In such patients, their use topically can promote erythrocytic sickling within the chamber; their use orally can promote a sickling crisis. UGH syndrome is a severe complication of cataract extraction and a cause for blurry vision weeks to months after surgery. These include: Straining (during coughing, sneezing, vomiting, or while using the toilet) Injury to the head or eye, including infection. Further, the patient may develop glaucomatous atrophy and visual field loss. The term UGH Syndrome was originally described by Ellingson in 1977 as a result of excessive lens movement by small lens size or lens dislocation. The longer axial length and the shallow AC are associated risk factors [19]. In a study that sets the threshold at 28mmHg, the percentage in glaucomatous eyes was 46.4% versus 18.4% in nonglaucomatous [23]. Taking into consideration this fact, we need to adjust our strategy to the specifics of trabeculectomised patients. Pohjalainen T., Vesti E., Uusitalo R. J., Laatikainen L. Intraocular pressure after phacoemulsification and intraocular lens implantation in nonglaucomatous eyes with and without exfoliation. An increase in acute and sustained intraocular pressure can be a potential complication of this therapy. A patient performing the Valsalva maneuver or similar staining may cause a similar effect by raising EVP and causing reflux.

Abstract:. Careers, Unable to load your collection due to an error. Cases of UGH Syndrome were described even with an adequate positioning in the bag for a single block IOL with square edged haptics in specific situations, such as zonular latitude and plateau iris [11]. and transmitted securely. Hayashi K., Hayashi H., Nakao F., Hayashi F. Changes in anterior chamber angle width and depth after intraocular lens implantation in eyes with glaucoma. Mathew R. G., Parvizi S., Murdoch I. E. Success of trabeculectomy surgery in relation to cataract surgery: 5-year outcomes. WebWhen encountering recurrent hyphema as a late stage complication of cataract surgery keep uveitis-glaucoma-hyphema (UGH) syndrome in your differential. Glaucoma has been ranked as one of the most common causes of visual impairment in the adult population worldwide. Scanning electron micrograph showing material attached to the tip of a haptic lens. in their formulas include as predictors the preoperative IOP in combination with other parameters such as anterior chamber depth, lens thickness, gonioscopy score, and glaucoma status [39]. Cycloplegics such as atropine 1.0% or cyclopentolate 1.0% can be prescribed if patients have ciliary spasm or are photophobic. Speaking at the ASCRS 2016, Dr. Albert Cheung stated that UGH is a rare, but potentially devastating complication. In a review of 20 suspected cases, ultrasonic biomicroscopy showed the haptic in contact with the iris in 75% of the cases, extending to the ciliary body in 35% and to the pars plana in 10% of the cases [7]. Yasutani H., Hayashi K., Hayashi H., Hayashi F. Intraocular pressure rise after phacoemulsification surgery in glaucoma patients. In this syndrome, poorly positioned IOL haptics may chafe the iris, ciliary body or anterior chamber (in the case of an anterior segment IOL). However, steroid induced IOP rise might appear as early as 5 days before surgery and up to several weeks later [28]. Oops! A very similar but ab externo technique is micropulse cyclophotocoagulation laser. Furthermore it has shown to have reduced effectiveness in non-Caucasian patients and when combined with cataract surgery. Prior to the operation the functionality of the bleb should be checked, either by simply measuring the pressure and assessing its morphology or by using AS-OCT and UBM [45, 46]. An official website of the United States government. The UGH Syndrome is a triad that commonly occurs in adults, nonetheless it was reported a case of postoperative uveitis-glaucoma-hyphaema syndrome following pediatric cataract surgery [3]. Liu et al. These patients have uncomplicated cataract implants and return for episodes of blurry vision weeks to months after surgery.

