Anatomical Outcome Following Indocyanine Green Assisted Internal Limiting Membrane Peeling for Stage 3 and 4 Macular Hole Surgery.
J Coll Physicians Surg Pak Jan ;27(8):486-9.

Objective: To evaluate the anatomical success of stage 3 and 4 macular hole surgery after removal of internal limiting membrane (ILM) with the help of Indocyanine green (ICG). Study Design: An experimental study. Place and Duration of Study: LRBT Tertiary Care Eye Hospital, Karachi, October 2015 to August 2016. Methodology: Twenty patients with stage 3 and 4 macular hole (confirmed by spectral domain optical coherence tomography) underwent standard 3 ports pars plana vitrectomy. Staining of ILM was performed with the help of 0.5% ICG to aid in visualization. ILM was removed by using intraocular forceps in circular fashion. Finally, gas fluid exchange with internal tamponade of SF6 20% was performed. Postoperative face down posture was maintained for seven days. Patients were followed-up for 8 months and assessment of macular hole closure was done using SD-OCT. Results: After a follow-up of 8 months, macular hole was closed in 17 eyes (85%) and vision had improved in 6 patients. Postoperative complications included cataract, hyphema and vitreous hemorrhage. Conclusion: Surgery for stage 3 and 4 macular hole with ILM peeling has high anatomical success rate. Final visual acuity is dependent on preoperative macular hole stage and visual acuity at presentation.
