Purpose: To report a case of rhegmatogenous retinal detachment in the late stage, despite the fact that it had previously been halted after intravitreal injection of an antimicrobial agent against endogenous bacterial endophthalmitis (EBE). Case: This study involved a 62-year-old male who had previously been diagnosed with septicemia due to liver abscess and the detection of Klebsiella pneumoniae in a culture of his liver abscess, and who underwent ophthalmic examination after his conjunctival hyperemia had failed to improve. Visual acuity could not be measured due to his general condition being poor and his declining level of consciousness. Slit lamp examination revealed bilateral iritis and cataracts, and the fundus was invisible due to vitreous opacity. Ultrasonic B-mode examination showed subretinal abscess and exudative retinal detachment, leading to the diagnosis of EBE. Vitreous injections of antibiotics were administered to both of his eyes. His right eye became affected by phthisis bulbi, but the condition in his left eye subsided, leaving a scarred lesion near the macula. However, complete retinal detachment occurred in his left eye approximately 10 months after the vitreous injection. During vitreous surgery, proliferative membrane formation was observed in the posterior pole area, and an irregular retinal break was detected in the scar margin caused by the traction of the proliferative membrane. After vitreous surgery, the retina was reattached under silicone oil. Conclusion: In cases of EBE, even if the inflammation has previously subsided, strict follow-up examinations are necessary, since complications such as rhegmatogenous retinal detachment may occur at a late stage.

Purpose. To study the effectiveness of extrascleral filling (ESF) using endoillumination in the surgical treatment of patients with primary rhegmatogenous retinal detachment (RRD). Material and methods. The material for the study was the data of a comprehensive clinical examination and surgical treatment by ESF method using endoillumination in 17 patients (17 eyes) with RRD. In 7 cases (41%), the macular area was involved in the detachment process. In 5 cases (29.4%), local scleral filling was performed. In the remaining 12 cases (70.6%), the local ESF was supplemented with a circling silicone element. Surgical intervention was supplemented by transscleral drainage of subretinal fluid (SRF) in 10 cases (59%) and pneumatic retinopexy with SF6 gas 50% in 8 cases (48%). Results. In the general group of patients, best corrected visual acuity (BCVA) increased from 0.35 to 0.46. In the subgroup of patients with a detached macular area, the positive dynamics is more pronounced, BCVA increased from 0.1 to 0.28. The progression of proliferative vitreoretinopathy caused the recurrence of retinal detachment in two patients (11.8%). Recurrences were diagnosed after 3 and 5 months, respectively. In both cases, a vitrectomy with tamponade of the vitreous cavity with silicone oil 5000 Cst was performed. The percentage of successful anatomical outcome after the first operation in our study was 82%. The percentage of successful achievement of the final anatomical result was 94%. In two cases, additional injection of SF6 gas into the vitreous cavity was required. Conclusion. This type of surgical treatment is an effective method of surgical treatment of patients with RRD. In our study, the successful anatomical outcome after the first operation was recorded in 82% of patients, which correlates with the data of the authors who also used this method (83–92%). Surgeons who performed surgical treatment using this technique in our study note improved workplace ergonomics when visualizing the fundus using an operating microscope and endoillumination compared with indirect ophthalmoscopy. Other teams of authors came to this conclusion as well. In our study, there were no complications associated with the introduction of a light pipe into the vitreous cavity (iatrogenic crystalline lens injury, endophthalmitis), which indicates the safety of this type of surgical treatment.

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.

And Chemical Properties

Silicone oils are polymer structures including siloxane repeats in the center. Copolymers formed by combining these polymers at different ratios constitute different silicone structures with different physical and chemical properties. The presence of several factors such as trauma, giant retinal tear, proliferative vitreoretinopathy and retinal tear in posterior localization is the main medical indications for the use of silicone oils in the surgery of rhegmatogenous retinal detachment. Problems associated with the need for a second surgical intervention to remove silicone oil, the emulsification of silicone oil with the problem this emulsification, and the presence of foreign structure in eye globe are the most important conditions limiting the use of silicone oil.

Purpose To report case of retinitis pigmentosa in association with rhegmatogenous retinal detachment. Methods An eight year old boy complained of a sudden visual loss. The patient had night blindness, bone spicule-like hyperpigmentation, pale optic disc in both eyes, and the retina was totally detached in the right eye. Results He was initially treated with conventional scleral buckling surgery, then pars plana vitrectomy with silicone tamponade was performed and retinal reattachment was established. After the phacoemulsification combined with silicone oil removal the final visual acuity of counting fingers was obtained. Conclusions The association of retinitis pigmentosa and rhegmatogenous retinal detachment is uncommon in young patients.
