Abstract
PURPOSE
To analyse morpho-functional foveal changes in eyes with lamellar macular hole (LMH) by an integrated assessment of short-wavelength fundus autofluorescence (SW-FAF) and microperimetry (SW-FAF/microperimetry integrated assessment) before and after treatment with a technique of double-inverted flaps of epiretinal proliferation (EP) and internal limiting membrane (ILM).
METHODS
Clinical and tomographic parameters were best-corrected visual acuity (BCVA), LMH size, central retinal thickness (CRT) and outer retinal layer integrity. SW-FAF/microperimetry integrated assessment allowed to analyse retinal sensitivity (RS) and FAF status of the fovea by an overlay of RS map on SW-FAF image. Follow-up was at baseline, 1, 3, 6 and 12 postoperative months.
RESULTS
Forty pseudophakic eyes. Hyper-FAF area was associated with larger LMH size (p = 0.0073) and inversely correlated with CRT (p = 0.021). Lower preoperative RS was observed in hyper-FAF than normo-FAF areas (p = 0.0117). External limiting membrane (ELM) defect was associated with worse BCVA (p = 0.0004). After surgery, BCVA improved (p = 0.001) and it was related to ELM recovery (p = 0.00483), hyper-FAF area decreased (p = 0.001), and RS increased (p = 0.440). Hyper-FAF points that normalized their FAF were associated with higher RS improvement compared to unchanged points.
CONCLUSION
Short-wavelength fundus autofluorescence/microperimetry integrated assessment provides important information on the entity of damage of LMH and on postoperative recovery. Double-inverted EP and ILM flap technique is safe and effective for LMH treatment.
