[Vascular profile of patients with normal tension glaucoma].

BACKGROUND

Glaucoma can be caused by multiple factors essentially the vascular factors.

AIM

The aim of this article is to study the vascular profil of patients with normal tension glaucoma in the purpose to better understanding his pathogenesis and to making appropriate therapeutic decision.

METHODS

39 patients with normal tension glaucoma were investigated. Each patient had complete ophtalmologic examination with visuel field examination, a medical examination, a biological investigation and a vascular supraaortic doppler.

RESULTS

One or several vascular risk factor are found in the majority of our patients. 25% of the patients aggravate their visuel fiel. 40% are diabetic, 56% are hypertensive, 40% have a lipidic disturbance and 30% have a vasospastic syndrom.

CONCLUSION

Vascular risk factors play an important role in the physiopathology of normal tension glaucoma, and the prognosis depend on the treatment of these factors.
