Clinical analysis of Clinically Significant Macular Edema (CSME) by Slitlamp Biomicroscopy with +90D lens, Optical Coherance Tomography (OCT) and Fundus Fluorescein Angiography (FFA) among patients of diabetes mellitus - cross sectional observational stud

Abstract

Introduction : Diabetic Retinopathy is a major cause of blindness in the world. Proper and affordable diagnosis of
Clinically Significant Macular Edema (CSME) is very much important for early detection and treatment of this kind
of vision loss. Slitlamp biomicroscopy with +90D lens (SLB), Optical Coherance Tomography (OCT) and Fundus
Fluorescence (FFA) are the available methods for detection of CSME. Clinical evalution of CSME by all these
methods is very much important to know their reliability, repeatability and affordability. Aim : To analyse findings of
slit lamp biomicroscopy with 90D lens, Optical Coherance Tomography and Fundus Fluorescein Angiography in
patient of diabetes with CSME. Methods : 33 eyes of 25 patients were analysed for findings of CSME by slitlamp
biomicroscopy with +90D lens, Optical Coherence Tomogrphy and Fundus Fluorescence Angiography after
general ophthalmic examination. Results : CME was found better on OCT (27%) in comparision to SLB (9%) and
FFA(18%). ERM (9%) and SRF(18%) was found only on OCT. Hard exudates were found better and equally on
OCT and biomicroscopy(85%) compared to FFA(18%). DRT was found by biomicroscopy(88%), OCT(100%),
FFA(85%). Conclusion : OCT helps in better anatomical characterization of CSME and therefore more relevant
while planning management strategies.
