Purpose: To report a case of isolated foveal hypoplasia diagnosed with optical coherence tomography (OCT) in a pediatric patient.
Case summary: A 4-year-old male patient came to clinic with complaints of defective vision detected by preschool vision screening. At that initial visit, best-corrected visual acuity (BCVA) was 0.4 in the right eye and 0.6 in the left eye with bilateral hyperopia of +1.25 diopters (D) and +1.75 D in right and left eye. Fundus photograph seemed to have no abnormal findings. After prescribing glasses, he revisited the clinic 3 months later. The BCVA was still 0.3 in the right eye and 0.4 in the left eye and there was no improvement in visual acuity. To identify the cause of amblyopia, the patient underwent OCT examination. The OCT scans showed the absence of the foveal depression and persistent nerve fiber layer and inner retinal layers within the fovea in both eyes. Rechecked fundus examination revealed absent foveal reflexes and macular pigmentation in both eyes.
Conclusions: This case shows that the clinical diagnosis in children could be missed because of the subtle fundus change and OCT is useful in diagnosing isolated foveal hypoplasia.
