Preservation of the Photoreceptor Layer Following Subthreshold Laser Treatment for Diabetic Macular Edema as Demonstrated by SD-OCT

Abstract

In this study, subthreshold laser treatment for DME has been shown to be a safe technology that preserves the photoreceptor layer, as demonstrated by SD-OCT.

Comparison of Intravitreal Aflibercept and Ranibizumab following Initial Treatment with Ranibizumab in Persistent Diabetic Macular Edema

“…If ≥50% of the central foveal 1 mm zone was affected by DRIL, then DRIL was considered as present according to a previous study [ 14 ]. If EZ was disrupted within the 1 mm foveal area, EZ was graded as not intact [ 15 ]. B scans were evaluated by two independent specialists (Ali Demircan and Zeynep Alkin).…”

“…The greatest advantage of the MAIA is the ease of the operation since it does not require mydriasis; the much lower cost compared to other instruments is an added advantage. It utilizes the Scanning Laser Ophthalmoscope (SLO) technology to image the retina with higher resolution (of 1024 x 1024 pixels) and a more effective eye tracker to monitor the eye movement at 25 times per second improving reliability and usability for operators and patients [18][19][20][21][22][23][24][25][26][27][28][29][30][31]. In addition, the MAIA is the only instrument that offers automatic estimates on PRL characteristics during early and late fixation [31].…”
