Orbital Gas after 25-Gauge Pars Plana Vitrectomy with Incorrect Gas Mixture.

ABSTRACT: We present 2 cases of sutureless 25-gauge pars plana vitrectomy and fluid-gas exchange, in which incorrect gas concentrations likely led to elevated intraocular pressures and retrobulbar gas. Combined removal of orbital gas with anterior orbitotomy and pars plana vitrectomy was performed in the first case to address expanding intraocular and retrobulbar gas resulting from a suspected error in gas dilution. Vitreous and orbital gas removal by needling was effective in the second case. In patients with elevated intraocular pressure and orbital gas accumulation after vitrectomy, combined intraocular and orbital decompressions were effective in optimizing clinical outcomes. There is no consensus regarding the best management of orbital gas after vitrectomy. We propose that a multidisciplinary technique should be considered, when available.

25-Gauge pars plana vitrectomy combined with air tamponade for primary rhegmatogenous retinal detachment.

Project description:ObjectiveThis study was performed to evaluate the outcomes of 25-gauge (25-G) pars plana vitrectomy (PPV) with air tamponade for primary rhegmatogenous retinal detachment (RRD).MethodsThis retrospective consecutive case series included 126 eyes of 125 patients with primary RRD who underwent 25-G PPV with air tamponade. The patients were followed up for at least 6 months following surgery. The main outcome measures were the primary and final anatomical success rates and postoperative complications.ResultsThe mean age of the 125 patients (80 men and 45 women) was 53.7 ± 10.0 years. The mean follow-up period was 8.3 ± 2.2 months (range, 6-18 months). Twenty-four eyes (19.0%) presented with high myopia, and 13 eyes (10.3%) were pseudophakic. Of the 126 eyes, 37 (29.4%) had inferior breaks, 2 (1.6%) had choroidal detachment, and 86 (68.3%) had macular detachment. The single- and final-operation success rates were 96.0% and 100%, respectively. Postoperative complications included macular hole formation in two eyes. During follow-up, secondary cataract surgery was performed in 27 (23.9%) of the 113 phakic eyes.Conclusion25-G PPV with air tamponade is effective and safe in treating selected patients with primary RRD with a high anatomical success rate.

Clinical outcomes of a beveled tip, ultra-high speed, 25-gauge pars plana vitrectomy system.

Project description:ObjectiveTo report the clinical outcomes of a 25-gauge, beveled-tip, 10,000 cuts-per-minute (cpm) microincisional vitrectomy surgery (MIVS) system.MethodsProspective case series of eyes undergoing primary pars plana vitrectomy (PPV) for common vitreoretinal indications. Main outcome measures were: rate of achieving surgical objectives, operative times, number of surgical steps, use of ancillary instruments, corrected distance visual acuity (CDVA), and adverse events (AE).ResultsThe surgical objectives were achieved in all eyes. Mean total operative time (TOT), core, shave and total vitrectomy times were 1891 ± 890, 204 ± 120, 330 ± 320, 534 ± 389 s, respectively. Mean number of surgical steps was 4.3 ± 1.5. Mean number of ancillary instruments used was 4.5 ± 1.9. Mean CDVA improved by 0.53 ± 0.56 logMAR units (P < 0.001) 3 months postoperatively. AE included elevated IOP (8%), hypotony (6%), and re-detachment (2%). Majority (82%) had no postoperative discomfort. The number of surgical steps demonstrated a positive correlation with TOT (p < 0.05), number of ancillary instruments used (p < 0.05), and postoperative Day 1 IOP (p < 0.05). The number of times ancillary instrumentation was used demonstrated a positive correlation with TOT (p < 0.05).ConclusionBeveled-tip, 10,000 cpm MIVS system effectively and safely performs common VR procedures of varying complexity and may reduce operative times and use of ancillary instrumentation.

Air Tamponade for Rhegmatogenous Retinal Detachment With Inferior Breaks After 25-Gauge Pars Plana Vitrectomy: Technique and Outcome.

Project description:To evaluate the outcomes of 25-guage (G) pars plana vitrectomy (PPV) with air tamponade for rhegmatogenous retinal detachment (RRD) with inferior breaks. This retrospective consecutive case series included fifty-two eyes of fifty-two RRD patients with inferior breaks who underwent 25-G PPV with air tamponade. These patients were followed up for at least 6 months following surgery. Primary and final anatomical success rates and postoperative complications were the main outcome measures. The mean age of the patients (39 men and 13 women) was 51.8 ± 11.8 years. There were 49 primary RRDs (94.2%) and three recurrent RRDs (5.8%). The mean follow-up period was 8.2 ± 1.6 months (range: 6-13 months). Sixteen eyes (30.8%) presented with high myopia, and six eyes (11.5%) were pseudophakic. Proliferative vitreous retinopathy grade was C1 in four eyes (7.7%). Of the 52 eyes, two (3.8%) were complicated with choroidal detachment, and forty (76.9%) had the macula detached. The single- and final-operation success rates were 96.2% and 100%, respectively. During follow-up, secondary cataract surgery was performed in eight eyes (17.4%) of the 46 phakic eyes. 25-G PPV with air tamponade is effective in treating selected RRD patients with inferior breaks. Patients can benefit from early visual recovery and less complications.

