Our study aimed to improve our understanding of how glaucoma affects vision from the patients' point of view by asking specific detailed questions about how they see. Although quality of life measures address physical symptoms, 16, 17 there are no tools to consider visual symptoms in detail. Currently, there are no objective methods to assess what patients experience subjectively. The goal of this prospective study was to assess the visual symptoms described by patients with glaucoma. (C) Loss of peripheral vision for the person implies loss of sight off to the person's sides, either the right and left side (as shown) or above and below. Loss of peripheral vision for the left eye means loss of vision toward the edges of the VF of that eye. (A) Loss of “peripheral vision” can use an eye or a person as its central reference point. 10– 12 Additionally, patients may report other visual symptoms due to glaucoma, such as blurriness, dimness or cloudiness. ![]() 9– 13 Several studies have demonstrated that in addition to VF losses, deterioration of contrast sensitivity and color discrimination can occur early in the disease process. 8 However, glaucomatous vision loss may involve not only narrowing of the visual field (VF) but also deterioration in the quality of vision. 4– 7 Current educational Web sites for the general public illustrate the loss of vision in glaucoma as “tunnel vision” or as if one is “looking through a straw” (Figure (Figure1 1). ![]() Vision loss due to glaucoma has traditionally been described as loss of “peripheral vision” that is, loss of vision at the outer edges. population continues to age, the prevalence of glaucoma is projected to reach 3 million by the year 2020. Glaucoma is one of the leading causes of blindness worldwide with a prevalence of over 2 million in those aged 40 years and older in the United States.
