Gastrointestinal stromal tumor (GIST) is the most common sarcoma of the gastrointestinal tract with around 5000 new cases per year. Outcomes for patients with GIST dramatically improved after the development of tyrosine kinase inhibitors targeted against the aberrant signaling pathways that drive GIST oncogenesis. Majority of patients derive benefit from first-line imatinib, and the type of driver mutation is predictive of response. However, almost half of the patients eventually develop resistance to initial targeted therapy and further lines of treatment do not have the same impact...

Central retinal vein occlusion (CRVO) is a common retinal vascular disorder that can result in severe visual acuity loss. The randomized control study, CRUISE, helped establish anti-VEGFs as the standard of care in cases with CRVO. The extension studies for CRUISE; HORIZON and RETAIN showed that not all visual gains are maintained beyond the first year. In addition, patients showed different behavior patterns; with some patients showing complete response with few recurrences, whereas others showed partial or even no response with multiple recurrences...

BACKGROUND: SD-OCT is an important tool in the diagnosis of macular oedema (ME) due to retinal vein occlusion (RVO). Its high resolution makes it possible to distinguish various morphological characteristics and differences. The aim of this study is to evaluate the correlation between morphological patterns and the development of visual acuity (VA) after intravitreal treatment of ME due to RVO. METHODS: 81 patients on intravitreal treatment (dexamethasone: n = 53/ranibizumab: n = 28) due to ME associated with branch and central retinal vein occlusion ( BRVO: n = 38/CRVO: n = 43) were retrospectively reviewed...

With the current widespread use of anti-VEGFs in the treatment of central retinal vein occlusion (CRVO), the role for steroids has become greatly diminished. Recent large scale randomized control trials (RCTs) have established the efficacy and safety of anti-VEGFs in the treatment of CRVO. Steroids are known to cause elevations in intraocular pressure as well as increase the risk of cataract formation. With that in mind many ophthalmologists are injecting steroids less frequently. This paper aims to review some of the data pertaining to the use of steroids either as a first line monotherapy, adjunct therapy, or an alternative therapy to help answer the question: Is there currently any role for steroids in the management of CRVO?...

BACKGROUND: Central retinal vein occlusion (CRVO) is a common retinal vascular abnormality associated with conditions such as hypertension, diabetes, glaucoma, and a wide variety of hematologic disorders. Macular edema (ME) represents an important vision-threatening complication of CRVO. Intravitreal steroids (IVS), such as triamcinolone acetonide, have been utilized to treat macular edema stemming from a variety of etiologies and may be a treatment option for CRVO-ME. OBJECTIVES: To explore the effectiveness and safety of intravitreal steroids in the treatment of CRVO-ME...

BACKGROUND: The availability of new therapeutic approaches, particularly intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapies, has prompted significant changes to the established treatment paradigms for retinal vein occlusion (RVO). Better visual outcomes and significantly lower rates of adverse events have been noted in multiple large randomized clinical trials and have led to a new standard of care for this sight-threatening condition. OBJECTIVE: To develop an expert consensus for the management of RVO and associated complications in the context of recent clinical evidence...

Retinal vein occlusion (RVO) is the second most common cause of visual loss in the Western World. RVO is usually classified into branch RVO (BRVO) and central RVO (CRVO) according to the anatomical site of the vascular occlusion. The pathogenesis of RVO is not yet fully understood, however an important event is the intraluminal thrombus formation, which is usually secondary to several conditions such as hypertension, hyperlipidemia, diabetes and thrombophilia. The blockage of venous circulation causes an elevation of intraluminal pressure in the capillaries, leading to hemorrhages and leakage of fluid within the retina, increase of interstitial pressure and a consequent reduction of retinal perfusion...

Aflibercept is a new anti-vegf drug that, unlike ranibizumab and bevacizumab blocks both vegf-A and placental growth factor. Moreover, it binds with much greater strength and affinity to human VEGF-A165 than other endogenous vegf receptors, conferring it with a more extended effect and allowing a lower frequency of intravitreal injections. This facilitates the adoption of fixed treatment regimens other than monthly or individual regimens such as "treat and extend". Aflibercept is indicated for the treatment of neovascular (exudative) age-related macular degeneration (ARMD), visual alteration due to macular edema secondary to central retinal vein occlusion (CRVO) and visual alteration due to diabetic macular edema (DME)...
