Macular Structures, Optical Components, and Visual Acuity in Preschool Children after Intravitreal Bevacizumab or Laser Treatment

PURPOSE: To investigate the macular structures, optical components, and visual acuity in preschool-aged children with a history of type I retinopathy of prematurity who underwent either intravitreal bevacizumab (IVB), laser, or a combination of treatments. DESIGN: Comparative interventional case series. METHODS: Setting: A referred medical center in Taiwan. Study Population: Eighty eyes from 42 patients (33 IVB-treated eyes from 17 children, 24 laser-treated eyes from 13 children, and 23 laser + IVB-treated eyes from 12 children). Observation Procedure: Spectral domain optical coherence tomography. Main Outcome Measures: The retinal thickness in the foveal area and the associated morphologic changes in foveal depression. RESULTS: Compared with the laser-treated and laser + IVB-treated eyes, the IVB-treated eyes had less myopia and deeper anterior chamber depths but presented similar axial lengths and corneal curvatures (P=.001, P=.002, P=.95, and P=.16, respectively). The IVB-treated eyes had significantly thinner foveal, parafoveal, and perifoveal retinal thicknesses (P<.01 for all) and a higher incidence of foveal depression than the laser or laser + IVB-treated eyes. The macular and subfoveal choroidal thicknesses did not differ among the groups (P=.21 and P=.63, respectively). Moreover, compared with the eyes treated with laser or laser + IVB, the IVB-treated eyes had better uncorrected visual acuity, although a significant difference was not observed in best-corrected visual acuity (P=.008 and P=.29, respectively). CONCLUSIONS: Compared with laser therapy, IVB-treated eyes were associated with deeper anterior chamber depths and thinner foveal, parafoveal, and perifoveal thicknesses. Moreover, these IVB-treated eyes had fewer refractive errors and better uncorrected visual acuity. (C) 2018 Elsevier Inc. All rights reserved.
