Morphological characteristics of the optic nerve head and impacts on longitudinal change in macular choroidal thickness during myopia progression.

ABSTRACT:

Purpose

The aim of this study was to investigate the association between morphological characteristics of Bruch's membrane opening distance (BMOD), border length (BL), border tissue angle (BTA), peripapillary atrophy (PPA) as well as axial length (AL) and incident decreased macular choroidal thickness (mChT) in young healthy myopic eyes.

Methods

A total of 323 participants aged 17-30 years were included in the current 2-year longitudinal study. Each participant underwent detailed ocular examinations at baseline and follow-up. Data of AL, refraction error, PPA area, BMOD, BL, BTA and mChT were measured individually. Incident decreased mChT was defined as follow-up mChT of participants decreased into the lowest quartile of baseline mChT.

Results

Subjects with longer AL, longer BMOD were more likely to have incident decreased mChT (odds ratio [OR], 1.56; 2.09, respectively, per 1 Z-score increment), whereas larger BTA was less likely to develop decreased mChT (odds ratio [OR], 0.51, per 1 Z-score increment). The area under the receiver operating curve (AUROC) of basic risk model for incident decreased mChT was 0.6284. After adding BMOD, BTA and AL separately to the basic risk model, the AUROC of the combination could reach 0.6967, 0.6944 and 0.7383, respectively. After combining BMOD, BTA and AL to the basic model, the AUROC of the combination showed the highest AUROC of 0.7608.

Conclusions

Bruch's membrane opening distance and AL are significant risk factors for incident decreased mChT, whereas BTA played protective role in the deterioration of mChT. In addition, a combination of BMOD, BTA and AL could serve as earlier predictors of the attenuation of mChT in myopia progression.

Project description:PURPOSE:To investigate the relationship between diabetic macular edema (DME) and the choroidal layer thickness in diabetic patients. METHODS:This is a retrospective observation study. Three hundred eighteen eyes of 159 diabetes mellitus (DM) patients and age-matched 100 eyes of 79 healthy controls were enrolled. DME was defined as over 300 μm in the central retinal subfield of the Early Treatment Diabetic Retinopathy Study (ETDRS) grid sector. The central choroidal thickness (CCT), as well as inner and outer layers were determined based on enhanced depth imaging (EDI)-OCT. Diabetic patients with/without systemic diabetic treatments (DT) at the start of this study was defined as DT+ and DT-, respectively. The number of eyes examined was 62 and 256 eyes in DME+and DME-groups, respectively. DM patients were further subdivided into 4 groups with/without DME and DT; DME+DT+(35 eyes), DME-DT+(159 eyes), DME+DT-(27 eyes), and DME-DT-group (97 eyes). Multiple comparisons on CCT layers including control and each DM group were statistically examined. RESULTS:The total CCT layer was 254±83, 283±88, and 251±70 μm in the control, DME+, and DME-group, respectively. A total CCT layer in DME+was significantly thicker than the DME-group (P < 0.05). The outer CCT layer was 195±75, 222±83, and 193±63 μm in the control, DME+, and DME-group, respectively. The outer CCT layer in DME+ was significantly thicker than the DME-group (P < 0.05). In the subdivided groups, the total CCT layers in the control, DME+DT+, DME-DT+, DME+DT-and DME-DT-groups were 254±83, 274±88, 247±66, 290±84 and 258±75 μm, respectively. The outer CCT layers in each group were 195±75, 214±83, 189±58, 228±77, and 201±70 μm, respectively. Total CCT and the outer layer in DME+DT-was significantly thicker than the DME-DT+group (each P < 0.05). In contrast, there was no significant difference in inner layer between the groups. CONCLUSIONS:The total and outer CCT layers of diabetic eyes were significantly thickened in the DME+DT-as compared with the DME-DT+group, suggesting that CCT may be related to the pathology of DME.
