Unlabelled:
Capillary microscopy is a non-invasive method, without any risk, easy to assess a microvascular abnormalities and influence of therapeutic methods. The aim of the study was to assess in conventional in vivo capillary microscopy a microvascular condition and its abnormalities in nail bed in patients with diagnosed rosacea in various clinical stages.
Material And Methods:
16 female patients with diagnosed rosacea have undergone the clinical and capillary microscopic examination. The results were compared with healthy group of volunteers (16 females) . The results of clinical and microvascular studies in observed patients were shown.
Results:
The age of patients with rosacea was between 20 and 70 years, average age was 49.38 years (SD 12.81 years). In the volunteers group the average age was 38.75 years, SD 9.48 years (min. 27, max. 55 years). A clinical type was categorized due to Plewig and Kligman classification. In the I stage there were 4 persons, in II--9 and in III phase--3 patients. The mean duration of rosacea was 5.56 years (SD 4.7 years). In the capillaroscopic examination in all patients with rosacea atypical capillaries were found. The abnormal capillaries were present in 10 volunteers (63%). In the rosacea group the most common occurred: Raynaud loops in 10 cases (62.5%), meandering capillaries and their elongation also in 10 patients (62.5%) and increasing number of the capillaries in 13 examined persons (81.25%). In the control group the presence of stenosed capillaries was confirmed in 3 examined persons (18.75%) with good visualized subpapillary venous plexus also in 3 cases (18.75%). In the rosacea group abnormalities of the color of the visual area were proved in 14 cases (88%) with indistinct field of vision in 3 cases (19%). In the control group the color of field of vision was normal in 11 examined persons (69%) and no abnormalities of visual area acuity were reported.
Conclusion:
Examination proved that conventional capillaroscopy seems to be a new diagnostic method in rosacea.
