Subthreshold micropulse green laser versus yellow laser in the treatment for chronic central serous chorioretinopathy
Purpose This study aimed to compare the functional and anatomical outcomes of the subthreshold micropulse yellow laser (SMYL) (577 nm wavelength) to the subthreshold micropulse green laser (SMGL) (532 nm wavelength) as a therapeutic option in the treatment of serous retinal detachment secondary to c...

| description | Purpose
This study aimed to compare the functional and anatomical outcomes of the subthreshold micropulse yellow laser (SMYL) (577 nm wavelength) to the subthreshold micropulse green laser (SMGL) (532 nm wavelength) as a therapeutic option in the treatment of serous retinal detachment secondary to chronic central serous chorioretinopathy (CSCR).
Patients and methods
This is a clinical interventional comparative prospective study that included 40 eyes of 40 patients with chronic CSCR for more than 3 months with neurosensory serous detachment. The eyes were equally randomized to either SMYL or SMGL (20 eyes in each group). The best-corrected visual acuity (BCVA) and retinal optical coherence tomography were assessed during the study’s 6-month follow-up period.
Results
There was no statistically significant difference in the baseline patient characteristics. There was a remarkable anatomical [80% had resolution of subretinal fluid (SRF)] and functional success (80% had improvement in BCVA) in the treated eyes. The maximal retinal height in the SRF-containing area improved significantly from 399±120 to 249±45 µm (P=0.000) and from 473±129 to 247±32 µm (P=0.000) at the final follow-up in the yellow and green laser groups, respectively, with no statistically significant difference between the two groups (P=0.061). The BCVA improved significantly from 0.37±0.19 to 0.74±0.33 (P=0.000) and from 0.48±0.32 to 0.83±0.19 (P=0.000) in the yellow and green laser groups, respectively, with no statistically significant difference between the two groups (P=0.824).
Conclusion
Both SMYL and SMGL modalities worked equivalently and achieved the same percentage of resolution of SRF and improvement of BCVA in chronic CSCR. |
