Evaluation of the Choroid,Fovea, and Retinal Nerve Fiber Layer in Patients with Rheumatoid Arthritis

Purpose: To evaluate the effect of rheumatoid arthritis (RA) on choroid, retinal nerve fiber layer (RNFL), and foveal thickness using spectral domain optical coherence tomography (OCT).

Methods: Fifty patients with RA and forty-one healthy volunteers were enrolled in this study. The subfoveal, perifoveal choroidal, RNFL, and foveal thicknesses were measured by spectral domain OCT.

Results: The mean subfoveal, nasal, and temporal choroidal thicknesses in RA individuals were significantly higher than those in the control group (p ? 0.05). However, there was no significant difference between the RA and healthy group regarding RNFL and foveal thickness (p ? 0.05). A significant correlation was found between rheumatoid factor (RF) and the subfoveal temporal choroidal thickness.

Conclusion: Choroidal thickness in RA patients was higher than that in healthy participants. Choroidal thickening showed a positive correlation with RF, which may be an indicator for systemic vasculitis.

Changes in Choroidal Thickness after Cataract Surgery

Objective: The aim of this study is to compare subfoveal choroidal thickness (SFCT) before and after uneventful phacoemulsification using enhanced depth imaging optical coherence tomography (EDI-OCT).Background: Cataract is a major cause of visual impairment in the elderly. Cataract surgery is the most common ophthalmic surgery and is performed simultaneously with glaucoma or vitreous surgery in many cases. However, according to the results in epidemiology studies, cataract surgery is associated with the onset of age-related macular degeneration (AMD) and cataract surgery increases visual acuity in these patients without an increased risk of progression to exudative AMD. Methods: A prospective study was conducted on 53 eyes of 53 patients who had phacoemulsification. Measurements of SFCT were performed preoperatively, 7 days (D7), 1 month (M1), and 3 months (M3) postoperative using the EDI-OCT technique. Central retinal thickness was also measured at the same time. Results: Twenty-seven male (50.9%) and 26 female (49.1%) with a mean age of 56.43 years ± 10.34 (SD) were analyzed. The mean choroidal thickness was 199.9 ± 60.74 µm. It significantly increased to 228.42 ± 59.77 µm at D7, then decreased to 210.78 ± 59.59 µm at M1, and then decreased to 200.63 ± 61 µm at M3. The mean retinal thickness was 260.79 ± 6.12 µm. It significantly increased to 294.09 ± 7.20 µm at D7 and then decreased to 274.70 ± 6.00 µm at M1 and 258.92 ± 5.89 µm at M3. Conclusion: Mean SFCT increased after cataract surgery. The changes in SFCT return to near the baseline after 3 months.     

Change in subfoveal choroidal thickness after argon laser panretinal photocoagulation

AIM: To evaluate changes in subfoveal choroidal thickness (SFCT) and macular thickness as measured by enhanced depth imaging spectral-domain optical coherence tomography (EDI-OCT) after argon laser panretinal photocoagulation (PRP) in patients with severe diabetic retinopathy.METHODS:This prospective, comparative case series included 21 patients (28 eyes) with severe diabetic retinopathy. All patients underwent three sessions of PRP. The SFCT and macular thickness were measured using EDI-OCT at baseline and one week after completion of 3 sessions of PRP.RESULTS:SFCT before PRP was (318.1±96.5)μm and increased to (349.9±108.3)μm (P=0.001) after PRP. Macular thickness significantly increased at one week after PRP (from 273.1±23.9μm at baseline vs 295.8±25.3μm at one week; P<0.001). No significant relationship between the changes in macular thickness and SFCT was observed (r=-0.13, P=0.52).CONCLUSION: PRP induced increases in both SFCT and macular thickness. Changes in SFCT did not correlate with changes in macular thickness.

