목적 : To evaluate the characteristic clinical features of posterior microphthalmos
방법 : Medical records of four patients (8 eyes) between the ages of 3 and 31 years with posterior microphthalmos were reviewed. Thorough ocular examinations were performed, including visual acuity, intraocular pressure, ocular alignment, axial length, cycloplegic refractive measurement, slit lamp biomicroscopy of the anterior segment and fundus, and spectral-domain optical coherent tomography (SD-OCT).
결과 : All subjects had presented with high hyperopia (+11.0–+15.75 D) and retinal papillomacular folds in both eyes. They also had reduced bilateral axial length (15.55–18.61 mm), with foreshortening of the posterior segment and a relatively normal anterior segment. Papillomacular retinal folds involving the inner retinal layers and sparing the outer retinal layers, along with the absence of foveal depression, were confirmed by macular SD-OCT. In 3 patients, we found esodeviation associated with posterior microphthalmos, and 1 of these required strabismus surgery.
결론 : Posterior microphthalmos is a developmental arrest of ocular growth. In addition to high hyperopia and retinal papillomacular folds, various types of esotropia, optic disc hypoplasia, and neurosensory retinal detachment may accompany posterior microphthalmos. In particular, children with posterior microphthalmos require early appropriate management of the high refractive error and resultant esotropia.
