ABSTRACT
PURPOSE: To identify the predictors for anatomical and functional outcome after re-vitrectomy with application of autologous platelet concentrate (APC) in eyes with persistent idiopathic macular hole (MH). METHODS: Retrospective study of 103 eyes with persistent MHs after vitrectomy with peeling of internal limiting membrane (ILM) and expansive gas. All patients underwent re-vitrectomy with APC and endotamponade. The anatomical MH closure rate and postoperative best-corrected visual acuity (BCVA) were evaluated. Further, predictive factors influencing the success of the surgery were analyzed. RESULTS: Median BCVA (logMAR) before the surgery was 1.00 (interquartile range [IQR] 0.80-1.30) and the median of minimum diameter between hole edges was 508 µm (IQR 387-631). The final closure rate after re-vitrectomy with APC was 60.2% (62 of 103 eyes). The following predictors were identified to significantly influence the closure rate: tractional hole index (THI), axial length, time between first and second surgery, and the experience of the surgeon (p < 0.05). CONCLUSIONS: Re-vitrectomy with APC led to the closure of 60.2% of the persistent MHs. The closure rate negatively correlates with increasing axial length, time between the first and second surgery, and the decreased THI. Further, experienced surgeons (with a history of >100 pars plana vitrectomies with ILM peeling) had significantly higher closure rates.

Several factors predispose to the occurrence of rhegmatogenous retinal detachment, including cataract surgery, myopia, and degenerative lesions of the peripheral retina as well as eye trauma. This study aims to compare the anatomical and functional outcome of the two surgical techniques (AB interno vs AB externo) in our Hospital. We conducted a descriptive, retrospective study in the Department of Ophthalmology at the University Hospital Mohamed VI in Marrakech, over a period of 3 years, ranging from January 2013 to December 2015. During the study period we compared two groups of people: the first group undergoing surgery by an external approach (cryoapplication of the dehiscences with episcleral indentation) while the second undergoing surgery by endo-ocular approach. Group A or AB externo group included 26 eyes (26 patients) while Group B or vitrectomy with internal tamponade group included 22 eyes (22 patients). In the AB externo group, the average age was 54.92 years against 51.64 years in the AB interno group, with a slight predominance of males in both groups. After the first surgery, retinal reapplication was obtained in both groups with no significant difference, (about 80.76% in Group A versus 81.82% of the second group). In both groups failure was caused advanced vitreoretinal proliferation (4 cases), de novo breaks (3 cases) and breaks which had not been detected on first examinations (2 cases). All these cases underwent reoperation by AB interno approach: patients of group A underwent complete vitrectomy with revision of the indentation +/- internal limiting membrane peeling with internal gas tamponade while patients of group B underwent complementary vitrectomy with dissection of proliferative vitreoretinopathy (PVR) and an internal tamponade with silicone oil. After a mean follow-up period of 12 months, there was no significant difference in visual acuity between the 2 groups, with more than one third of the patients who had regained visual acuity between 1/10 and 5/10 (about 34,61% in AB externo group and 36,36% in AB interno group). Given the technological advances in vitrectomy, the current trend is the endo-ocular surgery however ab-externo surgery is mainly used in the treatment of retinal detachment with visible breaks which can be easily treated with indentation without advanced vitreoretineal proliferation (PVR A-B).

PURPOSE: To evaluate the outcomes of pars plana vitrectomy with silicone oil tamponade in the management of retinal detachment associated with giant retinal tears. METHODS: We reviewed 45 eyes of 42 patients with primary retinal detachment associated with giant retinal tears over 10 years at a tertiary referral centre. Patients underwent 23-gauge vitrectomy without adjuvant scleral buckling by a single surgeon and had follow-up at least 6 months after silicone oil removal. RESULTS: Mean follow-up was 37 ± 35 months. Seven eyes (16%) had grade C proliferative vitreoretinopathy, and 16 (36%) had a giant retinal tear ≥180° at baseline. The primary reattachment rate was 84%, and the overall final anatomical success rate was 98%. The mean Snellen visual acuity equivalent at the final visit was 20/58. Final visual acuity ≥20/40 was achieved in 64%. The mean duration of silicone oil tamponade was 10.5 ± 4 weeks. By the final visit, silicone oil had been removed from 44 eyes (98%). CONCLUSION: The high rates of anatomical and functional success support management of giant retinal tears-associated retinal detachment with vitrectomy without adjuvant scleral buckling. Removal of silicone oil at the earliest possible time helps to avoid complications such as keratopathy, glaucoma and visual loss without apparent reason.

