Choroidal Venous Pulsations at an Arterio-venous Crossing in Polypoidal Choroidal Vasculopathy
Akiko Okubo,Munefumi Sameshima,Taiji Sakamoto 대한안과학회 2013 Korean Journal of Ophthalmology Vol.27 No.5
It has been reported that pulsations in abnormal vessels are observed on indocyanine green (ICG)angiography in half of patients with polypoidal choroidal vasculopathy (PCV), although the mechanism of the pulsation is unknown. In this study, we report a case of PCV showing venous pulsations at an arteriovenous (A-V) crossing, and discuss a possible mechanism of polypoidal vessel formation and pulsations in PCV. A 66-year-old female presented with a reddish-orange elevated lesion and serous retinal detachment in the macula of her left eye, and was diagnosed as PCV. She was treated with photodynamic therapy (PDT),and followed-up through routine examinations, including ICG angiography. ICG angiography at presentation showed a branching vascular network and choroidal venules with dye leakage (polypoidal vessels) in the left eye. Pulsations, supposedly of venous origin, were observed at an A-V crossing in the abnormal vessels. Within 3 months after PDT, the polypoidal vessel ceased to leak and the pulsations vanished. The reddish-orange lesion gradually decreased in size with complete disappearance of retinal detachment. This study suggests that an unusual compression at an A-V crossing may make a venule polypoidal, and fluctuations of blood flow and pressure in the venule may cause pulsatile movements of the vessel wall.

A Case of Muir-Torre Syndrome with Multiple Cancers of Bilateral Eyelids and Breast
Taro Kamisasanuki,Eisuke Uchino,Jun-ichi Fukushima,Hiroshi Yoshikawa,Tatsuro Ishibashi,Taiji Sakamoto 대한안과학회 2013 Korean Journal of Ophthalmology Vol.27 No.3
We report a case of Muir-Torre syndrome (MTS) with a very rare combination of cancers, involving bilateral eyelid cancers and breast cancer. A 71-year-old female with a history of breast cancer from 18 years prior presented with bilateral eyelid tumors. One of her siblings had lung cancer, and another had pancreatic cancer. She underwent excisional biopsy of the eyelid tumors and histopathology revealed sebaceous carcinoma of the right eyelid and basal cell carcinoma of the left. She was diagnosed with MTS: a skin cancer associated with visceral malignancy. Immunohistochemical tests for mutS homolog 2 showed a lack of expression in both eyelid carcinomas.
