Purpose: To describe morphological features of traumatic macular holes (TMH) on optical coherence tomography (OCT) and to correlate them with clinical findings. Methods: Seventy-three consecutive patients diagnosed with full-thickness TMH involving the fovea underwent complete ophthalmic evaluation followed by horizontal and vertical line scans using the StratusOCT. Retinal thickness at the edges of the holes, apical and basal diameters, and various clinical parameters were recorded. The approximate apical and basal areas and eccentricities of the holes were calculated. Morphological parameters were correlated with clinical findings. Results: Based on OCT findings, TMHs were classified into 5 morphological types with varying average retinal thicknesses, apical areas, and basal areas. Patients who presented more than 90 days after injury had greater average retinal thickness (p=0.03) and apex areas (p=0.002) compared to those who presented within 90 days. Older patients developed more circular holes, i.e. less eccentricity of the apex (p=0.04) and base (p=0.01). Interestingly, none of the morphological parameters investigated in the current study correlated with visual acuity. Patients who presented later in the clinical course or who had greater average retinal thicknesses tended to have better vision (p=0.11 and p=0.07, respectively). Conclusions: OCT evaluation may yield important insights into the pathogenesis and clinical findings of traumatic macular holes.
