Purpose: To compare choroidal thickness (CT) and ocular pulse amplitude (OPA) in childhood obesity with insulin resistance (IR) and without IR. Methods: Seventy-three childhood obesity and 62 healthy children, who were both age-matched and gender-matched, comprised the study population in this prospective study. Obesity was determined as having a body mass index (BMI) – standard deviation (SD) score that was > 2 SD. Intraocular pressure (IOP) and OPA were measured using a dynamic contour tonometer. The CT measurements were performed using enhanced depth imaging optical coherence tomography at three locations, comprising at the fovea, at a position 500 µm nasal, and also at a position 500 µm temporal to the fovea. Results: Mean BMI value was 28.72 ± 4.85 in the patients with childhood obesity and 21.47 ± 1.14 in the control group. The mean IOP and OPA values were determined 15.90 ± 2.30 and 14.10 ± 2.16 mm Hg, 1.50 ± 0.28 and 1.74 ± 0.32 mm Hg in the patients with childhood obesity and the control group, respectively ( p < 0.001, p < 0.001). The mean subfoveal CT value was 350.50 ± 81.51 μm in the eyes with childhood obesity and 390.02 ± 71.50 μm in those of the control group ( p = 0.003). When the patient groups with and without IR were compared, no significant difference was found between CT, OPA and IOP values ( p > 0.005). Conclusions: Our results showed that both OPA and CT values were significantly decreased in childhood obesity patients. We suggest further studies to verify longitudinal changes in OPA and CT, as also the evaluation of these parameters in other populations.

Purpose: To compare subfoveal choroidal thickness (SFCT), retinal vessel caliber, and ocular pulse amplitude between treated polycythemia vera (PV) patients and healthy adults. Methods: Forty patients with PV and 40 age- and sex-matched healthy controls were recruited for this cross-sectional study. Spectral-domain optical coherence tomography was used for SFCT and retinal vessel caliber measurements. The Pascal dynamic contour tonometer was used for ocular pulse amplitude measurements. The correlations of blood hematocrit levels with the studied ocular parameters were analyzed. Results: There were no statistically significant differences between the PV patients and controls in SFCT, retinal vessel caliber, and ocular pulse amplitude (p > 0.05). SFCT was associated with hematocrit level in both PV patients and healthy adults (p < 0.05). Conclusions: Although SFCT, retinal vessel caliber, and ocular pulse amplitude parameters are similar in treated PV patients and healthy controls, SFCT is associated with hematocrit level.
