Potential reservoir for the accumulation of extravascular fluid due to the thickness and loose binding of inner connecting fibers in the outer plexiform layer
Central avascular zone creating a watershed arrangement between the choroidal and retinal circulation thus decreasing resorption of extracellular fluid.

Macular Edema is a common cause for vision loss in Retinal Vein Occlusion
• Pathogenesis
• Involves release of cytokines mediating the angiogenic & inflammatory processes
• Dysregulation of endothelial tight junction proteins
• Increased vascular permeability & further release of inflammatory mediators including IL-1, TNF-alpha, VEGF and others

Conclusions from CRUISE and HORIZON studies:Limitations of anti-VEGF treatment
● Macular hypoxia is not alleviated with anti-VEGF
● Requires multiple injections over extended periods (average 8-9 injections over 12 months).
● If you inject less frequently you can lose vision.
● Not all people gain vision
● Some people lose vision
● Side effects are low but not zero

• Patients in each study were classified according to their OCT characteristics at baseline into 3 groups• CFT ≤250 µm• Intraretinal cysts of fluids (CME)• Subretinal fluid (SRF)
• Patients were assessed for the effect of ranibizumab on these OCT parameters as well as on their visual acuity outcome at 6 and 12 months

● Average OCT improved approximately 200 µm with each injection
● 69% of patients required an Ozurdex® between 4-6 months
● 80% did not need an anti-VEGF within 3 months after the injection
● At baseline, 31.5% of patients had glaucoma/OHT, 15.6% had a history of IOP response to steroids, yet <5% of patients had clinically elevated IOP at their final visit

SHASTA Study: Conclusions
• Clinical use of 2 or more dexamethasone implants, either alone or in combination with anti-VEGF treatments, is safe and effective in the treatment of macular edema following RVO if IOP increases are monitored and treated
• Decreases in macular edema and improvements in visual acuity were maintained with ongoing dexamethasone implant treatment
• No new safety concerns developed after the use of multiple implants
• There was no evidence of a cumulative effect of repeat dexamethasone implants on IOP
• Clinical use of 2 or more dexamethasone implants, either alone or in combination with anti-VEGF treatments, is safe and effective in the treatment of macular edema following RVO if IOP increases are monitored and treated
• Decreases in macular edema and improvements in visual acuity were maintained with ongoing dexamethasone implant treatment
• No new safety concerns developed after the use of multiple implants

RVO Conclusions
● Consider treatment with multimodalities:
● Gain benefits of each and reduces side effects of both
● Potentially helps improve outcomes

Evaluation of Therapies for CRVO
● Can a corticosteroid “rescue” eyes that are failing anti-VEGF therapy with aflibercept?
● Can anti-VEGF therapy with aflibercept “rescue” eyes that are failing treatment with bevacizumab?

* Poor or marginal response: (1) Visual acuity letter score less than 58/less than 20/80) OR visual acuity letter score improvement of ≤5 from baseline (ie, Month 6 visual acuity letter score – Baseline visual acuity score <5 letter). [Note that at least some of the visual acuity deficit is attributed, by the investigator,
to macular edema secondary to CRVO] AND (2) OCT has 1 or more of the following: central subfield thickness of ≥300 µm on SD-OC-OCT (or ≥320 µm if measured on Heidelberg Spectralis Machine), presence of intraretinal cystoid spaces, subretinal fluid.
Good response: Otherwise
