Investigation of scleral thermal injuries caused by ultrasonic pars plana phacoemulsification and aspiration using pig eyes.

The purpose of this study was to investigate the thermal injuries caused by ultrasonic pars plana phacoemulsification and aspiration (PPPEA) using pig eyes. Using a 20-gauge (G) vitrectomy system (Accurus®, Fragmatome; Alcon Laboratories) in both the 'open-tip' and 'closed-tip' techniques, PPPEA was performed in pig eyes and the subsequent thermal injuries generated around the scleral wound were measured by infrared thermal imaging (thermography). Post surgery, the state of the scleral wound was observed under a microscope, and a tissue slice containing the scleral wound was then prepared and observed under an optical microscope. Thermography measurements revealed a slight temperature rise around the scleral wound in the open-tip case, yet a marked temperature rise in the closed-tip case. The scleral wound incision produced by the open tip was linear, while that produced by the closed tip was expanded. Histological examination revealed mild degeneration of the sclera around the wound in the open-tip case, yet marked tissue degeneration by thermal injuries in the closed-tip case. Our findings showed that in PPPEA, the temperature of the tip of a 20G vitrectomy system rapidly increases due to the closed-tip technique, thus producing obvious thermal damage to the scleral wound. In order to prevent thermal injuries to the scleral wound during PPPEA, it is important to shorten the time of ultrasonic oscillation during surgery as much as possible while the tip is occluded with nuclear fragments.

Sutureless biplanar closure of leaking wounds in micro-incision vitreous surgery: A novel technique.

To describe a novel technique for sutureless hermetic closure of leaking scleral wounds in micro-incision vitreous surgery. This study is a two-centre, non-comparative, interventional case series. We studied 1240 scleral incisions on 870 eyes using different gauges (20, 23, 25) to evaluate the effectiveness of a new technique to seal scleral wounds without sutures. If wounds were found leaking after removing the trocar, we used the same trocar (or microvitreoretinal) blade to make an adjacent trans-scleral entry in the same direction as the main incision to access its internal flap supporting it from inside. Simultaneously, we applied a blunt smooth-surface instrument to massage the scleral wound from outside to close it hermetically. We treated 870 eyes using three types of tamponading agents, namely, silicone oil in 654 (75%) eyes, non-expansible gas in 128 (15%) eyes, and air in 88 (10%) eyes. We performed optical coherence tomography in the first 100 sclerotomies on the post-operative Day 1. We closed leaking incisions at the first attempt in 1231 (99.3%) cases; in 9 (0.7%) cases of 20-gauge incisions, we closed the wounds at the second attempt. We observed no hypotony at the end of surgery. The mean intraocular pressure was 16 mmHg (8-51 mmHg) on the post-operative Day 1. Our results show the biplanar closure technique may be used as an effective, quick, sutureless approach to close leaking wounds hermetically in micro-incision vitreous surgery procedures. It is safe, less traumatic, cost-effective, and easy-to-perform typical surgical settings.

Simple Technique For The Management Of A Cataract Surgery Wound Site Scleral Abscess and Endophthalmitis

To report satisfactory outcome in a patient with scleral abscess at scleral incision cataract surgery wound site, along with endophthalmitis. Simple adjunctive measures enhance the success of conservative management for such cases. Method: Seventy-year-old female was diagnosed as scleral abscess with acute post operative endophthalmitis after one week of an uneventful scleral incision cataract surgery. The patient was managed with surgical wound debridement adjunctive to topical, intravitreal and systemic antibiotics. Results: Satisfactory final best corrected visual acuity of 20/40 was achieved at the last follow-up at 20 weeks. Conclusion: Post cataract surgery scleral abscess and endophthalmitis pose a significant management challenge. This condition may respond favourably with adjunctive meticulous surgical wound debridement.

Cauterization of Ozurdex wound for the prevention of scleral leakage in vitrectomized eyes.

