Purpose: In retrospective study to compare echographic features of posterior vitreous face and vitreo-macular region with preoperative findings by pars plana vitrectomy of idiopathic macular hole. Material and Method: The group includes 27 eyes with idiopathic macular hole. 11 in II. and 16 in III. stage by Gass’s surface spike; 4. 10-times (37,0 %) the combination of 1. - 3. and/or some other pathology of vitreous. 3 eyes (11,2 %) were without relevant pathologic echographic findings. Preoperatively was1. the presence of a pseudooperculumconfirmed in 9 eyes (33,3 %). 6-times (22,2 %) the posterior vitreous face had separated by core vitrectomy, no active elevation was needed. In 21 eyes (77,8 %) the active elevation of posterior vitreous face was performed, 6-times (28,4 %) was the elevation more difficult. Conclusion: Echographic features of posterior vitreous face and vitreomacular region correlate with preoperative findings by pars plana vitrectomy and determine a strategy of surgical intervention.clasification. The spectrum of identifiable echographic features included: 1. partial posterior vitreous face separation; 2. presence of a pseudooperculum; 3. high spike of posterior vitreous face over the macula and/or optic nerve head and 4. combination of these findings, eventually some other pathology of vitreous. Peroperative clinical findings included: 1. presence of a pseudooperculum; 2. facility of elevation and separation of posterior vitreous face. Results: The echographic findings showed: 1. 5-times (18,5 %) partial posterior vitreous face separation; 2. 5-times (18,5 %) the presence of a pseudooperculum; 3. 4-times (14,8 %) the high spike of posterior vitreous face in front of the retinal
