MACULAR BUCKLING COMBINED WITH VITRECTOMY AND INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE FOR MACULAR HOLES WITH MACULAR RETINOSCHISIS WITHOUT RETINAL DETACHMENT IN HIGH MYOPIA

imagePurpose:

To investigate the outcomes of macular buckling combined with vitrectomy and inverted internal limiting membrane flap technique for highly myopic full-thickness macular hole (FTMH) with macular retinoschisis.

Methods:

Twenty-six eyes of 26 consecutive patients were retrospectively included. Twelve eyes underwent macular buckling alone (buckling group). Fourteen eyes underwent macular buckling and vitrectomy with an inverted internal limiting membrane flap technique (combination group). Patients were followed for at least 9 months. Rates of FTMH closure and macular retinoschisis resolution, best-corrected visual acuity gained at the final visit were evaluated.

Results:

The mean follow-up time was 13.00 ± 3.16 months. FTMH closed in six eyes (50%) of the buckling group and 13 eyes (92.86%) of the combination group (P = 0.026) at the final visit. The macular retinoschisis resolution rate was close between two groups (100% vs. 92.86%; P = 1.000). Both groups achieved significant improvement in best-corrected visual acuity (10.42 ± 17.25 and 16.36 ± 10.39 Early Treatment Diabetic Retinopathy Study letters; P = 0.014 and P

LONGITUDINAL ASSESSMENT OF CHOROIDAL STRUCTURE IN PATIENTS WITH MACULAR NEOVASCULARIZATION

imagePurpose:

To investigate morphologic changes of choroidal structure through chronologic aspect in progression of macular neovascularization (MNV) with pachychoroid features.

Methods:

One hundred seventy-one MNV participants above 50 years old with or without pachychoroid features were included in the analysis. Age-matched 132 normal patients were analyzed as control group. The total choroidal area and ratio of Sattler’s layer area to total choroidal area, derived by summing 25 horizontal raster scans of the 30° × 20° scan area on enhanced depth imaging optical coherence tomography, were calculated to compare the difference among the normal eyes and the MNV eyes with/without pachychoroid features.

Results:

The mean ratio of Sattler’s layer area to total choroidal area is maintained at around 40% in normal eyes and MNV eyes without pachychoroid features. In MNV with pachychoroid features, the ratio of Sattler’s layer area to total choroidal area changes according to the disease activity. Ratio of Sattler’s layer area to total choroidal area is 34.1 ± 4.4% at the time of onset, 37.2 ± 4.8% at the time of remission, and decreases during recurrence from 36.8 ± 3.8% to 33.4 ± 3.8% (all P
