Half-dose PDT is superior to HSML for treating cCSC, leading to a significantly higher proportion of patients with complete resolution of SRF and functional improvement.
Cerebroretinal vasculopathy, hereditary vascular retinopathy, and hereditary endotheliopathy, retinopathy, nephropathy and stroke are neurovascular syndromes initially described as distinct entities. Recently they were shown to be one disease caused by C-terminal frame-shift mutations in TREX1, which was termed 'retinal vasculopathy with cerebral leukodystrophy'. Here we defined the genetic and clinicopathologic spectrum of this clinically and pathophysiologically poorly characterized and frequently misdiagnosed fatal neurovascular disorder. We identified five different TREX1 mutations in 78 members from 11 unrelated families and by using a standardized study protocol we retrospectively reviewed and aggregated the associated clinical, neuroimaging, and pathology data. Findings were similar across mutations and families. Sixty-four mutation carriers had vascular retinopathy. Neuroimaging revealed (i) punctate, hyperintense, white matter lesions with or without nodular enhancement in 97% of them; (ii) rim-enhancing mass lesions in 84%; and (iii) calcifications in the white matter in 52%. Ninety per cent had clinical manifestations of brain disease, including focal neurological deficits (68%), migraine (59%), cognitive impairment (56%), psychiatric disturbances (42%), and seizures (17%). One mutation carrier had enhancing brain lesions and neurological features but unknown retinopathy status. Additional systemic features included liver disease (78%), anaemia (74%), nephropathy (61%), hypertension (60%), mild Raynaud's phenomenon (40%), and gastro-intestinal bleeding (27%). Mean (AE standard deviation) age at diagnosis was 42.9 AE 8.3 years and at death 53.1 AE 9.6 years. Pathological examination revealed systemic vasculopathy with luminal narrowing and multi-laminated basement membranes. The 13 mutation carriers without retinopathy or brain lesions were on average 8 years younger (mean age: 35.1 AE 10.6 years). Of them, 54% had mild Raynaud's phenomenon, 42% had migraine, and 23% had psychiatric disturbances. Retinal vasculopathy with cerebral leukodystrophy is an autosomal dominant systemic small-vessel disease due to specific TREX1 mutations and clinically primarily characterized by (i) visual impairment from vascular retinopathy; and (ii) neurological decline and premature death due to progressive enhancing cerebral white matter lesions. Impaired liver and kidney function, anaemia sometimes associated with gastrointestinal bleeding, hypertension, migraine, and Raynaud's phenomenon appear to be part of the clinical spectrum as well.

Please be advised that this information was generated on 2018-05-11 and may be subject to change.We have performed retina) fluorescein angiography and audiometry in 32 familial and 7 sporadic cases of facioscapulohumeral muscular dys trophy. A mild to moderate retinal vasculopathy, consisting of retinal teleangiectasis and microaneursyms, was present in 18 of 37 evaluable angiograms (49%); 5 patients had minimal changes and 14 angiograms (38%) were normal. High frequency hearing loss was found in 25 (64%) out of 39 patients. Retinal changes were absent in 5 of 18 families (6 cases examined), and after correction for age and sex, hearing function was normal in 5 of 19 families (7 cases examined). Age and severity of the myopathy did not have a clear relationship with the retinal vascu lopathy or the hearing loss. There were no differences between families in which the myopathy was linked to chromosome 4q35 and families in which linkage could not be proven, Minimal retinal vascular changes and high tone hearing loss can be observed occasionally in the normal population. Therefore, although retinal vasculopathy and hearing loss are part of the clinical picture of FSHD, these signs cannot be accepted as decisive criteria for FSHD in clinically equivocal cases.
PurposeTo compare the effectiveness of bevacizumab and ranibizumab in the treatment of exudative age-related macular degeneration (AMD).DesignMulticentre, randomized, controlled, double-masked clinical trial in 327 patients. The non-inferiority margin was 4 letters.PatientsPatients ≥ 60 years of age with primary or recurrent sub- or juxtafoveal choroidal neovascularization (CNV) secondary to AMD with a total area of CNV < 12 disc areas and a best corrected visual acuity (BCVA) score between 20 and 78 letters on an EDTRS like chart in the study eye.MethodsMonthly intravitreal injections with 1.25 mg bevacizumab or 0.5 mg ranibizumab were given during one year. Intention to treat with last observation carried forward analysis was performed.Main Outcome MeasuresPrimary outcome was the change in BCVA in the study eye from baseline to 12 months.ResultsThe mean gain in BCVA was 5.1 (±14.1) letters in the bevacizumab group (n = 161) and 6.4 (±12.2) letters in the ranibizumab group (n = 166) (p = 0.37). The lower limit of the 95% confidence interval of the difference in BCVA gain was 3.72. The response to bevacizumab was more varied; 24% of patients showed a gain of ≥15 letters, 11% a loss of ≥15 letters and 65% a gain or loss < 15 letters compared to 19%, 5% and 76% respectively for ranibizumab (p = 0.038). No significant differences in absolute CRT and CRT change (p = 0.13) or in the presence of subretinal or intraretinal fluid (p = 0.14 and 0.10, respectively) were observed. However, the presence of any fluid on SD-OCT (subretinal and/or intraretinal) differed significantly (p = 0.020), with definite fluid on SD-OCT in 45% of the patients for bevacizumab versus 31% for ranibizumab. The occurrence of serious adverse events and adverse events was similar, with 34 SAEs and 256 AEs in the bevacizumab group and 37 SAEs and 299 AEs in the ranibizumab group (p = 0.87 and p = 0.48, respectively).ConclusionsBevacizumab was not inferior to ranibizumab. The response to bevacizumab was more varied with higher percentages of both gainers and losers and more frequently observed retinal fluid on SD-OCT at 12 months when compared to the ranibizumab group.Trial RegistrationTrialregister.nl NTR1704