Surgical Outcomes of 27-Gauge Pars PLana Vitrectomy for Symptomatic Vitreous Floaters.

Project description:PurposeTo report the surgical outcomes of 27-gauge pars plana vitrectomy (PPV) for symptomatic vitreous floaters.Methods47 eyes of 47 patients (39 males, 83.0%) with symptomatic vitreous floaters who underwent 27-gauge PPV and followed up for more than 6 months were included. The mean age was 34.7 ± 13.5 years.ResultsNo operative complication occurred. At first day postoperatively, the intraocular pressure (IOP) was significantly lower than that at other time points (8.6 ± 2.7 mmHg, p < 0.001). 28 (59.6%) eyes had transient hypotony (IOP < 8 mmHg). All were recovered within 1 week postoperatively. The BCVA of 41 eyes (41/47, 87.2%) remained unchanged or improved. Postoperative complications occurred in two eyes: one (2.1%) had endophthalmitis and one (2.1%) had retinal detachment. No clinical significant cataract was observed in the 42 postoperative phakic eyes. 91.5% of the patients were satisfied with the surgery outcome. Besides, 91.3% of the patients felt that the floaters were removed completely or only had an acceptable residual.ConclusionVisual acuity of most patients remained unchanged or improved following 27-gague pars plana vitrectomy for symptomatic vitreous floaters, resulting in high patient satisfaction. However, this treatment should be performed with great caution since severe postoperative complications may still occur. This trial is registered with NCT03049163.

Dynamic angle closure following pars plana vitrectomy with perfluoropropane gas.

Project description:PurposeTo report the clinical course of an aphakic patient who developed positional secondary angle closure glaucoma following pars plana vitrectomy (PPV) with perfluoropropane (C3F8) gas tamponade.ObservationsA 23-year-old male presented due to a two-year history of vision loss in the left eye. Best-corrected visual acuity (BCVA) was 20/200 and intraocular pressure (IOP) was 12 mm Hg OS. Exam revealed iridodonesis and aphakia of both eyes, and a total RRD in the left eye. The patient underwent scleral buckle plus PPV with 15 % C3F8 gas and was instructed to maintain face-down positioning for 5 days. On post-operative day 1, IOP was 32 mm Hg and exam revealed significant diffuse corneal edema, a large epithelial defect, and 85 % C3F8 fill of the vitreous cavity. Patient was started on IOP-lowering drops but continued to have elevated IOP and corneal epithelial sloughing over the next 3 weeks. He was taken for a superficial keratectomy, but when placed supine under the microscope, a large new gas bubble was visualized overlying the pupil in a now shallow anterior chamber (AC) and IOP was 52 mm Hg. The patient was positioned back upright and the gas bubble migrated posteriorly out of the AC with return of IOP to 25 mm Hg. The dynamic nature of his IOP raised concerns for intermittent angle closure by C3F8 induced by supine positioning. Thus, a pars plana aspiration of the C3F8 gas was performed and resulted in normalization of the IOP.Conclusions and importanceDynamic, positional secondary angle closure glaucoma can occur after vitrectomy with C3F8 in the setting of aphakia. This is the first report to capture C3F8 gas migration causing intermittent acute angle closure in real-time. Due to its intermittent nature however, the diagnosis may not be initially apparent at the slit lamp. Thus, we suggest this potential complication should be carefully monitored for and discussed when advising post-vitrectomy positioning in aphakic patients.

Obtaining undiluted vitreous sample using small gauge pars plana vitrectomy and air infusion.

Project description:Vitreous biopsy is essential for establishing a definitive diagnosis and guiding potential therapy in patients with refractory vitritis and posterior uveitis, among other indications. Especially in cases where one must rule out intraocular lymphoma, obtaining a significant amount of undiluted vitreous increases diagnostic yield. We demonstrate our technique for obtaining a significant amount of undiluted vitreous using pars plana vitrectomy with air infusion.

Air versus fluorinated gas tamponades in pars plana vitrectomy treatment for primary rhegmatogenous retinal detachment.

Project description:PurposeTo compare the treatment success of air with fluorinated gas (20% SF6 or 14% C3 F8 ) tamponade in pars plana vitrectomy for primary rhegmatogenous retinal detachment.MethodsA retrospective cohort study comprised of 1023 consecutive primary retinal detachment cases between 2014 and 2020. We employed a univariate multivariable binary logistic regression model.ResultsWe used intraocular gas tamponades in 872 cases with PVR grade B or lower: air tamponade was used in 414 eyes and 458 eyes were treated with a type of fluorinated gas tamponade. There was no significant difference in the type of tamponade with regard to the re-detachment rate (95% CI -1.0% and 4.1%). Additionally, also in the subgroup of rhegmatogenous retinal detachments with inferior located retinal defects we found no significant difference between the two types of tamponade (p = 0.54 Fisher's exact). The multivariable model, which included tamponade, PVR grade, a retinal detachment involving the 6 o'clock position and age as covariates, also showed no significant effect of tamponade choice on treatment success (OR 0.5, 95% 0.2-1.0, p = 0.10).ConclusionWe found no difference in treatment success with air tamponade versus fluorinated gas tamponades in the repair of primary retinal detachments, this also includes inferiorly located retinal tears and detachments.