To study if cauterization of the scleroconjuctival wound secondary to intravitreal dexamethasone implant in vitrectomized eyes is effective to avoid scleral leakage and hypotony. A total of 35 vitrectomized eyes of 35 consecutive patients with macular edema who underwent a single intravitreal dexamethasone implant injection in the operating room at the Eye Clinic of the University of Bari, Italy, from 2013 to 2017 were retrospectively reviewed. At the end of the injection, transconjuctival/scleral bipolar cauterization was applied at the injection site and the presence or absence of leakage or hypotony was studied. At the end of the procedure, no patient showed fluid leakage from the cauterized scleroconjuctival wound. No ocular hypotony of other ophthalmic complications were observed at 1 hour and 1 day from injection and intraocular pressure did not change significantly from baseline at 1 hour and 1 day after injection. Cauterization of the scleral wound after intravitreal dexamethasone implant injection in vitrectomized eyes is safe and effective to avoid scleral leakage with secondary hypotony, obtaining a watertight wound closure.

27-gauge and 25-gauge vitrectomy day surgery for idiopathic epiretinal membrane

BackgroundThis study compared the postoperative outcomes of 27-gauge (G) and 25-G vitrectomy performed for the treatment of idiopathic epiretinal membrane (ERM).MethodsThe study design was single center, retrospective, interventional case series. Two hundred consecutive eyes that underwent primary vitrectomy for ERM (27-G vitrectomy in 100 eyes and 25-G vitrectomy in 100 eyes) were studied for 6 months. In all eyes, scleral tunnels were made using angle incisions, and air or gas exchange was performed.ResultsThere were no significant differences in age, spherical diopter power, as well as preoperative Early Treatment Diabetic Retinopathy Study (ETDRS) score, central retinal thickness (CRT), and intraocular pressure between the 27-G and 25-G groups. The proportions of simultaneous cataract surgery (27-G vs. 25-G: 82% vs. 90%), air-filled eyes (99% vs. 98%), and scleral wound suture at the end of surgery (0% vs. 0%) were not significantly different between two groups. The mean operation time for vitrectomy was significantly (P = 0.0322) longer by 4 min for 27-G (37 min) compared to 25-G (33 min) vitrectomy. Gain in ETDRS score was significantly (P = 0.0421) better in 27-G group (4.7 ± 8.1 letters) compared to 25-G group (1.1 ± 13.6 letters) at 1 month post-vitrectomy, but not significantly different at 3 and 6 months (P = 0.0835 and 0.0569, respectively). Decrease in CRT was significantly (P = 0.0354) greater in 27-G group (−24.2 ± 50.0 μm) compared to 25-G group (−8.0 ± 48.6 μm) at 1 month post-vitrectomy, but not significantly different at 3 and 6 months (P = 0.6059 and 0.1725, respectively). On postoperative day 1, hypotony (≤ 6 mmHg) was observed in 2 eyes in 27-G group and 6 eyes in 25-G group, while ocular hypertension (≥ 25 mmHg) was found in 4 eyes in 27-G group and 11 eyes in 25-G group, with no significant differences between two groups. Postoperative complications requiring treatment occurred in one eye (vitreous hemorrhage) in 27-G group, and in two eyes (vitreous hemorrhage and retinal detachment in one eye each) in 25-G group.ConclusionsAlthough 27-G vitrectomy requires operation time of 4 min longer compared to 25-G vitrectomy for ERM surgery, using the 27-G system results in earlier recovery of visual acuity, CRT improvement and stabilized ocular pressure.

Scleral wound healing with cross-link technique using riboflavin and ultraviolet A on rabbit eyes.

PurposeThe aim of study was to evaluate the cross-link using riboflavin and ultraviolet A (UVA) for improving scleral wound healing.Materials and methodsThis was an experimental study involving four New Zealand rabbits (eight eyes). Therapy procedure was chosen for the right eye and control procedure for the left one. UVA irradiation of 365 nm with a surface irradiance of 3 mW/cm2 and a photosensitizer of riboflavin drops were applied for 30 minutes on the right eye at 2 mm from the limbus. Sclerotomy incision was performed at 2 mm from the limbus in both right (on the cross-link-treated area) and left eye. Then, 30 days after surgery, a morphological analysis and histological staining with hematoxylin–eosin and picrosirius red were performed, and the sclerotomy cicatrization of right and left eyes was compared. The variables investigated were as follows: sclerotomy incision pictures and measurements were made using the ImageJ Software. Scleral thickness was measured (employing the anterior optical coherence tomography and the digital caliper). Collagen fiber density stained with picrosirius red staining was measured using the Image Pro Plus software.ResultsThe morphological analysis showed that in all samples, the right eye presented sclerotomy closure, and in two eyes, among them, there were no visible edges of the sclerotomies incision. The left eye presented sclerotomy closure and incision edges. The Image Pro demonstrated a higher density of collagen fibers in the right eye when compared to the one. The statistical analysis was significant when compared to the collagen fiber density in the treated eyes with the control eyes.ConclusionThe cross-link procedure resulted in a better sclerotomy wound healing.

