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 ...

PURPOSE: To evaluate preretinal partial pressure of oxygen (PO2) gradients before and after experimental pars plana vitrectomy. METHODS: Arteriolar, venous, and intervascular preretinal PO2 gradients were recorded in 7 minipigs during slow withdrawal of oxygen-sensitive microelectrodes (10-μm tip diameter) from the vitreoretinal interface to 2 mm into the vitreous cavity. Recordings were repeated after pars plana vitrectomy and balanced salt solution (BSS) intraocular perfusion. RESULTS: Arteriolar, venous, and intervascular preretinal PO2 at the vitreoretinal interface were 62.3 ± 13.8, 22.5 ± 3.3, and 17.0 ± 7.5 mmHg, respectively, before vitrectomy; 97.7 ± 19.9, 40.0 ± 21.9, and 56.3 ± 28.4 mmHg, respectively, immediately after vitrectomy; and 59.0 ± 27.4, 25.2 ± 3.0, and 21.5 ± 4.5 mmHg, respectively, 2½ hours after interruption of BSS perfusion. PO2 2 mm from the vitreoretinal interface was 28.4 ± 3.6 mmHg before vitrectomy; 151.8 ± 4.5 mmHg immediately after vitrectomy; and 34.8

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

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

This study compared the postoperative outcomes of 27-gauge (G) and 25-G vitrectomy performed for the treatment of idiopathic epiretinal membrane (ERM). The 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. There 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

Use of 25% sulfur hexafluoride gas mixture may minimize short-term postoperative hypotony in sutureless 25-gauge pars plana vitrectomy surgery Yoreh Barak, James W Heroman, Shlomit SchaalDepartment of Ophthalmology and Visual Sciences, University of Louisville, Louisville, KY, USABackground: The purpose of this study was to compare postoperative intraocular pressures and percentage of vitreous cavity gas fill one day following 25-gauge pars plana vitrectomy with 20% versus 25% sulfur hexafluoride (SF6) gas fill.Methods: This was a retrospective review of 187 consecutive cases of 25-gauge pars plana vitrectomy with complete fluid/gas exchange. The main outcome measures included percentage of gas fill of the vitreous cavity and intraocular pressure on postoperative day one.Results: Fifty eyes underwent 25-gauge pars plana vitrectomy with 20% SF6 tamponade and 137 with 25% SF6 tamponade. On postoperative day one in the 20% SF6 group, there were five (10%) patients with hypotony (intraocular pressure ≤ 5

Purpose The direct cost to the National Health Service (NHS) in England of pars plana vitrectomy (PPV) is unknown since a bottom-up costing exercise has not been undertaken. Healthcare resource group (HRG) costing relies on a top-down approach. We aimed to quantify the direct cost of intermediate complexity PPV. Methods Five NHS vitreoretinal units prospectively recorded all consumables, equipment and staff salaries during PPV undertaken for vitreomacular traction, epiretinal membrane and macular hole. Out-of-surgery costs between admission and discharge were estimated using a representative accounting method. Results The average patient time in theatre for 57 PPVs was 72 min. The average in-surgery cost for staff was £297, consumables £619, and equipment £82 (total £997). The average out-of-surgery costs were £260, including nursing and medical staff, other consumables, eye drops and hospitalisation. The total cost was therefore £1634, including 30 % overheads. This cost estimate was an ...

To describe the results of refractive lens exchange (RLE) combined with simultaneous pars plana vitrectomy (PPV) in the management of severe myopia. This retrospective study comprised 14 eyes of eight patients who had RLE to treat myopia of −19.0±5.4 diopters (D). Phacoemulsification, posterior chamber intraocular lens (IOL) implantation, and standard three-port vitrectomy were performed. Mean postoperative follow-up time was 30 months (range 12-49). The postoperative best-corrected visual acuity (BCVA) was 0.68±0.23 compared to 0.37±0.24 preoperatively. There was no postoperative decrease in visual acuity in any eye. Mean postoperative spherical equivalent was −0.7 D (±1.6). At 30 months mean follow-up time, the spherical equivalents of nine eyes (64.3%) were within ±1 D of emmetropia. There was no significant change in astigmatism due to operative procedures. During the 30 months follow-up period three eyes (21.4%) required neodymium : yttrium-aluminium-garnet (Nd : YAG) capsulotomy for

