Abstract Details

Purpose:

To evaluate the optical coherence tomography angiography (OCT-A) features of patients who had successful macular hole (MH) surgery

Setting:

Ankara University, Medical Faculty, Department of Ophthalmology Observational case study

Methods:

10 patients who underwent surgery in a single eye due to MH included to the study. Vascular densities, flow indexes and nonflow indexes in superficial and deep retinal capillary plexuses of patients’ both surgical and healthy fellow eyes evaluated by OCT-A

Results:

The mean age of patients was 64.1 ± 8.6 y (47–78 y) and the mean follow-up period was 20 ± 12.8 mo (range: 6–39 mo). There was no statistically significant difference between surgical and healthy eyes in terms of both superficial and deep capillary plexus mean vascular densities (45.8% vs 47.3%, p=0.344 and 45.8% vs 50.3%, p=0.175). The mean flow indexes of both superficial and deep capillary plexus were significantly lower in surgical eyes in compare to healthy fellow eyes (0.73 vs 0.91, p=0.03 and 0.38 vs 1.08, p=0.025), while the mean nonflow indexes of both superficial and deep capillary plexus were significantly higher in surgical eyes in compare to healthy fellow eyes (7.81 vs 0.85, p<0.0001 and 20.93 vs 7.62, p=0.002).

Conclusions:

These preliminary results may be one explanation for the unsatisfactory visual gain after surgery, despite successful anatomical closure of MHs.
