Background: Parkinson's disease (PD) is one of the most common neurodegenerative movement disorders and its incidence is increasing worldwide along with population aging. Previous clinical and histologic studies suggest that the neurodegenerative process, which affects the brain, may also affect the retina of PD patients. Objective: The objective of this study was to determine the thickness changes of retina nerve fibers and macular volume with optical coherence tomography (OCT) in PD patients. Materials and Methods: The spectral domain OCT was used to assess the thickness of retinal nerve fiber layer (RNFL) and macular volume from 34 PD patients and 50 healthy age-matched controls. Results: Compared with healthy age-matched controls, the RNFL thickness of PD patients was much thinner (P < 0.05) in all retinal quadrants, with temporal thinning being more than nasal thinning. Macular volumes were diminished in both perifoveal and outer macular regions in all sectors (P < 0.05) with preserved foveal volume. The degree of tissue loss corroborated with the severity of disease as objectively assessed by standardized rating scales (UPDRS). Conclusion: There is generalized retinal nerve degeneration in patients of PD and the degree of loss correlated with the severity and duration of disease.

Background: The A 1 chieve, a multicentric (28 countries), 24-week, non-interventional study evaluated the safety and effectiveness of insulin detemir, biphasic insulin aspart and insulin aspart in people with T2DM (n = 66,726) in routine clinical care across four continents. Materials and Methods: Data was collected at baseline, at 12 weeks and at 24 weeks. This short communication presents the results for patients enrolled from North East, India. Results: A total of 730 patients were enrolled in the study. Four different insulin analogue regimens were used in the study. Patients had started on or were switched to biphasic insulin aspart (n = 518), insulin detemir (n = 88), insulin aspart (n = 74), basal insulin plus insulin aspart (n = 19) and other insulin combinations (n = 30). At baseline glycaemic control was poor for both insulin naïve (mean HbA 1 c: 9.5%) and insulin users (mean HbA 1 c: 9.2%) groups. After 24 weeks of treatment, both groups showed improvement in HbA 1 c (insulin naïve: −1.6%, insulin users: −1.5%). SADRs including major hypoglycaemic events or episodes did not occur in any of the study patients. Conclusion: Starting or switching to insulin analogues was associated with improvement in glycaemic control with a low rate of hypoglycaemia.
