central macular thickness (CMT), and central choroidal thickness (CCT) were examined. Subfoveal curve height (SFCH) was calculated at baseline.

RESULTS

The mean follow-up period was 24.4 months (range 12-48 months). The mean BCVA (logMAR), CMT, and CCT changed from 0.03 ± 0.10, 324 ± 82 μm, and 194 ± 68 μm preoperatively to 0.07 ± 0.17, 274 ± 94 μm, and 188 ± 65 μm at final follow-up, respectively, with significant difference on CMT (BCVA: p = 0.44, CMT: p < 0.05, CCT: p = 0.21). The MSRD disappeared in 6 eyes (55%) and the average number of SRT irradiations until resolution of MSRD was 2.6 times (range 1-5 times). There was no significant association between SFCH and resolution of MSRD (p = 0.19).

CONCLUSIONS

SRT may promote absorption of MSRD and maintenance of BCVA for TDS. Randomized and prospective clinical studies are needed to evaluate the effectiveness of SRT for MSRD associated with TDS.
