Retinal Vein Occlusion Overview
Retinal vein occlusion, one of the most frequently occurring retinal vascular disorders in elderly patients, develops predominantly in individuals over age 65 years. The main risk factors for RVO include age and systemic vascular disorders. It is categorized into central RVO (CRVO) and branch RVO (BRVO) according to the site of blockage in the retinal vein. CRVO is divided further into nonischemic and ischemic types according to the perfusion status based on fluorescein angiography. BRVO consists of major branch RVO (when one of the major branch retinal veins is occluded, usually near, or rarely at, the optic disc) and macular branch RVO (when only one of the macular venules is occluded).Macular edema is the major complication of significant visual loss in patients with CRVO and BRVO, and various treatments have been used to improve macular edema and cause regression of intraocular neovascularization.
The initial examination of a patient with an RVO includes all relevant aspects of the comprehensive adult medical eye evaluation, with particular attention to those aspects related to retinal vascular disease. Several tests are being used for the diagnosis of RVO such as Optical coherence tomography (OCT), and fluorescein angiography (FA). Apart from this, Systemic evaluation is often performed in patients with CRVO and is directed by the patient's age, coexisting risk factors, and medical history. In RVO, intravitreal steroids and anti-VEGF therapy are used in cases of macular perfusion and macular ischemia, with the laser of use in situations of neovascularization. Response to treatment may be measured by improvement of visual acuity (as a measure of photoreceptor status) and retinal thickness (as a measure of leakage).Growth of the RVO market is expected to be mainly driven by an increase in the number of geriatric people, an increase in market penetration of emerging therapies, readily uptake of current as well as emerging therapies with patient convenient RoA, and increasing awareness about this disease.
Retinal Vein Occlusion Diagnosis
The initial examination of a patient with an RVO includes all relevant aspects of the comprehensive adult medical eye evaluation, with particular attention to those aspects related to retinal vascular disease. An initial history should consider such as the location and duration of vision loss, current medications, medical history and ocular history.
The initial examination includes visual acuity, pupillary assessment for a relative afferent pupillary defect that corresponds to the level of ischemia and is also predictive for eyes at risk for neovascularization, slit-lamp biomicroscopy, looking carefully for fine, abnormal, new iris vessels, IOP, gonioscopy, the examination of the peripheral retina and vitreous and binocular funduscopic evaluation of the posterior pole.
If used appropriately, several imaging tests may enhance the clinical examination and optimize patient care. The most common tests include the following: Optical coherence tomography: optical coherence tomography provides high-resolution imaging of the macula. it is extremely useful to detect the presence and extent of any associated macular edema, vitreoretinal interface changes, and subretinal fluid, Fluorescein angiography: is used to evaluate the extent of the vascular occlusion, the degree of ischemia (ischemic as defined by the CVOS eyes with 10 disc areas of capillary nonperfusion on standard FA vs. nonischemic), and the extent of macular edema. Angiography can identify macular capillary nonperfusion that may explain the associated vision loss as well as the response to therapy, Systemic evaluation: is often performed in patients with CRVO and is directed by the patient's age, coexisting risk factors, and medical his¬tory. Assessment should be performed in conjunction with an internist, as patients with RVO may be at higher risk of cardiovascular disease and cere¬brovascular accidents.
Retinal Vein Occlusion Treatment
A person suffers from RVO when one of the veins in the retina becomes blocked. It may lead to varying degrees of vision loss, depending on the severity and location of the blockage. Currently, some of the treatments for retinal vein occlusion include: Intravitreal Injection of Anti-Vascular Endothelial Growth Factor (VEGF) Drugs, Intravitreal Injection of Corticosteroid Drugs, Focal Laser Therapy, and Pan-Retinal Photocoagulation Therapy.
Intravitreal injections are used to administer medications to treat a variety of retinal conditions. Age-related macular degeneration (AMD), diabetic retinopathy, and RVO are the most common conditions treated with intravitreal anti-VEGF drugs. In addition to this, Intravitreal steroids are also used in diabetic retinopathy, RVO, and uveitis. The anti-VEGF drugs and steroids help reduce fluid leakage associated with these disorders. At present, Anti-VEGF drugs are markedly more effective in the treatment of RVO than any other treatment modality. Among all the available treatment choices, anti-VEGF drugs provide the greatest improvement in VA. 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. Steroid injections are another option which acts to reduce the inflammation in the retina caused by the RVO. Corticosteroids have anti-inflammatory, antiangiogenic, and anti-permeability properties that make them an attractive therapeutic option for a variety of posterior segment diseases. While steroids may be considered in patients with systemic cardiovascular risk, surgery remains advisable only for very few patients.

