“…Bourke et al reported a correlation between untreated systemic hypertension and choroidopathy (29) . The reduction of CT has been reported in a study with smokers, which was thought to be due to increased resistance in the retinal vasculature (30) . Similarly, we observed that the subfoveal, temporal, and nasal CT measurements at 500 µm, 1000 µm, and 1500 µm were significantly lower in migraine patients compared with those in controls (p<0.01).…”

Espessuras da camada de fibras nervosas retinianas, complexo de células ganglionares e coroide na enxaqueca ABSTRACTPurpose: To evaluate the thicknesses of the peripapillary retinal nerve fiber layer (RNFL), ganglion cell complex (GCL), and choroid layer using spectral domain optical coherence tomography (SD-OCT) for investigating the effects of vascular changes on the eye and optic nerve in patients who have migraine with aura. Methods: Forty-five patients who had migraine with aura (migraine group) and 45 healthy individuals (control group) were enrolled in the study. Age, gender, duration after migraine diagnosis, intraocular pressure, and axial length measurements were recorded in each case. RNFL, GCL, and choroid layer thicknesses were measured using SD-OCT in all participants. Results: The mean age was 36.1 ± 6.7 (20-45) years in the migraine group and 35.7 ± 8.6 (19-45) years in the control group. There was no significant difference in the RNFL thicknesses of the temporal and nasal quadrants (p>0.05). The RNFL thicknesses of the superior and inferior quadrants were significantly lower in the migraine group compared with those in the control group (p=0.001, p<0.01, respectively). Measurements for the superior and inferior GCL were not significantly different between the groups (p>0.05). Subfoveal, temporal, and nasal choroidal thickness measurements at 500 µm, 1000 µm, and 1500 µm were significantly lower in the migraine group than in the control group (p=0.001; p<0.01, respectively). Conclusions:Compared with the controls, the RNFL and choroid layer were determined to be thinner in patients who had chronic migraine with aura. de 36,1 ± 6,7 (20-45) anos no grupo enxaqueca e 35,7 ± 8,6 (19-45) Keywords

Choroidal thickness in relation to sex, age, refractive error, and axial length in healthy Turkish subjects

The aim of this study was to investigate the association between choroidal thickness (CT) and sex, age, refractive error (RE), and axial length in healthy subjects. This is a study of 154 eyes in 154 healthy subjects. CT measurements were performed by the same experienced technician using a spectral domain optical coherence tomography device. CT was measured perpendicularly from the outer edge of the retinal pigment epithelium to the choroid-sclera boundary at the fovea and at six more points which are located at, respectively, 500 µm nasal to the fovea, 1,000 µm nasal to the fovea, and 1,500 μm nasal to the fovea, 500 μm temporal to the fovea, 1,000 μm temporal to the fovea, and 1,500 μm temporal to the fovea. The RE was measured by autorefractometry, and the axial length was measured by interferometry. Statistical analysis was performed to evaluate CT at each location, and to the correlations of CT with sex, age, RE, and axial length. The mean subfoveal CT was 265.86 ± 60.32 µm, the mean age was 49.01 ± 19.19 years, the mean RE was -0.17 ± 1.20 diopters (D), and the mean axial length was 23.39 ± 0.76 mm. CT profile indicated that the choroid was thicker at the fovea than at temporal and nasal locations. Univariable linear regression analysis showed that subfoveal CT decreased 3.14 µm for each year of age and decreased 79.33 µm for each mm of axial length (P = 0.000, R(2) = 0.249; P = 0.000, R(2) = 0.487, respectively). In a similar analysis, subfoveal CT was found to decrease by 50.24 µm/D myopia-shifted change in refraction (P = 0.000, R (2) = 0.201). The subfoveal choroid was 99.16 µm (39.22 %) thicker in men than women when adjusting for age and axial length (P = 0.000, R(2) = 0.249). CT decreases with increasing myopia, age, and axial length. Men had thicker choroid than women, and CT varies depending on location.

G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Bu prospektif çalışmaya, 32 PAAG hastasının 32 gözü, 32 PEX glokom hastasının 32 gözü, yaş ve cinsiyet olarak eşleştirilmiş sağlıklı 32 bireyin 32 gözü dâhil edildi. Gruplarda rutin oftalmolojik muayenenin ardından koroid kalınlığı "Spectral Domain Optik Koherens" tomografi cihazı kullanılarak ölçüldü. Koroid kalınlıkları makuler alanda subfoveal, 1.500-3.000 µm nazal, 1.500-3.000 µm temporal kadranda ölçüldü. Peripapiller alanda ise üst, alt, nazal ve temporal kadranda koroid kalınlığı değerlendirildi. B Bu ul lg gu ul la ar r: : Gruplar arasında ortalama yaş, cinsiyet ve aksiyel uzunluk açısından anlamlı bir fark yoktu (hepsi için, p>0,05). PEX glokom hastalarında makuler ve peripapiller (alt kadran hariç) alanda ortalama koroid kalınlığı PAAG ve kontrol grubuna göre daha ince bulundu (hepsi için, p<0,05). PAAG grubunda makuler ve peripapiller ortalama koroid kalınlığı açısından kontrol grubuyla anlamlı bir fark saptanmadı (hepsi için, p>0,05). S So on nu uç ç: : Sağlıklı bireylere kıyasla PAAG'li hastalardaki koroid kalınlığı benzer, PEX glokomlu hastalardaki koroid kalınlığı ise düşük bulunmuştur.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Glokom, açık açılı; koroid A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : To compare the macular and peripapillary choroidal thickness in patients with primary open angle glaucoma (POAG), pseudoexfoliation (PEX) glaucoma and healty controls. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : In this prospective study, 32 eyes of 32 POAG patients, 32 eyes of 32 PEX glaucoma patients and 32 eyes of 32 age and sex matched healthy subjects were enrolled. After routine ophthalmological examination, choroidal thickness assessment was performed by spectral domain optical coherence tomography for all groups. Choroidal thickness was measured subfoveal at macular area, nasal 1.500-3.000 µm, 1.500-3.000 µm temporal quadrants. At peripapillary area, the choroidal thickness has been measured at upper, lower, nasal and temporal quadrants. R Re es su ul lt ts s: : There was not a significant difference in terms of mean age, sex and axial length between all groups (all, p>0.05). In PEX glaucoma patients, mean choroidal thickness at macular and peripapillary areas (except lower quadrant) was lower compared to PAAG and control groups (all p<0.05). In PAAG group, there was not a significant difference for mean macular and peripapillary choroidal thickness compared with control group (all, p>0.05)...

Effect of Smoking on Choroidal Thickness in Healthy Smokers

Abstract: Smoking caused acute, significant increase in choroidal thickness that returned to baseline levels after 1 h. The choroidal and retinal thicknesses did not differ significantly between the healthy young smokers and non-smokers.