Clinical outcomes in traumatic pseudophacocele: A rare clinical entity.

Purpose:The purpose of this study is to evaluate the clinical outcomes in patients with traumatic pseudophacocele.Methods:In this retrospective, interventional case series, scleral wound repair with pars plana vitrectomy and glued intrascleral fixation of an intraocular lens (glued IOL) was performed in 5 eyes of 5 patients. Pupilloplasty was performed in 3 cases whereas aniridia glued IOL fixation was done in 1 case that had total avulsion and loss of iris tissue. The main outcome measures were best-corrected visual acuity (BCVA), intraoperative and postoperative complications during the entire follow-up period.Results:The preoperative vision ranged from hand movement to perception of light in all the patients. The mean postoperative BCVA was 0.42 ± 0.21 Snellen's decimal equivalent (SDE) at final follow-up. Postoperatively, all the cases retained good visual acuity with case 1 and case 2 reporting 0.5 SDE, case 3 had 0.33 SDE, case 5 had 0.67 SDE whereas case 4 had a final visual acuity limited to 0.1 SDE due to associated corneal opacity. The mean follow-up period was 20.2 ± 11.7 months (range from 9 months to 36 months). The IOL was well centered, all the wounds were well apposed and the mean postoperative intraocular pressure was 14.6 ± 1.95 mm Hg. No complications were reported in the entire follow-up period.Conclusion:The clinical outcomes of management of pseudophacocele were encouraging with retention of reasonably good visual potential in all cases.

Clinical observation of biological amnion transplantation in treating the huge pterygium

Objective To observe curative effects of biological amnion transplantation to treat the huge pterygium. Methods 86 eyes were divided into two groups randomly(by random number table). Group A were eyes treated with cutting the pterygium and uncovered sclarel wound.Group B were eyes treated with biological amnion which had been transplanted on scleral wound and all conea after the pterygium had cut.The irritative symptoms, heal time of corneal wound, relapse rate after half year were recorded. Results Its mild irritative symptoms such as foreign body sensation, photophobia and pain in group B were lighter than those in group A(χ2=6.08, P=0.01, χ2=31.40, P=0.00, χ2=14.18, P=0.00). The time of corneal wound heal was 5.21±0.89 days in group A and it was (4.02±0.71)days in group B. The statistic was significant(t=6.85, P=0.00). There was no significant difference in relapse rate after half year between group A and group B(χ2=1.40, P=0.24). Conclusion Biological amnion transplantation can alleviating irritative symptoms and shortening heal time in huge pterygium operation. Key words: Pterygium; Biological amnion; Transplantation

Poly-N-isopropylacrylamide (pNIPAM): a reversible bioadhesive for sclerotomy closure.

PurposeTo determine the safety and efficacy of poly-N-isopropylacrylamide, a thermoresponsive adhesive, for sutureless sclerotomy closure in rabbits.MethodsEight rabbits were randomized into three groups: short-term acute, mid-term chronic, and long-term chronic studies. A corresponding control group in which the scleral wounds were sutured by 6–0 vicryl sutures was assigned for each study group. A 20-gauge sclerotomy was performed following a core vitrectomy and 0.1 mL of 50 % liquid poly-N-isopropylacrylamide was applied to the scleral wounds. Before the polymer application, the scleral surface was raised above 32 °C using a halogen bulb lamp. Follow-up exams included color external and fundus photography, fundus fluorescein angiography, optical coherence tomography, and electroretinography. After the last follow-up assessment, the rabbits were sacrificed and histopathological studies on the scleral incision sites were performed.ResultsScleral wound healing was observed in the long-term chronic study rabbits. Histological studies were able to identify poly-N-isopropylacrylamide polymer at the sclerotomy site in the mid-term chronic study rabbits. Besides iatrogenic cataracts due to mechanical instrument touch in 2 rabbits, no other ocular abnormalities were identified in any of the eyes in the perioperative setting or during the follow-up period. Cornea, retina, and vitreous remained unaffected, and no abnormal inflammatory reaction or endophthalmitis was noticed in the 3 study groups. Filtering blebs indicative of leakage through the sclerotomies were not observed during the follow-up period.ConclusionPoly-N-isopropylacrylamide may provide effective in vitro scleral adhesion above 32 °C. Clinical studies are required to evaluate its utility in patients undergoing pars plana vitrectomy.

