Clinical Investigation What Do Patients With Glaucoma See? Visual Symptoms Reported by Patients With Glaucoma

Loss of visual acuity in glaucoma has traditionally been described as a loss of "peripheral vision". This prospective study aims to improve clinical understanding of visual symptoms caused by glaucoma.

Patients with various types and stage of glaucoma clinically diagnosed are included. Everyone including octopus vision test received comprehensive visual acuity test. If a patient has other eye diseases affecting vision, including cornea, lens, or retinopathy, that patient is excluded. The patient answered an oral questionnaire about his visual symptoms. We examined the visual symptoms described in glaucoma patients and correlated the reported visual symptoms with the severity of visual loss.

99 patients completed the questionnaire. Most patients (76%) were diagnosed as primary open angle glaucoma. The most common symptoms reported by all patients, including early or moderate glaucoma patients, require brighter and blurred vision. Patients with a large visual field loss (tachometer mean defect> + 4 dB) see as if seen through dirty eyeglasses, and as if it is difficult to distinguish boundary from color, on one or both sides It is likely to report difficult objects

Loss of visual acuity in glaucoma patients is not as simple as conventional peripheral vision loss. More brightness and blurred vision is the most common symptom reported by glaucoma patients

These lateral vision disorders become more pronounced only at the mid-stage of the disease, but some patients will never notice the symptoms. If one eye is more prone to glaucoma than the other, most of the visual activity involves the use of both eyes, so a more healthy eye compensates. In addition, central vision is affected only in later stages of glaucoma, so many progressive glaucoma patients still have 20/20 eyesight in the center. Because of this symptom, it is estimated that 50% of 3 million Americans suffering from glaucoma do not know that it is suffering from glaucoma.

Clinical investigation What did glaucoma patients see? Visual symptoms reported by glaucoma patients

99 patients completed the questionnaire. Most patients (76%) were diagnosed as primary open angle glaucoma. The most common symptoms reported by all patients, including early or moderate glaucoma patients, require brighter and blurred vision. Patients with large visual field loss (Octopus mean defect> 9.4 dB or more) report objects that are difficult to see on one or both sides, as seen through dirty eyeglasses, and difficult to distinguish between boundaries and colors The possibility is higher.
