Purpose: : To report the rate of progression of crystalline lens nuclear sclerotic opacification following vitrectomy and gas tamponade for macular hole repair Methods: : 98 patients undergoing elective surgery for a macular hole in one eye (46 left, 52 right) were recruited for this prospective study. Baseline (pre-operative) Scheimpflug densitometry analysis was performed. All patients had vitrectomy, internal limiting membrane peel and gas tamponade. Post-operative Scheimpflug measurements were carried out at three-monthly intervals until cataract surgery or up to one year Results: : There was no significant difference in mean Scheimpflug lens densitometry readings between the eyes with a macular hole and their fellow eyes at baseline. At three months, however, the operated eyes showed a relative increase in lens densitometry of 10.5% compared to the fellow eye (n=90). This increased to 21.5% at 6 months (n=77) and 28.9% at 9 months (n=39). At 1 year, lens densitometry readings were 19.7% ...
Purpose: Removal of the internal limiting membrane (ILM) during pars plana vitrectomy (PPV) has been shown to improve macular hole closure, reduce rates of post operative epiretinal membrane (ERM) formation in rhegmatogenous retinal detachments, and reduce macular thickness in patients with refractory diabetic macular edema. We conducted a retrospective study evaluating clinical outcomes in patients who underwent ILM peeling during pars plana vitrectomy for the treatment of proliferative diabetic retinopathy.. Methods: We analyzed the outcomes of 71 patients (71 eyes) who underwent PPV and epiretinal membrane peeling, with or without ILM removal, for proliferative diabetic retinopathy complicated by tractional retinal detachment and/or vitreous hemorrhage. All patients had 12 months of post-operative follow up. The primary outcome measure at 12 months was ERM recurrence. The secondary outcomes were the presence of clinically significant macular edema (CSME) and visual acuity. Preoperative and ...
Degenerative myopia is relatively common disorder, especially in Korean, Japanese and Chinese.. Choroidal neovascularization is well-noted cause of VA deterioration, but nowadays, with improvement of diagnostic tools, such as OCT, VA deterioration from myopic tractional maculopathy is being concerned as well.. But till now, the necessity of early vitrectomy on MTM is controversial. By now some clinicians prefer conservative treatment, which means pars plana vitrectomy would be postponed till structural change such as macular hole formation is noticed. And the others prefer early vitrectomy, which means pars plana vitrectomy should be performed when the symptom begins.. In this study, investigators try to verify the validity of early vitrectomy comparing conservative treatment. ...

AIM--To describe the phenomenon of peripheral field loss following routine pars plana vitrectomy for stage 2 and 3 full thickness macular hole and to investigate the underlying mechanism. METHODS--Five patients, who reported peripheral field defects after apparently uncomplicated vitrectomy, posterior cortical vitreous peeling, and perfluoropropane (C3F8) gas tamponade, were studied retrospectively with slit-lamp biomicroscopy, automated and kinetic perimetry, fundal fluorescein angiography, focal electroretinography (ERG), and colour contrast sensitivity (CCS) testing. RESULTS--All five patients, who were between 50 and 73 years of age, reported an inferotemporal field defect following resolution of the intraocular gas bubble. In all eyes, the scotomata encroached to within 20 degrees to 30 degrees of fixation and to within 5 degrees to 15 degrees of the blind spot. In one eye, a partial altitudinal component was evident. All scotomata subsequently remained stable and three eyes developed ...

Objective. To describe the pathogenic mechanism for a central retinal detachment in eyes with a pit of the optic disc. Design. Three patients with macular detachment associated with optic nerve head pits were prospectively controlled following pars plana vitrectomy. Methods. Three cases of macular detachment associated with congenital optic nerve pit were treated with pars plana vitrectomy and air-fluid exchange and sulphur hexafloride (SF6) gas injection. During vitrectomy posterior hyaloid removal caused visible traction on the elevated retina, when the hyaloid detached. Removing the posterior hyaloid resulted in reattachment of the macular and an increase in the visual acuity without laser treatment. Conclusion. We recommend the removal of the posterior hyaloid face during pars plana vitrectomy in patients with central macular detachment associated with a pit of the optic disc.

