Why Patients With Glaucoma Lose Vision: The Patient Perspective.

ABSTRACT: PURPOSE:To explore why glaucoma patients believe that glaucoma continues to cause vision loss despite the availability of effective treatment. METHODS:Nine focus groups were conducted in 3 geographically and ethnically diverse areas of the United States (Los Angeles, CA; Rochester, MN; Durham, NC) that included 56 participants, 31 with poor vision and 25 with good vision. Content analysis was used to identify important themes. Semiquantitative analysis was used to measure the frequency of each theme. RESULTS:A total of 474 relevant comments were made in the 9 focus groups. Focus groups elicited 305 comments about barriers to glaucoma management including issues with adherence (30%), the doctor-patient relationship (21%), knowledge about glaucoma (19%), personal support systems (19%), and barriers to health care delivery such as cost and insurance (11%). A total of 101 comments were made regarding feelings about glaucoma and 58 comments were made regarding beliefs about disease and treatment. CONCLUSIONS:These focus groups brought up many issues surrounding barriers to glaucoma treatment, perceived susceptibility to glaucoma, perceived benefits to treatment, and the emotional response to living with glaucoma. There is a need to create a more comprehensive chronic disease management approach for patients with glaucoma to address both the concrete and emotional issues identified in these focus group discussions.

Project description:Vision is the most powerful sense guiding our interaction with the environment. Its process starts with the retinal image as input and results in visually guided behaviors as output. This paper summarizes insights I gained over >40 years dealing with clinical ophthalmology, visual science, and vision rehabilitation, disciplines that all involve vision, but from different points of view. The retinal image contains 2-dimensional forms that have no inherent meaning. The brain matches this input to stored concepts, to create a Mental Model that is filled with 3-dimensional objects that are meaningful and linked to other senses. Ultimately this leads to the output of goal-directed visually guided behavior. The processes involved are too complex to be covered by a single practitioner. Optimal vision rehabilitation requires teamwork that includes contributions from various professions. It also requires an understanding, as well as possible, of the cerebral processes involved. The visual sciences study mostly the input-driven process from retinal image to visual percepts. Their studies deal mostly with groups and group averages and only occasionally with individual disease conditions. Clinical ophthalmology deals mostly with individuals, rather than group averages. The motto of the American Academy of Ophthalmology reminds us that the end point of patient care goes beyond "preserving sight." It also includes "empowering lives" by creating the conditions for goal-directed interaction with the environment through visually directed behavior. Traditionally, the study of vision has mainly involved the conscious part of vision, handled mostly in the ventral stream. However, the subconscious part of vision, handled mostly in the dorsal stream must also be considered. This is further stimulated by the demands of computer vision, image processing, and artificial intelligence. Vision rehabilitation traditionally deals with the input side through better illumination and various magnification devices. This is the domain of low vision aids. Increasingly, however, it must also address the output side, and the involvement of other senses (braille, long cane, and talking books). This requires better understanding of the goal-directed higher visual processes. The supplemental material covers the development of numerical scales to quantify not only visual acuity but also visual abilities, and the use of different tests.Financial disclosuresThe author(s) have no proprietary or commercial interest in any materials discussed in this article.
