Abstract

Background: Advances in laser technology have led to the development of selective treatment without chorio-retinal damage. Subthreshold micropulse yellow laser has widespread benefits for the treatment of different macular disorders, as it allows the treatment of central macular edema without damage of photoreceptors or ganglion cell complex. Methods: Two hundred eyes of 120 patients with center involved mild to moderate macular edema attending at vitro-retinal unit/ ophthalmology department at Sohag Teaching Hospital were included. A pre-subliminal laser assessment of BCVA, CMT, and GCC was performed. Follow-up assessments were performed at one month, three months and six months post-laser treatment. Results: Comparing pre- and post-yellow (577nm) subliminal laser assessment results revealed statistically significant increases in mean BCVA and statistically significant decreases in CMT at one month, three months and six months post-yellow (577nm) subliminal laser treatment. Statistically significant increases at one-month post-laser were found in superior, inferior and average GCC, followed by a decrease in their mean counts at three months as well as at six months post-laser (that was statistically significant for inferior GCC). Conclusion: yellow (577nm) sub-liminal laser therapy can be considered as an effective and safe management of centrally involved macular edema as it significantly improves BCVA and CMT with negligible decrease in GCC.
