Abstract Details

PURPOSE:Enhanced depth imaging (EDI) optical coherence tomography (OCT) provides high-definition cross-sectional images of the choroid. Information on alterations in choroidal thickness (CT) after Laserphotocoagulation (LC) in AP-ROP and Threshold Disease (TD) are rare.


Potential risk factors (gestational age (GA), birth weight (BW), SE, AXL and SFCT) influencing visual acuity were evaluated by using multivariate linear regression analysis.


75 eyes were retrospectively analyzed in 4 groups. In group-1 and -2 patients with AP-ROP and TD, respectively, who underwent LC were included. Group-3 include ROP children without LC. Group-4 include full-term children. Infants aged ≥4<7, who had examination of subfoveal (SF) CT with SD-EDI-OCT, visual acuity (VA), spherical equivalent (SE), anterior segment and fundus examination, axial lenght (AXL) were included. In AP-ROP and TD-Group, CT after LC was evaluated with EDI-OCT concerning differences comparing with group-3 and -4.


BW, GA were significantly different between the groups. SE and visual acuity were not significantly different between group-3 and -4. AXL and SFCT were not significantly different between group-2 and -3 and between group-3 and -4, respectively. Multivariate linear regression analysis revealed SFCT for group-1 and -2, GA for group-3, and GA, SFCT and AXL for group-4 as independent risk factor influencing visual acuity.


In the applied model SFCT is significant independent risk factor influencing visual acuity in laserphotocoagulated groups.
