| Summary: | Purpose: To compare morphological features of staphyloma (type and grade) with structural and functional outcomes in 11 patients with symptomatic myopic tractional maculopathy (MTM) who underwent macular buckle surgery. Methods: A retrospective observational case series, where a chart review was conducted of the type (Curtin classification) and grade of staphyloma (USG B-scan based). Optical coherence tomography (OCT) macula analysis done preoperatively and postoperatively 1 and 6–8 weeks), Visual acuity was recorded in log mar. Results: With an average myopia of −10.35 D (−5 to −14.5 D), there were four patients with types II and IX staphyloma and seven with type I staphyloma. The average axial length was 28.6 ± 0.98 mm in type II/IX and 26.2 ± 0.8 mm in type I. Preoperative OCT features were outer retinal layer schisis (11), retinal detachment (foveal: 2, macular: 8), macular hole (lamellar: 3, full thickness: 4), and taut posterior hyaloid (3). Postoperatively, patients with type II/IX staphyloma had significant gain in visual acuity from 1.05 ± 0.3 to 0.74 ± 0.2 Log Mar. The structural features also responded better in patients with types II/IX staphyloma, with all patients having more than 90% reduction in schisis and retinal attachment at 6 weeks. Whereas only two patients with type I staphyloma had similar reduction in schisis at 6 weeks and only one had complete retinal attachment. Conclusion: In patients with MTM, the staphyloma characteristics preoperatively can help us prognosticate about structural and functional success after macular buckle surgery. In our small case series, patients with type II/IX staphyloma and larger axial length had better structural and functional outcomes. |
