Abstract
Purpose
To investigate subclinical choroidal and retinal changes in recently diagnosed pediatric hypertension (HT) patients.
Methods
This prospective case–control study consisted of 62 treatment naive HT patients (34 essential HT and 28 renal-induced HT) and 62 control subjects aged 10–16 years. All demographic data and ocular parameters were noted. Macula and choroid measurements were acquired by spectral domain optical coherence tomography (SD-OCT). Choroidal measurements were obtained by taking the mean of the measurements taken from 3 nasal and 3 temporal locations at 500µ intervals (mean nasal, mean temporal) in addition to the subfoveal area.
Results
All choroidal thickness (ChT) values in HT subjects were significantly lower than in the healthy group (p < 0.001 for all). Also, there was no statistically significant difference between central macular thickness (CMT) and mean macular thickness (MMT) between the two groups. Subfoveal ChT, mean ChT, and CMT values were statistically lower in patients with renal-induced HT compared to essential HT subjects (p < 0.001, p = 0.04, p = 0.014, respectively). No significant correlation was observed between choroidal thicknesses and blood pressure values in essential and renal HT groups except weak correlation between mean temporal ChT and systolic blood pressure (SBP) in renal HT group (r = − 0.464, p = 0.013).
Conclusion
This study demonstrated that choroidal thickness decreased even during the subclinical period in treatment naive pediatric HT subjects. In addition, it has been shown that the choroid is more affected in renal-induced HT compared to essential HT group.
