Retinal vein occlusions are the second most common form of retinal vascular disease. Previously, laser treatment for branch retinal vein occlusion and intravitreal triamcinolone acetonide for central retinal vein occlusion were the standard of care. Recent studies have demonstrated that anti-vascular endothelial growth factor (anti-VEGF) agents have a superior safety and efficacy profile for the treatment of both branch and central retinal vein occlusions. The use of wide-field fluorescein angiography has also allowed better visualization of the retinal periphery...

Retinal vein occlusion (RVO), including central (CRVO), branch (BRVO) and hemicentral and hemispheric RVO, is the second most common vascular cause of visual loss, surpassed only by diabetic retinopathy. The presence and extent of retinal ischemia in RVO is associated with a worse prognosis. On this basis, most previously conducted studies considered iRVO and non-iRVO as separate entities based on set thresholds of existing retinal ischemia, as determined by fundus fluorescein angiography (FFA). Other diagnostic technologies have been used specifically in the differentiation of iCRVO and non-iCRVO...

In this report, we describe three cases of retinal macrovessel. Two of the three patients presented to our clinic for annual eye exam and had no visual complaints. The third patient presented because of vision loss in the left eye. Two patients had 20/20 best corrected visual acuity in both eyes and the third patient had 20/20 in the right eye, 20/25 in the left eye. Pupillary exams were normal. Slit-lamp examinations of the anterior segment were unremarkable. Fundus examination revealed macrovessels in the left eyes of two patients and in the right eye of one patient...

Anti-vascular endothelial growth factor agents reduce macular edema and improve vision in eyes with macular edema associated with retinal vein occlusion (RVO), including branch RVO (BRVO) and central RVO. However, not all eyes with resolved macular edema show satisfactory best corrected visual acuity. Photoreceptor impairment can mostly explain the vision loss in these cases. Photoreceptor damage can be caused by subretinal hemorrhage in the central fovea and hard exudates or their precursor derived from concentrated lipoproteins originating from leaky retinal vessel extravasation...

AIM: To determine whether there is a significant correlation between the reduction in macular vessel density and the recurrence of macular oedema in eyes with branch retinal vein occlusion (BRVO). METHODS: We reviewed the medical records of 27 eyes with macular oedema associated with BRVO. All eyes had received pro re nata intravitreal ranibizumab (IVR) injection. A reinjection of ranibizumab was performed when the central foveal thickness was ≥300 µm. At 12 months, patients without additional IVR for the last 4 months were placed in the resolved group, otherwise they were placed in the recurrence group...

BACKGROUND/AIMS: To characterise neuroretinal atrophy in retinal vein occlusion (RVO). METHODS: We included patients with central/branch RVO (CRVO=196, BRVO=107) who received ranibizumab according to a standardised protocol for 6 months. Retinal atrophy was defined as the presence of an area of retinal thickness (RT) <260 µm outside the foveal centre. Moreover, the thickness of three distinct retinal layer compartments was computed as follows: (1) retinal nerve fibre layer to ganglion cell layer, (2) inner plexiform layer (IPL) to outer nuclear layer (ONL) and (3) inner segment/outer segment junction to retinal pigment epithelium...

A dexamethasone (DEX) intravitreal implant (OZURDEX) provides an effective treatment of inflammation secondary to branch retinal vein occlusion (BRVO). Retinal proteome changes which mediate the beneficial effects of the implant remain poorly understood. To study retinal proteome changes in BRVO following an intervention with a DEX implant this study combined an experimental model of BRVO with proteomic techniques. In eight Danish Landrace pigs experimental BRVO was induced in both eyes using argon laser. After inducing BRVO a DEX implant was injected into the right eye of each animal while the left control eye was given an identical injection without an implant...

BACKGROUND: To evaluate the change in peripheral perfusion status in patients with retinal vein occlusion (RVO) during dexamethasone treatment. METHODS: Thirty-five eyes of patients with macular oedema due to either branch or central retinal vein occlusion were included. At baseline, patients were treated with an intravitreal dexamethasone implant (Ozurdex® ) and followed until month 6. Wide-field angiographies were classified as ischaemic and nonischaemic. Peripheral nonperfusion (PNP) was determined manually by calculating the percentage of nonperfusion area in relation to the total visible retina (ischaemic index)...
