Purpose: To investigate the characteristics of macular pseudoholes (MPHs) with different foveal profiles and their impact on preoperative and postoperative visual acuity. Methods: A retrospective review of 47 eyes from 46 consecutive patients with MPH who had undergone vitrectomy was conducted. The MPHs were classified into u-shape and v-shape according to the morphological description of the foveola base. The best-corrected visual acuity (BCVA), central foveal point thickness, parafoveal thickness, parafoveal inner and outer retinal thickness, stretched lamellar cleavage, microcystic macular edema (MME), disorganization of retinal inner layers (DRIL), and the integrity of outer retinal layers were recorded. Results: The eyes in the v-shaped group (n=31) had lower BCVA, thicker retinal thickness, more intraretinal cleavage, MME, and DRIL than the u-shaped (n=16) group (all P＜0.05). Multiple regression analysis revealed that the morphology of the foveola base was significantly related to the preoperative BCVA (P=0.025). The VA was significantly improved in both groups, and the improvement was greater in the v-shaped group (P=0.024). No significant difference was found in the postoperative BCVA between the two groups (all P＞0.05). Conclusion: The v-shape, reflecting the stretch in the foveola, had a significant impact on preoperative BCVA. However, the VA was improved after surgery whatever their initial foveal profile.