Clinical characteristics and prognostic factors of scleral rupture due to blunt ocular trauma.

PurposeTo describe and identify ocular and wound characteristics, and prognostic factors associated with final visual acuity (VA) in patients with scleral rupture due to blunt ocular trauma.MethodsThe medical records of 61 patients with globe rupture due to blunt ocular trauma who underwent primary repair were reviewed retrospectively. The data recorded included demographic characteristics, initial and final VA, ocular signs, wound characteristics, and surgeries. Initial VA, ocular signs, wound characteristics, and surgeries were analyzed to determine the association with the final VA.ResultsForty three women and 18 men with a mean age of 43.6±23.5 years were included in the study. The locations of scleral wounds were mostly in the superonasal quadrant (41.0%) and zone 2 (75.4%). In eyes with hyphema (P=0.009), vitreous hemorrhage (P=0.001), and retinal detachment (P=0.004), final VA was statistically worse than eyes without these signs. A moderate positive correlation was found between the initial and final VA (P<0.001). Final VA was statistically worse in eyes with horizontal midline wounds than in eyes with vertical midline wounds (P=0.002). A moderate negative correlation was found between scleral wound length and final VA (P<0.001). Patients who underwent cataract surgery had statistically better final VA (P=0.002).ConclusionsScleral rupture was detected mostly in females, superonasal quadrant and zone 2. Poor final VA was significantly associated with poor initial VA, longer wound length, horizontal midline wound, presence of hyphema, vitreous hemorrhage and retinal detachment at presentation, and cataract surgery not performed during follow-up period. Scleral ruptures have different demographic, ocular and wound characteristics than other open globe injuries.

27-GAUGE NEEDLE-ASSISTED TECHNIQUE FOR REPOSITIONING A DISLOCATED INTRAOCULAR LENS.

Several techniques for the reposition of a posterior chamber intraocular lens (IOL) posterior dislocating into the vitreous cavity have been developed. However, most of these methods are complicated or include externalizing part of the IOL from a corneal or scleral wound. We here describe a 27-gauge needle-assisted technique for management of a dislocated posterior chamber IOL. This is a retrospective, noncomparative, interventional case series that discusses the results of 27-gauge needle-assisted reposition of the posterior chamber IOL with transscleral sulcus fixation in 5 consecutive cases with an IOL dislocated into vitreous cavity. These patients underwent IOL reposition with the above-mentioned technique between April 2013 and October 2014 and were followed up for at least two months thereafter. The IOLs of the five cases were stable with proper centrations. The postoperative best-corrected visual acuity ranged from 20/30 to 20/20. The technique of 27-gauge needle-assisted reposition of the posterior chamber IOL with transscleral fixation is effective for reposition of a dislocated IOL. This technique provides good IOL fixation without creating a large corneal wound or scleral flap.

Argus II retinal prosthesis implantation with scleral flap and autogenous temporalis fascia as alternative patch graft material: a 4-year follow-up.

