Abstract
Purpose:
To assess the retinal and choroidal thickness of the macular region in patients with unilateral relentless placoid chorioretinitis (RPCR) with macular involvement
Methods:
All patients underwent a comprehensive ophthalmologic examination, best-corrected visual acuity (BCVA), axial length (AL) measurement (IOLMaster® 500; Carl Zeiss Meditec, Inc, Dublin, CA), and swept-source optical coherence tomography (DRI OCT-1; Topcon, Tokyo, Japan) in the 1050 nm wavelength. Automated segmentations of the retina and the choroid were used to obtain the corresponding thickness values
Results:
A total number of 3 patients (2 male; age range: 17-62) were included. The time from the onset of visual symptoms related to RPCR was 56, 6 and 3 months for each case. Eyes with clinically evident RPCR had a mean AL of 24.62+/-0.11 mm, whereas in the clinically healthy fellow eyes was 24.65 (p=0.70). The mean BCVA was 0.93+/-0.16 in eyes with MFC, and 1,0 in all the fellow eyes (p=0.70). The mean foveal retinal central thickness measured 257.33+/-31,53, and 269.33+/-19.75 microns respectively (p=0.99); and the mean macular retinal thickness was 288,10+/-10.22, and 300.30+/-7.17 microns respectively (p=0.20). The mean subfoveal choroidal thickness was 260.70+/-140.60, and 262.30+/-123.10 microns respectively (p=0.99); and the mean macular choroidal thickness was 248.60+/-128.40, and 255.10+/-123.60 microns respectively (p=0.99).
Conclusions:
No changes in the retinal and choroidal thickness were observed in the whole macular area of eyes diagnosed with RPCR with macular involvement compared with the asymptomatic and clinically healthy fellow eye. The role of the choroid in the pathogenesis of RPCR may be investigated in further prospective studies.
