@entity1 @entity2994
PURPOSE: To evaluate the posterior vitreous adhesion status in @entity1 with a history of central or branch @entity2994 and to compare the results with the natural time-course of posterior vitreous detachment in healthy age-related controls. METHODS: A retrospective chart review in terms of the posterior vitreous adhesion status was performed in 132 @entity1 (133 eyes) with a history of a central (CRVO) or branch (BRVO) @entity2994 . All @entity1 underwent vitrectomy. Based on the operation reports, the vitreous adhesion status was classified as attached, partially detached or completely detached. The results were compared to the natural time-course of posterior vitreous detachment development in healthy age-related controls. RESULTS: Eighty-one eyes met the inclusion and exclusion criteria. Fifty-two eyes (64%) had a history of CRVO and 29 eyes (36%) a history of BRVO, respectively. In the CRVO group, the posterior vitreous was attached in 47 eyes (90%) and completely detached in five eyes (10%). In the BRVO group, the posterior vitreous was attached in 27 eyes (93%), partially detached in 1 eye (3%) and completely detached in another eye (3%). A subdivision into age classes and a comparison with healthy age-related controls [data by Weber-Krause _ Eckardt (1997) Ophthalmologe, 94, 619-623] showed in @entity1 between 65 and 69 years of age an attached posterior vitreous cortex in 72% in healthy eyes, in 100% in CRVO (p = 0.109) and in 89% in BRVO (p = 0.440), in @entity1 between 70 and 79 years of age an attached posterior vitreous cortex in 56% in healthy eyes, in 86% in CRVO (p = 0.010) and in 100% in BRVO (p = 0.038) and in @entity1 between 80 and 89 years of age an attached posterior vitreous cortex in 43% in healthy eyes, in 100% in CRVO (p = 0.191) and in 67% in BRVO (p = 0.582) (Fisher's exact t-test). CONCLUSION: In @entity1 with a history of CRVO or BRVO, the posterior vitreous cortex stays attached more frequently in all age groups in comparison with the healthy age-related controls.