This study showed no significant difference between the final outcomes in patients treated with a vitrectomy and gas or a vitrectomy with gas and scleral buckle (p = 0.6). The decision to use a buckle in combination with a vitrectomy is usually taken in the presence of inferior retinal breaks or PVR. As mentioned earlier, this procedure is technically more demanding, has an increased risk of choroidal haemorrhage,5 requires a longer operating time,6 and has all the associated complications of a scleral buckle-that is, exposure, refractive change, diplopia, possible decreased retinal blood flow, and risk of anterior segment ischaemia.7-12 The increased risks of this technique would be justified if it was associated with superior outcomes; however, the results of this study would suggest that this is not the case when treating inferior break retinal detachments. At present there is little published on the outcomes of vitrectomy and gas alone in these cases. Tanner et al published a prospective ...

Vitrectomy is one of the most important ocular surgeries. It can be used for patients with diabetic retinopathy, retinal detachment, ocular trauma, and endophthalmitis. Generally, vitrectomy is performed with microscopic assistance. However, in some situations such as corneal opacity and synechia of pupil, it cannot be done due to optic media opacity. Endoscope-assisted vitrectomy may be helpful for those patients who cannot be treated by traditional vitrectomy. It can also be used for patients with uncontrolled high intraocular pressure. It will improve life quality of those patients significantly. Endoscope-assisted vitrectomy is used in many countries including USA, Japan, Korea and some in the Europe. We pioneer in Taiwan in doing Endoscope-assisted vitrectomy ...
Vitrectomy may not only remove vitreous hemorrhage but also prevent or relieve traction on the retina from contraction of the fibrovascular membranes that characterize severe proliferative diabetic retinopathy. It is important to determine whether early intervention with vitrectomy has a better visual outcome or instead produces a rate of serious complications higher than the rate associated with conventional management.. Two randomized trials were carried out in the DRVS among patients ages 18 to 70 years who had either insulin-dependent or non-insulin-dependent diabetes. In the first trial, the 616 patients who were recruited had severe visual loss from recent severe vitreous hemorrhage in at least one eye. Eligible eyes were randomly assigned either to early vitrectomy or to conventional management. In the conventional management group, vitrectomy was carried out 1 year later if hemorrhage persisted; vitrectomy was carried out sooner if retinal detachment -involving the center of the macula ...
Purpose: To assess the relationship between day one post-operative intra-ocular pressure and patient demographic information, lens status, tamponade medium (air, perfluoroethane, sulfur hexafluoride) and laser treatment.. Methods: A prospective observational study of all patients undergoing pars plana vitrectomy by a single surgeon within one case study. All patients had intraocular pressure recorded one-day after surgery. None of the patients had postoperative anti-glaucoma medications. All patients undergoing pars plana vitrectomy were previously pseudophakic or underwent combined surgery.. Results: Out of a final cohort of 161 patients, 6% had raised IOP (defined as ,30mmHg). A parsimonious regression model showed no strong correlation between raised IOP and type of gas tamponade (p=0.028 for C2F6, p=0.067 for SF6, air was the reference category), and a moderate association with number of laser burns (p=0.067).. Conclusion: The use of gas tamponade, in particular C2F6, does not constitute ...
While sleeping was tough after the vitrectomy surgery, the days werent too bad. Somehow, the days flew by and merged into each other so I almost lost track of time. I cant exactly explain it, but perhaps it was because everything took so much longer that doing just a few things took up the whole day. Also, the regimen of 12 applications of eye drops or ointment to my eye took quite a bit of time and effort each day.. Eating was slow, and I had to eat things that werent fiddly and could easily be stuffed into my mouth as I faced straight down. Foods like taquitos and sausages worked well, for example. Drinking was also a pain, because I needed to use a straw for everything. Drinking coffee through a straw is unusual, but I learned to get used to it. I had a fair number of Boost drinks in the first few days, as they were very easy for breakfast, and some of them taste darn good!. During the days, I needed a cot to lay on as I tried to keep myself amused. Before the surgery, I bought a cot from ...

BACKGROUND: The inverted flap (IF) technique has recently been introduced in macular hole (MH) surgery. The IF technique has shown an increase of the success rate in the case of large MHs and in MHs associated with high myopia. This study reports the anatomical and functional results in a large series of patients affected by MH treated using pars plana vitrectomy and gas tamponade combined with internal limiting membrane (ILM) peeling or IF. METHODS: This is a retrospective, consecutive, nonrandomized comparative study of patients affected by idiopathic or myopic MH treated using small-gauge pars plana vitrectomy (25- or 23-gauge) between January 2011 and May 2016 ...
The use of modern office-based vitrectomy has greatly evolved since it was first introduced [3-5, 10-12, 14]. Newer models have allowed for better visualization and more precise surgical maneuvers to be performed within the clinic or minor procedure room. While not a replacement for in-OR 3-port pars-plana vitrectomy, the potential of the office-based vitrector now seems expansive [3, 4, 10-12, 14]. The incidence of reported complications and endophthalmitis following office-based vitrectomy remains largely unknown. The largest combined study to date of 4509 single-port procedures performed using the Intrector places endophthalmitis rates at around 0.17% (62.9% in an office setting, 37.1% in an OR setting) [5]. This data differs from our studys surgical model where all procedures were three-port and performed in the office setting. Comparatively, modern endophthalmitis rates for standard 23-ga and 25-ga MIVS are reported at around 0.02-0.10%, although values ranging from 0.02%-0.80% have been ...