IntroductionThe Argus II retinal prosthesis is composed of an epiretinal electrode array positioned over the macula and connected to an extrascleral electronics case via a silicone cable, running through a sclerotomy. During implantation, the manufacturer recommends to cover the sclerotomy site with a patch of processed human pericardium to prevent postoperative hypotony and conjunctival erosion by the underlying electronics case. Due to biomedical regulations prohibiting the use of this material in France, we developed an alternative technique combining a scleral flap protecting the sclerotomy and an autogenous graft of superior temporalis fascia overlying the electronics case.MethodsThe purpose of this study is to describe the 4-year outcomes of this modified procedure in three subjects who underwent Argus II Retinal Prosthesis System implantation. Clinical data consisting of intraocular pressure measurements and tolerance in terms of conjunctival erosion or inflammation were retrospectively assessed over a 4-year postoperative follow-up.ResultsNone of the three patients implanted with the modified technique developed ocular hypotony over 4 years. A normal, transient conjunctival inflammation occurred during the first postoperative month but conjunctival erosion was not observed in any of the three patients over 4 years. Four years after implantation, the autogenous temporalis fascia graft remained well tolerated and the retinal prosthesis was functional in all three patients.ConclusionThe combination of an autograft of superficial temporalis fascia and a scleral flap efficiently prevented leakage through the sclerotomy site, ocular hypotony, and conjunctival erosion by the extrascleral electronics case. This modified technique is suitable for the implantation of existing and forthcoming retinal prostheses. Superficial temporalis fascia may also be used as alternative to commercial tectonic tissues for scleral wound repair in clinical settings where they are not available.

Polyethylene Glycol-Based Synthetic Hydrogel Sealant for Closing Vitrectomy Wounds: An In Vivo and Histological Study.

PurposeWe conducted an in vivo study using Dutch pigmented rabbit eyes to test the usefulness of polyethylene glycol (PEG) sealant for the closure of sutureless sclerotomies in microincisional vitrectomy surgery (MIVS).MethodsThree-port, 23-gauge vitrectomy was performed on rabbit eyes. After air leakage was confirmed by the application of 0.625% povidone–iodine at the sclerotomy site, PEG sealant was subconjunctivally injected using a 27-gauge needle through conjunctival incisions to cover the sclerotomy wounds, following which it was polymerized by the application of xenon light for 60 seconds. Ophthalmological examinations and intraocular pressure measurements were conducted the day before and 1, 3, 5, and 7 days after surgery. The eyes were enucleated for histological evaluation 7 days after surgery.ResultsPEG sealant was rapidly polymerized by the application of xenon light after subconjunctival injection, and it firmly sealed the sclerotomies without air leakage, as confirmed by povidone–iodine dropping, in all cases. Conjunctival and scleral wounds closed with PEG sealant were successfully attached and remained intact till the end of the follow-up period. There was no sign of postoperative hypotony or infection in any eye, and no adverse effects of PEG sealant were found. In histological examination, linear scar formation and eosinophilic staining of collagen fibers were observed at the sclerotomy sites, while the sclerotomy tunnels appeared tightly closed.ConclusionsPEG sealant can be useful for the closure of sutureless 23-gauge vitrectomy incisions in rabbits.Translational RelevanceThe PEG sealant may become an effective option for closing vitrectomy incisions including pediatric cases.

Intravitreal phacoemulsification using torsional handpiece for retained lens fragments

Purpose:To evaluate the results of intravitreal phacoemulsification with torsional hand piece in eyes with posteriorly dislocated lens fragments.Methods:In this prospective, interventional case series, 15 eyes with retained lens fragments following phacoemulsification were included. All patients underwent standard three-port pars plana vitrectomy and intravitreal phacoemulsification using sleeveless, torsional hand piece (OZiL™, Alcon's Infiniti Vision System). Patients were followed up for a minimum of six months to evaluate the visual outcomes and complications.Results:The preoperative best-corrected visual acuity (BCVA) ranged from light perception to 0.3. No complications such as thermal burns of the scleral wound, retinal damage due to flying lens fragments, or difficult lens aspiration occurred during intravitreal phacoemulsification. Mean post-operative BCVA at the final follow-up was 0.5. Two eyes developed cystoid macular edema, which was managed medically. No retinal detachment was noted.Conclusion:Intravitreal phacoemulsification using torsional hand piece is a safe and effective alternative to conventional longitudinal phacofragmentation.

Clinical features and prognosis of eyeball rupture: eye injury vitrectomy study.

