Retinopathy in Maltese type 2 diabetic patients.
Since diabetes is a major health problem in Malta a study was conducted to gain a better insight into one of its most common complications, that of retinopathy. A random sample of 200 cases of adult onset diabetes with retinopathy who attended the main hospital's diabetes clinic was assessed by an experienced ophthalmologist. Non-proliferative retinopathy was subdivided into three degrees of severity according to the number of microaneurysms, haemorrhages, exudates, and intraretinal microvascular abnormalities present while proliferative retinopathy included also advanced eye disease. Data on medical and family histories was gathered from personal interrogation and counterchecked from hospital files. A medical examination searched for other concomitant disease. The 124 females and 73 males were similarly aged with a mean of 59.5 +/- 11.5 years. The mean age at onset of diabetes was 44.4 +/- 7.9 years: no significant differences were seen between the grades of retinopathy or the sexes. Onset of eye disease was first detected at a mean age of 56.9 +/- 7.0 years. The great majority (82%) of retinopathy cases occurred after 10 years of diabetes. Males appeared to develop eye disease (especially non-proliferative) at a younger age (53.4 +/- 7.6 vs 58.9 +/- 6.6 years, p < 0.01) and after a shorter duration of diabetes (10.1 +/- 6.6 vs 14.0 +/- 7.8 years, p < 0.001) than females. Severity of retinopathy was strongly associated (p < 0.001), in females rather more than in males, with poor glycaemic control, use of insulin, presence of proteinuria and decreasing vision; and less markedly (p < 0.01) with duration of diabetes of more than 10 years, neuropathy and glaucoma.(ABSTRACT TRUNCATED AT 250 WORDS)
