Assessment of contrast sensitivity in children aged 3 years 9 months – 6 years with normal vision, visual impairment due to ocular disease and strabismic amblyopia

In music listening, limitations on visual experience affect a listener’s abstract information processing and conceptualization of the music. The aim of this study is to examine the differences in emotional responses to music between adults with visual impairment (VI) and adults with normal vision (NV). By using specific, emotion-inducing music reflecting happiness, sadness, anger, and fear, this study considers factors such as music emotion identification, emotional valence, arousal, intensity, and musical preference. A total of 120 participants (60 VI and 60 NV) listened to sixteen 15-second music excerpts and reported which emotion and to what extent they perceived it, using a self-reported music emotion evaluation scale. The results indicated that both of the groups showed high congruence in music emotion identification. However, the VI group showed significantly higher arousal, intensity and preference for sadness, while showing the lowest score for the intensity of fear. The main factor affecting emotion identification was preference for the VI group, and valence for the NV group.

<p class="0abstract">The issue of lacking reference books in braille in most public building is crucial, especially public places like libraries, museum and others. The visual impairment or blind people is not getting the information like we normal vision do. Therefore, a multi languages reading device for visually impaired is built and designed to overcome the limitation of reference books in public places. Some research regarding current product available is done to develop a better reading device. This reading device is an improvement from previous project which only focuses on single language which is not suitable for public places. This reading device will take a picture of the book using 5MP Pi camera, Google Vision API will extract the text, and Google Translation API will detect the language and translated to desired language based on push buttons input by user. Google Text-to-Speech will convert the text to speech and the device will read out aloud in through audio output like speaker or headphones. A few testings have been made to test the functionality and accuracy of the reading device. The testings are functionality, performance test and usability test. The reading device passed most of the testing and get a score of 91.7/100 which is an excellent (A) rating<strong>.</strong></p>

Objective: The objective of our study was to assess the variations in contrast sensitivity values of normoglycemic subjects and that of type II diabetic subjects of the same age group. It was also aimed at finding the visual acuities and study the associations of it with contrast sensitivity if any. Methods: It was a hospital-based comparative cross-sectional descriptive study conducted in the out-patient department of the Department of Ophthalmology, Saveetha Medical College, Hospital, Chennai. Visual Acuity and Contrast Sensitivity of 50 Type II Diabetic individuals and 50 age-equivalent control group subjects were measured using the Snellen’s chart and Pelli-Robson chart, respectively, during the months of January to March 2020. Results: Contrast Sensitivity measurements from 50 subjects with Non-Insulin dependent Diabetes Mellitus (NIDDM) were obtained. The subjects were the ones who had minimal or no diabetic retinopathy. It was observed that there is a significant association between reduced contrast sensitivity and Diabetes (P value<.00008). We also noted that CS may be reduced without corresponding loss of Visual Acuity. Hence, both visual acuity and contrast sensitivity measurements are helpful in the assessment of visual impairment due to diabetic eye disease. Conclusion: The contrast sensitivity can be seen as an early marker for visual impairment in diabetic eye care.
