Comparing Reading Speeds for Reading Standardized Single Sentences and Paragraphs in Patients with Maculopathy

Area of Science:

• Ophthalmology
• Visual Sciences
• Clinical Research

Background:

• Maculopathy significantly impacts visual function, affecting reading speed (RS).
• Standardized text types are crucial for reliable RS assessment in clinical studies.
• Choosing appropriate text length is key for accurate repeatability measurements.

Purpose of the Study:

• To compare the repeatability of reading speeds (RS) using single sentences versus paragraphs in maculopathy patients.
• To determine the optimal text type for RS measurements in studies involving maculopathy.

Main Methods:

• Reading speed was measured in 25 maculopathy patients using standardized German sentences and paragraphs.
• Texts were presented via a closed-circuit TV system with size adjusted to individual magnification needs.
• Bland-Altman analysis was used to assess differences and repeatability of RS based on text length.

Main Results:

• No significant difference in mean RS was found between sentences and paragraphs.
• Paragraphs demonstrated lower variability and higher inter-chart reliability (12.9 wpm) compared to single sentences (36.4 wpm).
• RS correlations were highest between paragraph samples (r=0.98) versus sentence samples (r=0.81-0.90).

Conclusions:

• Single sentences are suitable for single RS measurements in maculopathy.
• Paragraphs are preferable for repeated RS measurements due to lower variability, aiding in monitoring reading disorders or intervention outcomes.