BACKGROUND: Septal surgery is a well-established procedure used to treat nasal obstruction due to deviation of the nasal septum, which is carried out under local or general anaesthesia. Local anaesthesia is used for postoperative pain control, but its effectiveness and safety are unclear. OBJECTIVES: To assess the effectiveness of perioperative local anaesthesia for reducing pain in septal surgery and to evaluate the risk of associated complications. SEARCH METHODS: The Cochrane ENT Information Specialist searched the Cochrane ENT Trial Register; Central Register of Controlled Trials; Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 9 January 2018. SELECTION CRITERIA: Randomised controlled trials and cluster-randomised controlled trials involving adults or children (or both) who underwent septal surgery. We included studies comparing local anaesthesia versus no treatment/placebo. We also included studies comparing different types of local anaesthesia to each other (i.e. local injection, the addition of an anaesthetic agent to nasal packing, where used, and sphenopalatine ganglion block). DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. The primary outcome was postoperative pain intensity at 12, 24 and 48 hours measured by visual analogue scale (VAS) or another pain outcome tool including numerical or verbal rating scales. Secondary outcomes were requirement for additional analgesia, duration of hospitalisation and adverse effects (postoperative bleeding and postoperative vomiting). We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. MAIN RESULTS: We included seven randomised controlled trials involving 493 participants. In all studies the participants were adults undergoing septoplasty. These studies were heterogeneous and the quality of the body of evidence ranged from low to very low. Few of the studies provided reliable data for the primary outcome in this review.Local anaesthetic injection versus no treatment/placeboTwo studies (142 participants) compared local anaesthetic injection versus placebo but these studies did not report postoperative pain at 12, 24 or 48 hours. It is unclear whether local anaesthetic injection changed the risk of vomiting (odds ratio (OR) 3.10, 95% confidence interval (CI) 0.12 to 79.23; 60 participants; one study) (low-quality evidence). Neither study reported the requirement for additional analgesia, duration of hospitalisation or uncontrollable postoperative bleeding.Local anaesthetic application via nasal packing versus no packing/packing with placeboFour studies (301 participants) used nasal packing postoperatively and compared the addition of local anaesthetic to the pack versus packing with a placebo added. Compared with packing with placebo, the addition of local anaesthetic to nasal packing reduced the pain score on a VAS (ranging from 0 to 100) at 12 hours (mean difference (MD) -16.95, 95% CI -22.27 to -11.62; 151 participants; two studies; I2 = 49%) (low-quality evidence) and at 24 hours postoperatively (MD -7.53, 95% CI -9.76 to -5.29; 268 participants; four studies; I2 = 83%) (very low-quality evidence). These studies did not report postoperative pain at 48 hours. The addition of local anaesthetic to nasal packing decreased the requirement for additional analgesia (OR 0.15, 95% CI 0.07 to 0.34; 151 participants; two studies; I2 = 15%) (moderate-quality evidence). No studies reported duration of hospitalisation, postoperative vomiting or uncontrollable postoperative bleeding.No studies compared the addition of local anaesthetic to nasal packing versus no packing.Sphenopalatine ganglion block versus no treatment/placeboOne study (50 participants) compared sphenopalatine ganglion block versus no treatment but this study did not report postoperative pain, requirement for additional analgesia, duration of hospitalisation, vomiting or uncontrollable postoperative bleeding. AUTHORS' CONCLUSIONS: The addition of local anaesthesia to nasal packs (if these are being used) following septal surgery may reduce postoperative pain within the first 12 hours, compared to nasal packing with a placebo added. The effect is uncertain at 24 hours because the quality of the evidence is very low. Evidence was lacking for other outcomes, including adverse effects. There is a lack of evidence about the effects of local anaesthesia added to nasal packing compared to no nasal packing. There is also a lack of evidence about the effects of local anaesthesia given by injection and the effects of sphenopalatine ganglion block.