Vitrectomy is a surgery to remove the vitreous humor from the eye. Pars plana vitrectomy eye surgery is used to remove eye floaters or vitreous blood.
When the vitreous gel becomes opacified or filled with blood, the retina may detach from scar tissue pulling on it. Standard retinal detachment procedures cannot be used in such cases and the ophthalmologist may recommend a vitrectomy. A vitrectomy is a microsurgical procedure that involves making one or more incisions into the side of the eye and, with special instruments, removing the blood-filled vitreous material and scar tissue. The vitreous may be replaced with a clear solution, air or gas to keep the retina in place at the back of the eye. Eventually, clear fluid from the blood flows into this space to fill it permanently. Occasionally, in complicated cases, silicone oil must be injected into the eye to reattach the retina. This oil is usually removed a few months after the operation. Vitrectomy may be used in conjunction with other retinal detachment procedures, but generally it is reserved for complex retinal detachments that cannot be repaired by more conventional means.. Vitrectomy is ...
To evaluate the benefits of lutein in preventing retinal phototoxicity generated by xenon light sources during vitreoretinal surgery. A prospective cross-sectional study in pigmented rabbit eyes exposed to different vitreoretinal surgery lighting simulations. Twenty Dutch-belted rabbits were divided into two groups exposed to two different xenon wavelength light sources filters (420 nm and 435 nm). In addition, two subgroups were administered with daily supplemental of 10 mg of Lutein systemically. Electroretinography (ERG), optical coherence tomography (OCT) and fluorescein angiography (FA) were performed before and after surgery to quantify the retinal damage. All animals submitted to the experiment presented some degree of phototoxicity independent of wavelength light filter used. Retinal damage was evident as the FA presented areas of hyperfluorescence, and the OCT depicted increased reflective areas of the inner and outer retinal layers, and RPE. ERG showed a diffuse reduction of the a and b waves

AU - McLeod, David. AU - Michels, Ron. AU - Scott, John. AU - Wilson, Donald. PY - 1987. Y1 - 1987. N2 - Thirty-six pars plana vitrectomies were performed on 30 eyes of 17 patients with biopsy-proven vitreous amyloidosis. Reopacification of the retrolental vitreous was the most common reason for vitrectomy revision, required in 24% of patients. Complications of amyloid or vitrectomy included retinal detachment requiring scleral buckling in 17% of eyes and glaucoma requiring filtering surgery in 17% of eyes. After a mean 35-month post-vitrectomy follow-up, 48% of eyes had visual acuities of 20/40 or better, and 32% of eyes had visual acuities between 20/50 and 20/100. Twenty percent of eyes had visual acuities of 20/200 or worse due either to persistent retinal detachment, open angle glaucoma, or residual ...
Purpose: We 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). Methods: Three-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. Results: PEG 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 ...
PURPOSE: To conduct zymographic analysis to study the matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) in vitreous samples of patients undergoing pars plana vitrectomy as part of the treatment of vitreoretinal disease. METHODS: Forty-two vitreous samples were collected at the time of pars plana vitrectomy. Diagnoses included severe (exudative) age-related macular degeneration (AMD) (12), macular hole (10), presumed ocular histoplasmosis syndrome (6), proliferative diabetic retinopathy (PDR) (5), epiretinal membrane (4), vitreomacular traction syndrome (2), macroaneurysm with subretinal hemorrhage (1), central retinal vein occlusion with vitreous hemorrhage (1), and proliferative vitreoretinopathy (1). Gelatin zymography, reverse gelatin-zymography, carboxymethylated transferrin zymography, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis were performed on the liquid vitreous samples to assess for MMP and TIMP activity. RESULTS: Progelatinase A occurred in
Conditions which can benefit from vitrectomy include: Vitreous floaters - deposits of various size, shape, consistency, refractive index, and motility within the eyes normally transparent vitreous humour which can obstruct vision. Here pars planar vitrectomy has been shown to relieve symptoms[3], however, because of possible side effects it is only used in severe cases. Retinal detachment - a blinding condition where the lining of the eye peels loose and floats freely within the interior of the eye. Steps to reattach the retina may include vitrectomy to clear the inner jelly, scleral buckling to create a support for the reattached retina, membranectomy to remove scar tissue, injection of dense liquids to smooth the retina into place, photocoagulation to bond the retina back against the wall of the eye, and injection of a gas or silicone oil to secure the retina in place as it heals. Macular pucker - formation of a patch of unhealthy tissue in the central retina (the macula) distorting vision. ...

