Evaluation of morphology of cataracts in patients with NIDDM
Abstract
Purpose: Various population-based studies have shown the association between diabetes and cataracts and have defined various risk factors for the development of cataract. There is evidence that the risk of cataract increases with increasing duration of diabetes and severity of hyperglycaemia. This paper provides an overview of the morphology of cataracts among NIDDM patients of Himachal area of north India.
Material & Methods: This study was conducted in department of ophthalmology in MMMC & Hospital, Kumarhatti, Solan. 100 eyes of 62 patients in the age range of 50- 80 years with pre existing diabetes & cataract were recruited from Nov 17 to Oct 18 in prospective study. The morphology of cataract was categorised as per locs 3 protocol in which clinical assessment with slit lamp or grading performed on retro illumination photographs.
Results: Out of 100 eyes, 21 eyes with posterior subcapsular cataract, 16 eyes with cortical, 9 eyes with nuclear, 54 eyes with mixed component. Thirty-eight patients had bilateral cataract. After statistical analysis, it was seen that duration of diabetes & HbA1c levels are not significantly correlated with grades of cataract. However, the prevalence of 54% in case of mixed cataract in type 2 diabetes is high as compared to the monotype.
Conclusion: In this study it was found that duration of non-insulin dependent diabetes mellitus and HbA1C levels are not statistically correlated with the grades of cataract. Mixed cataracts were however more common than any particular morphology of cataract.