BACKGROUND: We planned a three arm randomized study to evaluate the safety and efficacy of a new blood stopper, Ankaferd blood stopper (ABS) along with short-time compression, compared to either short-time compression with conventional sterile gauzes (CSG) or with a TR band after transradial (TRA) procedures. METHODS: The Ankaferd blood stopper as a new strategy to avoid early complications. After transradial procedures (ABS transradial) trial is designed in a prospective, randomized, placebo-controlled fashion and registered with http://clinicaltrials.gov (NCT02982733). Six hundred and thirty patients were randomized into three arms in a 1:1:1 fashion corresponding to three different strategies of patent hemostasis techniques after diagnostic or interventional catheterization. RESULTS: One (0.49%) patient in the CSG group and one patient (0.48%) in the TR Band group developed RAO at the end of the hemostasis, compared with 0 (0%) in the ABS group. At 30 days follow-up none of the groups had any patients with RAO. As a secondary end-points the difference was not statistically significant regarding hematoma among the three groups (P = 0.70). Bleeding during deflation of the TR Band or removal of the elastic bandage occurred in 55 patients (26.96%) in the CSG group and in 56 (27.31%) patients in the TR Band group compared to 19 patients (9.40%) in the ABS group (P < 0.001). CONCLUSION: Ankaferd blood stopper is a promising device for use in patent hemostasis, with no evidence on RAO at short-term or long term and with reduced risk of re-bleeding at the end of hemostasis.

PURPOSE: To evaluate long-term outcome after revitrectomy with autologous platelet concentrate (APC) or whole blood (WB) in persistent idiopathic macular hole (MH) after vitrectomy with internal limiting membrane (ILM) peeling. PROCEDURES: Retrospective study of 75 eyes with persistent MH after vitrectomy with ILM peeling and gas. All patients underwent revitrectomy with gas and APC (n = 61) or WB (n = 14). Main outcome measures were anatomical closure rate and postoperative best-corrected visual acuity (BCVA). RESULTS: Closure rate after revitrectomy was 85.2% (52/61) in the APC group and 7.1% (1/14) in the WB group. Median follow-up was 58 (range 3-147) months. Median BCVA (logMAR) in patients with finally closed MHs was 0.4 ± 0.3. Patients with defects of the ellipsoid zone had significantly worse postoperative BCVA. Morphological MH configuration (atrophic or elevated edges) did not correlate with final closure rate. CONCLUSIONS: Revitrectomy with APC and gas is a very effective treatment in persistent MH after vitrectomy with ILM peeling and gas.

Background Proliferative vitreoretinopathy (PVR) occurs in 10â% of patients with retinal detachment and is characterized by excessive epi-, sub- or intraretinal contraction. Corticosteroids have been shown to counter this contraction. Patients and Methods Retrospective review of 5 patients (3 females, 2 males) with recurrent retinal detachment with stage C PVR. The mean age was 61.2 ± 20.5 years and myopia > - 5.0 dioptres was present in 3 eyes. Patients were treated with 23 g vitrectomy, retinectomy and endolaser, dexamethasone (Ozurdex®) injection under perfluorocarbone and 5500 cs silicone oil tamponade. Results After a total follow-up of 8.8 ± 6.4 months with silicone oil tamponade, the Ozurdex® implant was localised in the macula in 1 case, and in 4 cases behind the iris with a completely attached retina. Preoperative intraocular pressure was 11.0 ± 4.0 mmHg, which remained stable at 7.8 ± 3.5 mmHg at the end of the final follow-up. No localised adverse effects were observed of the implant on the retina or the iris. Conclusions The dexamethasone implant Ozurdex® is well tolerated in conjunction with silicone oil tamponade in eyes with retinal detachment and PVR. The implant may be a potential candidate for the prevention of PVR.

