The study, from Edinburgh and Dundee universities, found that diabetes sufferers of South Asian descent - those from India, Bangladesh and Pakistan - were more likely to experience eye complications and higher blood sugar levels despite receiving the same level of care.
Researchers looked into the care given to patients with type 2 diabetes by sifting through a database of all diabetes patients in Tayside.
They found that South Asians were subject to the same or an even higher standard of medical care than other Scots.
Dr Colin Fischbacher, from the University of Edinburgh's school of clinical sciences and community health, said: 'This study shows that South Asians are more likely to get diabetes and that when they do develop the condition they suffer more complications.
'It is very encouraging to know that they receive the same high standard of medical care but we need to ensure that more is done to control their diabetes and to prevent the potentially devastating complications that can result from it.'