Abstract PURPOSE: To report the outcomes of combined phacoemulsification and pars plana vitrectomy (PPV) to restore visual acuity in patients with cataract and posterior segment involvement secondary to chronic uveitis. SETTING: Ocular Immunology and Uveitis Service, Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, Massachusetts, USA. METHODS: This study comprised 34 patients (20 women, 14 men; 36 eyes) with posterior segment involvement secondary to chronic uveitis who had combined phacoemulsification and PPV from 1998 to 2002. The main outcome measures were visual acuity, intraocular pressure, and cystoid macular edema. RESULTS: The mean patient age was 45 years +/- 16.09 (SD). The mean duration of uveitis before surgery was 56 +/- 44.17 months. In 24 eyes (66.7%), an intraocular lens (IOL) was implanted during surgery; 12 eyes (33.3%) were left aphakic. Five eyes (13.8%) received an intraocular steroid injection intraoperatively. Visual acuity improved in 26 eyes (72.2%), ...

Pars plana vitrectomy for acute infectious endophthalmitis can be challenging due to severe inflammation in the anterior chamber creating significant media opacity. We describe a surgical technique co

At the time of the operation it may be necessary to perform additional treatments such as laser treatment. Laser treatment is often performed at vitrectomy in diabetic patients. The laser heats up and deliberately destroys some of the peripheral retina and this is thought to reduce the oxygen demands of the retina. This in turn reduces the drive for the new abnormal blood vessels to grow. This can even cause existing abnormal blood vessels to shrink. Laser treatment can affect the peripheral sight (see What are the possible side effects of vitrectomy below) and this may be considered to be a necessary consequence of efforts to try to protect the central sight.. If a tear occurs in the retina the surgeon may use freezing or further laser treatment to the retina to reduce the risk of retinal detachment (see What are the possible side effects of vitrectomy below). We may then put a gas or oil bubble in the eye to support the retina for a while. If we use a gas bubble, your normal body fluids ...

Promising early preclinical research currently underway at the University of Louisville could lead to the elimination of a second surgery now commonly needed after retinal surgery.. Shlomit Schaal, M.D., Ph.D., associate professor, Department of Ophthalmology and Visual Sciences, and director of Retina, the Retina Fellowship Program in Vitreo-Retinal Diseases and Surgery and the Diabetic Retinopathy Service, Kentucky Lions Eye Center, is working with Martin OToole, Ph.D., assistant professor, Department of Bioengineering, on the project which is funded by the Coulter Translational Research Partnership at UofL.. The two are studying a new way for patients undergoing retinal surgery - known as vitrectomy - to avoid the need to have subsequent surgery to remove cataracts that develop. During vitrectomy surgery, vitreous gel is removed from the eye; it is this gel that protects the natural crystalline lens from damage caused by free radicals of oxygen.. With the gel loss during surgery, free ...

How is a macular hole treated?. In rare cases, a macular hole closes on its own. In severe cases (Stage 3 & 4), doctors will perform vitrectomy surgery. They remove the vitreous gel/fibrous membrane responsible for the pulling causing the macular hole. A temporary gas bubble is placed in the eye to seal the hole. The bubble is then absorbed by the body over 10 - 14 days and is replaced by saline produced naturally by the eye. The gas bubble then puts pressure on the macula, causing the hole to flatten and close. Part of the recovery involves lying face down for several days.. The technique uses a dye (indocyanine green or brilliant blue) and an instrument developed by Yasuo Tano in Japan made from micro diamond dust allows the tissue causing the macular hole to be removed. The success rates is greater than 95%.. Another condition that could lead to macular hole is Vitreomacular Traction Syndrome (VMT). Macular holes caused by VMT are treated with Ocriplasmin, a recombinant protease with activity ...

