Sudden branch macular artery avulsion during internal limiting membrane peeling for idiopathic macular hole: A case report.

ABSTRACT:

Introduction and importance

Macular Holes (MH) are variable thickness openings of the retina that develop in the fovea. This case presents a branch macular artery avulsion during internal limiting membrane (ILM) peeling for idiopathic macular hole management in an adult patient. The proper management of this complication along with the preventive measures is mentioned.

Case presentation

A 65-year-old woman developed a branch macular artery avulsion during ILM peeling for MH. After cataract extraction by phacoemulsification with intraocular lens implantation and pars plana vitrectomy, during ILM peeling, a multifocal bleeding along a macular artery was noted indicating its avulsion. The intraocular pressure was raised to control hemorrhage, blood remnants were passively aspirated and ILM peeling was kindly completed under adequate visualization.

Clinical discussion

Branch macular artery avulsion is a potential complication even for experienced surgeons. Proper management of this complication involves the increase of intraocular pressure for hemostasia. If hemostasia and proper visualization are achieved, the surgery could be completed, and if it is not the case, the ILM peeling could be completed in a second procedure. This complication might be avoided by initiating the ILM peeling away from the macular vessels.

Conclusion

Branch macular artery avulsion is an intraoperative complication that might be avoided by initiating the ILM peeling away from the macular vessels.

Project description:BackgroundThe internal limiting membrane (ILM) insertion technique was widely used to treat large macular hole (MH) for the high closure rate. However, the prognosis of closed MH after ILM insertion compared to ILM peeling remains controversial. This study aimed to compare foveal microstructure and microperimeter in large idiopathic MH surgically closed by ILM peeling and ILM insertion.MethodsThis retrospective, non-randomized, comparative study included patients with idiopathic MH (minimum diameter ≥ 650 μm) who underwent primary pars plana vitrectomy (PPV) with ILM peeling or ILM insertion. The initial closure rate was recorded. Patients with initially closed MHs were divided into two groups according to the surgery methods. The best-corrected visual acuity (BCVA), optical coherence tomography (OCT) and microperimeter-3 (MP-3) outcomes of two groups were compared at baseline, 1 and 4 months postoperatively.ResultsFor idiopathic MH (minimum diameter ≥ 650 μm), ILM insertion had a significantly higher initial closure rate than ILM peeling (71.19% vs. 97.62%, P = 0.001). Among 39 patients with initially closed MHs who were on regular follow-up, twenty-one were assigned to the ILM peeling group and 18 to the ILM insertion group. Postoperative BCVA improved significantly in both groups. The final BCVA (logMAR) (0.40 vs. 0.88, P < 0.001), macular hole sensitivity (19.66 dB vs. 14.14 dB, P < 0.001), peripheral sensitivity of macular hole (24.63 dB vs. 21.95 dB, P = 0.005), and fixation stability (FS) within 2 degrees (82.42% vs. 70.57%, P = 0.031) were significantly better and external limiting membrane (ELM) defect (330.14 μm vs. 788.28 μm, P < 0.001) and ellipsoid zone (EZ) defect (746.95 μm vs. 1105.11 μm, P = 0.010) were significantly smaller in the ILM peeling group than in the ILM insertion group.ConclusionFor initially closed MHs (minimum diameter ≥ 650 μm), both ILM peeling and ILM insertion significantly improved the microstructure and microperimeter in the fovea. However, ILM insertion was less efficient at microstructural and functional recovery after surgery.

Project description:BackgroundA full-thickness macular hole (FTMH) is a common retinal condition associated with impaired vision. Randomised controlled trials (RCTs) have demonstrated that surgery, by means of pars plana vitrectomy and post-operative intraocular tamponade with gas, is effective for stage 2, 3 and 4 FTMH. Internal limiting membrane (ILM) peeling has been introduced as an additional surgical manoeuvre to increase the success of the surgery; i.e. increase rates of hole closure and visual improvement. However, little robust evidence exists supporting the superiority of ILM peeling compared with no-peeling techniques. The purpose of FILMS (Full-Thickness Macular Hole and Internal Limiting Membrane Peeling Study) is to determine whether ILM peeling improves the visual function, the anatomical closure of FTMH, and the quality of life of patients affected by this disorder, and the cost-effectiveness of the surgery.Methods/designPatients with stage 2-3 idiopathic FTMH of less or equal than 18 months duration (based on symptoms reported by the participant) and with a visual acuity </= 20/40 in the study eye will be enrolled in this FILMS from eight sites across the UK and Ireland. Participants will be randomised to receive combined cataract surgery (phacoemulsification and intraocular lens implantation) and pars plana vitrectomy with postoperative intraocular tamponade with gas, with or without ILM peeling. The primary outcome is distance visual acuity at 6 months. Secondary outcomes include distance visual acuity at 3 and 24 months, near visual acuity at 3, 6, and 24 months, contrast sensitivity at 6 months, reading speed at 6 months, anatomical closure of the macular hole at each time point (1, 3, 6, and 24 months), health related quality of life (HRQOL) at six months, costs to the health service and the participant, incremental costs per quality adjusted life year (QALY) and adverse events.DiscussionFILMS will provide high quality evidence on the role of ILM peeling in FTMH surgery.Trial registrationThis trial is registered with Current Controlled Trials ISRCTN number 33175422 and Clinical Trials.gov identifier NCT00286507.
