To study the evolution of lamellar macular holes (LMHs) using spectral domain-optical coherence tomography (SD-OCT).
Celal Bayar University Hospital Department of Ophthalmology
Thirty-one consecutive patients diagnosed with a LMH were followed prospectively at Celal Bayar University Hospital. Inclusion criteria were a foveal defect on SD-OCT with residual foveal tissue above the retinal pigment epithelium. LMHs were quantitatively and qualitatively characterised by SD-OCT in terms of base and apex diameter and residual foveal thickness. Best corrected visual acuity (BCVA) and SD-OCT findings were collected and compared at baseline and at final examination.
The patients included 15 males and 16 females with a mean age of 63.9 ± 2.15 years. The mean follow-up period was 21.95 months (range 12-79 months). The mean BCVA (logMAR) at baseline was 0.45±0.18 , and at final examination it was 0.42±0.11 (p>0.05). Residual Foveal thickness at baseline (184,25±31.25 µm), was also stable at the final visit (182±22.36 µm, p>0.05). Moreover, we did not observe statistically significant differences regarding apex (589±82.20 vs 615±93.25 µm, p>0.05) and base (828±76.14 vs 842±80.65 µm, p>0.05) diameters . Any patient developed a full thickness macular hole during the follow-up period.
Most lamellar macular holes do not progress anatomically and do not contribute to a significant decrease in visual acuity during the follow-up period. Vitrectomy should be considered only in the presence of progressive thinning of foveal thickness and/or decrease of visual acuity during the follow-up of the disease.
