Abstract

OBJECTIVE:

To assess the quality of life in glaucoma patients and normal subjects, and to assess its relationship with the severity of damage in each eye.

METHODS:

A cross-sectional study was conducted with prospective selection of cases. The study included 464 subjects and were distributed into 4categories. Subjects included in group 1 had both eyes normal, that is with a normal intraocular pressure (IOP), optic disk and visual fields (VF), or mild glaucoma, defined as untreated IOP>21mmHg and abnormal VF with mean defect (MD) over -6dB. Group 2 consisted of patients with both eyes with mild or moderate glaucoma, defined as untreated IOP>21mmHg and abnormal VF with MD between -6 and -12dB. Group 3 included patients with moderate to severe glaucoma, that is, untreated IOP>21mmHg and abnormal VF with MD of less than -12dB in both eyes. Group 4 consisted of patients with asymmetric glaucoma damage, that is, they had one eye with severe glaucoma and the other eye normal or with mild glaucoma. All subjects completed 3 different questionnaires. Global quality of life was evaluated with EuroQol-5D (EQ-5D). Vision related quality of life was assessed with Visual Function Questionnaire (VFQ-25). Quality of life related to ocular surface disease was measured with Ocular Surface Disease Index (OSDI).

RESULTS:

VFQ-25 showed that group 3 had significantly lower scores than group 1 in mental health (P=.006), dependence (P=.006), colour vision (P=.002), and peripheral vision (P=.002). EQ-5D showed no significant differences between any group, but a trend was found to greater difficulty in group 3 than in groups 1 and 2, and in all dimensions. OSDI showed a higher score, or which was the same as a major disability, in groups 2 and 3 than group 1 (P=.021 and P=.014, respectively). VFQ-25 only found significant differences between group 1 and group 4. Dimensions with significant differences were found between group 1 and 3 (both eyes with advanced or moderate glaucoma). These were not found between group 1 and group 4 (the group in which one eye has only mild glaucoma or no glaucoma). This finding confirms that the eye with less glaucoma damage determines the quality of life.

CONCLUSIONS:

Our results demonstrate that quality of life is impaired in patients with glaucoma, and this alteration is greater the more advanced is glaucoma damage in the best or both eyes.
