Clinical Characteristics and Outcomes of Pediatric Macular Hole: A Retrospective Case Series Study

Purpose: To evaluate the clinical characteristics, etiologies, and treatment outcomes of pediatric macular holes (MHs).Methods: The medical records of pediatric patients under 18 years of age diagnosed with MHs at Severance Hospital between January 2005 and December 2022 were retrospectively reviewed. Data regarding etiology, MH diameter, treatment methods, and both visual and anatomical outcomes were analyzed.Results: Among 15 patients (16 eyes), traumatic MHs were identified in 7 cases (46.7%), while non-traumatic causes included Stargardt disease, familial exudative vitreoretinopathy, and vitreomacular traction. No statistically significant differences were observed between the traumatic and non-traumatic groups in terms of age, MH diameter, or initial and final best-corrected visual acuity (BCVA). However, there was a significant difference in sex distribution, with all traumatic cases occurring in males, whereas only 3 of the 9 non-traumatic eyes were male (p = 0.01). Surgical intervention was performed in 13 eyes, achieving anatomical closure in 62.5% (10 eyes). The three eyes without closure (37.5%) were all non-traumatic cases. BCVA (logMAR) significantly improved from a median of 1.00 preoperatively to 0.70 postoperatively (p = 0.013). Among the three eyes that did not undergo surgery, one demonstrated spontaneous closure, and another achieved closure following medical treatment.Conclusions: Pediatric MHs may arise from various ocular conditions beyond trauma. Surgical intervention was effective, particularly for traumatic MHs, while non-traumatic cases demonstrated a lower closure rate. In some instances, spontaneous or medically induced closure occurred without surgical management. Further multicenter studies with larger cohorts are warranted to establish definitive management guidelines for pediatric MHs.
