Primary full-thickness macular holes (FTMHs) are one of the causes of persistent visual acuity reduction. Currently, higher demands are placed on the anatomical and functional outcomes of treatment for this pathology, which has stimulated the development and improvement of surgical techniques.
PURPOSE
This study aimed to evaluate the clinical effectiveness of the developed surgical technique for primary small- and medium-sized FTMHs that preserves the intact internal limiting membrane (ILM) of the retina in the papillomacular bundle (PMB) area of the nerve fibers (keyhole technique).
MATERIAL AND METHODS
The study included 72 patients who underwent surgery for retinal FTMH between 2021 and 2023. The subjects were divided into two groups: the main group (41 patients) and the control group (31 patients). In all cases, a standard three-port vitrectomy was performed. ILM peeling was carried out through sequential, targeted removal of its local areas concentrically to the macular hole. In the main group, the ILM in the projection of the PMB was preserved intact, in contrast to the surgical technique used in the control group. The follow-up period lasted up to 12 months after surgery.
RESULTS
Anatomical closure of the FTMH was achieved in all patients. The main group demonstrated a more pronounced positive dynamic across all functional parameters compared to the control group. Intergroup differences were statistically significant (except for visual acuity), indicating significantly more favorable therapeutic outcomes in the main group.
CONCLUSION
The proposed surgical technique for primary FTMHs with a minimal diameter of no more than 400 μm with preservation of the intact papillomacular area of the retina provides better anatomical and functional outcomes in comparison with the method that involves peeling of the ILM around the macular hole in a concentric pattern.
