Recent technological advances have led to an improved understanding of central serous chorioretinopathy (CSC): new pathophysiological insights, new imaging techniques for diagnosis and management, and new treatments. The primary role of the choroid has become more widely accepted with widespread use of indocyanine green angiography. Optical coherence tomography (OCT), and particularly enhanced depth imaging OCT, demonstrate a thickened and engorged choroid. Adaptive optics, fundus autofluorescence, multifocal electroretinography, microperimetry, and contrast sensitivity testing reveal that patients with even a mild course suffer previously undetected anatomic and functional loss. While focal laser and photodynamic therapy are the current standard of care for persistent subretinal fluid in CSC, they are not appropriate in all cases, and the optimal timing of intervention remains unclear.

There were no apparent short-term safety concerns for intravitreal bevacizumab injection for CNV. Treated eyes had a significant decrease in macular thickness and improvement in visual acuity. The follow-up was too short to make any specific treatment recommendations, but the favorable short-term results suggest further study is needed.

Initial treatment results of patients with macular edema secondary to CRVO did not reveal any short-term safety concerns. Intravitreal bevacizumab resulted in a significant decrease in macular edema and improvement in visual acuity. The number of patients in this pilot study was limited and the follow-up is too short to make any specific treatment recommendations, but the favorable short-term results suggest further study is needed.