The objective of the study was to delineate clinical characteristics, surgical interventions, anatomic and visual outcomes of ruptured eye balls after trauma, and establish the prognostic indicators, which can assist clinicians in making correct surgical decisions during globe exploration for ruptured eyes. The study design used was a multicentre prospective cohort study, including six university-affiliated tertiary hospitals. We selected 242 cases of ruptured globe from the Eye Injury Vitrectomy Study database, until 31 December 2012. All selected cases underwent vitreoretinal surgery, enucleation or evisceration, and were followed up for at least 6 months. Age, visual acuity (VA) after injury, ocular trauma zone, time to surgery, corneal laceration, scleral wound, extrusion of iris or lens, ciliary body damage, intraocular haemorrhage, retinal detachment or defect, proliferative vitreoretinopathy (PVR) and choroidal damage were the predisposing factors evaluated by logistic regression models. We compared the pre-surgical indicators between cases of anatomically restored eyes with VA of 4/200 or better, or eyes with initial no light perception restored light perception or better, and cases of VA worse than 4/200, silicone oil-sustained eyes, phthisis or enucleation. Nearly 40% of cases with ruptured globe were anatomically restored through vitreoretinal surgery. The closed-funnel retinal detachment or extensive retinal loss (odds ratio [OR] = 3.38, P = 0.026), PVR-C (OR = 3.45, P = 0.008), and choroidal damage (OR = 4.20, P = 0.004) were correlated with poor outcomes. The closed-funnel retinal detachment or extensive retinal loss, PVR-C, and choroidal damage are the risk factors for unfavourable outcomes in globe ruptures.

Clinical presentations and outcomes following ocular injury with intraocular foreign bodies

Context: Globally, of 55 million ocular trauma cases occurring per year, 1.6 million are rendered blind. Intraocular foreign bodies (IOFBs) form a major subset (40%) of the penetrating eye injuries. Aims: To study the clinical presentations, visual outcomes, and the prognostic factors in penetrating eye injuries with IOFB. Settings and Design: This is a prospective cohort study conducted at a tertiary care center. Thirty-three eyes of 33 consecutive patients presenting to our center between March and December 2012 with IOFB injury were included in the study. Materials and Methods: After obtaining informed consent, detailed history and examination findings were noted at presentation. Computed tomography scanning was done in all patients. The details of the IOFB extraction procedure were noted and the patients were followed up for 3 months following the surgery. Statistical Analysis Used: All statistical calculations were performed in Stata (12.1) using the t-test. Results: Fifty-three percent were males between 15 and 30 years of age. Seventy-three percent had foreign body located in the posterior segment, whereas 27% were located in the anterior segment. The incidence of endophthalmitis was 16.67%. The final best corrected visual acuity appeared to be worse with poorer vision at presentation, larger foreign body size, scleral entry wound, and foreign body removal during a secondary surgery. Conclusions: Penetrating eye injuries with IOFB usually occurred in young males at work places. Factors leading to poor visual outcome were poor vision at presentation and larger foreign body size.

Autologous advanced tenon grafting combined with conjunctival flap in scleromalacia after pterygium excision.

Purpose. To evaluate the efficacy of autologous tenon grafting combined with conjunctival flap as a treatment for scleromalacia or scleral thinning after pterygium excision without any additional donor graft tissue. Methods. Twenty-six cases underwent autologous advanced tenon grafting combined with sliding or rotating conjunctival flap for scleromalacia after pterygium surgery ranging from 2 years to 30 years. The extent of scleral defect measured from 2.0 mm to 6.8 mm in diameter. The cosmetic outcome was defined as complete resolution of scleromalacia or completely conjunctival reepithelialization and firm adhesion between subtenon and scleral tissue over scleral thinning without significant complications. Results. All cases achieved the covering of conjunctival and tenon or subtenon tissue over scleromalacia or scleral thinning with this procedure. Preoperative pain, inflammation, and choroidal exposure disappeared after surgery. Immediate postoperative complications, such as large wound dehiscence or reopening of the scleral wound, did not occur in any of the patients. There were no significant clinical complications during the mean postoperative follow-up period of 14.17 months in all cases. Conclusions. We obtained excellent outcome with fewer complications after autologous advanced tenon graft and conjunctival flap, without an additional donor graft, in scleromalacia or scleral thinning caused by previous pterygium excision.
