Analysis Of Results

Purpose. Analysis of functional and anatomical results surgical treatment of retinal detachment and macular hole (RDMH) with internal limiting membrane (ILM) peeling and silicone tamponade. Material and methods. Analysis of results surgical treatment of 17 patients (17 eyes) with RDMH was carried out. Disease duration ranged from 2 weeks to 3 months. Visual acuity before surgical treatment ranged from no light perception to 0.05 (on average 0.01±0.02). All patients underwent endovitreal surgery with ILM removal. Then retinal holes were localized at periphery with further endolaser coagulation or cryocoagulation and silicone oil (5700 cSt) tamponade. Results. Retinal adhesion was noted in all eyes after primary surgery. Closure of hole was successful in 16 patients. After operation, visual acuity improved in all patients, averaging 0.11±0.09. Conclusion. Vitrectomy with IPM removal and silicone oil (5700 cSt) tamponade in treatment of RDMH made it possible to achieve reattachment of retina in 17 patients, complete closure of macular hole in 16 of 17 patients. One patient, according to optical coherence tomography, showed decrease diameter of macular hole after 12 months. Positive functional effect was achieved in increase visual acuity to average of 0.15±0.15 after 12 months.

Analysis Of Results

Purpose. Analysis of results of inverted internal limiting membrane (ILM) flap technique using 3D visualization for surgical treatment of macular holes (MH). Material and methods. 21 people with stage 3 or 4 MH. Visometry and optical coherence tomography (OCT) were performed before surgery, on the 3rd day and 1 month after surgery. All patients underwent a three-port 27G vitrectomy with using NGENUITY 3D visualization system (Alcon, USA). After vitrectomy and ILM staining, the ILM flap was formed in the form of single monoblock with wide base, which was turned over and placed on the MH area. The operation was completed by fluid/air exchange. Results. MH closure on the 3rd day after surgery was observed in 19 (90.5%) of 21 patients. In 2 patients, MH closure was absent; in these cases, a second operation was performed with silicone oil tamponade. One month after the operation, according to OCT datas, complete MH closure was noted in all patients. The average value of the best corrected visual acuity by this observation period was 0.3, which was 6 times higher than the initial (0.05) visual acuity. The use of 3D visualization system allowed us to reduce the level of endoillumination by up to 15% and to reduce the exposure time of the endovitreal dye to 15 seconds to reduce the risks of retinal phototoxicity. Conclusion. The proposed inverted ILM flap technique made it possible to achieve MH closure in 90.5% of cases. The experience of using NGENUITY 3D visualization system has shown high efficiency and safety by reducing the risk of iatrogenic phototoxicity.

Morphofunctional Analysis

Purpose. To evaluate the role of microperimetry and optical coherence tomography (OCT) in the morphofunctional analysis of the retina after surgical treatment of idiopathic macular holes (IMH). Materials and methods. A retrospective study of 33 patient's treatment results (33 eyes) with IMH was carried out. All patients underwent minimally invasive with 25G or 27G vitrectomy. Best corrected visual acuity (BCVA), macular photosensitivity, fixation stability, macular neuroepithelial (NE) volume and minimal macular hole diameter were analyzed. Follow-up period: 6 months. Results. A complete closure of the macular hole was achieved in all cases post-op. The patients had reliable improvement of BCVA, retinal photosensitivity and decrease of macular NE volume. Based on a multifactor correlation analysis with the purpose to predict the results of surgical treatment, the dependence of post-op BCVA on the pre-op photosensitivity of the retina and the minimal diameter of the macular hole was revealed. Conclusions. Microperimetry and OCT are modern non-invasive research methods allowing to estimate anatomical and functional results of surgical IMH treatment. The study of retinal photosensitivity in the macula and minimal macular hole diameter pre-op allows to predict post-op BCVA, which has a practical importance.

A 61-year-old Japanese woman presented with impairment of her left vision due to macular schisis secondary to branch retinal vein occlusion. Her left vision was 20/50, and schisis was observed inferotemporally. She underwent phacoemulsification and aspiration, implantation of the intraocular lens, and removal of the epiretinal membrane and internal limiting membrane. Her visual acuity stabilized ~20/50 for two and a half years after the initial surgery. However, she developed macula-involving retinal detachment, and her visual acuity declined to counting fingers. She underwent pars plana vitrectomy and removal of the residual vitreous cortex together with the inner retina within the area of vein occlusion. After the removal of silicone oil and the addition of an encircling buckle, the retina remained attached and visual acuity improved to 20/60 at one year after the final surgery. The combination of rhegmatogenous and tractional detachment in the area of schisis was suspected, and vitrectomy with inner retinectomy was effective.

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.
