Özet
Background: Diagnosis and management of hypertension is complicated by the fact that blood pressure (BP) varies greatly depending on various stresses. In the doctor's office in particular, measurements are often too high, which is defined as white coat hypertension (WCH). Although already known to have a high prevalence in society, prognostic significance of WCH remains controversial. Methods: We studied consecutive patients with WCH and sustained normotension (NT) at and over the age of 50 years just to catch, if found, the long term effects of WCH on eyes. Funduscopic examination was performed by the same ophthalmologist who was unaware of the patients' subclassification. Keith, Wagener, and Barker's classification of hypertensive retinopathy (HR) was used to define the funduscopic findings. Results: Fifty-six WCH and 51 sustained NT cases were studied. No case of grade III or IV HR was observed in either group. Eight cases of grade I HR (14.2%) were detected in the WCH group, whereas this ratio was 9.8% (five cases) in the sustained NT group (p>0.05). Similarly, although three cases of grade II HR (5.3%) were detected in the WCH group, this ratio was 3.9% (two cases) in the sustained NT group (p>0.05). Conclusion: As a result of nonsignificant differences between WCH and sustained NT groups according to funduscopic findings, and the already known high prevalences of WCH in society even in early decades, WCH should be considered as a response of the body against some metabolic stresses, and its follow up about progression to HT should be performed with regular home BP measurements.
