purpose : to report the evaluation of the treatment response in choroidal hemangioma with application of enhanced depth imaging optical coherence tomography (edi-oct) technique case report : a 73-year-old woman with a circumscribed choroidal hemangioma in the posterior pole of her left eye underwent photodynamic therapy and intravitreal injection of bevacizumab. edi-oct obtained from the affect...

Some laboratory findings and a few case reports support the treatment of chronic venous ulcers with photodynamic therapy. We treated 19 patients with refractory chronic venous ulcers using photodynamic therapy. The ulcers healed in 15 cases (78.9%) after an average of 6.8 photodynamic therapy sessions (range 6.0-8.0). In the remaining 4 cases, the ulcers showed marked improvement after 10 photo...

OBJECTIVE The aim of this study was to assess whether or not photodynamic therapy enhanced standard antibacterial therapy in dentistry. BACKGROUND DATA Photodynamic therapy when used as an adjunct to conventional periodontal therapy kills more bacteria than when conventional periodontal therapy is used alone. MATERIALS AND METHODS To address the focused question, "Does photodynamic therapy ...

We studied coherent backscattering (CBS) of light from opal photonic crystals with incomplete band gaps. We observed a dramatic broadening of the CBS cone for incident angles close to the Bragg condition in the crystals. We modify the conventional CBS theory to incorporate Bragg attenuation resulting from the photonic band structure. By fitting the CBS data with the modified theory, we extract ...

Although the phenomenon of coherent backscattering (CBS) in nonbiological media has generated substantial research interest, observing CBS in biological tissue has been extremely difficult. Here we show that the combination of low-spatial-coherence, broadband illumination, and low-temporal-coherence, spectrally resolved detection significantly facilitates CBS observation in biological tissue an...

BACKGROUND Cervical cancer is the second most common cancer in women worldwide [1]. Photodynamic therapy has been used for cervical intraepithelial neoplasia with good responses, but few studies have used newer phototherapeutics. We evaluated the effectiveness of photodynamic therapy using Pc 4 in vitro and in vivo against human cervical cancer cells. METHODS CaSki and ME-180 cancer cells wer...

One of the recommended first-line treatments for basal cell carcinomas, actinic keratoses and Bowen's disease is photodynamic therapy. Commonly associated side- effects include pain and phototoxicity. Histamine release is a part of this reaction, but whealing urticaria follow noting photodynamic therapy has only been reported by the manufacturer. The aim of this study was to investigate the pre...