Retinal and choroidal vascular changes in newly diagnosed celiac disease: An optical coherence tomography angiography study

Purpose:To investigate the retinal and choroidal microcirculation changes in celiac disease (CD) patients via optical coherence tomography angiography (OCT-A).Methods:This cross-sectional study included 44 pediatric patients with newly diagnosed CD and 44 healthy pediatric subjects. The vascular densities (VD) of the superficial, deep, and choriocapillar plexuses (VDs, VDd, and VDcc, respectively) (%), the superficial and deep foveal avascular zones (FAZs and FAZd) (%), the central macular thickness (CMT) (mm), and the subfoveal choroidal thickness (SFCT) (mm) were measured with swept-source OCT-A in addition to a complete ophthalmological examination.Results:Mean ages of the CD patients and the healthy participants were 12.02 ± 2.9 and 13.6 ± 2.3 years, respectively. The central sectors of the VDs and VDd measurements were found to be significantly higher in the study group compared to the control group (p = 0.006; P = 0.001, respectively), and the temporal and nasal values of the VDcc measurements were significantly lower in the study group than in the control group (p < 0.05 for both values). CMT and FAZ metrics did not differ between the groups (p > 0.05). SFCT was significantly reduced (p = 0.001), and choroidal thinning was more considerable in female CD patients (p = 0.045).Conclusion:CD seems to affect macular and choroidal microcirculation. The reduced choriocapillaris plexus parameters and choroidal thickness may provide disease activity information.

Comparison of Enhanced Depth Imaging and Swept Source Optical Coherence Tomography in Assessment of Choroidal Thickness in Vogt–Koyanagi–Harada Disease

Purpose: To compare enhanced depth imaging (EDI-OCT) and swept source optical coherence tomography (SS-OCT) in assessment of Vogt–Koyanagi–Harada (VKH) disease.

Methods: All consecutive VKH patients seen at Singapore National Eye Centre during 2012–2013 were imaged using both modalities. Subfoveal choroidal thickness (SFCT) was measured by one masked trained observer.

Results: A total of 137 pairs of scans were obtained from 48 patients. SFCT was more likely to be measurable on SS-OCT than EDI-OCT (112, 81.8%; 84, 61.3%; p<0.001 Fisher’s Exact test). There was good inter-OCT correlation of SFCT when both scans were measureable (mean of the difference in SFCT ± 2 standard deviations (SD) of –14.5 ± 21.0 μm).

Conclusions: SS-OCT images are superior to EDI-OCT but the SFCT measurements are comparable when both are readable.

METHODS: Right eyes of 24 patients with androgen deficiency and 31 healthy volunteers were included in the study. The eyes were scanned for subfoveal choroidal thickness (SFCT), choroidal vascularity index (CVI), choroid-stromal area (C-SA), choroid-luminal area (C-LA), choroid-stromal to luminal area ratio (CSLR), and the choroidal parameters within central 1500 µm of the macula (CVI1500, C-LA1500, C-SA1500, and CSLR1500) by enhanced-depth imaging optical coherence tomography (EDI-OCT) at baseline, 6th and 18th weeks of the exogenous testosterone treatment. RESULTS: The mean SFCT values of the androgen deficient groups and healthy controls were 307.7±27.0 and 303.2±37.2 µm (P=0.8). However, CVI, C-SA, CSLR, CVI1500, C-LA1500, and CSLR1500 were significantly different between the groups (all P<0.01). At the 6th week visit after exogenous testosterone treatment, SFCT, CVI, C-LA, and C-SA were significantly decreased, and these parameters returned to baseline levels at the 18th-week visit (all P>0.05). However, CVI1500 and LA1500 significantly increased at the end of the follow-up period (P<0.001). CONCLUSION: CVI is lower in androgen-deficient patients than in healthy subjects. The alterations in the choroid during the testosterone peak are transient in the treatment of patients with androgen deficiency. However, the increase in CVI within the central 1500 µm of the macula persists even after 4mo.
