And no signs of proliferative  retinopathy





               Proliferative diabetic retinopathy     One or more of the following:
                                                             Neovascularization of the Disc or else where

                                                             Vitreous / preretinal hemorrhage


               International clinical diabetic retinopathy disease severity of diabetic macular edema
               2 Major levels, with subcategories for diabetic macular edema


               Proposed Classification              Findings Observable upon Dilated Ophthalmoscopy
               Diabetic Macular Edema Absent        No retinal thickening or hard exudates in posterior pole
               Diabetic Macular Edema Present       Some  retinal  thickening  or  hard  exudates  in  posterior
                                                    pole


               Diabetic macular edema is classified into three types based on FFA findings:
                            Focal exudative maculopathy

                            Diffuse exudative maculopathy
                            Ischaemic maculopathy.

               Term  clinically  significant  macular  edema(CSME)  is  considered  ,if  one  of  the  following
               criteria are present on :
                     Retinal  edema  or  Thickening  of  the  retina  at  or  within  500µ  of  the  centre  of  the
                       fovea.

                     Hard exudates at or within 500 µ of the centre of fovea associated with adjacent
                       retinal thickening
                     Retinal thickening of  size 1DD, at  least a part of which is within 1DD of the foveal
                       centre.


               Advanced diabetic eye disease.


                        Vitreous and preretinal haemorrhages occur as new vessels grow forward from
                         the retina and enter the vitreous where they bleed easily.
                        Haemorrhages  appear  as  reddish/dark  opacities;  preretinal  or  subhyaloid
                         haemorrhages.
                        Retinal detachment.
                        Rubeosis iridis .
