We enrolled to a cross-sectional study 21 patients that underwent in one eye scleral buckling surgery with episcleral implant due to macula-on rhegmatogenous retinal detachment. All participants were examined bilaterally at least 6 months after the operation using optical coherence tomography angiography (OCT-A) to assess VD and Spectral domain OCT (Sd-OCT) to assess thickness of IRL. Retinal sensitivity was tested with microperimetry (MP). A direct comparison of the retinal sensitivity, VD and IRL thickness between the operated eye and the fellow normal eye was received by normalizing the obtained values as percentage loss.
The intereye comparison showed that the most significant changes after scleral buckling surgery were observed in OCTA in the radial peripapillary capillaries VD (13,9%) then in the deep and superficial vascular plexus (11.5%). It was observed difference in the retinal ganglion cell complex thickness (8.6%) in Sd-OCT , as well as decreased retinal sensitivity (7.6%) in MP. The percentage reduction in relation to the fellow eye was statistically significant for all tested parameters.
After the scleral buckling surgery for macula on rhegmatogenous retinal detachment adverse functional and structural changes in the macula are observed in comparison to the fellow eye. The disturbances in retinal microcirculation are more advanced than in retinal sensitivity, which may indicate the vascular pathomechanism of functional dysfunction.
