Purpose: To describe the presence of specific morphological characteristics of idiopathic, full-thickness macular hole (MH) potentially influencing postoperative best corrected visual acuity (BCVA) and surgical outcomes.
Design: Retrospective, multicenter and interventional case series.
Methods: Clinical charts and multimodal imaging pictures of 149 eyes of 143 consecutive patients diagnosed with MH, treated surgically and with a minimum follow-up of 12 months, were reviewed.
Results: Supra-retinal pigment epithelium (RPE) granular deposits were diagnosed in 121 of 149 eyes (81.2%). A smooth morphology was identified in 58 of 149 eyes (38.9%), whereas a bumpy border was present 91 of 149 eyes (61.1%). Photoreceptor disruption was mainly located close to the MH aperture. In 8% of the included cases, preoperative anatomical progression from smooth to bumpy morphology was noted. The presence of supra-RPE granular deposits was a significant predictor of lower postoperative BCVA only in univariate analysis (P < .001). The presence of a bumpy border was significantly correlated with lower postoperative BCVA in both univariate and multivariate analysis (P < .001). BCVA gain was significantly lower in MH with bumpy borders (P < .001). A bumpy border was also significantly associated with poor postoperative anatomical restoration (P < .001).
Conclusions: Supra RPE-granular deposits and a bumpy morphology may be indicators of photoreceptor disruption in MH. A bumpy morphology may suggest deeper and potentially irreversible photoreceptor damage, and may negatively influence both functional and anatomical recovery.
