The first FDA cleared OCT Angiography technology ZEISS AngioPlex

The newest advances in angiography is OCT-A. There is far less risk to the patient because there is no need for dye to be injected, which eliminates the possibility of an allergic reaction. The photographer can concentrate on the quality of the captured images since there is no need to hurry to take the photographs before the dye is absorbed. For the same reason, this imaging is easier to reproduce than fluorescein angiography.

Please note that, “FA imaging of the radial peripapillary network, deep retinal capillary plexus and choroidal vasculature is poor.³ FA image interpretation is based on dynamic properties of dye leakage, staining and blockage.^{” http://www.retina-specialist.com/article/will-oct-angiography-replace-fa}

^{The FA technique can be limited by its more expensive technical requirements, time constraints, invasive nature and risk of allergic reaction to the fluorescein dye, ranging from nausea to, rarely, death from anaphylactic shock.}

^{Anaphylaxis is a severe allergic reaction that needs to be treated right away. If you have an anaphylactic reaction, you need an epinephrine (adrenaline) shot as soon as possible, and someone should call 911 for emergency medical help. Left untreated, it can be deadly.}
Epinephrine can reverse the symptoms within minutes. If this doesn't happen, you may need a second shot within half an hour.

Central Serous Retinopathy
An association has also been made between CSC and patients with emotional distress and/or “type A” personalities. It is possible that the body produces natural corticosteroids in times of stress that may trigger CSC in an individual prone to this condition.

Patients with high blood pressure or heart disease, and those with a current or recent pregnancy have been shown to have a higher risk of developing CSC.

Treatment and prognosis

Central Serous Retinopathy, CSC is typically a self-limiting disease, and visual recovery usually occurs within a few weeks to months without treatment.
Several therapies have been used to treat chronic CSC, including thermal laser treatments, oral medications, and eye injections. A “cold laser,” called photodynamic therapy, is also effective and often used to focally treat the source of fluid leakage under the retina in chronic CSC.
