Peripapillary Choroidal Thickness

Purpose. To investigate the potential relationship between open-angle glaucoma (OAG) and peripapillary choroidal thickness (PPCT).Materials and Methods. Relevant publications were searched systematically through various databases from inception to January 2016. Studies comparing PPCT in OAG patients and healthy controls were retrieved. All qualified articles were analyzed using Stata 14.0 and Revman 5.3 software.Results. A total of 13 studies were identified for inclusion. There was a significant reduction of average PPCT in OAG patients compared to control participants (WMD = −24.07, 95% CI: −34.29, −13.85). Reduction of PPCT was significant in the superior (WMD = −28.87, 95% CI: −44.96, −12.78) and nasal (WMD = −21.75, 95% CI: −41.52, −1.98) sectors, but there was no significant reduction of PPCT in the inferior (WMD = −9.57, 95% CI: −36.55, 17.40) and temporal (WMD = −13.85, 95% CI: −35.40, 7.70) sectors. No obvious publication bias was detected.Conclusions. This meta-analysis suggests that open-angle glaucoma patients have significantly decreased peripapillary choroidal thickness compared to healthy individuals. Peripapillary choroidal thickness measured by optical coherence tomography may be an important parameter to consider in open-angle glaucoma.

Objective: The main reason for complications in congenital heart diseases (CHD) is decreased blood oxygen saturation and polycythemia which are typical for cyanosis. These parameters may promote the damage of the retina because haemodynamic regulation is essential for the structural and functional integrity of the macular subfields. The aim of this study was to evaluate choroidal thickness (CT) measurements in children with CHD using spectral domain optical coherence tomography (OCT). Methods: This prospective study compared 30 CHD and 30 healthy control children. CT was examined with spectralis spectral-domain OCT (Retinascan RS-3000; Nidek). CT was obtained at the subfovea, 500 μm and 1000 μm nasal to the fovea (N500, N1000) and 500 μm and 1000 μm temporal to the fovea (T500, T1000). Only the right eye values were used for statistical comparisons between the groups. The domain cardiac lesions were divided physiologically into two categories: volume overload and cyanotic. Results: Mean age was 11.0±3.5 years in CHD childrens and 10.9±3.6 years in the control group (p=0.971). Children with CHD had no statistically significant CT measurements compared with healthy controls (p>0.05). Conclusion: Although in high haematocrit, low oxygen saturation or the presence of the volume overload in the history of CHD patients, our data suggests that patients with CHD show normal CT. The reason may be medical and surgical treatment of hypoxia, erythrocytosis and volume overload in CHD patients.