Uveitis-Glaucoma-Hyphaema Syndrome After Posterior Chamber Intraocular Lens Implantation. 2. Ultrasound biomicroscopy in chronic pseudophakic ocular inflammation associated with misplaced intraocular lens haptics. As an optometrist working at a surgical center, one of my most important jobs is to coordinate care through referring doctors. Rahmatnejad K, Pruzan NL, Amanullah S, Shaukat BA, Resende AF, Waisbourd M, Zhan T, Moster MR. Surgical Outcomes of Gonioscopy-assisted Transluminal Trabeculotomy (GATT) in Patients With Open-angle Glaucoma. (2) The lateral wound edges should be sutured securely. If it is found to be malfunctioning and a combined bleb revision/phacoemulsification procedure should be planned [44, 47]. In eyes with extensive anterior synechiae, cataract surgery would be best combined with goniosynechiolysis, in order to separate the anterior synechiae from the trabecular meshwork and achieve more sufficient IOP control. UGH syndrome, uveitis, glaucoma, hyphema, cystoid macular edema, IOL, anti-VEGF Therapy. The combination of cataract surgery with trabeculectomy remains controversial, in terms of best timing of each operation. Berson F. G., Patterson M. M., Epstein D. L. Obstruction of aqueous outflow by sodium hyaluronate in enucleated human eyes. In contrast to the aforementioned techniques and devices, Xen45 and InFocus are bleb forming procedures. Melancia D., Abego Pinto L., Marques-Neves C. Cataract surgery and intraocular pressure. A Pilot Study was conducted in the Centre for Ophthalmology, University Eye Hospital, Eberhard Karls University of Tbingen, Germany to measure this condition in a more realistic manner, and aimed to evaluate the kinetic influences, in fast direction changes and at lateral end points, with a digital high-speed camera along with digital morphometric software for dynamic measurements of phakic intraocular lens movements. Classical teaching states that if the intraocular pressure remains >25 for >5 days in the setting of a complete hyphema, corneal blood staining and its associated vision loss is possible.9,10 Previous studies with traumatic hyphema have revealed that failure to clear past 50% within a week is associated with peripheral anterior synechiae.11 If the intraocular pressure cannot be adequately controlled, concern for glaucomatous optic atrophy increases and this should prompt a call to the surgeon. Parasympathomimetics should be avoided because of its miotic effect and increase in the mechanical chaffing to the iris. MIGS are essentially a category of procedures that offer a higher safety profile but lower efficacy than trabeculectomy. Fang E. N., Kass M. A. *Ophthalmology Department, Dr. 16404 Smokey Point Blvd. A case of delayed onset recurrent hyphema after iStent surgery. UGH Syndrome can also be characterized by chronic inflammation, secondary iris neovascularization, cystoid macular edema (CME). WebConclusion: The development of hyphema is not uncommon after PPV for patients with PDR without neovascularization of the iris or angles and NVG, and membrane removal is a risk factor for postoperative hyphema. Brown R. H., Zhong L., Whitman A. L., Lynch M. G., Kilgo P. D., Hovis K. L. Reduced intraocular pressure after cataract surgery in patients with narrow angles and chronic angle-closure glaucoma. Although electron microscopy did not show any deterioration of the haptic material, the decreased size of the lens might have caused the rotation. showed that early cataract operation has higher incidence of trabeculectomy failure, considering a period of two years gap between the two operations being the safest option of those studied. Imaging of trabeculectomy blebs using anterior segment optical coherence tomography. In patients with PXF, surgery might be demanding due to the zonular instability that many of these patients have. While this may look disheartening, the vast majority of patients were managed with drops and SLT and only seven ended up needing filtration surgery [59]. The .gov means its official. If left untreated, the IOP spikes in otherwise normal eyes might not be harmful for the visual fields according to clinical data [26], but for already compromised glaucomatous eyes, a significant albeit transient postoperative raise in IOP can be detrimental [27]. Possible explanations for this result were described as implantation position, looseness of the iris or fixation points, shifting haptic phenomenon, and gravity forces pulling the lenses. Malvankar-Mehta M. S., Fu A., Subramanian Y., Hutnik C. Impact of ophthalmic viscosurgical devices in cataract surgery. In this syndrome, poorly positioned IOL haptics may chafe the iris, ciliary body or anterior chamber (in the case of On top of that it was found to have a high reoperation rate of 37.7% [62]. Maintaining a stable chamber by viscoelastic infusion prior to removal of irrigation handpiece from the eye during surgery is considered to protect from anterior chamber collapse and choroidal effusion in very short eyes. Comparison of prednisolone acetate 1.0% and difluprednate ophthalmic emulsion 0.05% after cataract surgery: incidence of postoperative steroid-induced ocular hypertension. Randomized double-masked clinical trial. It seems clear that the postoperative inflammation induced by phacoemulsification is considered the main factor leading to bleb failure. 