[Thésaurus Mesh]Choriorétinopathie séreuse centraleRésumé : SIGNIFICANCE: This is a case-control study showing changes in accommodation in eyes with acute central serous chorioretinopathy. We found that decreased accommodative amplitude in the affected eyes may indicate suppression of parasympathetic activity in those eyes as one of the pathophysiological mechanisms controlling choroidal thickness and perfusion. PURPOSE: This study aimed to evaluate the changes of accommodation in patients with acute central serous chorioretinopathy. METHODS: Patients with unilateral central serous chorioretinopathy, with and without foveal involvement, as well as patients after resolution of subretinal fluid and healthy age-matched controls were included. Accommodative amplitude was measured and compared between eyes with active or resolved central serous chorioretinopathy, fellow eyes of active central serous chorioretinopathy individuals, and eyes of controls. Correlation between accommodative amplitude and ocular and demographic parameters was calculated. RESULTS: Nineteen acute central serous chorioretinopathy patients (16 males and 3 females, 38.1 ± 5.1 years) and 17 age-matched controls (13 males and 4 females, 37.2 ± 5.4 years) were included. Accommodative amplitude in the study eyes of central serous chorioretinopathy patients was lower than that in the fellow unaffected eyes (1.25 ± 1.0 and 2.54 ± 0.94 D, respectively; P = .002) or in the eyes of healthy controls (2.41 ± 1.38 D, P = .002). In central serous chorioretinopathy eyes, after resolution of subretinal fluid or without foveal involvement, the median accommodative amplitude was lower than that in fellow eyes (1.6 [95% confidence interval, 0.83 to 1.75] and 2.7 D [95% confidence interval, 1.23 to 3.61], respectively; P = .004). No correlation was found between accommodative amplitude in affected central serous chorioretinopathy eyes and different parameters, except for age (r = −0.47, P = .04). CONCLUSIONS: Acute central serous chorioretinopathy is associated with a substantial reduction of accommodative amplitude. Note de contenu :

[Thésaurus HELB]:Optique:Épaisseur choroïdienne fovéolaireRésumé : SIGNIFICANCE: This is a proof-of-concept study showing the possibility of pharmacological control for choroidal thickness using pilocarpine as an agent that causes 2 to 5% choroidal thinning in healthy eyes after the instillation. PURPOSE: The purpose of this article was to study the effect of instillation of 1% pilocarpine on choroidal thickness in healthy subjects. METHODS: Sixteen healthy individuals (seven males and nine females; mean ± standard deviation age, 25.8 ± 3.3 years) were included. All participants received optical coherence tomography to evaluate subfoveal choroidal thickness (SCT) and choroidal area on cross-sectional scan within 4-mm central area. Axial length was measured using optical biometry. Optical coherence tomography was performed before and after pilocarpine was instilled six times for a 75-minute period in one eye; the fellow eye was used as the control. Subfoveal choroidal thickness and choroidal area were measured by two masked graders in random fashion and averaged for analysis. RESULTS: After instillation of 1% pilocarpine, percentage SCT change in study and control eye was −3.3 ± 3.8% and 0.4 ± 3.2%, respectively (P = .03). Percentage change choroidal area in study and control eye was −2.3 ± 2.5% and 0.8 ± 3.3%, respectively (P < .001). There was a correlation between percentage SCT change and axial length (r = −0.56, P < .001), as well as between percentage SCT change and baseline SCT (r = 0.72, P < .001). CONCLUSIONS: Instillation of 1% pilocarpine causes a decrease of choroidal thickness, which is more substantial in eyes with short axial length and thick choroid.
