Efficacy of optical coherence tomography and fundus fluorescein angiography in detection of diabetic macular edema
Journal Title: Indian Journal of Clinical and Experimental Ophthalmology - Year 2018, Vol 4, Issue 2
Abstract
Purpose Significance of clinical DME in an up becoming capital nation of diabetes mellitus in world has socioeconomic effect due to VTDR is identified as the major cause of irreversible blindness in DR subjects in all age groups Therefore the need for reliable safe and immediate detection of DME is a need for prevention of the disease related socio economic burden The study was to compare the diagnostic potential of two commonly established diagnostic instruments ieSDOCT FFA for the detection of DMEMaterials and Methods A prospective study with purposively sampling technique was carried on 308 eyes of 154 type II DM patients to compare the detection potential between two popular retinal diagnostic techniques SDOCT a noninvasive technique versus FFA invasive method for DME The standard parameters such as focal macular edema diffuse macular edema and mixed edema with cystoid type were evaluated with FFA Subsequently DME classification with presence of intraretinal edema sub retinal fluid and mixed edema were diagnosed with SDOCT for the same pool of patients Clinical features in DME using reference EDTRS scale of measurementResults Noninvasively 305 991 eyes were detected positive for various type of DME by SDOCT while 282 916 eyes were detected positive by FFA The prevalence of different types of DME such as cystoids diffuse focal and mixed was 78 13 71 and 637 respectively as diagnosed with FFA Whereas SRF IR edema and mixed type was 49 36 and 906 respectively as diagnosed with SDOCT DME was not detected by FFA in 84 of eyes in overall study population Whereas SDOCT was unable to detect DME in 09 of eyes In our study overall performance of SDOCT was better in detection of DME when compared to FFAConclusion The present study showed the diagnostic potential and efficacy of SDOCT over FFA in reliable and safe detection of DME in Type II Diabetic Mellitus patients was more and was easy and comparable to diagnostic findings of FFA specifically in cases of sub retinal macular as well choroidal edema due DME by SDOCTKeywords Diabetic macular edema Fundus fluorescein angiography Optical coherence topography
