Visual Acuity Screening for early detection on Students Using Twin Cards Optotype

Myopia is seen as a benign condition which is a public health problem and must be given attention, concerning visual problems, quality of life, and economic consequences. Nearly half of the world's blindness has been caused by uncorrected refraction, with myopia occupying a high percentage of the group, meaning myopia is the beginning of blindness. Uncorrected disturbances of visual acuity should be screened This study aims to develop a method of screening for myopia in school children, resulting in twin card optotypes. The study was carried out by diagnostic tests to analyze the sensitivity and specificity of twin card optotypes in screening for visual impairment in schoolchildren using primary data from the visual test. The results of this study are twin card optotypes which can easily be used in almost any condition, without requiring access to electricity, not causing variables bullies in a row of questions on the same letter size. Faster time because it does not cause repeated questions one paper one object. Installation does not require encoding on the wall, avoid memorization and avoid factors from concerns about clinical validity and application accuracy. Conclusion Sensitivity of sharp vision screening method Optotip twin card when compared with snoten optotip vision sharpening method which is 83.33% while specificity is 71.43 %.

COMPARISON OF HANDWRITING LEGIBILITY FOR MANUAL HANDWRITING AMONG TYPICALLY DEVELOPING INDIAN CHILDREN

Handwriting involves the integration of many skills, including perceptual motor skills, motor planning and cognition visual motor skills, as well as control of kinesthetic and tactile abilities to grasp and maintain control of the writing tool, as well as motor control The aim of this study was to compare the handwriting skills of typically developing Indian children on ETCH-M (Evaluation Tool Of Children Handwriting – Manuscript). A sample of 200 typically developing Indian children were included in the study using convenience sampling method. The age ranged from 6 years to 9 years. It was found that ETCH-M is an assessment tool which can assess the Handwriting skills of Indian typically developing children in 6-9 years of age group. Independent sample t- test was done to compare the mean raw score of each group. There was a significant difference with statistical value of p< 0.001. The handwriting evaluation depends upon six characteristics of writing: Handwriting legibility, letter formation, uniformity of letter size, uniformity of letter slant, spacing between letters and words, alignment of lines of writing. KEYWORDS: Handwriting, legibility, occupational therapy, vernacular medium.

Functional Outcomes and Reading Speeds following PRESBYOND LBV Using Nonlinear Aspheric Ablation Profiles Combined with Micro-Monovision

Purpose. To report the functional outcomes and reading speeds following PRESBYOND laser blended vision (LBV) using nonlinear aspheric ablation profiles with micro-monovision with the Carl Zeiss Meditec MEL 90 platform. Methods. Data have been collected retrospectively for all patients who underwent PRESBYOND LBV using the MEL 90 excimer laser. Postoperative binocular uncorrected distance and near visual acuity, stereo-acuity, contrast sensitivity, and reading performance were compared with pre-op values measured with patient’s progressive glasses. Mean follow-up was 6 ± 1.2 months. Results. Sixty eyes of 30 patients (mean age 50.47 ± 6.43 years) were included. Of these, 18 patients were hyperopic and 12 patients were myopic with mean SE of 1.28 ± 1.38 D and −2.84 ± 1.86 D, respectively. At 6 months, the mean binocular UDVA was ≥−0.03 ± 0.06 log MAR and the mean binocular UNVA was ≥0.22 ± 0.04 log MAR. The uncorrected reading speeds (words per minute) at the preferred reading distance of 46.17 cm, 60 cm, and 80 cm were significantly better ( p value <0.01), whereas the smallest letter size and reading acuities were comparable to the preoperative values ( p > 0.05 for all distances). Uncorrected contrast sensitivity log values showed mild reduction; however, this was not statistically significant for any spatial frequency. There was a significant reduction in post uncorrected stereopsis to 89.67 arc sec, compared with pre-op corrected stereopsis (50.67 arc sec); however, it recovered fully with near correction (53.33 arc sec, p > 0.05 compared with pre). Conclusion. PRESBYOND LBV resulted in significantly better reading speeds and satisfactory functional visual outcomes, without a permanent change in stereo-acuity and contrast sensitivity 6 months postoperatively.

Parkinson’s Disease Diagnostics Based on the Analysis of Digital Sentence Writing Test

Analysis of the sentence writing test is conducted in this paper to support diagnostics of the Parkinsons disease. Drawing and writing tests digitization has become a trend where synergy of machine learning techniques on the one side and knowledge base of the neurology and psychiatry on the other side leading sophisticated result in computer aided diagnostics. Such rapid progress has a drawback. In many cases, decisions made by machine learning algorithm are difficult to explain in a language human practitioner familiar with. The method proposed in this paper employs unsupervised learning techniques to segment the sentence into the individual characters. Then, feature engineering process is applied to describe writing of each letter using a set of kinematic and pressure parameters. Following feature selection process applicability of different machine learning classifiers is evaluated. To guarantee that achieved results may be interpreted by human, two major guidelines are established. The first one is to keep dimensionality of the feature set low. The second one is clear physical meaning of the features describing the writing process. Features describing amount and smoothness of the motion observed during the writing alongside with letter size are considered. Resulting algorithm does not take into account any semantic information or language particularities and therefore may be easily adopted to any language based on Latin or Cyrillic alphabets.

Functional Results and Photic Phenomena with new Extended-Depth-of-Focus Intraocular Lens

Background: Evaluation of clinical and functional results of a new extended depth of focus intraocular lens (EDOF-IOL). Methods: Fourteen cataract patients (twenty-eight bilateral implantations) were assessed for uncorrected (UDVA) and corrected (CDVA) distance visual acuities; uncorrected (UNVA), distance-corrected (DCNVA) and best corrected (CNVA) near visual acuities; and uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuities - as well as binocular defocus curves. Photopic and mesopic contrast sensitivity was recorded. Reading acuity was evaluated using an electronic reading desk at fixed distances and at the patient’s preferred near and intermediate distances. Visual symptoms were assessed with a halo and glare simulator plus a patient questionnaire which also recorded quality of life. Results: Median postoperative monocular UDVA was 0.13logMAR (range -0.08 to 0.42logMAR), median CDVA was -0.01logMAR (range -0.20 to 0.22logMAR), median UIVA at 80 cm was -0.05logMAR (range -0.18 to 0.58logMAR) and median UNVA at 40 cm was 0.14logMAR (range -0.10 to 0.64logMAR). Binocular uncorrected reading acuity was 0.10logMAR at 40 cm and 0.11logMAR at 80 cm. Patients preferred a median intermediate reading distance of 62.8 cm over the predetermined 80 cm, which allowed them to read smaller letter size but did not improve reading acuity. Patients reported a high rate of spectacle independence and satisfaction in everyday life and little to no dysphotopsia. Conclusion: The Mini WELL Ready IOL provided good postoperative functional results at far and intermediate distances and improved the visual and reading acuity at reading distance. The lens caused little to no dysphotopsia.
