Abstract Details



Purpose:

To evaluate foveal changes and the relationship between foveal structure and best corrected visual acuity (BCVA) following successful retinal detachment surgery.

Setting:

Karadeniz Technical University, Medical Faculty, Ophthalmology Clinic, Trabzon, TURKEY

Methods:

64 patients undergoing successful detachment surgery were enrolled retrospectively. Patients were followed-up for a mean duration of 12 months. BCVA, ISOS junction and foveal thickness at OCT were assessed at 12 months, and the correlations between them were investigated.

Results:

BCVA was 0.61± 0.57 LogMAR, foveal thickness was 226.6 ± 134.4 µm and the level of healthy ISOS junctions was 37.5% in the 20 macula-on and 44 macula-off patients at postoperative 12th month examination. C3F8 and 1000 cs silicone oil were used as tamponades in 15 and 49 patients, respectively. BCVA was significantly higher in the group using C3F8 than in the silicone group (p = 0.001). No significant correlation was determined between tamponade used and changes in the ISOS junction and BCVA, whereas significant correlation was determined between the state of the macula and BCVA and ISOS junction changes (r = 0.485, p = 0.001 and r = 0.578, p = 0.001). No significant correlation was determined between the time to surgery after detachment and ISOS junction changes and BCVA.

Conclusions:

Deterioration of the ISOS junction and preoperative macular detachment are factors that have an adverse effect on BCVA in rhegmatogenous detachment.
