“…In the eye, choroidal thickness may be affected by several factors, such as age, axial length, and refractive errors [ 12 , 13 ]. A number of studies have found that choroidal thickness plays a prognostic or predictive role in various local (e.g., diabetic retinopathy), and systemic diseases (e.g., hypertension, anemia, rheumatoid arthritis and obesity) [ 14 – 20 ].…”

“…Many authors have reported that the reasons for the differences in the choroidal thickness results between studies are different software programs for measurement, differences in the light source of the OCT, ethnic differences, differences in the age, refraction defects and axial length in the patient profile [ 14 – 20 ]. However, since a comparison was made with the control group, and the characteristics of the patient and control group were similar, the findings suggest that comparison of the measurements resulted in useful data.…”

Decreased choroidal thickness in vitiligo patients

BackgroundVitiligo is a disease characterized by depigmented macules and patches that occur as a result of the loss of functional melanocytes from the affected skin through a mechanism which has not been elucidated yet. Destruction of pigment cells in vitiligo may not remain limited to the skin; the eyelashes, iris, ciliary body, choroid, retinal pigment epithelium and meninges may also be affected. This study aims to compare the choroidal thickness of patients with and without vitiligo using optical coherence tomography (OCT).MethodsSpectral-domain optical coherence tomography (SD-OCT) (Retina Scan Advanced RS-3000 NIDEK, Japan) instrument (with λ = 840 nm, 27,000 A-scans/second and 5 μm axial resolution) was used for the imaging. Statistical analysis was performed using SPSS 21.0 software package.ResultsIn all values except optic nevre area measurements, the choroidal thickness of all vitiligo patients was found out to be thinner compared to the control group.ConclusionsIn vitiligo, the choroidal thickness may be affected by the loss of melanocytes.

“…However, a previously observed inverse correlation between age and CT might have affected this correlation [ 25 ]. A number of studies have found that CT plays a prognostic or predictive role in various local (for example, diabetic retinopathy, and AMD), and systemic diseases (for example, hypertension, anemia, and rheumatoid arthritis) [ 24 , 26 – 33 ].…”

BackgroundExcessive weight is a well-known risk factor for microvascular diseases. Changes in thickness in a vascular tissue, such as the choroid, can be useful to evaluate the effect of obesity on the microvascular system. The aim of this study was to evaluate the choroidal thickness (CT) changes in obese women, using optical coherence tomography (OCT).MethodsThe prospective clinical study included examination of the right eyes of 72 patients. The right eyes of 68 patients were examined and served as the controls. A complete ophthalmological examination and OCT imaging were performed for each group studied. The CT in each eye was measured using OCT.ResultsThe obese group consisted of 72 female patients with a mean age of 37.27 ± 1.18 years. The control group included 68 female subjects with a mean age of 37.85 ± 7.98 years (p > 0.05). There was no statistical significant difference for the foveal retinal thickness measurements between the two groups (p > 0.5). Our study revealed significant choroidal tissue thickening subfoveally and at areas 500 μm temporal, 500 μm nasal, and 1500 μm nasal to the fovea in the obese group (all p < 0.05). There was a positive correlation between body mass index (BMI) and CT changes.ConclusionsCT may increase in obese women and a positive correlation was found between BMI and CT.The trial protocol was approved by the Local Ethical Committee of the Kırıkkale University, date of registration: April 27, 2015 (registration number: 10/11).

“…Karaca et al collected choroidal measurements at three points in their study of patients with obstructive sleep apnea syndrome and found no significant differences relative to control group measurements [ 6 ]. Pekel et al evaluated choroidal changes in patients who had undergone cardiopulmonary bypass and also failed to detect any significant changes [ 4 ]. In addition, Ngo et al presented a case report of high altitude-induced retinopathy in a patient with significantly increased CT [ 23 ].…”

Changes in the choroidal thickness in reproductive-aged women with iron-deficiency anemia

BackgroundThe aim of this study was to investigate the potential significance of the central macular thickness (foveal thickness-FT) and choroidal thickness (CT) in the eyes of patients with iron-deficiency anemia, the most common form of the anemia, via enhanced-depth imaging optical coherence tomography (EDI-OCT). We also investigated whether such changes might serve as an early indicator of underlying hematological disease.MethodsThis prospective clinical study compared 96 female patients with iron-deficiency anemia and 60 healthy female control subjects. The macular and choroidal thicknesses in the temporal and nasal subfoveal areas were measured using enhanced-depth imaging optical coherence tomography (EDI-OCT) at 500 and 1500 microns and in five different regions (FCT, T1500, T500, N500, and N1500).ResultsThe mean ages of the patients and healthy controls were 34.08 ± 10.39 years and 32.29 ± 8.28 years, respectively (P =0.232). There were no significant changes in macular thickness between the groups (225.58 ± 19.76 vs. 222.45 ± 13.51, P =0.2). The choroidal thickness was significantly reduced in the patient group relative to the controls at all measured points (foveal choroidal thickness, P = 0.042; nasal–500 microns, P = 0.033; temporal–500 microns, P = 0.033; and temporal–1500 microns, P = 0.019). At some points, the choroidal thickness findings correlated with the hemoglobin values (temporal–500 microns, r = −0.287, P = 0.001; nasal–500 microns, r = −0.287, P = 0.005; nasal–1500 microns, r = −0.245, P = 0.016; and temporal–1500 microns, r = −0.280, P = 0.06).ConclusionsPatients with iron-deficiency anemia had a significantly reduced choroidal thickness.