2021. In most cases of hyphema, no treatment is necessary. Additionally, preoperative high intraocular pressure was deemed as a bad prognostic factor, presumably owing to an already malfunctioning bleb [44]. Management of hyphema ranges from medical to surgical and aims to eliminate any potential complications as discussed above. Other sources of IOP spikes after cataract include surgical trauma, prolonged surgery, retained lens debris, iris pigment scattering, inflammation, and About 3 million Americans have glaucoma, which is estimated to have a direct medical cost of $2.9 billion. Very few patients developed IOP >30mmg at 24 hours postoperatively, although hypertension can last up to a week [8, 11, 20]. The timely management of hyphema ensures that hyphema does not affect the visual recovery or the final anatomical success. In order to avoid bleb scarring, it is advisable to wait for about two years after the trabeculectomy, if at all possible. In patients that had standalone GATT choroidal folds, CMO and IOP spikes were seen [58]. decentrations were greater than 0.5 mm in 14 (43%) of 32 eyes [9]. In eyes with end-stage glaucoma, it is safer to decrease bottle height and avoid keeping the phaco tip in the anterior chamber without active aspiration during surgery, so that IOP does not reach very high levels. In conclusion, it is important to know the severe effects, signs, and management course for UGH syndrome. R. H. Y. ASARIA , J. F. SALMON, Oxford - Electron microscopy findings on an intraocular lens in the uveitis, glaucoma, hyphaema syndrome. Tojo N., Otsuka M., Miyakoshi A., Fujita K., Hayashi A. A scleral flap incision technique reduces postoperative astigmatism but can increase the incidence of hyphema during the first day after cataract surgery. Azuara-Blanco A., Burr J. M., Cochran C., et al. with. Intermittent contact with the fragile vascular uveal tissue may then lead to chafing, erosion, and pigment dispersion; consequently, with signs of anterior uveitis and recurrent episodes of hyphaema, and raised intraocular pressure. WebThese patients have uncomplicated cataract implants and return for episodes of blurry vision weeks to months after surgery. On the downside, endoscopic surgery is a new skill for ophthalmologists that needs ad initio training, and the postoperative inflammation requires intensive anti-inflammatory drop regime. Tijunelis M. A., Person E., Niziol L. M., et al. Hanh M, Nguyen T. Uveitis-glaucoma-hyphaema syndrome. Centre for Ophthalmology. Similarly Francis et al. These patients have uncomplicated cataract implants and return for episodes of blurry vision weeks to months after surgery. Gaasterland D. E., Blackwell B., Ederer F., et al. Accessibility The preoperative IOP and biometric characteristics are the main predictors of the postoperative course of IOP. With the widespread adoption of clear corneal incisions during routine cataract surgery, little post-operative bleeding is expected during follow-up. The cohesive viscoelastics have larger molecular chains and are aspirated more easily, but may cause higher IOP spikes than the dispersive if not removed, although differences are not great [10]. A subconjunctival hemorrhage Toric lenses have indeed proven to improve refractive outcomes in glaucomatous patients [68], but it is more complex about premium lenses as they invariably either decrease contrast sensitivity or do not affect it at all. A Historical and Histopathological Review. Kojima, S., Inatani, M., Shobayashi, K., Haga, A., Inoue, T., & Tanihara, H. (2014). The angle configuration is the initial source of hypertension in such eyes, and the removal of the lens offers sufficient space for the iris to retract and increase the angle width. Glaucoma is considered a risk factor for the development of an IOP spike after cataract surgery, and this has been demonstrated by studies that show increased incidence of early postoperative increase in IOP in eyes with glaucoma in comparison to normal eyes. government site. Risk factors for steroid response among cataract patients. Corneal endothelium has demonstrated a good tolerance to bevacizumab for doses of up to 2.5 mg, but repeated intracameral injections may cause endothelial cell loss. intracapsular. The selected peak lens deviation images that were analyzed in the study revealed a low-lying lens position relative to the pupil center in nine of ten eyes. Kleonikos Tsakiris and George Kontadakis contributed equally to the manuscript. In this paper, we are reviewing the preoperative assessment, surgical options, the planning, and postoperative care. Some authors in fact have proposed the use of anterior segment optical coherence tomography (AS- OCT) [45] and ultrasound biomicroscopy (UBM) [46] to distinguish between well and not-so-well functioning blebs. Dr. Cheungs 10-years (2005-2015) retrospective chart review is the result of 249 patients who had been referred for evaluation for IOL reposition or exchange, 53 of them (56 eyes) having UGH at presentation [4].

