Abstract

PURPOSE
To compare the clinical symptoms and signs of primary vascular dysregulation (PVD) for unilateral and bilateral eye involvement in normal tension glaucoma (NTG).
METHODS
The authors administered a questionnaire to assess PVD in patients with NTG. The answers to the 10-item questionnaire (cold hands, migraine, sleep latency, thirst, hypotension, orthostatic hypotension, emotional stress, drug sensitivity, vertigo, and systemic vasospasm) were compared between patients with unilateral involved NTG and bilateral involved NTG (N=61). The groups were classified again according to age (criteria: 55 years), sex, and mean deviation via standard automated perimetry (criteria: -6 dB).
RESULTS
The answers to the questionnaire between patients with unilateral involved NTG and bilateral involved NTG were not different at the level of statistical significance. In groups classified according to age, sex, and mean deviation, none of the answers to the questionnaire were different at the level of statistical significance between the groups.
CONCLUSIONS
Clinical symptoms and signs of PVD were not different between patients with unilateral or bilateral eye involvement in NTG. Systemic vascular factors may not be considered different between unilateral and bilateral eye involvement in NTG.
