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.

Purpose To describe a case series including 4 patients undergoing direct transretinal aspiration of subfoveal perfluorocarbon liquid (PFCL) and internal limiting membrane (ILM) peeling after macula-off retinal detachment surgery. Methods Four patients who had undergone vitreoretinal surgery due to primary rhegmatogenous retinal detachment were further treated because of retained subfoveal PFCL. Direct transretinal aspiration of PFCL through a self-sealing foveal retinotomy was performed in all cases using a 41-G needle placed on the top of the bubble. The ILM was peeled off prior to and after PFCL removal in 2 cases, respectively. Optical coherence tomography (OCT) scans were obtained preoperatively and postoperatively to assess the status of the macula. Results Subfoveal PFCL was successfully removed in all cases. Two patients had silicone oil tamponade at the time of the second surgery, which was temporarily removed in both cases and then reapplied in one. Best-corrected visual acuity improved in all cases. No postoperative macular hole was observed by OCT. Conclusions Direct transretinal aspiration of subfoveal PFCL with a 41-G cannula combined with conventional ILM peeling is a safe and effective technique to avoid long-term damage to the retinal layers with good functional outcomes. Performing the ILM peeling immediately before or after the PFCL aspiration does not seem to influence anatomic results.

Silicone Oil Tamponade

Purpose: Assess changes on spectral domain optical coherence tomography (OCT) before, during, and after removal of silicone oil (SO). Methods: Retrospective series of patients who underwent SO tamponade for macula-on rhegmatogenous retinal detachment. OCT scans of the affected eye were taken before, during, and 3 months after SO tamponade. Qualitative assessment of foveal contour and quantitative comparison of OCT parameters (central macular, cube, ganglion cell layer [GCL], and outer retinal thicknesses) were done between 3 time points. Results: Ten eyes of 9 patients were included. Flattening of the foveal contour during SO tamponade was completely reversed after SO removal. Average cube and GCL thicknesses decreased with SO tamponade and increased after SO removal ( P = .01 and P = .02, respectively). Outer retinal thicknesses did not vary among 3 time points ( P = .09). Conclusions: SO tamponade causes foveal flattening and thinning of the inner retinal layers, which is reversible on removal.
