Objective To investigate the therapeutic effects of retinal angioma. Methods The clinical data of 16 cases(20 eyes) were retrospectively analyzed, and the patients included 5 males and 11 females of 23.3 yeras old on average. Four cases in this series affected by bilateral retinal angiomas were identified as von Hippel-Lindou disease. The retinal angiomas were divided into 5 stages according to their degrees of developmnet from simple angiom without vessel dilation to feeder vessel dilation and intraretinal exudates, local retinal detachemnt, massive retinal detachment and complication occurrence in proper order. The methods of treatment were laser photocoagulation, trans-scleral cryotherapy and vitreoretinal surgery. The patinets were followed up for 37.8 months on average. Results There were 10 eyes(2 in stage 1, 7 in stage 2, 1 in stage 3)treated with laser photocoagulation, and all of the angiomas were controlled after the treatment. The visual acuity improved in 2 eyes, decreased in 4 eyes, and remained unchanged in 4 eyes. Cryotherapy was performed on 7 eyes(5 in stage 3, 2 in stage 4). The visual deteriortion was found in 5 eyes; and the state of illness was stable in 3 eyes in stage 3 and aggravating in 4 eyes (2 in stage 3, 2 in stage 4). Vitreoretinal surgery was performed on 4 eyes including 2 which had been gi ven photocoagulation, and the visual acuity improved in 2 eyes, decreased in 1 eye, and was unimproved in 1 eye. The visual acuity decreased to no light perception in an untreated eye after 1.5-year follow-up. New angiomas occurred in 3 eyes with Von-Hippel-Lindou disease in the follow-up period. Conclusion Laser photocoagulation is effective in treating the angiomas from stage 1 to 3. Cryotherapy can cause massive exudation and proliferation, and it is only suitable for a few patients in stage 3. The visual prognosis is more favorable in vitreoretinal surgery than other therapies for the patients in stage 4.

Objective To evaluate the clinical features of 18 cases of juxtapapillary capillary hemangioma. Methods In 18 cases of juxtapapillary capillary hemangioma, the clinical data of 19 eyes, the results of fundus fluorescein angiography (FFA) of 16 eyes, and the follow-up observation of 7 eyes were retrospectively analyzed. Results In 18 cases, the sex ratio of male and female is 1∶2 with the average age of 28.9 years. Peripheral retinal angioma was found in 3 cases (4 eyes). In 19 eyes, the center of hemangioma was located beyond the rim of optic, most of which was in inferotemporal quadrant of the optic (7/19) with the size of 1-2.5 disc diameter (DD). Most of the tumors were red in color (12/19). In the result of FFA of 16 eyes, wash-out at the late phase was found in 13 eyes. Decreased acuity was found in all 7 cases that were followed up more than 12 months (including 5 cases treated by laser photocoagulation). Retinal detachment didn′t occur in 6 cases without exudative retinal detachment after being followed-up for 54.5 months of the average term. Conclusions Most of the juxtapapillary capillary hemangioma are orange or red oval tumors. The center of hemangioma are located beyond the rim of the optic. The patients often complain gradually decreased visual acuity when they are in prime of their life with exudation and edema in different degree around the tumor. FFA is helpful for the diagnosis and differential diagnosis of this disease.

Objective To explore the clinical value of high-frequency color Doppler ultrasound in the diagnosis of isolated calf muscle vein thrombosis (ICMVT). Methods Sonographic features of 175 patients with isolated calf muscular venous thrombosis were analyzed retrospectively and outcome of anticoagulant therapy in 1, 3, and 6 months was followed up. Diagnosis was established with high-frequency color Doppler ultrasound examination. Results One hundred and seventy-ifve patients presenting with 190 calf muscle vein thrombosis were included. One hundred and iffty-eight cases with 173 calf muscle vein thrombosis were diagnosed by high-frequency color Doppler ultrasound, 7 cases of misdiagnosis, missed diagnosis in 10 cases. The accuracy rate was 91.1%(173/190). Seven cases were misdiagnosed with 1 euroifbromatosis, 1 mixed hemangioma, 5 gastrocnemius hematoma. After diagnosis of ICMVT, all patients prescribed thrombolysis and anticoagulation therapy. High-frequency color Doppler ultrasound for 1, 3, 6 months after treatments revealed partial or complete recanalization without calf deep vein thrombosis. Typical sonographic features included:calf muscle venous lumen dilation, tortuous anechoic lumen or hypoechoic iflling, with tubular or branched shape in the longitudinal view and oval or round shape in the transversal view. Conclusion High-frequency color Doppler ultrasound is an accurate and reliable method in the diagnosis of the isolated calf muscular venous thrombosis.
