Impairment of Reading Ability in Dry Eye Patients

This study has been completed.

Collaborator:
Allergan
Information provided by (Responsible Party):
Esen K. Akpek, Johns Hopkins University
ClinicalTrials.gov Identifier:
NCT01826812
First received: April 4, 2013
Last updated: March 16, 2017
Last verified: March 2017
  Purpose
To assess the reading function impairment in patients with dry eye and to assess the effects of reading on the ocular surface.

Condition Intervention
Dry Eye Syndromes Other: 30 minutes sustained reading Other: Dry eye exam

Study Type: Observational
Study Design: Observational Model: Case-Control
Time Perspective: Prospective
Official Title: Functional Impairment of Reading Ability in Dry Eye Patients and Effects of Sustained Reading on the Ocular Surface

Further study details as provided by Esen K. Akpek, Johns Hopkins University:

Primary Outcome Measures:
  • Sustained Silent Reading Speed [ Time Frame: 30 minutes ]

Secondary Outcome Measures:
  • Change in Total Ocular Staining Score (OSS) [ Time Frame: Before and after 30 minutes reading ]
    Ocular staining score (OSS) is sum of the corneal and conjuctival staining scores with a total possible maximum score of 12 for each eye. Corneal staining is graded with a maximum possible fluorescein score of 6 for each cornea (the punctate epithelial erosions grade between 0-3 plus any extra points for modifiers up to 3). Nasal and temporal conjunctiva are graded separately with a score range between 0 and 3 for each area after instillation of lissamine green. An abnormal OSS is defined as being a total score of 3 or more.

  • Change in Tear Osmolarity [ Time Frame: Before and after 30 minutes reading ]
  • Change in Visual Acuity [ Time Frame: 30 minutes ]
  • Cytokines [ Time Frame: 30 minutes ]
    Identification of various inflammatory cytokines in tear film of dry eye patients comparing to controls and the effect of sustained reading to the levels of these cytokines.

Groups/Cohorts Assigned Interventions
Dry Eye
The patients with Sjogren Syndrome related or non-Sjogren Syndrome related dry eye. The participants will be asked some questions. Before and after reading a text silently in 30 minutes "30 minutes sustained reading", a detailed dry eye exam will be performed.
Other: 30 minutes sustained reading
The participants will be given a text to read silently in 30 minutes.
Other: Dry eye exam
Tear break-up time, tear collection, osmolarity, Schirmer test, corneal and conjunctival staining.
Controls
The patients without dry eye. The participants will be asked some questions. Before and after reading a text silently in 30 minutes "30 minutes sustained reading", a detailed dry eye exam will be performed.
Other: 30 minutes sustained reading
The participants will be given a text to read silently in 30 minutes.
Other: Dry eye exam
Tear break-up time, tear collection, osmolarity, Schirmer test, corneal and conjunctival staining.

Detailed Description:
This study is being done to understand how reading is affected in people with dry eye in comparison with healthy controls and what effect reading has on the ocular surface in patients with dry eye.
  Eligibility

Ages Eligible for Study:   50 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Patients with known dry eye as well as normal healthy control subjects with no ocular surface diseases will be recruited from the Ocular Surface Diseases and Dry Eye Clinic as well as Glaucoma Clinic of the Wilmer Eye Institute.
