Assessment of Spontaneous Retinal Arterial Pulsations in Acute Central Retinal Vein Occlusions.

ABSTRACT: Central retinal vein occlusion (CRVO) is a common retinal disease. Recent works mentioned spontaneous retinal arterial pulsations (SRAPs) as a feature of some CRVOs. This is a retrospective study on patients presenting with CRVO who were followed up for at least 6 months. The objective was to identify SRAP in the acute phase of the disease and determine their relationship with patients' characteristics and visual prognosis. A 10-second infrared film centered on the optic disc was recorded within a month of the onset of symptoms, and SRAPs were detected in two-thirds of the cases. Patients with SRAP were significantly younger than those without SRAP. Mean central macular thickness was significantly higher in the absence of SRAP, which was translated into a more severe macular edema; however, this difference faded with time. BCVA tended to be higher in the presence of SRAP at the 6-month follow-up when adjusted to baseline. This study demonstrates that SRAPs are a frequent finding, easily detected by infrared fundus video recording, and associated with a younger age and lesser macular edema.

Project description:BackgroundTo determine whether aflibercept (Eylea; Regeneron Pharmaceuticals, Inc., Tarrytown, NY) could continue to extend the macular edema free interval in patients on a treat and extend (TAE) with non-ischemic central retinal vein occlusions (CRVOs) previously treated with ranibizumab (Lucentis; Genentech, Inc., South San Francisco, CA) or bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA) in the second year.MethodsTwenty patients with macular edema secondary to non-ischemic CRVOs previously treated with ranibizumab or bevacizumab were prospectively treated with intravitreal aflibercept injection (IAI) using a TAE dosing regimen. Injection frequencies were extended 2 weeks if there were no signs of disease activity on OCT or change in visual acuity. In the second year of the study, patients who have recurrences of macular edema could be re-challenged with a longer treatment interval under the following criterion: absence of any macular edema on three consecutive visits with the same treatment interval.ResultsTwenty patients had an average duration of a CRVO for 22 months (range 7-90) and averaged an anti-VEGF treatment every 42 days (range 28-60 days). The macular edema free interval increased from 38 to 75 days when switched to aflibercept (p = 0.000003) at month 24. There was an average increase of 37 days (median 34 days; range 0-91 days) in the macular edema free interval with aflibercept. At the month 24 visit, 50% (8/16) went > 12 weeks with a macular edema free interval between IAI. There was an improvement in vision (+ 8 ETDRS letters, p = 0.006) and decreased retinal thickness (158 µm, p = 0.00003) with aflibercept treatment at month 24.ConclusionsThe 2-year results of the NEWTON study demonstrated the sustained benefits of a TAE dosing regimen with aflibercept in patients with chronic CRVOs. The visual acuity gains and anatomic improvements observed at year one were maintained through month 24 with less visits and treatments. This may help minimize the treatment burden in patients with recurrent macular edema secondary to non-ischemic CRVO.Trial Registration ClinicalTrials.gov, NCT01870427, Registered June 6, 2013, https://clinicaltrials.gov/ct2/show/NCT01870427?cond=NEWTON&rank=1.Presented at the RETICON 2017: The Retina Congress with Live Surgery, Chennai, India-April 2017.

Project description:PURPOSE:To test the efficacy of the intravitreal dexamethasone (DEX) implant in patients with retinal vein occlusions (RVOs) who have failed multiple anti-vascular endothelial growth factor (anti-VEGF) treatments. METHODS:A randomized exploratory study of ten patients with branch RVO or central RVO who received at least two previous anti-VEGF treatments and had persistent or unresponsive cystoid macular edema. Treatment with the DEX implant was either every 4 months or pro re nata (PRN) depending on their group assignment for 1 year. Multifocal electroretinography and microperimetry were the primary end points, with high-resolution optical coherence tomography and best-corrected visual acuity as the secondary end points. RESULTS:All patients in both the every 4 month and PRN cohorts who completed the study received the three maximal injections of DEX; therefore, the data from both cohorts were combined and reported as a case series. On average, the multifocal electroretinography amplitude increased significantly from 5.11±0.66 to 24.19±5.30 nV/deg2 at 12 months (P<0.005), mean macular sensitivity increased from 7.67±2.10 to 8.01±1.98 dB at 4 months (P=0.32), best-corrected visual acuity increased significantly from 51.0±5.1 to 55.4±5.1 early treatment of diabetic retinopathy study letters at 2 months (P<0.05), and central retinal thickness decreased from 427.6±39.5 to 367.1±37.8 ?m at 4 months (P<0.05). Intraocular pressure increased significantly in one patient, with that patient requiring an additional glaucoma medication for management. Additionally, cataract progression increased significantly (P<0.05) in this patient population and partially limited analysis of other end points. CONCLUSION:DEX should be considered as a treatment option in patients with RVOs who have failed anti-VEGF therapy, as the results of this study demonstrated an improvement in retinal morphology and macular function. Cataract progression did occur following multiple consecutive injections; however, steroid-induced glaucoma was not a limiting factor.
