Introduction
Persisting macular holes (PMH) after surgical release of any epiretinal traction of the vitreous and adjacent membrane may rely on secondary firm adhesions between the retracted retina and adjacent retinal pigment epithelium. Secondary application of subretinal (SR)-fluid may release these adhesions followed by an anatomical closure.
Methods
Twelve surgeons applied in a consecutive case series SR-fluid in 41 eyes with PMH and reported retrospectively their initial surgical, anatomical and functional experience with this approach.
Results
The mean duration of the MH prior to SR-fluid application was 17 months (6–96 months). The mean age of the patients at the time of surgery was 72 years (54–88). The mean preoperative aperture diameter of the opening was 1212 μm (239–4344 μm), base diameter 649 μm (SD 320 μm). The mean preoperative BCVA prior to surgery was 0.1 (0.01–0.3). All patients (41/41) complained about reduced BCVA and a significant central scotoma (negative scotoma) in their central field of vision. The secondary closure rate for our PMH was 85.36% (35 out of 41 eyes) at 6 weeks after surgery. The postoperative BCVA improved to 0.22 (0.02–0.5). The application of SR-fluid was not associated with major intraoperative adverse effects.
Conclusion
Remaining SR-adhesions may inhibit PMH closure. Their release by application of SR-fluid will lead to a fast and immediate anatomical closure in many cases without serious adverse events.
