Resumen
ESCALERA-ARROYO, Pedro; ARROYO-GONZALEZ, José M. y TORRES-ALARCON, Carmen G.. Changes in central choroidal thickness measured through EDI-OCT in patients on hemodialysis for the first time. Rev. mex. oftalmol [online]. 2022, vol.96, n.2, pp.47-56. Epub 02-Mayo-2022. ISSN 2604-1227. https://doi.org/10.24875/rmo.m21000213.
Purpose:
To determine changes in the foveal center choroidal thickness, 500 μm nasal and temporal to the foveal center, measured through EDI-OCT before and 1 week after patients were on hemodyalisis for the first time.
Methods:
a total of 22 eyes from 12 patients were evaluated. Patients with chronic kidney disease treated with hemodialysis for the first time, and without previous eye surgeries or procedures 6 months earlier were included. Choroidal thickness was measured at the foveal center, 500 μm nasal and temporal to the foveal center, through EDI-OCT, before and 1 week after hemodialysis treatment. Also, sociodemographic data, visual acuity, and intraocular pressure were collected. Results were assessed and analyzed using the Mann-Whitney-Wilcoxon U test.
Results:
the average choroidal thickness measured through EDI-OCT before hemodialysis treatment in the foveal center, 500 μm nasal and temporal to the foveal center, was 99.40 ± 30.80 μm, 96.77 ± 26.78 μm, and 94.00 ± 31.03 μm, respectively. One week after hemodialysis the average choroidal thickness was 89.63 ± 18.96 μm (p = 0.055), 83.18 ± 18.00 μm (p < 0.001), and 84.27 ± 27.62 μm (p = 0.002), respectively. Intraocular pressure revealed no changes 1 week after hemodialysis with levels of 13.09 ± 1.87 mmHg, and 12.77 ± 1.79 mmHg (p = 0.379), respectively.
Conclusions:
Choroidal thickness at 500 μm nasal and temporal to the foveal center decrease in patients 1 week after hemodialysis.
