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.

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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