Purpose : To assess the relationship between the leak location and neurosensory detachment (NSD) on retro-mode scanning laser ophthalmoscopy (RM-SLO) in clinically diagnosed cases of central serous chorioretinopathy (CSCR)
Methods : RM-SLO (Nidek,Fremont,CA) images of CSCR cases were analyzed on ImageJ (NIH, Bethesda,USA). The angiographic leak location was predetermined and co-localised on the RM-SLO. NSD parameters including maximum vertical and horizontal diameters (Vmax and H max), area and circularity index were measured. Leak location parameters including two-dimensional location of leak from intersection of Vmax and Hmax, quadrant and hemispherical location of leak with respect to fovea were measured.
Results : RM-SLO images of fifty two eyes with CSCR were evaluated which included forty six males and six females. The mean age was 42.15± 8.41 years while the mean logMAR best corrected visual acuity was 0.127(Snellen’s equivalent 20/26).A positive correlation was noted between two dimensional location of the leak and the area (rs =0.52,p=0.0001), vertical (rs =0.49,p=0.0002) & horizontal(rs =0.53,p=0.0001) diameters of NSD. The area of NSD showed a statistically significant (p<0.0001) difference with respect to the hemispherical location of leak with superior more than inferior. The difference in mean Hmax for different leak locations was statistically significant (p=0.01) with the highest mean noted with superotemporal leak.
Conclusion : The two dimensional leak location is a reliable determinant of area, vertical and horizontal extent of NSD. Superior leaks present with larger areas of NSD while superotemporal leaks result in wider NSD. RM-SLO can be used to reliably correlate the leak location and NSD in cases of CSCR.
