Choroidal Thickness in Central Serous Chorioretinopathy

Abstract

The choroid is diffusely thickened in CSC likely because of the choroidal vascular dilatation. The nasal macula undergoes the greatest alterations in choroidal thickness compared with the other areas.

Comparison of subfoveal choroidal thickness in healthy pregnancy and pre-eclampsia

“…In addition, this finding implies a correlation between the occurrence of CSC in pregnant women and increased CT in pre-eclamptic patients, because increased choroidal hydrostatic pressure contributes to CSC occurrence, and choroidal delayed filling in CSC was reported previously. 6,10,23 In this study, a small amount of subretinal fluid was seen in one patient with pre-eclampsia, but it was absorbed after delivery. Note that the systemic hypertension in this patient was controlled 5 days before the ophthalmic examination, and the CT decreased with the disappearance of the subretinal fluid ( Figure 2).…”

“…[9][10][11] Choroidal thickening was observed in eyes with CSC or polypoidal choroidal vasculopathy and choroidal atrophy was also noted in eyes with age-related macular degeneration. 6,12,13 An association between choroidal thickening and choroidal vascular hyperpermeability was reported in previous studies.…”

“…6,12,13 An association between choroidal thickening and choroidal vascular hyperpermeability was reported in previous studies. 10,14 The cause of CSC development in pregnant women is not fully understood, and angiographic study is limited with respect to possible transplacental transport or lactation. Enhanced-depth imaging optical coherence tomography enables non-invasive and non-toxic assessment of choroidal vasculature.…”

Does choroidal thickness change with fluorescein or indocyanine retinal angiography procedures?

“…Subfoveal CT is reported to increase in some diseases, such as polypoidal choroidal vasculopathy (11) and central serous chorioretinopathy (22), yet in contrast is reported to decrease in retinal angiomatous proliferation (23). If a physician thinks that a patient may have such a disease, extra care must be taken while evaluating the patient's CT.…”

Choroidal Thickness in Both Eyes of Patients with Unilateral Central Serous Chorioretinopathy

“…The study reported new leakages sites in normal eye of CSCR patients when follow up was done for 2 years [7]. Reports [6,19] on Indocyanine green angiography (ICGA) in CSCR revealed instability of choroidal circulation. These studies suggested that increase in choroidal vascular hyperpermeability might be the root cause of CSCR.…”
