Abstract Details



Purpose:

To assess the efficacy of navigated laser treatment in treatment for central serous chorioretinopathy (CSCR).

Setting:

Tertiary Eye Care Center

Methods:

Prospective study included 16 eyes of 15 subjects with non-resolving CSCR. All subjects underwent fluorescein angiography (FA) and navigated laser photocoagulation. Pre-treatment best corrected visual acuity (BCVA), central macular thickness (CMT), number of leaks on FA, treatment parameters including total number of shots for each leaking spot, average power used, post-treatment BCVA and CMT were noted. Patient’s pain experience was evaluated using the Visual Analog Pain Scale (VAS).

Results:

Total 16 eyes of 15 subjects (12 males and three females) were enrolled with mean age of 42.2 ± 9.9 years. Mean duration of symptoms was 11.45 ±16.6 months. Mean pre-treatment BCVA and post-treatment BCVA at 2 months was 0.28 (approximately 20/40) and 0.17 (approximately 20/30) logMAR respectively (p=0.171). Average number of leaks per eye was 2.8 and one laser spot photocoagulation per leak was performed. Average spot size was 94±9.48 microns. Mean power used for each laser spot was 106.1±32.0 mW. Mean CMT was 337.1±231.5 and 165±61.8 microns at baseline and at two months follow up (p=0.007). Complete resolution of subretinal fluid at 2 months of follow up was noted in 15 out of 16 eyes. Average VAS score was 0.63±1.41.

Conclusions:

Navigated laser treatment without contact lens achieved resolution of subretinal fluid with single laser spot for a single leak with minimum power. Laser planning and treatment on the computer screen, makes navigated laser a preferred option for extrafoveal leaks in CSCR.
