Abstract Background: ellipsoid zone (EZ) layer plays a vital role in visual performance of human retina, hereby we try to find some risk factors for EZ integrity after primary macula-off rhegmatogenous retinal detachment (RRD) repair. Methods: a retrospective cases study. Patients with macula-off RRD undergoing successful primary retinal repair surgery were reviewed and spectral domain optical coherence tomography images of them were analyzed. Comprehensive preoperative, intraoperative and postoperative clinical factors were screened. Results: A total of 118 patients (118 eyes) were enrolled in this study. The mean age of those patients was 52.16 years old (52.16 ±12.87 years). The follow-up time ranged from 0.1 to 84 months (10.21 ±14.81 months). 54 cases (45.76%) had their EZ fully reconstructed at final visit. The mid-quartile time of EZ reconstruction was 14.0 months (95% CI: 11.3 ~20.0 months). Multivariate proportional haphazard regression test revealed that the independent factors were: silicone oil tamponade (Hazard ratio=0.414, p=0.0400), posterior staphyloma (Hazard ratio=0.141, p=0.0021) and disorganization of retinal inner layer (Hazard ratio=0.167, p=0.0166). Conclusion: After successful retinal reattachment for macula-off retinal detachment, the mid-quartile time of EZ recovery was about 14 months. The independent risk factors for EZ recovery might include silicone oil tamponade, posterior staphyloma and disorganization of retinal inner layer.

Purpose. To compare the parameters of a light sensitivity (LS) of the central zone of a retina after vitrectomy due to reghmatogenous retinal detachment (RRD) with a silicone oil tamponade (SOT) and gas tamponade (GT). Material and methods. The study included 20 eyes after pars plana vitrectomy due to macula-off rhegmatogenous retinal detachment (RRD) by 25G. All patients were divided in 2 groups depending on the choice of the tamponade. The group I (10 eyes) included cases with the silicone oil tamponade (SOT) (1300 cSt), in the group II (10 eyes) – the gas tamponade (GT) (C2F6). The control group included contralateral eyes without ophthalmic pathology. All patients underwent standard ophthalmological examination and fundus- microperimetry (FMP) on the 30th day after removal of the SOT for the group I, or on the 30th day after the C2F6 tamponade for the group II. Results. According to FMP data, the parameter of average light sensitivity (LS) in the group I was significantly reduced, both in comparison with the group II (p=0.007) and the control group (p=0.003). Differentiation by zones in the group I revealed a decrease in each analyzed parameter in comparison with the control group (p<0.05) and a decrease in the 2nd zone (p=0.031) and the 4th zone (p=0.038) in comparison with the group II. In the 1st zone of the group I the formation of a relative scotoma was revealed in 4 cases out of 10 (40%). The parameters of light sensitivity (LS) in comparison with the control in the group II were significantly reduced when analyzed in each zone (p<0.05). A strong positive correlation was found between the Best Corrected Visual Acuity (BCVA) and the average LS in the group II (r=0.87). Conclusion. There is a decrease in the functional parameters of the retina with SOT compared with GT in the form of a decrease in the LS parameter in the 10° zone according to FMP data. Key words: retinal detachment, photosensitivity, microperimetry, silicone tamponade.

Purpose: Assess changes on spectral domain optical coherence tomography (OCT) before, during, and after removal of silicone oil (SO). Methods: Retrospective series of patients who underwent SO tamponade for macula-on rhegmatogenous retinal detachment. OCT scans of the affected eye were taken before, during, and 3 months after SO tamponade. Qualitative assessment of foveal contour and quantitative comparison of OCT parameters (central macular, cube, ganglion cell layer [GCL], and outer retinal thicknesses) were done between 3 time points. Results: Ten eyes of 9 patients were included. Flattening of the foveal contour during SO tamponade was completely reversed after SO removal. Average cube and GCL thicknesses decreased with SO tamponade and increased after SO removal ( P = .01 and P = .02, respectively). Outer retinal thicknesses did not vary among 3 time points ( P = .09). Conclusions: SO tamponade causes foveal flattening and thinning of the inner retinal layers, which is reversible on removal.

<b><i>Purpose:</i></b> The aim of the study was to investigate the effect of tamponade duration on retinal changes induced by silicone oil (SO) in patients who underwent successful rhegmatogenous retinal detachment (RRD) surgery. <b><i>Methods:</i></b> Retrospective comparative case series of 68 patients who underwent SO tamponade for RRD. Patients were divided into 2 groups based on timing of SO removal: &#x3c;6 months (group 1, <i>n</i> = 34) versus ≥6 months (group 2, <i>n</i> = 34). The main outcome measure was the change in central macular, inner, and outer retinal layer thickness (CMT, IRLT, and ORLT) before and after SO removal (SOR). <b><i>Results:</i></b> The median tamponade duration was 4 [Clin Ophthalmol. 2016;10:471–6, Zhonghua Yan Ke Za Zhi. 1997 Jan;33(1):39–41] months in group 1 and 8 [Arch Ophthalmol. 1994 Jun;112(6):778–85, Retina. 2004 Dec;24(6):871–7] months in group 2 (<i>p</i> &#x3c; 0.001). The mean CMT significantly increased from 245.3 ± 22.2 μm and 238.8 ± 41.6 μm under SO to 281.3 ± 60.2 μm and 259.0 ± 43.5 μm after SOR in group 1 (<i>p</i> = 0.009) and in group 2 (<i>p</i> = 0.007), respectively. Automated segmentation measurement revealed a significant increase in mean IRLT (<i>p</i> = 0.014 and <i>p</i> = 0.013) but no change in mean ORLT (<i>p</i> = 0.080 and <i>p</i> = 0.257) in both groups. After adjustment, there was no difference between the 2 groups in terms of mean final CMT, IRLT, and ORLT and mean retinal thickness changes after SOR. There was also no correlation between the tamponade duration and macular microstructural changes or visual recovery. <b><i>Conclusion:</i></b> SO tamponade causes a thinning of all retinal layers, mainly affecting the inner retinal layer. However, these changes resolved following SO extraction and were not affected by longer tamponade duration.

Purpose: To investigate clinical and surgical factors influencing the outcome after primary rhegmatogenous retinal detachment surgery. Methods: A retrospective, single-centre, case-control study of 1017 eyes of 1017 consecutive patients with primary rhegmatogenous retinal detachment (RRD) who underwent pars plana vitrectomy (PPV), were included in the study. Analysed surgical factors were: combined procedure with phacoemulsification, type of retinopexy (cryocoagulation, endolaser, combined), type of tamponade (gas, silicone oil), and anatomical factors: primary proliferative vitreoretinopathy (PVR) and macular detachment at the time of surgery. Results: Overall retinal re-detachment rate was 10.1%. The main reason for re-detachment was an insufficient retinopexy in 53.6%, followed by PVR (37.3%), and retinal detachment occurred at a different location caused by another break in 9.1%. No significant difference in the rate of re-detachment was found if a phacoemulsification with simultaneous IOL implantation was performed (p = 0.641). No significant difference between the various retinopexy techniques was found (p = 0.309). Risk factors re-detachment were primary PVR (p = 0.0003), silicone oil as initial tamponade (p = 0.0001) as well as macula off detachments (p = 0.034). Conclusions: The present study showed no significant difference between the types of retinopexy and if additional phacoemulsification was performed or not. Factors associated with a higher risk for re-detachment were detached macula at surgery, primary PVR and primary oil-filling.