PURPOSE To evaluate whether cataract surgery in children should be performed with anterior vitrectomy and to examine the properties of the AcrySof SA30AL intraocular lens (IOL) in the pediatric eye. SETTING Filatov Institute, Odessa, Ukraine. METHODS Cataract surgery was performed in 66 children aged 3 to 15 years. They were randomized to surgery with or without anterior vitrectomy. All eyes were implanted with the single-piece AcrySof SA30AL IOL (Alcon). During the study, the patients who needed surgery for after-cataract had a second surgical procedure. Two years after surgery, the surgical method was evaluated using exact logistic regression. Also, the Evaluation of Posterior Capsule Opacification (EPCO) score was compared between the patients who had surgery for after-cataract and the patients who did not need this. The presence of posterior synechias and centration of the IOL were assessed. RESULTS Children in the younger age group (|/=62 months at surgery) had surgery for after-cataract more

A consecutive series of 16 eyes in 16 patients with DME who underwent pars plana vitrectomy were recruited into the study. 2 of them suffered from diabetes mellitus type 1 (mean age was 37 years, diabetes duration was 20.5 years), 14 suffered from diabetes mellitus type 2 (mean age was 65±5.6 years, diabetes duration 15.9±6.5 years). All patients underwent 23Ga pars plana vitrectomy by one surgeon. The indication for the vitrectomy were DME with tractions or diffuse DME resisted to the therapy by VEGF inhibitors. There was one technique of the vitrectomy with membrane staining by Membrane Blue Dual, inner limiting membrane peeling and air tamponade in all cases. Spectral-domain optical coherence tomography and visual acuity were obtained preoperatively, 3 and 6 months after surgery. The observation period was 2 years or up to macular edema relapse. 6 patients had proliferative diabetic retinopathy (DR), 7 patients had nonproliferative DR, 9 patients were treated by laser photocoagulation ...
Cataract formation is the most frequent complication of pars plana vitrectomy, even without the use of air, gas, or silicone oil. The formation of lens opacities may occur intraoperatively, precluding adequate visualization during the last phases of a long procedure, or early postoperatively, making it difficult or impossible to complete fundus examination. Alternatively, a slow but progressive lens opacification following vitrectomy can be a ...
Lens removal during MH repair offers several advantages. First, lensectomy eliminates the need for an otherwise inevitable second surgical intervention for a post-vitrectomy cataract extraction (CE) especially given that in the Vitrectomy for Macular Hole Study, the incidence of nuclear sclerosis progression following vitrectomy was 100 percent at 2 years follow-up.(40) Second, early lensectomy avoids the direct surgical challenges associated with delayed CE in vitrectomized eyes.(41-43) Third, avoiding delayed CE following MH repair may help decrease the rate of hole reopening, since delayed CE itself has been implicated as a possible factor in late MH reopening in several studies.(40,44-46) These studies suggest that delayed CE may play a role in late MH reopening; however, the rate of MH reopening of 8.5 percent observed in our study was similar to that noted in the major report by the American Academy of Ophthalmology, which varied between 2 to 10 percent.(47) Fourth, lensectomy virtually ...

article{833773, abstract = {Background/aim: Little is known about biochemical markers related to change in visual acuity after vitrectomy. The potential use of transthyretin (TTR), a carrier of the retinol/retinol-binding protein, as a biochemical marker protein, was investigated. Methods: TTR was measured using immunonephelometry in a group of patients (n = 77) in longstanding ({\textrangle} 1 week) retinal detachment (n = 29), fresh ({\textlangle} 1 week) retinal detachment (n = 17), macular holes (n = 20) or diabetic retinopathy (n = 11). Vitreous samples were taken at the start of every vitrectomy procedure. For reference values, cadaver specimens (n = 73) were used. Results: Reference values for vitreous TTR (median 18 mg/l; IQR 4 to 24 mg/l) comprised 2.2\% of reference values for vitreous protein levels (median 538 mg/l; IQR 269 to 987 mg/l). Vitreous TTR values of patients were comparable in all disorders. Vitreous TTR values were higher in phakic (median 22.5 mg/l; IQR 10 to 27 mg/l) ...