Postoperative Hyphema in Cataract Surgery With Scleral Flap Technique. This prevents mobility of the flap on the scleral bed. A careful history and examination, as well as appropriate investigations can confirm the diagnostic. A randomized trial of a Schlemms canal microstent with phacoemulsification for reducing intraocular pressure in open-angle glaucoma. Issa et al. The parameters of the laser treatment were 20 spots, 50 m of diameters, 600 mW of power and 100 msec of time. Most hyphema are self-limited In case of terminal stage glaucoma patients care should be taken to avoid significant increasing of the intraoperative IOP. Poley B. J., Lindstrom R. L., Samuelson T. W., Schulze R. Intraocular pressure reduction after phacoemulsification with intraocular lens implantation in glaucomatous and nonglaucomatous eyes. Posterior capsule rupture, vitreous prolapse, and IOL placement in sulcus are considered risk factors for high IOP [12]. Neo Y. N., Panos G. D., Gatzioufas Z., Vergados A. Ab interno trabecular bypass surgery with iStent. Hyphema may be seen in up to 25% of trabeculectomy cases.4, The risk of hyphema for the above types of glaucoma procedures increases for cases of neovascular glaucoma or when neovascular membranes are found within the anterior segment of the eye.5 Risks of hyphema increase for those with bleeding disorders such as sickle cell anemia, Von Willebrand disease or hemophilia. Uveitis-Glaucoma-Hyphaema Syndrome (UGH syndrome, or Ellingson Syndrome) is a rare condition caused by the mechanical trauma of an intraocular lens malpositioned over adjacent structures (iris, ciliary body, iridocorneal angle), leading to a spectrum of iris transillumination defects, microhyphaemas and pigmentary dispersion, concomitant with elevated intraocular pressure (IOP). Most studies agree that if preoperative IOP is more than 20mmHg, the IOP reduction after cataract surgery would be likely significant. Surv Ophthalmol. Cataract surgery can help reduce the intraocular pressure alone or combined with MIGS. You might feel sensitive to light or have pain, redness, and vision problems. In eyes with primary open angle glaucoma, no special technique modifications are needed usually. This article is only available in the PDF format. Privacy Policy| When combined with phacoemulsification, it reduced the eye pressure from a mean of 23.9mmHg to 15.5mmHg and drop dependency from 2.9 to 1.0 during the first 12 months of follow-up. It has also been proven to lower the intraocular pressure in open angle patients even when performed as standalone. Suite 303Arlington, WA 98223, 1412 S.W. Out of 259 surveys, the IOL Explantation indications given at ASCRS & ESCRS 2000 were the following: ACIOL & Iris fixated lenses (PBK with corneal decompensation, UGH syndrome with CME), Older PCIOL & PMMA PCIOL (Decentration, Corneal edema and inflammation), Foldable 3pc monofocal silicone PCIOL (40% incorrect lens power 32% decentration, 9% damaged IOL during insertion), Foldable 3 on acrylic PCIOL (39% incorrect lens power, 24% optical aberration, 15% decentration), Foldable plate-haptic silicone PCIOL (> 50% decentration, 22% incorrect lens power, 18% damaged IOL during insertion), Foldable 3 on multifocal silicone PCIOL (89% optical aberration, 11% others). The IOP after surgery can raise for several reasons, with the most common being the retained viscoelastic. Neovascularization of the iris or corneal edema (apposition of the prolapsed intraocular lens over the corneal endothelium) can also be included as other features. MD. 63, 94 This mechanism should be considered in patients with a history of ocular surgery who present with spontaneous The most usual clinical scenario is mild to moderate glaucoma which is either uncontrolled by drops or aims to reduce drops dependency, usually due to compliance issues pertaining to individual patient factors such as lifestyle, frailty, and drop side effects among others [49]. A. distribution, and reproduction in any medium, provided the original work A careful history and examination, as well as appropriate investigations can confirm the diagnostic. Avoidance of postoperative IOP spikes would protect many glaucomatous eyes from loss of visual fields, and timely use of cataract surgery could reduce the need for IOP lowering medication. When performed in patients with glaucoma, it can transiently increase the intraocular pressure and later on decrease the IOP to levels lower than the postoperative. Moreover it is still widely thought that cataract surgery following trabeculectomy will increase the risk of bleb failure [40] in spite of studies claiming otherwise [40, 41]. These characteristics could become risk factors that cause the decreased vision post-op. A suture within 2 mm of each wound extremity will assure tightness. HHS Vulnerability Disclosure, Help Crowell EL. Removal of the crystalline lens and placement of a much thinner intraocular lens in all operated eyes lead to deepening of the anterior chamber and increase in angle width, an effect with increased clinical significance in eye with narrow preoperative angles. New England Medical Center Grand Rounds, Tufts University. 2002 Jul-Aug;47(4):297-334. Apart from these reasons that lead to IOP raising up to 2 days postoperatively, there is a late postoperative risk of IOP rise due to steroid use after cataract surgery [28, 29]. In fact it showed superiority over the iStent when combined with cataract surgery. Phi K. Uveitis-Glaucoma-Hyphaema (UGH) Syndrome - A Complex Complication.