Vitrectomy is the surgical removal of the vitreous gel from the middle of the eye. It may be done when there is a retinal detachment, because removing the vitreous gel gives your ophthalmologist better access to the back of the eye. The vitreous gel may also be removed if blood in the vitreous gel does not clear on its own.. During a vitrectomy, the surgeon inserts small instruments into the eye, cuts the vitreous gel, and suctions it out. After removing the vitreous gel, the surgeon may treat the retina with a laser, 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. At the end of the surgery, silicone oil or a gas is injected into the eye to replace the vitreous gel and restore normal pressure in the eye.. A vitrectomy may be done to:. ...

In the endophthalmitis group, patients ranged from 5 to 85 years of age and showed varied etiologies. Retinal detachment was present in 5 eyes, which received silicone oil tamponade. Mean preoperative logMAR visual acuity (VA) was 2.29 ± 0.45, which improved to 1.10 ± 0.72 at 3 months postoperatively (p,0.001). Trauma cases ranged from 21 to 75 years of age. Retinal detachment was present in 9 out of 10 eyes, all of which received silicone oil tamponade. Preoperative logMAR VA was 2.26 ± 0.71, which improved to 1.33 ± 0.50 postoperatively (p,0.001). At 3 months postsurgery, the retina was attached in all eyes in both groups.. ...

To report the multimodal imaging and histology of a case of metastatic esophageal cancer with vitreoretinal involvement resembling acute retinal necrosis (ARN) in a patient receiving systemic chemotherapy. A 69-year-old Japanese man with a history of stage 4 esophageal carcinoma, treated with three cycles of 5-fluorouracil (5-FU) and cisplatin (CDDP) chemotherapy as well as 30 sessions of radiation therapy, presented with new onset of blurry vision in the right eye (OD). Visual acuity was 20/200 OD. Fundus examination OD revealed 2+ nuclear cataract, veil-like vitreous opacity, a tractional retinal detachment, and white retinal lesions in the macula and periphery masquerading as an ARN. Due to the poor view and uncertainty regarding diagnosis, combined cataract extraction and 25 gauge pars plana vitrectomy was performed. Polymerase chain reaction and cytologic analysis were performed on the vitreous samples, which was negative for all infectious entities but positive for poorly differentiated malignant

The macula is the part of the retina responsible for acute central vision, the vision you use 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 gas bubble to push against the macula and close the hole. The gas bubble will gradually dissolve, but the patient must maintain a face-down position for one to two weeks to keep the gas ...

4SB Beyoğlu Göz Eğitim ve Araştırma Hastanesi Klinik Şefi, İstanbul, Prof. Dr. Purpose: To present the results of the technique in which triamcinolone assisted internal limiting membrane (ILM) peeling during pars plana vitrectomy (PPV) for idiopathic macular hole.. Materials and Methods: 0.1-0.2 ml triamcinolone (Kenakort 40 mg), diluted 1:5, was carefully injected over the macular area under the fluid following core vitrectomy via standard 3-port sclerotomy in 11 patients (4 female, 7 male; mean age 67±8 years). ILM was peeled by using a forceps over the retinal surface in the form of maculorhexis while triamcinolone made ILM visible by specifically adhering it. C3F8 gas was used as internal tamponade at the end of surgery. Anatomic success was assessed by the help of optical coherence tomography and functional success was assessed by using Snellen visual acuity charts. Snellen visual acuity values were converted to logMAR equivalents for the statistical comparisons.. Results: Mean ...

The design of this study is a prospective, consecutive, observational case series of 144 patients with primary rhegmatogenous retinal detachment (RRD), with a minimun follow-up of 12 moths. We describe a new classification system of the intraocular tamponade volume, which allows a systematic determination of the gas volume in the vitreous cavity following pars plana vitrectomy (PPV). This classification pretends to unify the different criteria of the retinal specialists, as well as serve as a tool to analyse the different factors that determine the volume of the gas tamponade in the vitreous cavity following PPV. In the present series, we identify the status of the crystalline lens (phakic vs pseudophakic) and the extension of the vitrectomy (measured as the number of quadrants of the vitreous base dissected during PPV) as the main factors that determine the volume of the gas tamponade in the vitreous cavity following PPV. This report evaluates the correlation between serial microstructural ...
