We evaluated the prevalence of DR in 295 type 2 diabetic patients admitted in our Department for DF from 2008 until 2011. All patients were examined with indirect and direct retinoscopy and two non-stereoscopic 45° retinal photographs for each eye. Of these 228 (77.3%) underwent to lower extremity transluminal angioplasty for critical limb ischaemia and PAD severity was graded according to Classification of Joint Vascular Society Council (JVSC).

Characteristics of the study

To determine the prevalence of diabetic retinopathy (DR) and to explore its correlation with severity of peripheral arterial disease (PAD) in Type 2 diabetic patients with diabetic foot (DF).

RETINOPATHY  PREVALENCE  

According to the table below it’s so possible to define: CALF SCORE: 1+ ü  Anterior tibial ü  Posterior tibial ü  Peroneal

FOOT SCORE: 1+ ü  Dorsalis pedis ü  Lateral plantar ü  Medial plantar

JVSC  SCORE  

For each patient who underwent to p e r c u t a n e o u s t r a n s l u m i n a l angioplasty we assessed the severity of peripheral arterial disease during the angiographic exam by the Classification score of Joint Vascular Society Council.

Thanks for attention

Conclusions

ü  We observed a high prevalence of DR in type 2 diabetic patients with foot complications (70% of these patients have some degree of DR).

ü  Furthermore, while no correlation was found between JVSC score and age, duration of diabetes or HbA1c respectively, in our patients the severity of diabetic retinopathy correlated with the severity of peripheral arterial disease (p<0.05 r=0,65).
