ABSTRACT.Purpose: To evaluate the posterior vitreous adhesion status in patients with a history of central or branch retinal vein occlusion and to compare the results with the natural time-course of posterior vitreous detachment in healthy agerelated controls. Methods: A retrospective chart review in terms of the posterior vitreous adhesion status was performed in 132 patients (133 eyes) with a history of a central (CRVO) or branch (BRVO) retinal vein occlusion. All patients 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 WeberKrause & Eckardt (1997) Ophthalmologe, 94,[619][620][621][622][623] showed in patients 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 patients 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 patients 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 patients 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.

Three years after SMILE, there was a reduction of posterior astigmatism in high refractive corrections. This could result in undercorrection in high refractive treatments. Total irregularities increased despite the compensatory effect of the posterior corneal surface.

The aim of this clinical trial was to check the results of laser built-in settings 3 years after ReLEx SMILE for moderate and high myopia in unselected "real life" patients. 50 myopic eyes of 27 patients were called in for examination after 3 years. 25 of these eyes with a preoperative myopia under - 6D comprised the "moderate myopia subgroup". All surgeries were performed with the 500 kHz VisuMax® femtosecond laser (Carl Zeiss Meditec AG, Jena) in the "fast mode" setting. The spherical equivalent (SE) of the entire group changed from - 6.18 D (± 1.91) prior to surgery to - 0.18 D (± 0.39) 3 years later. The preoperative SE in the moderate myopia subgroup changed from - 4.71 D (± 0.94) to - 0.04 D (± 0.23). 14 % of 50 eyes gained one line and 22 % lost one line of CDVA. The regression between month 3 and 36 was 0.07D for the entire group and 0.06 D for the moderate myopia subgroup. There were no late side effects. Primary undercorrection was predominantly seen in eyes over - 6 D. ReLEx SMILE shows remarkable stability over the entire range of myopias after 3 years, however primary undercorrection occurs predominantly in eyes of - 6.0 D, which necessitates nomogram adjustment.

Compared with SD-OCT, resolution of the 1 mm retinal B scan of SS-OCT scan biometry was lower. However, advanced pathologic characteristics were clearly discernible. Repeatability and accuracy of CRT measurements were acceptable though lower than with the standard SD-OCT technique. The CRT differed significantly in eyes of particular interest (group I) between both devices. The new scan could provide useful information for subsequent patient examination and further treatment planning for cataract surgery.