Retinal Vein Occlusion Emerging Technique
TLC399 (ProDex): Taiwan Liposome Company
TLC399 is the proprietary BioSeizer formulation of dexamethasone sodium phosphate (DSP), intended as an intravitreal, or in-eye, injection for the treatment of macular edema due to retinal vein occlusion. TLC399 in preclinical models has been shown to provide therapeutic levels of DSP in the eye for at least six months after a single administration and have also demonstrated its potential to decrease the thickness of the retina and improve vision. A phase I/II safety trial has demonstrated encouraging signs of efficacy in both the reduction of retinal central subfield thickness and improvements in visual acuity. A larger randomized, double-blind, dose-finding phase II trial is underway. The company is also evaluating opportunities to develop TLC399 in diabetic macular edema in combination with intravitreal anti-VEGF drugs.
GB-102: Graybug Vision
GB-102 is an intravitreal, microparticle depot formulation of the anti-VEGF sunitinib. Sunitinib is a small molecule receptor tyrosine kinase inhibitor that acts as a potent inhibitor of all VEGF pathways, which are known to cause angiogenesis and vascular leakage in the retina, leading to vision decline. The VEGF pathways play an influential role in the development and progression of wet AMD, and there is mechanistic and clinical evidence indicating that a more complete inhibition of these pathways, as offered by sunitinib, could lead to superior patient outcomes compared to current treatments that target only limited VEGF pathways, specifically VEGF-A. The company believes that extending the duration of treatment while expanding the spectrum of neovascular inhibition of all VEGF pathways is differentiated from the current standard of care and may lead to better patient outcomes (Graybug Vision).

Retinal vein occlusion (RVO) is a common vascular disorder of the retina and one of the most common causes of vision loss worldwide. Specifically, it is the second most common cause of blindness from retinal vascular disease after diabetic retinopathy.
There's no medication available that's specific for retinal artery occlusions. Most people with this condition will have permanent changes to their vision. The main goal of treatment is to stabilize vision by sealing off leaking blood vessels.
Unfortunately, there is no way actually to unblock retinal veins. However, the doctor can treat any health problems that seem to be related to RVO. Vision may come back in some eyes that have had an RVO. About one-third have some improvement, about one-third stay the same and about one-third gradually improve, but it can take a year or more to learn the outcome. In some cases, the blocked vessels will lead to fluid accumulation in the retina, like sponges absorbing water. In others, they may cause the formation of new blood vessels. The current treatment options of RVO intend to minimize the damage, as there is no proven treatment to improve vision loss in the long term. The therapy aims to prevent further visual loss and its complications, such as macular edema, ischemia, or neovascularization.
Some of the treatments for RVO include Intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs. These drugs target VEGF, which is an important growth factor that causes macular edema. Intravitreal injection of corticosteroid drugs is the type of drug to combat the inflammatory components which lead to edema. Intraocular injections of steroids are another potential treatment for eyes that don't respond to anti-VEGF drugs. While intraocular steroids can have some side effects such as an increase in eye pressure and cataract progression, in most cases, these side effects can be controlled.
Focal laser therapy is another type of treatment that provides lasers to areas of swelling to cause a reduction in edema. Laser treatment may also be used along with anti-VEGF therapy in hard-to-treat cases. Laser therapy for macular edema involves applying light laser pulses to the macula in a grid pattern. Pan-retinal photocoagulation therapy is also a treatment option that is used when patients have new blood vessel formation following the RVO.
Several other treatment strategies focus on the surgical treatment of the occluded retinal vein. Some of the approaches include radial optic neurotomy, chorioretinal venous anastomosis, vitrectomy with or without internal limiting membrane peeling, and others.
Currently, there are only three FDA approved products for RVO treatment, including Lucentis (ranibizumab, Genentech), Eylea (aflibercept, Regeneron), Ozurdex (dexamethasone intravitreal implant, Allergan Pharmaceuticals) while Avastin is used as an off-label therapy that help in maintaining or improving the vision.
According to DelveInsight, the RVO market is expected to change in the study period 2017-2030.