OBJECTIVE: To study the outcome of the treatment of complex rhegmatogenous retinal detachments (RRDs). DESIGN: Nonrandomized, multicenter, retrospective study. PARTICIPANTS: One hundred seventy-six surgeons from 48 countries spanning 5 continents reported primary procedures for 7678 RRDs. METHODS: Reported data included clinical manifestations, the method of repair, and the outcome. MAIN OUTCOME MEASURES: Failure of retinal detachment repair (level 1 failure rate), remaining silicone oil at the study's conclusion (level 2 failure rate), and need for additional procedures to repair the detachments (level 3 failure rate). RESULTS: The main categories of complex retinal detachments evaluated in this investigation were: (1) grade B proliferative vitreoretinopathy (PVR; n = 917), (2) grade C-1 PVR (n = 637), (3) choroidal detachment or significant hypotony (n = 578), (4) large or giant retinal tears (n = 1167), and (5) macular holes (n = 153). In grade B PVR, the level 1 failure rate was higher when treated with a scleral buckle alone versus vitrectomy (P = 0.0017). In grade C-1 PVR, there was no statistically significant difference in the level 1 failure rate between those treated with vitrectomy, with or without scleral buckle, and those treated with scleral buckle alone (P = 0.7). Vitrectomy with a supplemental buckle had an increased failure rate compared with those who did not receive a buckle (P = 0.007). There was no statistically significant difference in level 1 failure rate between tamponade with gas versus silicone oil in patients with grade B or C-1 PVR. Cases with choroidal detachment or hypotony treated with vitrectomy had a significantly lower failure rate versus treatment with scleral buckle alone (P = 0.0015). Large or giant retinal tears treated with vitrectomy also had a significantly lower failure rate versus treatment with scleral buckle (P = 7×10(-8)). CONCLUSIONS: In patients with retinal detachment, when choroidal detachment, hypotony, a large tear, or a giant tear is present, vitrectomy is the procedure of choice. In retinal detachments with PVR, tamponade with either gas or silicone oil can be considered. If a vitrectomy is to be performed, these data suggest that a supplemental buckle may not be helpful.

PURPOSE: To evaluate the tamponade effect on the retina of a heavier-than-water silicone oil mixture and to compare it with the effect of silicone oil. METHODS: Prospective, non-randomised, comparative pilot study. Phakic/pseudophakic patients with retinal detachment undergoing vitrectomy with Densiron 68 or silicone oil were recruited. The 'separation volume', defined as the relative volume of the space between intraocular tamponade agent and retina, was estimated using magnetic resonance imaging in both groups and compared. RESULTS: Nine participants were included; 4 received silicone oil and 5 Densiron 68. The mean separation volume was statistically significantly larger in the silicone oil group (0.477 ± 0.419 cm(3)) than in the Densiron group (0.042 ± 0.013 cm(3); p = 0.014). CONCLUSIONS: In this study Densiron achieved an excellent tamponade effect in the retina.

PURPOSE: To compare the anatomical and functional outcomes of 23-gauge pars plana vitrectomy (PPV) with Densiron-68 tamponade and 360° endolaser versus 20-gauge PPV with encircling scleral buckling (ESB) and an SF6 gas tamponade for the repair of primary pseudophakic retinal detachment with inferior retinal breaks. METHODS: Prospective, randomized, comparative, interventional study. Eighty-two eyes of 82 consecutive patients were randomly assigned to 1 of the 2 treatment groups: 23-gauge PPV/Densiron-68 (44 eyes, 54%) or 20-gauge PPV/ESB/SF6 (20%) (38 eyes, 46%). The inclusion criterion was the presence of primary pseudophakic retinal detachment with at least 1 retinal break between the 4- and 8-o'clock positions. The study protocol involved a minimum of 7 visits: baseline, day of surgery, 1 week, and 1, 3, 6, and 9 months postoperation. Densiron-68 removal was performed within 12 weeks of the initial surgery. Two surgical procedures were required in the Densiron group to remove the oil. RESULTS: After the primary procedure, the retina was reattached in 90% (40 of 44) of cases in the 23-gauge PPV/Densiron group and in 92% (35 of 38) of cases in the 20-gauge PPV/ESB/SF6 group (P = 0.2, Fisher's exact test). After resolution of redetachments, final anatomical success rate rose to 97% (43 of 44) in the 23-gauge PPV/Densiron group and 94% (36 of 38) in the 20-gauge PPV/SB/SF6 group (P = 0.32, Fisher's exact test). Mean final best-corrected visual acuity (logarithm of the minimum angle of resolution) was 0.40 in the 23-gauge PPV/Densiron group and 0.48 in the 20-gauge PPV/ESB/SF6 group (P = 0.31, t-test). Operative time was significantly less in the 23-gauge PPV/Densiron group (P = 0.002, t-test). No statistically significant difference in the complication rate between the two groups was recorded. CONCLUSION: Twenty-three-gauge PPV combined with Densiron-68 and 360° endolaser and 20-gauge PPV combined with ESB/SF6 seemed to have similar efficacy in the repair of primary pseudophakic retinal detachment. Supplementary scleral buckling can be avoided using a Densiron-68 tamponade for retinal detachment with inferior retinal breaks.