A 60 years old female came to the Ophthalmology department with complaints of decreased visual acuity in both eyes. Ophthalmologic examination revealed a best corrected visual acuity (BCVA) of 1/10 in the right eye (RE) and 2/10 in the left eye (LE). Biomicroscopy revealed an incipient cortical cataract and fundoscopy a bilateral macular hole. Optical coherence tomography confirmed a bilateral stage 4 macular hole. Surgical management was performed in both eyes in different surgical times with cataract extraction and pars plana vitrectomy with internal limiting membrane (ILM) peeling. Visual acuity remained the same with no anatomical closure. Due to the low vision, a decision was made to reoperate the patient. A new pars plana vitrectomy was performed, with a mechanical push of the borders of the hole with forceps in order to decrease its size, and the placement of an inverted ILM flap over the macular hole. Vision improved to 3/10 in both eyes, with anatomical closure of the macular hole being ...
Surgery is performed as an outpatient procedure under either a local or general anaesthetic. During a vitrectomy, the surgeon inserts small instruments into the eye, cuts the vitreous gel, and suctions it out. The fluid that has accumulated underneath the retina can be drained away and the surgeon may treat the retina with a laser (photocoagulation) or cryotherapy, cut or remove fibrous or scar tissue from the retina, flatten areas where the retina has become detached, or repair tears or holes in the retina or macula.. To replace the vitreous a gas bubble may be injected into the eye. This gas holds the retina in place whilst healing occurs. The gas dissolves after varying periods. Whilst the gas is in the eye it usually blocks vision quite substantially. In addition a person with gas in their eye may not travel to high altitude, nor may they fly. Vitrectomy with gas injection may also cause a cataract to form. Frequently the pressure of the eye may need to be controlled.. The operation will ...

Surgery is not necessary for everyone who has a macular pucker. Eye drops, medicines, and lasers have no effect on this condition. For people who have only mildly blurred vision and are not bothered by it, no treatment is necessary. However, for those whose vision is more significantly affected, vitrectomy surgery is the only treatment that can remove a macular pucker. During this outpatient procedure, your doctor uses tiny instruments to remove the scar-tissue that is wrinkling the macula.. Usually, the macula flattens out. The symptoms slowly improve, although the vision does not always return to normal. Typically, patients can expect two or more lines of improvement on the eye chart, however cataracts (clouding of the natural lens in the eye) may develop or progress more rapidly after surgery to fix the macular pucker. Cataract surgery may be necessary to obtain the best vision after macular pucker surgery.. ...

The macula is the part of the retina responsible for acute central vision, the vision one uses for reading, watching television, and recognizing faces. A macular hole is a small round opening in the macula. The hole causes a blind spot or blurred area directly in the center of your vision.. Most macular holes occur in the elderly. When the vitreous (the gel-like substance inside the eye) ages and shrinks, it can pull on the thin tissue of the macula, causing a tear that can eventually form a small hole. Sometimes injury or long-term swelling can cause a macular hole. No specific medical problem is known to cause macular holes.. Vitrectomy surgery, the only treatment for a macular hole, removes the vitreous gel and scar tissue pulling on the macula and keeping the hole open. The eye is then filled with a special air bubble to push against the macula and close the hole. The air bubble will gradually dissolve, but the patient must maintain a face down position for one to two weeks to keep the gas ...

The fitting of Antoine equation (Equation 1) to experimental data of perfluor-n-octane,22 allows to obtain A = 18.92, B = 5892, and C = 36.7. Experimental data points and the fitting curve are plotted in Figure 1 that shows that the vapor pressure increases with temperature (i.e., decreases with increasing cohesion forces between the particles of the liquid). With increased temperature, the increasing number of particles on the surface of the liquid has a sufficient kinetic energy to overcome the cohesion forces to pass vapor state. The partial pressure (or the fugacity) of perfluor-n-octane in the gas phase, PPC, is an index showing how much the liquid-vapor system is away from equilibrium. Indeed, if we assume that the vapor phase is ideal, the partial pressure takes the form where CPC (Equation 2) is the molar density of perfluor-n-octane in vapor phase. Generally, the vitrectomy surgery experiences a limited range of temperatures (T1, T2). Therefore, as a first approximation, one can assume ...
