Materials and Methods: A Prospective, comparative case control study. The study included 120 eyes w with type I diabetes recruited from the outpatient clinic. All patients examined ophthalmologicaly and tested with Nassar Colour plate test, FFA and OCT. The Main Outcome Measures is The presence of mild or moderate tritans indicate early DME changes were documented in each group. Student's t-test and ANOVA (f) test were used for statistical analysis. P values less than 0.05 were considered statistically significant.
Results: The 120 patients seen were with type I diabetes. The mean age of the patients was 41.15±5.61 years (range 23-49 years) with a mean disease duration of 13.56±2.59 years (range 10-20 years). All patient with dry macula (n=60.50%) were normal while with DME showed normal (n=6.5%) , mild tritan (n=14, 11.66%) and moderate (n=40, 33.33%) the nassar color test is 90% Sensitive and 100% Specific
Conclusions: The Nassar color plate is a cheap and effective test to early detect macular edema and recommend to be used in all ophthalmic primary examination especially in areas far away from OCT and FFA
