To identify the prognostic indicators for anatomical closure and improved visual outcome of lamellar macular hole (LMH) managed with small gauge vitrectomy
A retrospective observational case series
27 eyes of 27 consecutive patients diagnosed with LMH were reviewed. All eyes underwent small gauge vitrectomy with ILM peel and gas. Preoperative and postoperative visual acuities (VAs) were compared and the anatomical outcome of vitrectomy was examined by studying the restoration of the foveal contour on optical coherence tomography (OCT) scans.
27 eyes had improved anatomical and functional outcome after surgery. Anatomical closure of the LMH was achieved with a single surgical procedure in all eyes. Visual acuity improved significantly in 80 % of cases. Preoperative VA, preoperative central foveal thickness, size of the defect, timing of surgery, the presence or absence of LMH associated pre-retinal proliferation were used to assess the probability of anatomical and functional success.
As vitrectomy for LMH is still controversy, those prognostic parameters have to be considered when counselling LMH patients for surgery
