Introduction. Most physicians are not familiar with postoperative changes to the orbit, so radiologists and clinicians may sometimes find it challenging to conduct a proper radiological assessment of the globe of the eye and orbital abnormalities. We present a patient with head trauma who had surgery for retinal detachment with implantation of silicone encircling bands. This case report may help clinicians recognize imaging characteristics after ophthalmic surgery to prevent misdiagnosis and unnecessary workup. Case Report. An 18-year-old man with severe head trauma was admitted to our hospital. Initial computed tomography (CT) revealed a high attenuation of intraocular silicone that could be mistaken for a hemorrhage. Ophthalmological examination and detailed ophthalmic history confirmed silicone oil in his eye for treatment of retinal detachment. Knowledge of the anatomical changes and radiological appearance of postsurgical findings following retinal detachment, including the surgical materials of silicone oil or bands, can prevent unnecessary alarm. Conclusion. Implanted ophthalmic devices, for example, silicone oil, appear similar to hemorrhages on CT and magnetic resonance imaging and cause diagnostic confusion. When in doubt, it is useful to assess the clinical presentation and obtain an accurate medical history.

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.

Purpose: To describe the excellent outcome of surgery for bilateral giant retinal tears (GRTs) with better options of endotamponade. Methods: This is a case report of a 62-year-old man who presented with bilateral GRTs and associated retinal detachment. The tear in the right eye was supero-temporal and silicone oil was used as an endotamponade. The tear in the left eye was infero-temporal and perfluorocarbon liquid was used as an endotamponade. Results: The outcome at 6 months after surgery was excellent with visual acuities of 6/6 in both eyes. Conclusion: Improved availability of endotamponade agents allows repair of bilateral GRTs to be done at the same time, with good surgical outcomes.

Increasingly, the use of autologous conditioned plasma in ophthalmic surgery in recent years has been given more preference than other blood products with similar effects. Surgical treatment of full-thikness macular hole is no exception. Domestic and foreign studies of recent years show that the use of ACP as an adhesive component in the treatment of this pathology is considered the most acceptable. However, in addition to the effective "gluing" of the macular hole, the convergence of its edges plays an important role in the postoperative anatomy of the foveolar zone. Objective: to study the effectiveness of the use of autologous conditioned plasma in the surgical treatment of full-thikness macular hole. Materials and methods of research. Patients who underwent surgery for a full-thikness macular hole with a diameter of more than 400 microns were prospectively observed. The study included 51 patients. The follow-up period ranged from 2 months to 1 year. All patients in the preoperative and postoperative periods underwent a comprehensive ophthalmological examination. Surgical technique: after a standard three-port vitrectomy (25Ga), the posterior hyaloid membrane was removed, and the ILM was peeled. With the help of a saline solution, a circular separation of the bonds between the edges of the gap and the pigment epithelium was achieved. After the subretinal fluid was removed and the induced local central retinal detachment was attached, the tear area was irrigated by ACP. After that, the air was replaced with silicone oil, which was removed after 1.5 months. Nodal sutures were applied to the sclerotomy (vicryl 8-0). Results. In 49 operated patients, anatomical restoration of the foveolar zone was achieved, which accounted for 96% of the total number of patients. Visual functions were evaluated after 1.5 months (after removal of silicone oil). Corrected visual acuity in 96% of patients ranged from 0.2 to 0.5. Conclusion. The high efficiency of the use of autologous conditioned plasma in the treatment of full-thikness macular holes allows us to achieve high anatomical and functional results. Key words: macular rupture, autologous conditioned plasma, silicone tamponade.

Introduction. The integrity of photoreceptor's inner segment/outer segment connection plays great importance in predicting visual acuity in eyes with retinal pathology. However, even optical coherence tomographic study showed the intact of retinal layers, including photoreceptor's inner segment/outer segment line, after surgery due to rhegmatogenous retinal detachment (RRD), low visual acuity is observed. Purpose. to identify predictors of high visual acuity in the foveolar zone in patients after successful RRD repair according to SD-OCT. Material and methods. Group 1 consisted of 20 cases – eyes after successful primary RRD repair performed through pars plana vitrectomy using silicone oil tamponade (1300 cSt), followed by removal of silicone oil with a replacement for sterile air. Group 2 – control, followed eyes without ophthalmopathology and visualisation of foveolar bulge according to OCT. All patients underwent a standard ophthalmological examination and OCT on the 30th day after silicone oil removal. OCT examination was performed by Retina Map and Cross Line modes. The lengths of the outer segments of photoreceptors, inner segments of photoreceptors and the outer nuclear layer of the layer were measured in manual mode. Retina Map was used to measure retinal foveolar thickness. Results. During the study, the data of the foveolar thickness of the retina, the outer nuclear layer and the length of the outer segment of photoreceptors in the main group showed a significant decrease in comparison with the control group (p=0.002, p=0.006, p=0.02, respectively). In this case, a strong correlation was obtained only between the length of the outer segments of photoreceptors and visual acuity (r=0.68). Conclusion. The length of the outer segments of the cones in the central retinal area, or foveolar bulge, should considers a predictor of high visual acuity twostage surgical treatment of primary RRD using silicone oil. Key words: retinal detachment, foveolar bulge, ellipsoid zone, vitrectomy, OCT.
