Abstract

Purpose:

To evaluate the vision related quality of life in patients with Dry eye syndrome using the National eye institute Visual function Questionnaire (NEI VFQ-25)

Methods:

Data from patients with Dry eye syndrome, Uveitisretrieved from NEI database

Visual function questionnaire used to assess the impact of the disease process on the quality of life data

Results:

  • Dry eyes (n=22), were compared with Uveitis (n=48) and reference control (n=22) were identified.
  • Mean subscale scores were lower in patients with dry eyes and uveitisas compared with controls
  • Subscale analysis showed that mean responses were lower in terms of general health, general vision, near vision, distance vision, driving, peripheral vision and social functioning as compared to controls.
  • Distance vision and driving were the most significantly affected in dry eye patients compared to controls.

Conclusion:

  • Patients with dry eye syndrome have poorer vision related quality of life.
  • Apart from the severity of the disease symptoms, assessing quality of life helps in understanding the impact of the disease process and the treatment effect.
background
Background
  • Ocular surface disorders can result in impairment of vision related quality of life
  • Apart from Visual acuity, other aspects of visual function can result in vision related disability
  • NEI VFQ-25 questionnaire is an instrument designed to evaluated the vision related quality of life and to test psychometric properties of diseases that cause vision loss
purpose
Purpose
  • To evaluate the vision related quality of life in patients with Dry eye syndrome using the National eye institute Visual function Questionnaire (NEI VFQ-25) and to compare with normal and disease controls
materials and methods
Materials and Methods
  • Visual function questionnaire were retrieved from patients with dry eye syndrome and uveitis from a database at NEI.
  • NEI VFQ-25 addresses 12 subscales: General health, Near vision, Distnace vision, Driving, Peripheral vision, Color vision, Ocular pain, Role limitation, Dependency, Social functioning, Mental health
materials and methods1
Materials and Methods
  • Scores of VFQ-25 were converted to scaled scores as per scoring algorithm
  • Subscale scores were also compared with previously published reference controls.
results
Results
  • Mean subscale scores:
    • lower in patients with dry eye syndrome and uveitisas compared with published reference controls.
    • No differences between dry eye syndrome and uveitis patients
  • In patients with both dry eye syndrome and uveitis,
    • mean responses were significantly lower in terms of general vision, near vision, distance vision, driving, peripheral vision, role difficulty, dependency, mental health and social functioning as compared to controls (p <0.05).
  • Distance vision and driving were the most significantly affected in dry eye patients compared to controls.
discussion
Discussion
  • Patients with Dry eye syndrome experience subjective negative impact in vision related quality of life.
  • Compared with reference controls the subjective impact was significant in most of the categories except color vision and peripheral vision
  • Compared to other vision threatening diseases like uveitis, it had similar impact in vision related quality of life
conclusions
Conclusions
  • Patients with dry eye syndrome have significantly lower vision related quality of life comparable to sight threatening diseases like uveitis.
  • Assessing vision releated quality of life can determine the impact of disease process and treatment effects
