Summary

Three-dimensional spectral domain optical coherence tomography (3D SD-OCT) revealed an optically empty space beneath the retinal pigment epithelium in highly myopic eyes. This imaging technique aids in understanding peripapillary detachment of the pigment epithelium and planning surgical interventions.

Background:

High myopia is associated with various posterior segment pathologies.
Peripapillary detachment of the pigment epithelium (PDPM) and myopic retinoschisis are challenging conditions in highly myopic eyes.
Vitreoretinal tractions can contribute to complex retinal pathologies.

Observation:

Three-dimensional spectral domain optical coherence tomography (3D SD-OCT) was utilized to examine four highly myopic eyes (2 patients).
The study focused on eyes presenting with peripapillary detachment of the pigment epithelium (PDPM), vitreoretinal tractions, and myopic retinoschisis.
3D SD-OCT imaging revealed an optically empty space located beneath the retinal pigment epithelium (RPE) in PDPM cases.

The optically empty space beneath the RPE in PDPM suggests a potential peripapillary separation of the retina-RPE complex from the choroid.

3D SD-OCT provides detailed visualization of the anatomical structures involved in these complex myopic retinal conditions.

The imaging modality effectively captured the characteristics of vitreomacular tractions.

Implications:

Understanding the nature of the optically empty space in PDPM can refine diagnostic approaches.
3D SD-OCT imaging is valuable for surgical planning in patients with myopic posterior detachment, particularly those with macular holes.
This study highlights the utility of advanced OCT technology in managing complex retinal pathologies in high myopia.
