OBJECTIVE: To evaluate the long-term results of gas tamponade without vitrectomy in patients with myopic foveoschisis (FS) and foveal detachment (FD).
METHODS: Twenty eyes of 20 patients with myopic foveoschisis and foveal detachment were analysed retrospectively. All patients received an intravitreal injection of 0.2-0.3 mL C3F8 as an initial treatment. The patients were followed up for at least 18 months after the procedure. The refractive status, best-corrected visual acuity (BCVA), and anatomical abnormalities in macular area before and after the treatment were assessed and recorded.
RESULTS: After initial gas tamponade, FD resolved completely (defined as responders) in 14 eyes, resolved partially in 2 eyes (defined as partial responders), and worsened in 4 eyes (non-responders) at the 3-month follow-up visit. Vitrectomy was performed in four eyes that showed increased detachment (two cases) or developed macular hole (two cases). Repeated gas injection was performed in two recurrent cases after initial success at the 3-month follow-up, and the foveal detachment once again resolved. Overall, 70% of our cases demonstrated resolution of FD at the 3-month follow-up and the long-term responders to gas injection was 65%. The risk factors for treatment failure were: (1) The presence of optical coherence tomography (OCT)-evident premacular membranes (p = 0.03) and (2) the height of FS measured >588 µm (p = 0.009).
CONCLUSION: Our data supported that gas tamponade may be effective as an alternative treatment for selected cases of myopic FS with FD. The procedure may be especially beneficial in patients without OCT-evident premacular membranes and have low height of FS.
