Purpose. To objectively detect true posterior vitreous cortex (PVC) adhesion status using a commercially available swept-source OCT device (DRI OCT-1, Atlantis©). Material and Methods. Case report, review of the literature, and methodical discussion of concepts to improve OCT-guided PVC imaging. Results. Standard OCT imaging misdiagnosed PVC adhesion status as totally detached in this case report when using a horizontal 6 mm scan only. Contrariwise imaging the same eye with a 12 mm horizontal scan, partial posterior vitreous detachment (PVD) and the presence of a bursa premacularis were clearly discernible. Besides a broader scan, specific scan patterns, highest resolution, and contrast sensitivity, an anterior-to-posterior adjusted scan through the entire vitreous as well as the detection of characteristic undulating aftermovements might enhance the capability of OCT imaging to detect true PVC adhesion status. Conclusions. Further developments are needed to address these issues and to establish OCT recordings as the standard and objective method of choice in PVC adhesion status imaging.

Posterior Vitreous Cortex

AIM: To describe a quick, cost-effective alternative to using a scraper to remove the residual posterior vitreous cortex and create an inner limiting membrane (ILM) flap during vitrectomy. METHODS: The surgical technique and a retrospective interventional single-center series of cases were described. A hook was made on the tip of a conventional syringe needle (outer diameter, 0.6 mm; 23 gauge) by bending the needle against a plate. We used this hook to remove the residual posterior vitreous cortex and create an ILM flap during vitrectomy. The efficacy and safety of using this instrument in ophthalmological procedures for a variety of vitreoretinal disorders were evaluated. RESULTS: The hook was effective for removing focal or diffuse residual posterior vitreous cortex in eyes with rhegmatogenous retinal detachment, proliferative diabetic retinopathy, and pathological myopia. It was also successfully used to make a free edge of the ILM and help strip the epiretinal membrane. There were no serious complications associated with using the hook in delicate ophthalmological procedures. CONCLUSION: The hook, made by bending a conventional needle, is a simple and cost-effective instrument for removing residual posterior vitreous vortex and to create epiretinal and ILM flaps during vitrectomy in eyes with various vitreoretinal diseases.
