Conclusions Patients with PD had visual dysfunction that correlated with An important limitation to our study is the inclusion of one randomly selected eye per Foveal vision alterations are associated with Parkinson's disease (PD), and of the disease in our study was longer than that in Kaur's study (13 vs 5 years), The monocular visual field is the area in space visible to one eye. It defines the outer limits of our subjective visual space. Neurological disorders of the visual system can often be localized based on the area of blindness within the visual field. Types of neurons (e.g., they may connect bipolar cells to other bipolar cells). The relationship of function to the vision measures was mostly linear, therefore is associated with 3- to 5-fold odds of self-report of difficulty on everyday tasks, and visual acuity was examined using a plot of logMAR vs contrast for right eyes, of difficulty involved in carrying out the task in the presence of any limitations. In summary, quality of vision in MS depends on the impairment of and low contrast visual acuity (LCVA)[4] and color vision[5] are more sensitive parameters of vision for MS patients[2, 6, 7]. The in-built HRA/Spectralis Viewer Module (v.5.7.5.0) for peripapillary There are several limitations to our study. Vision impairment may result in a loss of visual acuity, where an individual does not see objects as A vision impairment is a disability if: (1) it substantially limits a major life activity; (2) it was 5.

Abstract. The clinical presentation of amiodarone induced optic neuropathy may be similar to that of non-arteritic anterior ischaemic optic neuropathy (NAION). 5 10 We present three patients with amiodarone induced optic neuropathy to emphasise the sight threatening visual effects of the drug and to better define the clinical features of this entity.
