Abstract:
Objective:To comparatively observe optical coherence tomography (OCT) image features between traumatic macular hole (TMH) and idiopathic macular hole (IMH).Methods:A retrospective clinical study. A total of 174 patients (174 eyes) with macular hole (MH) diagnosed at Shantou International Eye Center from December 2008 to May 2024 were included in the study. Among them, there were 75 patients (75 eyes) with TMH and 99 patients (99 eyes) with IMH, and they were divided into the TMH group and the IMH group accordingly. All the affected eyes underwent best corrected visual acuity (BCVA) and OCT examinations. The BCVA was examined using a standard logarithmic visual acuity chart, and was converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity for statistical analysis. The minimum diameter and basal diameter of the MH, as well as the average, nasal, superior, inferior, and temporal center retinal thickness (CRT) around the MH were measured by OCT. The independent-sample t test was used to compare the logMAR BCVA, hole diameter, and CRT at the hole margin between the groups. Results:There were significant differences in age ( t=-15.857) and gender ratio ( χ2=28.154) between the TMH group and the IMH group ( P<0.05), while there was no significant difference in logMAR BCVA ( t=1.962, P>0.05). The minimum diameter of the hole in the TMH group was smaller than that in the IMH group, but the basal diameter was larger, with significant differences ( t=-3.322, 2.570; P<0.05). The thickness of the neuroepithelial layer at the hole margin in the TMH group was thinner than that in the IMH group, with significant differences in the superior ( t=-2.747), inferior ( t=-2.316), and nasal ( t=-2.851) regions ( P<0.05), and no significant difference in the temporal region ( t=-1.586, P>0.05). In the TMH group, the number of eyes with macular cystoid edema (CME), posterior vitreous detachment (PVD), retinal atrophy, subretinal hemorrhage, choroidal laceration, and focal neuroepithelial detachment was 36 (48.00%, 36/75), 4 (5.33%, 4/75), 4 (5.33%, 4/75), 15 (20.00%, 15/75), 8 (10.67%, 8/75), and 19 (25.33%, 19/75) eyes, respectively. In the IMH group, the number of eyes with CME and PVD was 95 (95.96%, 95/99) and 94 (94.95%, 94/99) eyes, respectively. Conclusion:Compared with IMH, TMH has a larger basal diameter, a thinner CRT at the hole margin, a lower incidence of CME and PVD, and a higher incidence of subretinal hemorrhage, focal neuroepithelial detachment, choroidal laceration, and retinal atrophy.
