Long-term results after low dose ocular irradiation for choroidal haemangiomas.
AIM/BACKGROUND The most common choice of treatment for choroidal haemangiomas (CH) in the past has been the employment of scatter photocoagulation of the surface. This management often requires repetitive treatment or additional invasive management due to massive exudative detachment of the retina. The aim of this retrospective study was to investigate the outcome of the alternative application...
متن کاملLong-term results of low-dose proton beam therapy for circumscribed choroidal hemangiomas.
PURPOSE To evaluate the long-term efficacy and outcome of low-dose proton beam irradiation in the treatment of symptomatic circumscribed choroidal hemangioma. PATIENTS AND METHODS Retrospective review of 71 patients with symptomatic circumscribed choroidal hemangiomas treated by proton beam irradiation between September 1994 and October 2002 using a total dose of 20 Cobalt Gray Equivalent. ...
متن کاملLow dose hypersensitivity after high-LET irradiation
An unexpected hypersensitivity has been reported for several cell lines at low doses (<1Gy), which is not consistent with the linear-quadratic approach currently used in general for the description of survival curves [1,2,3,4]. The corresponding substructure of the survival curves has been attributed to induced radioresistance. There are indications, that high-LET irradiation with neutron or pi...
متن کاملUp-regulation of calreticulin in mouse liver tissues after long-term irradiation with low-dose-rate gamma rays
The biological effects of low-dose or low-dose-rate ionizing radiation on normal tissues has attracted attention. Based on previous research, we observed the morphology of liver tissues of C57BL/6J mice that received <50, 50-500, and 500-1000 μGy/h of 137Cs radiation for 180 d. We found that the pathological changes in liver tissues were more obvious as the irradiation dose rates increased. Add...
متن کاملLong-Term Changes in Subfoveal Choroidal Thickness After Cataract Surgery
BACKGROUND Cataract surgery is associated with the development of late-onset age-related macular degeneration (AMD). The pathogenic mechanism is still not fully established. The purpose of this study was to evaluate the possible changes in central macula thickness (CMT) and subfoveal choroid thickness (SCT) after uneventful cataract surgery. MATERIAL AND METHODS A total of 65 eyes of 65 patient...
