Diabetic macular edema OCT

Purpose: More than ten years after ETDRS, Optical Coherence Tomography (OCT) greatly enhanced our ability to detect macular thickening and has brought new insights on the morphology of edema and on the presence of vitreal traction. In this study we propose a new classification of macular edema based on OCT findings to better catalogue and follow this complex clinical entity Optical coherence tomography (OCT) OCT shows three basic structural changes: retinal swelling, cystoid macular edema, and subretinal fluid. OCT is a more sensitive method for objective evaluation of vitreo-macular traction and for measurement of macular thickness. OCT can also be used to calculate the standardized change in macular thickness Diabetic macular edema with microaneurysm Figure 1: Diabetic macular edema with intraretinal edema secondary to leakage from the microaneurysm located in the center of the cyst. Figure 2: Diabetic macular edema with intraretinal fluid/cysts and subretinal retinal fluid. Leakage can occur from microaneurysms located in the intraretinal layers and spread.. Since the introduction of OCT several authors have studied the possibility of OCT for early diagnosis of macular edema, and have suggested criteria to detect the so called subc linical diabetic macular edema (Hee et al., 1995, 1998; Massin et al., 2002)

  1. Diabetic macular edema (DME) is one of the major causes of vision loss among patients with diabetic retinopathy. 1 Fluorescein angiography is an important diagnostic tool for the investigation of microaneurysms and leakage in the retina. However, the precise structure of deep retinal layers cannot be observed in fluorescein angiography
  2. OCT enables precise measurement of macular thickness. Thus, it facilitates detecting macular oedema which is the main pathologic feature of diabetic maculopathy. This is defined as any detectable retinal thickening due to fluid accumulation (ETDRS report number 10, 1991). The oedema may be symmetrical or involve only a sector of the macular area
  3. Introduction Diabetic macular edema (DME) is a late stage of diabetic eye disease that is characterized by retinal thickening in the macula, often accompanied by hard exudate deposition, and..
  4. RESULTS: The OCT images showed cystoid macular edema in 18 eyes and diffuse retinal swelling without cystoid edema in the other 27 eyes. The fovea was significantly thicker in eyes with cystoid macular edema and in those with diffuse retinal swelling than in normal eyes

Importance Diagnosing diabetic macular edema (DME) from monocular fundus photography vs optical coherence tomography (OCT) central subfield thickness (CST) can yield different prevalence rates for DME. Epidemiologic studies and telemedicine screening typically use monocular fundus photography, while treatment of DME uses OCT CST. Objective To compare DME prevalence from monocular fundus. In diabetic retinopathy (DR), macular involvement can present as either macular edema or ischemia. Fluorescein angiography remains the gold standard in the evaluation of retinal vascular perfusion and diagnosis of macular ischemia. However, it is a costly, time-consuming technique, it requires venipuncture, and reports of anaphylaxis and death related to fluorescein injections have been.
