Testing a Reading Module to Improve Reading Skills and Quality of Life in Glaucoma Patients
Evaluation of The Effectiveness Of Reading Rehabilitation Module On Reading Performance And Quality of Life In Patients With Glaucoma
The goal of this interventional study is to test the effectiveness of reading rehabilitation module towards reading speed and error, and quality of life in glaucoma patients.The main questions it aims to answer are:
- Is there a significant difference in reading speed over a 6-month period between glaucoma patients who undergo a reading rehabilitation module and those who receive standard care?
- To what extent does the implementation of a reading rehabilitation module reduce the frequency of reading errors in glaucoma patients compared to a control group across baseline, 3-month, and 6-month follow-ups?
- How does a structured reading rehabilitation module influence the self-reported quality of life in glaucoma patients from baseline to 6 months when compared to those receiving standard care?
Participants will:
Patients in interventional group will be instructed to practice the reading module for 20-30 minutes daily, minimum 3 days/week, for 6 months.
Visit the clinic once every 3 months for checkups and tests A logbook will be provided to record their practice sessions.
While participants in control group will receive standard care, visit the clinic once every 3 months for checkups and tests.

Descrição detalhada
Glaucoma is a leading cause of irreversible visual field loss, significantly impairing reading efficiency and vision-related quality of life. While conventional management focuses on intraocular pressure reduction to prevent disease progression, visual rehabilitation strategies targeting functional reading deficits remain limited in clinical practice. This randomized, single-blind, parallel-group control trial aims to evaluate the effectiveness of a structured, home-based reading rehabilitation module on reading performance and vision-related quality of life in patients with bilateral glaucoma.
Following ethical approval from the Human Research Ethics Committee of Universiti Sains Malaysia (JPeM), eligible patients attending the Ophthalmology Clinic at Hospital Universiti Sains Malaysia (HUSM) will be recruited and randomized into two arms: an intervention group receiving the reading rehabilitation module or a control group maintaining standard daily care (waitlist control). Randomization will be executed using sequentially numbered, opaque, sealed envelopes (SNOSE) to maintain allocation concealment.
Participants assigned to the intervention arm will receive standardized Malay-language narrative reading materials and will be instructed to practice the structured reading module at home for 20 to 30 minutes every 2-3days per week over a 6-month study period. Protocol adherence will be monitored using daily reading logs tracking session dates and durations, which will be audited during monthly follow-up visits. Participants maintaining less than 80% compliance will receive targeted counseling. Control group participants will receive standard clinical care and general visual health advice, with access to the rehabilitation materials offered upon completion of the 6-month trial.
Study assessments will be conducted at baseline, 3 months, and 6 months post-enrollment by an independent investigator blinded to group allocation. Reading performance metrics (reading speed in words per minute and error rate percentage) will be evaluated using the standardized Buari-Chen Malay Reading Chart at a 40 cm reading distance. Vision-related quality of life will be measured at baseline and 6 months using the validated, glaucoma-specific GLAUQOL-36 questionnaire (scored from 0 to 100, where higher scores reflect better quality of life). Data will be analyzed using repeated-measures ANOVA (RM-ANOVA) to evaluate time, group, and interaction effects across study visits.

Change in Reading speed
Prazo: Baseline, 3rd month and 6th month
|
Reading speed will be assessed using the Buari-Chen Malay Reading Chart at a 40 cm reading distance.
Participants read a standardized paragraph aloud.
Reading speed is calculated as: Reading Speed (wpm)= (Total words read correctly} / Total time in seconds) x 60.
|
Baseline, 3rd month and 6th month

|
Change in Reading error
Prazo: At baseline, 3rd month and 6th month
|
Reading errors (omissions, substitutions, mispronunciations, or skipped words) will be recorded using the Buari-Chen Malay Reading Chart.
The error rate is calculated as: Error Rate (%) = (Number of Errors / Total Words) x 100.
|
At baseline, 3rd month and 6th month
|
|
GlauQol-36 Questionnaire
Prazo: At baseline and 6th month
|
Vision-related quality of life will be evaluated using the Glaucoma Quality of Life 36-item Questionnaire (GLAUQOL-36).
The questionnaire covers 10 visual domains on a Likert scale.
Individual item responses are aggregated and converted to a total standardized score ranging from 0 to 100, where higher scores indicate a better vision-related quality of life.
