Purpose: To evaluate usefulness and safety of removal of silicone oil from the vitreous cavity via the anterior chamber. Methods: The procedures were performed between 2012 and 2020 in 31 patients who required endotamponade with the use of light silicone oils. In most of the patients, the procedure was combined with cataract removal, secondary lens implantation or transscleral fixation of an artificial lens. A passive bimanual technique was used to replace silicone oil with fluid. Results: The procedure to remove silicon oil via the anterior chamber proceeded without serious intra- and postoperative complications. There were no hypotony observed in first postoperative day. Conclusion: Patients eligible for the procedure are those who have preoperative indications for silicone oil removal and whose removal path via the anterior chamber is not associated with a special need to remove the lens from the eye.

The purpose of this study is to conduct a comparative analysis of the correction of aphakia by various models of intraocular lenses using silicon oil tamponade (SO) of the vitreous cavity. Materials and methods. The studies were conducted on 16 eyes of patients aged from 56 to 75 years (65.5±12 years) with aphakia and pathology of the vitreal cavity. The duration of the silicone tamponade was 2-3 months. Depending on the use of the type of IOL, all patients were divided into 2 groups. Results. When using an anterior chamber intraocular lens (IOL), the presence of ophthalmic hypertension was revealed in 75% of cases, which is 2.02 times higher than when using transcleral IOL fixation. In 37.5% of cases, the SO output to the anterior chamber is determined, in contrast to the group where IOL hemming was used. A higher percentage of SO migration to the anterior chamber of the eye in group 2 patients is due to a violation of the anatomy of the anterior chamber barrier and the vitreal cavity. Conclusion. Thus, in patients who underwent transcleral IOL fixation, visual acuity is 2.1 times higher than in patients who were implanted with an anterior chamber IOL. Transcleral fixation of the IOL can form the necessary barrier between the anterior and posterior chambers of the eye, and is also the closest IOL position to the physiological one. Key words: intraocular lens, silicone oil, transcleral fixation.

Purpose. To conduct a comparative analysis of two groups of patients according to the results of cataract phacoemulsification in combination with the silicone oil removal through flat part of the ciliary body and posterior capsulorhexis in the long term after retinal detachment surgery. Material and methods. 30 patients with a diagnosis of cataract, avitria, tamponade of the vitreous cavity with silicone oil OXANE 5700 were under observation. Patients were randomly divided into two groups. In both groups, the infusion system was installed through port 25 Ga located 3–4 mm from the limb, cataract phacoemulsification was performed in the first stage. In the first group (15 patients), silicon oil was removed through the posterior capsulorexis using a curved aspiration cannula of caliber 18 Ga. In the second group (15 patients) silicon oil was removed using aspiration through the second port of 25 Ga. The assessment of the functional and anatomical state after surgery was based on data from visometry, autorefractometry, ultrasound B-scanning of the vitreous cavity, and optical coherence tomography of the macular area. Assessment of patient satisfaction with the subjective level of quality of life was carried out using the validated visual function questionnaire Visual Function (VF-14). Results. In both groups, on average, there was a significant increase in the best corrected visual acuity. According to B-scan data, emulsified silicone oil particles were less detected in patients after removal of silicone oil through posterior capsulorexis. The subjective level of quality of life of each patient improved significantly in both groups. Conclusion. Performing the combined operation of cataract phacoemulsification with the removal of silicone oil through the posterior capsulorhexis in comparison with the silicone oil removal through the flat part of the ciliary body can equally improve visual function. Satisfaction with treatment results was slightly higher in the group with silicone oil removal through posterior capsulorexis. Key words: cataract, avitria, silicone oil, posterior capsulorexis.

Abstract Purpose To test the antimicrobial properties of silicon oil (Aurosil 1000 cSt, Aurosil Plus 5000 cSt) on in vitro growth of common microorganisms causing endophthalmitis. Materials and methods Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, multi-drug resistant (MDR) strain of Klebsiella pneumoniae, Escherichia coli, Candida albicans, and Aspergillus flavus were prepared to 0.5 McFarland turbidity. The bacteria and fungi were inoculated into the silicone oils, brain heart infusion (BHI) broth for bacteria and Sabouraud dextrose agar (SDA) broth for fungi, respectively, and cultured aerobically for 30 days. From each sample, 10 μl was plated onto nutrient agar and potato dextrose agar (PDA) for testing growth of bacteria and fungi respectively. Cultures from specimens, overnight incubation, and CFU counting were repeated on days 1, 3, 5, 7, 14, 21, 24, and 30. Negative controls were brain heart infusion and physiologic saline as well as silicone oils without any inoculations. Results All bacteria showed a decrease in CFUs by the fifth day and eliminated between 21 and 30 days in silicone oil. The silicon oil, irrespective of its viscosity, had only fungistatic effect up to 30 days. Colony-forming units of microorganisms remained stable in physiologic saline during the study. In BHI and Sabouraud broth, both bacteria and fungi showed a growth pattern that was compatible with the growth curve of microorganisms. Conclusion Medical-grade silicone oil used in ophthalmology exhibited in vitro bactericidal and fungistatic activity over 30 days. Insertion of silicone oil in vitrectomy for endophthalmitis, when required, could supplement the antimicrobial activities of intravitreal antibiotics in management of endophthalmitis.

ABSTRACT Introduction Silicone oils are used in vitreoretinal surgery and it helps in maintaining the shape and fullness of the orbital globe. Rarely, they may get leaked from the orbit and may track to the brain in cerebrospinal fluid spaces like cisterns, ventricles. This can be documented by computed tomography with hyperdense oil. We are presenting a very rare case of the orbital silicon oil seepage into the ventricle. We report the role of multidetector computed tomography to see silicone oil migrating from orbits to the brain. Not many cases are reported in the literature.
