Background: Aim is to identify whether tigroid fundus modifies the incidence of retinopathy in diabetic patients and to assess whether it is a protective factor for diabetic retinopathy. Methods: This was a hospital based descriptive study.100 each of tigroid and non tigroid who were 41years and above having diabetes ≥5years were included. All cases except those who had myopia >-0.5D were included. Visual acuity was recorded. Anterior and posterior segments were examined. Diabetes was labelled controlled if HbA1c was <6.5% and uncontrolled if >6.5%.Results: Among 100 patients of each group, 72% with tigroid fundus and 13% with non tigroid fundus had no DR. Among 115 patients of >10 years duration DR was high in non tigroid (38% tigroid and 98% non tigroid) when compared to those with duration <=10 years (15.5%tigroid and 70% non tigroid). Also patients with duration <=10 years,84% tigroid fundus and 30% non tigroid fundus had no DR when compared to >10 years duration which were 61%tigroid fundus and 2% non tigroid fundus. Among patients with HbA1C<=6.5%, 86% tigroid and 25% non tigroid has no DR. Also DR was more in non tigroid (74%) than in tigroid (13%).In patients with HbA1C>6.5%,65% tigroid and 2%nontigroid has no DR. DR was more in non tigroid (98%) than in tigroid (34%).In each age group tigroid fundus has less DR compared to non tigroid fundus. Conclusion: Tigroid fundus was observed as a protective factor for DR and association of age, Hb A1c and duration of diabetes for development of DR in both tigroid and non tigroid fundus was significant(p value <0.001).
