Validation of Romanian Version of Radner Reading Charts

Study Overview
=================
Brief Summary
-----------------
Interventional, parallel groups, single center trial with a prospective design

Detailed Description
-----------------
The Radner Reading Charts have been developed on the basis of the concept of sentence optotypes for the standardized examination of reading acuity and reading speed. Print sizes are logarithmically scaled (LogRAD) to permit statistical analysis, and the results obtained can be compared to other logarithmically scaled vision systems (e.g., LogMAR). To guarantee accurate, reproducible and standardized measurements of reading acuity and reading speed at every viewing distance, sentence optotypes have been created to minimize the variations between the test items and to keep the geometric proportions as constant as possible at all distances. Through interdisciplinary cooperation, a series of test sentences were developed that are highly comparable in terms of the number of words (14 words), as well as the word length, number of syllables, position of words, lexical difficulty and syntactical complexity. The most similar sentences were statistically selected for the Radner Reading Charts.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Radner test<br>reading speed evaluation | Diagnostic Test: Radner test<br>* The A5 reading booklet is held by the subject The subject is instructed to read sentence by sentence, by turning consecutively the pages of the booklet (on the first side is the number of sentence and the backward side contains the sentence) The subject is instructed to read the sentences aloud as quickly and accurately as possible to the end, and to not correct reading errors. One assessor is writing the reading time and records any reading errors on the scoring sheet while the second assessor is audio recording the operation Stop criterion: reading time longer than 20 seconds or severe errors.<br>* Other names: Validation of the Romanian version-Radner Reading Charts;|
