Trial Outcomes & Findings for How Has Glaucoma Affected Your Quality of Life? (NCT NCT01476644)

NCT ID: NCT01476644

Last Updated: 2019-11-15

Results Overview

National Eye Institute Visual Function-25 questionnaire (NEI VFQ-25) is a measurement of patients perception of their visually related quality of life. Patients select answers from multiple choice lists of responses. Values are re-coded and converted to a scale of 0 to 100 where 0 is extreme difficulty and 100 is no difficulty at all (or best quality of life). Data from visits 2 through 5.

Participant Flow

Moderate glaucoma subjects recruited from the Glaucoma Service at Wills Eye Hospital, Philadelphia, Pennsylvania between May 2012 and May 2014 for an observational longitudinal study. One baseline and four annual visits were performed.

Participant milestones

Measure
Participants With Moderate Glaucoma
Participants with moderate glaucoma as defined by a disc damage likelihood scale (DDLS range 1 to 9) of the optic nerve between 5 and 8 in at least one eye. One on the DDLS corresponds to healthy optic nerve; 9 is advanced glaucoma damage.

SECONDARY outcome

Timeframe: 2 hours at each annual visit, visits 2 through 5

Modified Glaucoma Symptom Scale (MGSS), is patient perception of their eyes comfort. Ten ocular complaints often associated with glaucoma each have a four level score (1 signifying very bothersome; 4 represents absence of problems). Scores from 10 questions are added and range from 0 to 100 where 0 represents significant discomfort and 100 represents no problems at all. The final MGSS score is an unweighted average of responses to 10 items, averaged between the 2 eyes. Data from visits 2 through 5.
