Dear Editor,

Idiopathic central serous chorioretinopathy (CSCR) usually affects middle-aged men and is characterized by a serous neurosensory retinal detachment in the macular region. Visual disturbances are usually mild and spontaneous recovery occurs over a few months. Some eyes with CSCR may however have a poor visual outcome due to retinal pigment epithelium atrophy, persistent pigment epithelial detachment, subretinal fluid, recurrences, and submacular choroidal neovascularization (CNV). [1] Probable reasons for development of CNV following CSCR are decompensation of the pigment epithelium/Bruch's membrane complex by disease process itself, or puncture of Bruch's membrane by laser burns used to treat the disease. [2]

The reported treatment options for CNV secondary to CSCR are laser photocoagulation, photodynamic therapy (PDT) [3]

and transpupillary thermotherapy (TTT). As intravitreal bevacizumab (IVBe) has shown encouraging results in CNV from different etiologies, we tried it as a treatment for CNV secondary to CSCR in the patient described herein.

A 36-year-old man presented with sudden blurring of vision in the right eye (RE). Patient also revealed that he had suffered from a similar episode nine months earlier from which he had recovered spontaneously. At presentation he had a best corrected vision acuity (BCVA) of 20/200 RE and 20/20 in left eye (LE). Fundus examination indicated the presence of CSCR and subfoveal CNV in the RE. Existence of both pathologies concurrently were confirmed on fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) [Stratus OCT]. FFA demonstrated subfoveal early hyperfluorescence with increasing leakage in the late phase suggestive of CNV. It also showed an ink-blot hyper-fluorescence superior to the fovea gradually increasing in size and intensity [Figure 1] indicative of active CSCR. OCT revealed subfoveal CNV, subretinal fluid and cystoid retinal edema [Figure 2].{Figure 1}{Figure 2}

After obtaining informed consent, off-label IVBe (1.25 mg/0.05 ml) was administered. One month after injection repeat FFA showed absence of ink-blot leakage and decreased leakage from CNV. OCT demonstrated resolution of both subretinal fluid and cystoid edema [Figure 2]. His BCVA improved to 20/25 RE at one month and was maintained till one year follow-up. No recurrence in CSCR or CNV was seen.

It is well recognized that CNV requires mediators of angiogenesis. The most widely studied mediator has been vascular endothelial growth factor (VEGF), which plays a central role in the complex cascade of vessel growth, proliferation, and hyper-permeability. Intravitreal injections of bevacizumab, a humanized anti-VEGF antibody which inhibits VEGF-A protein has been reported to produce favorable results in CNV from various etiologies. Our patient had active CSCR along with classic subfoveal CNV. The role of VEGF and anti-VEGF agents in CSCR has not been studied widely. Some reports suggest favorable results of bevacizumab in CSCR. [4],[5] In our case we found prompt resolution of ink-blot leak and CNV exudation.

In conclusion, the anatomic and visual result in the eye with CNV associated with active CSCR after IVBe is encouraging. Further studies are required to confirm the efficacy and safety of bevacizumab in the management of concurrent CSCR and CNV.