Evaluation of intraocular gas using magnetic resonance imaging after pars plana vitrectomy with gas tamponade for rhegmatogenous retinal detachment.

Project description:We used magnetic resonance imaging (MRI) to assess how a patient's posture affects intraocular gas changes and whether the postoperative prone position is required after pars plana vitrectomy (PPV) with gas tamponade for rhegmatogenous retinal detachments (RRDs). Eight patients with RRDs who underwent PPV combined with cataract surgery with gas tamponade were prospectively included. They underwent MRI examination both in the prone and supine positions. We separated the retina into four parts: superior-posterior, superior-anterior, inferior-posterior, and inferior-anterior. We then calculated the gas contact rate as (the length of the retina contacting the gas in each retinal part) divided by (the length of each retinal part) × 100% in both the prone and supine positions. The mean gas contact rate of the superior-anterior part of the retina was significantly higher (P = 0.006) in the supine position than in the prone position. The mean gas contact rate of the inferior-anterior part of the retina was also significantly higher (P = 0.0004) in the supine position than in the prone position. We believe that if all retinal breaks were located anterior to the equator, the supine position may provide better tamponade gas coverage for the breaks than the prone position. Although potential postoperative complications caused by the supine position require careful attention, our result may shorten the duration of postoperative prone position and may decrease the patients' discomfort after PPV with gas tamponade for RRDs.

Binocular indirect ophthalmo microscope-assistant gas-perfused pars plana vitrectomy: A novel technique for vitreous sample acquisition.

Project description:The vitreous sample has been used for the diagnosis of uveitis and intraocular malignancy for decades. The sample volume is usually limited to 1 mL with current techniques. In the present study, a novel technique for higher amount of vitreous sample acquisition, that is, Binocular Indirect Ophthalmo Microscope-assistant gas-perfused pars plana vitrectomy (BAG-PPV) was invented.For diagnostic purpose, BAG-PPV with 23-ga vitrectomy system was performed on a 54-year-old Chinese male with the symptom of bilateral atypical uveitis. More than 3 mL of vitreous sample per eye was collected without any significant complications. Cytopathology was confirmed on the basis of cell surface markers and released cytokines by flow cytometry analysis and cytokine assays respectively.A monoclonal B-cell population with the pattern of CD5, CD10, cyKi67, CD71, FMC7, CD23, and kappa light chain single expression for the right eye and a monoclonal B-cell pattern with CD5, CD10, cyKi67, and kappa light chain restriction for the left eye were identified. The cytokine assay revealed high levels of interleukin (IL)-10 (90,838.30 and 41,098.0 pg/mL for the right and left eyes, respectively) and IL10/IL6 ratios for both eyes (with 90.78 and 63.26 for the IL10/IL6 ratios of the right and left eyes, respectively), while those for the cerebrospinal fluid were low (4.77 pg/mL for the IL10 level and 0.65 for the IL10/IL6 ratio). Based on the results, the patient was diagnosed with primary intraocular lymphoma for bilateral eyes.Our results demonstrated that diagnostic vitrectomy with BAG-PPV using the 23-ga vitrectomy system was safe, efficient, and able to provide useful diagnostic information for suspicious intraocular malignancy and other atypical uveitis.

A pilot study of pars plana vitrectomy, intraocular gas, and radial neurotomy in ischaemic central retinal vein occlusion.

Project description:BACKGROUND/AIMS:There is no effective treatment for ischaemic central retinal vein occlusion (CRVO). The two major negative outcomes are neovascular glaucoma (NVG) and severe central visual loss. In this study pars plana vitrectomy (PPV), mild panretinal photocoagulation, and intraocular gas injection were employed to prevent NVG. The potential role of incision of the lamina cribrosa (radial neurotomy) for visual recovery was examined. METHODS:Eight eyes of seven patients with ischaemic CRVO had PPV, mild panretinal photocoagulation, and intraocular perfluoropropane gas injection. Four eyes had radial neurotomies performed. The patients were examined by fundus photography, fundus fluorescein angiography, optical coherence tomography, and Goldmann visual field analysis. RESULTS:No patients suffered from neovascular glaucoma. Visual recovery was seen in patients with and without neurotomy but some patients had cataract extraction to allow visualisation for PPV. Fundus photography demonstrated reduced engorgement of retinal veins in two of the patients with neurotomy and one with PPV alone. Optical coherence tomography demonstrated macular oedema in three patients with neurotomy and all patients with PPV alone. Segmental visual field loss was seen in one patient with neurotomy suggesting damage to the optic nerve head. CONCLUSIONS:PPV is safe in ischaemic CRVO. Combined with mild PRP and intraocular gas injection the risk of neovascular glaucoma is low. Neurotomy can be added to try to improve the chances of recovery of central vision but may cause additional peripheral visual field loss.
