Abstract

Purpose: To find the most reliable and efficient non-invasive technique to detect a posterior vitreous detachment.
Design: In a prospective study on 30 eyes of 30 patients with macular pucker or macular hole formation the posterior vitreous cortex was examined by three independent investigators via slit-lamp biomicroscopy, 10 MHz b-scan ultrasound and optical coherence tomography via OCT III Stratus® (Carl Zeiss Meditec Inc. Dublin, CA) and RTVue-100-OCT (Optovue Corp., Fremont, CA). In each examination the state of the posterior vitreous adhaesion was classified as “attached“ or “detached“. These findings were compared during a triamcinolone-acetonide-assisted vitrectomy one day later.
Results: Vitrectomy showed in 60% a posterior vitreous detachment and in 40% an attached posterior vitreous cortex. B-scan ultrasound and biomicroscopy revealed the highest, correct evaluation of the posterior vitreous status with 83% and 76% respectively. The prediction of the OCT only applied in 12.5% of all cases. In all other cases the evaluation by OCT was not possible or inadequate.
Conclusion: The prognostic most reliable, but investigator-dependent methods to detect whether the posterior vitreous cortex is detached, are b-scan-ultrasound and biomicroscopy. The objective technique of the high-resolution, two-dimensional time-domain OCT allows only in a few cases a clear differentiation of preretinal structures.
