Abstract BackgroundTraction retinal detachment is one of the serious complications of proliferative diabetic retinopathy (PDR) and poses a serious threat to the visual acuity of patients.The purpose of this paper is to investigated the risk factors of tractional retinal detachment (TRD) in non-silicone oil tamponade eyes after vitrectomy for PDR.MethodsWe performed a retrospective review of patients with postoperative TRD who underwent vitrectomy with non -silicone oil tamponade (C3F8, sterilized air or BSS) for PDR. The clinical information, including laboratory tests and the history of ocular treatment, was determined and compared to the control group to analyze their significance.ResultsThe control group consisted of 28 patients who underwent vitrectomy with non-silicone oil tamponade for PDR immediately one proceeding and one following the surgery of each of the 14 patients (TRD group) with postoperative TRD. The history of photocoagulation, serum albumin, blood urea nitrogen and serum creatinine were significantly associated with TRD. The logistic regression analysis indicated that lower serum albumin concentration was the major systemic risk factor for the occurrence of TRD (P = 0.027).ConclusionThe main systemic risk factor related to TRD was serum albumin in patients with PDR who underwent vitrectomy with non-silicone oil tamponade. Preoperative albumin supplementation may reduce the risk of postoperative TRD.

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.

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.

Relevance. Information about the cardiovascular diseases risk factors (CVD RF) for in men with chronic lung inflam-matory pathology (CLID) is contradictory and requires clarification. Aim. To evaluate the peculiarities of CVD RF in men under 60 years of age with CLID in myocardial infarction (MI) to improve prevention. Material and methods. The study included men aged 19-60 years old with type I myocardial infarction. Patients are divided into two age-comparable groups: I - the study group, with CLID - 142 patients; II - control, without it - 424 patients. A comparative analysis of the frequency of observation of the main and additional cardiovascular risk fac-tors in groups was performed. Results. In patients of the study group, more often than in the control group we observed: hereditary burden of is-chemic heart disease (40.8 and 31.6%, respectively; p = 0.0461) and arterial hypertension (54.2 and 44.6%; p = 0.0461), frequent colds (24.6 and 12.0%; p = 0.0003), a history of extrasystoles (19.7 and 12.7%; p = 0.04); chronic foci of infections of internal organs (75.4 and 29.5%; p˂0.0001), non-ulcer lesions of the digestive system (26.1 and 14.6%; p = 0.007), smoking (95.1 and 66.3%; p˂0.0001), MI in winter (40.8 and 25.9%; p = 0.006). Less commonly were observed: oral cavity infections (9.2 and 23.6%; p˂0.0001); hypodynamia (74.5 and 82.5%; p = 0.0358), over-weight (44.4 and 55.2%; p = 0.0136), a subjective relationship between the worsening of the course of coronary heart disease and the season of the year (43.7 and 55.2%; p = 0.0173) and MI - in the autumn (14.1 and 21.9%; p = 0.006) period. Conclusions. The structure of CVD RF in men under 60 years of age with CLID with MI is characterized by the pre-dominance of smoking, non-ulcer pathology of the digestive system, frequent pro-student diseases, meteorological dependence, a history of cardiac arrhythmias and foci of internal organ infections. It is advisable to use the listed factors when planning preventive measures in such patients.

Purpose: To evaluate the risks that might be associated with recurrent macular hole retinal detachment (Re MHRD) after silicone oil (S.O) removal in myopic patients with open flat macular hole (MH). Methods: In this retrospective series, we assessed the different factors that might be associated with recurrent MHRD after S.O removal in 48 eyes with open flat MH that underwent S.O removal after successful MHRD repair by dividing the enrolled eyes into 2 groups: group 1 included 38 eyes with flat open MH and flat retina after S.O removal and group 2 included 10 eyes with flat open MH and recurrent MHRD after S.O removal. Results: Ten of 48 eyes (20.8%) with open flat MH developed recurrent MHRD after S.O removal. Univariate logistic regression analysis revealed that MH at the apex of PS, MH minimum diameter, hole form factor (HFF) and MH index (MHI) were significant risk factors for recurrent MHRD after S.O removal in myopic patients with open flat MH. Conclusions: If there is a "flat open" MH that is large, located at the apex of PS or with HHF or MHI of less than 0.9-0.5, it has a high chance of recurrent MHRD after S.O removal.

Purpose: Silicone oil (SO) is often used as an intraocular tamponade in repairs of retinal detachments. It may be associated with complications such as cataract, glaucoma, keratopathy, subretinal migration of oil, fibrous epiretinal and sub retinal proliferations, and oil emulsification. The purpose of this report is to describe a rare phenomenon of intraocular silicone oil migration into the cerebral ventricles, which may later be mistaken for intraventricular hemorrhages on neuroimaging. Methods: Case report with literature review. Results: A patient with a history of retinal detachment repair with intraocular SO presented with headaches. Neuroimaging revealed SO migration to the cerebral ventricles. The patient was treated conservatively with symptom management and headaches resolved. Conclusions: We present a case of intraocular SO migration to the cerebral ventricles and review the current literature. We also propose two mechanisms for this phenomenon.
