“…14 Mean sub-foveal choroidal thickness was significantly reduced following silicone oil tamponade and the choroidal thickness further decreased after silicone oil removal. 15 Similar results were generated in another study by Karimi et al which showed not just a decrease in choroidal thickness after silicone oil tamponade, but also a failure of the thinned out choroid to attain its preoperative thickness. 16 Interestingly, the degree of decrease in choroidal thickness was directly proportional to the duration of silicon oil tamponade.…”

Purpose: To evaluate the effect of silicone oil (SO) tamponade and its removal on central macular thickness (CMT) and average macular thickness (AMT). Study Design: Quasi experimental study. Place & Duration of Study: Jinnah Postgraduate Medical Centre, Karachi, from June 2021 to April 2022. Methods: A total of 27 patients with 27 eyes with rhegmatogenous retinal detachment were included. Pars Plana Vitrectomy (PPV) with SO tamponade was performed. Removal of silicon oil (ROSO) was performedafter six months. Optical Coherence Tomography (OCT) was done before PPV, one month after PPV and one month after ROSO. The Central macular thickness (CMT) and Average macular thickness (AMT) were measured and compared between operated and control eyes. Results: The mean CMT and AMT before surgery was 230 ± 60.5 μm and 253.3 ± 40.3 μm respectively. The mean CMT one month after PPV with SO was 281 ± 62.8 μm and 232 ± 62.2 μm in the operated eyes and control eyes (p = 0.053). Mean AMT one month after PPV with SO was 294 ± 98.7 μm and 253 ± 37.0 μm in operated and control eyes (p = 0.182). Mean CMT one month after SO removal was 222 ± 81.5 μm in operated eyes and 230 ± 59.2 μm in control eyes (p = 0.056). Mean AMT one month after SO removal was 263 ± 45.0 μm in operated eyes and 254 ± 21.4 μm in the control eyes (p = 0.087). Conclusion: There was no statistically significant difference in the CMT and AMT before and after silicone oil tamponade and its removal, in patients with Rhegmatogenous Retinal Detachment.

“…In this study, the mean BCVA before silicone oil removal was 0.75 LogMAR, but afterward, it improved to 0.69, 0.61, and 0.58 at 1, 4, and 8 weeks post SO removal, respectively. Similar results were found by Selim et al (2019), who assessed BCVA before and 8 weeks after removal; the BCVA was 0.05 dec and 0.05–0.8 dec, consecutively [ 29 ]. A study by Nassar et al (2019) also reported that 6 months or >6 months of SO application affected BCVA.…”

Rhegmatogenous retinal detachment (RRD) is a serious and emergency condition that may cause visual disturbance. Treatment includes pars plana vitrectomy with a tamponade such as intraocular gas or silicone oil (SO). In many countries, silicone oil is still favorable compared to intraocular gases as tamponade for reattachment of retinal detachment surgery. The application provides a higher anatomical success rate, especially in cases of proliferative vitreoretinopathy (PVR) that were previously considered untreatable. Objective assessment of the retinal nerve fiber layer (RNFL) using optical coherence tomography (OCT) in the eye with silicone oil tamponade is a challenge because of the limitations and difficulties in taking images. This study aims to assess the RNFL thickness changes in rhegmatogenous retinal detachment patients using SO tamponade and its subsequent removal conducted on a total of 35 post-operative RRD patients. Central macular and RNFL thickness, as well as best-corrected visual acuity (BCVA), were recorded at the time of tamponade and after the removal of the SO at 1, 4, and 8 weeks, respectively. The results showed that the changes in RNFL thickness significantly decreased in the group of ≤6 months, especially in the superior and temporal quadrants, and BCVA increased after SO removal (p < 0.05). Central macular thickness was significant (p < 0.001) at the end of the visit. Improved visual acuity is associated with decreased RNFL and central macular thickness after SO removal.

“…5 Furthermore, due to the potential adverse effects of silicone oil on the retina, gas use in appropriate cases emerges as an advantage factor. 10 The inventor of this surgical procedure, Tornambe, applied PR to 302 patients with RRD and achieved a success rate of 68% in a single surgical intervention and 95% with additional surgeries. 11 In a review conducted by Chan et al, the rate of PR efficacy in surgical success was found to be approximately 75%, ranging from 45% to 90%.…”

To reveal the factors affecting the surgical outcomes and pathological findings in the fellow eye in patients who underwent pneumatic retinopexy (PR) for rhegmatogenous retinal detachment (RRD). Material and Methods: Patients treated for RRD between 2014 and 2021 were evaluated retrospectively. The study included 43 eyes of 18 female and 25 male patients who underwent PR. Age, gender, best-corrected visual acuity (BCVA), lens status, number of preoperative tears, macular involvement, tamponade, intraocular pressure, and anatomic success were evaluated preoperatively and at the last visit. The fellow eye findings were also investigated. Results: Retinal reattachment was observed in 21/43 (48%) eyes. Macular involvement was present in 24 (55.8%) patients. The mean BCVA before surgery was 1.4±1.2 logarithms of minimum angle resolution (logMAR), and the mean BCVA at the final follow-up after surgery was 0.8±0.9 logMAR (p=0.003). Macular involvement, gas type (sulfur hexafluoride-perfluoropropane), lens status (phakic-pseudophakic), and the location of the tear quadrant (2 o'clock/10 o'clock) were not determined to affect the surgical success (p=0. 43, p=0.37, p=0.15, p=0.73, respectively). Surgical success increased to 85% at the 1-year follow-up with secondary procedures. Lattice degeneration was found in 3 (7%) patients, retinal detachment in 4 (9%) patients, and retinal tear in 2 (4%) patients in the fellow eye of RRD. Conclusion: Although PR is a cost-effective method in RRD treatment, an additional surgical procedure may be required during follow-up. Detailed evaluation of the fellow eye pathologies is critical to prevent RRD development.
