RESUMO

PURPOSE: To describe the change in the retinal morphology after full macular translocation (FMT) for exudative age-related macular degeneration (AMD) and identify predictive factors for the visual outcome. METHODS: All patients who underwent FMT from December 2008 through July 2013 were selected. Exclusion criteria were FMT for other disease than AMD, age <60 years, <12 months of follow-up or no available images. Spectral domain optical coherence tomography, fundus autofluorescence, fluorangiography and indocyanine green angiography were evaluated. RESULTS: In total, 51 patients were included with a mean follow-up of 30 months. The presence of the external limiting membrane (ELM) was a significant predictor for a favourable visual outcome 1 year after FMT (OR = -0.30). Other significant predictive factors were the absence of intraretinal fluid (OR = 0.28) and the mixed choroidal neovascularization type (OR = -0.47), whereas nonresponders (OR = 0.41) and fibrotic lesions (OR = 0.35) were less likely to have a good visual function after surgery. CONCLUSION: Full macular translocation (FMT), that permits to relocate the diseased macula onto an area of unaffected retinal pigment epithelial and choroid, can restore the anatomy and visual function in some patients with AMD when the outer retina layers are not irreversibly damaged. The presence of the ELM seems to be the most reliable factor in predicting the functional outcome.

RESUMO

OBJECTIVE: Idiopathic Intracranial Hypertension (IIH) is a condition of unknown etiology frequently associated with dural sinus stenosis. There is emerging evidence that venous sinus stenting is an effective treatment. We use phase contrast cine MRI to observe changes in flow dynamics of multiple intracranial fluids and their response to different treatments in a patient with IIH. METHODS: We quantified the following parameters at the level of the aqueduct of Sylvius and the cervical C2C3: Cerebrospinal Fluid (CSF), arterial and venous flow; CSF velocity amplitude; artero-venous delay (AVD); artero-CSF delay and percentage of venous outflow normalized to total arterial inflow (tIJV/tA). Analyses were run before Lumbar Puncture (LP) (A), after LP (B), after medical therapy (C) and after venous stent placements deployed at two separate times (D and E). RESULTS: AVD and tIJV/tA improved only after CSF removal and after stent placements. CSF velocity amplitude remained elevated. Arterial flow profile showed a dramatic reduction after LP with improvement in mean venous flow. This report is the first to demonstrate interactive changes in intracranial fluid dynamics that occur before and after different therapeutic interventions in IIH. CONCLUSION: The data provide valuable information regarding changes in different fluid compartments suggesting a profound redistribution of pressures along fluid compartments after different treatments. We discuss how increased intracranial venous blood could be "tumoral" in IIH and facilitating its outflow could be therapeutic.

RESUMO

PURPOSE: To investigate the long-term outcome of full macular translocation (FMT) for neovascular age-related macular degeneration (AMD) and to identify predictive factors. DESIGN: Retrospective, uncontrolled case series. PARTICIPANTS: Patients were considered for FMT if they had low vision in the fellow eye and choroidal neovascularization (CNV) along with (1) no response to vascular endothelial growth factor (VEGF) inhibitors, (2) retinal pigment epithelium (RPE) tear, (3) subretinal hemorrhage, (4) foveal scar tissue of recent onset, or (5) CNV before the availability of VEGF inhibitors. From 2004 through 2012, a total of 255 patients underwent FMT. Exclusion criteria were patients younger than 60 years, FMT for disease other than AMD, and a follow-up of less than 12 months. METHODS: Preoperative, annual, and last distance best-corrected visual acuity (BCVA) were obtained retrospectively from patient files. Complications were recorded using funduscopy, optical coherence tomography, autofluorescence, and angiography. MAIN OUTCOME MEASURES: Distance BCVA at 1 year and 5 years after surgery and at last visit compared with preoperative BCVA. RESULTS: One hundred fifty-eight patients (mean follow-up, 45 months) were included. Median BCVA improved from 0.90 logarithm of the minimum angle of resolution (logMAR) before surgery to 0.70 logMAR 1 year after FMT (2 lines gained; P = 0.000). In a subgroup of 56 patients followed up for 5 years or more, median BCVA improved from 0.95 logMAR before surgery to 0.70 logMAR 1 year after surgery, and remained improved 5 years after FMT with a median BCVA of 0.80 logMAR (1.5 lines gained compared with preoperative BCVA; P = 0.000). The main complications were foveal RPE atrophy (n = 73; 47%) and CNV recurrence (n = 47; 30%). Foveal RPE atrophy (odds ratio [OR], 7.0), CNV recurrence (OR, 2.6), and proliferative vitreoretinopathy (PVR; OR, 17.6) were statistically significant predictors (P < 0.05) for losing 1 line or more at last visit. CONCLUSIONS: In this study, BCVA was improved up to 5 years after FMT. Foveal RPE atrophy, CNV recurrence, and PVR carried a worse prognosis. In patients who are unlikely to benefit from VEGF inhibitors, FMT can be considered for second eyes with neovascular AMD.
