Hypotensive medication use was tracked throughout the course of follow-up. These investigators noted that drawbacks to these studies included the lack of controls and washout IOP. The first-line drugs include timolol (a non-specific beta blocker) and latanoprost (a prostaglandin F2a agonist). San Francisco, CA: AAO; 2010. J Cataract Refract Surg. In the U.S. pivotal trial conducted in refractory glaucoma patients, XEN reduced IOP from a mean medicated baseline of 25.1 (+ 3.7) mmHg to 15.9 (+ 5.2) mmHg at the 12 month visit (n=52). Garcia-Feijoo J, Rau M, Grisanti S, et al. Arq Bras Oftalmol. These researchers analyzed the change in IOP and glaucoma medications using different MIGS devices (Trabectome, iStent, excimer laser trabeculotomy (ELT), iStent Supra, CyPass, XEN, Hydrus, Fugo Blade, Ab interno canaloplasty, Goniscopy-assisted transluminal trabeculotomy) as a solo procedure or in association with phaco-emulsification; RCTs and non-RCTs (non-randomized comparative studies, non-randomized study of intervention [NRS], and before-after studies) were included. The authors concluded that MIGS procedures offer reduction in IOP, decrease in dependence on glaucoma medications and an excellent safety profile. Found inside – Page 1120The costs to the patient and healthcare system of treatment for achronic disease, such as glaucoma arewell ... the US.8 While current implementations in the US allow more patients to cover the cost of their medication through insurance, ... The third-line drugs include apraclonidine (an alpha agonist), pilocarpine (a cholinergic agonist), acetazolamide (an oral carbonic anhydrase inhibitor), and epinephrine (a non-specific adrenergic agonist). This type of surgery is used to treat several types of glaucoma, including congenital glaucoma, neovascular glaucoma, and glaucoma caused by an injury. The electronic databases were last searched on January 5, 2012. Mean IOP was reduced from 19.42 ± 1.89 mm Hg to 16.26 ± 4.23 mm Hg (p = 0.002) at the end of follow-up, indicating a 16.33 % decrease in IOP. PLoS One. Franca et al (2014) developed and evaluated a novel sustained-release drug delivery system of bimatoprost (BIM). The authors concluded that ab interno trabeculectomy has a lower success rate than trabeculectomy. Defining success as IOP less than or equal to 21 with a 20 % decrease while avoiding re-operation, the overall average success rate after 2â years was 46 ± 34 %. Mean decrease from baseline was statistically significant at months 6 (p = 0.0188) and 12 (p = 0.0356). These investigators examined medical records of 242 consecutive eyes of 146 patients with uncontrolled IOP despite maximum tolerated medical therapy or prior surgical intervention that underwent XEN45 implantation (as sole procedure or in combination with CS) between March 2014 and June 2015. Ab interno trabeculectomy versus trabeculectomy for open-angle glaucoma. Though laser eye surgery is, as it sounds, an operation, it is not covered under private hospital insurance. Of 505 subjects, 131 were randomized to the control group and 374 were randomized to the micro-stent group. The presence of inflammatory cells, indicators of inflammation, and subsequent fibrosis in the conjunctival epithelium was not methodically investigated; however, it could provide a valuable predictive tool and deserved further investigations. Reitsamer H, Sng C, Vera V, et al; Apex Study Group. Aetna considers insertion of a drug-eluting implant, including punctal dilation and implant removal when performed, into the lacrimal canaliculus experimental and investigational for the treatment of glaucoma or ocular hypertension because its effectiveness has not been established. The pressure may be normal immediately after laser surgery and rise sharply within 1 to 4 hours after laser surgery. Barton K, Gedde SJ, Budenz DL, et al; Ahmed Baerveldt Comparison Study Group. Glaucoma is an eye condition that doctors use several tests to diagnose. At all post-operative visits among eyes without additional surgery or medication, greater than or equal to 91 % of eyes had greater than or equal to 20 % IOP reduction on 1 medication versus pre-operative medicated IOP. The findings emphasize the profound impact of race and type of health plan on the care of patients with OAG, the authors said, and they concluded that considerable efforts are needed to improve the quality and timeliness of glaucoma care for Medicaid recipients, especially those who are black and/or are members of other minority groups. Curr Opin Ophthalmol. Ophthalmology. } The SCS was imaged with OCT after micro-stent implantation at 1, 6 months, and 1 year. Literature searches of the PubMed and the Cochrane Library databases were conducted up to October 2009 with no date or language restrictions. The risks of performance and detection bias are unclear. 1996;15(1):7-13. Englert JA, Freedman SF, Cox TA. Overview of glaucoma in infants and children. After 12âmonths, there was a significant decrease in IOP and medications in the Hydrus group compared with baseline values. For AIT and phaco-AIT, the 1-year cumulative probability of success was 81 % and 87 %, respectively. Primary outcome was a 20 % or more decrease in IOP from medicated baseline at 1 year. The Ex-PRESS mini glaucoma shunt is a 400-micron diameter tube made from implantable stainless steel that is less than 3 mm long, and is loaded on a specially designed disposable inserter. A total of 79 studies were identified following a literature search adhering to PRISMA guidelines. Early post-operative hypotony and choroidal effusion were significantly more frequent after trabeculectomy compared with the Ex-PRESS implant under scleral flap (p < 0.001). 2010;19(1):24-30. Aust N Z J Ophthalmol. Kaplan-Meier survival curve analysis showed no significant difference in the success between the 2 groups (p = 0.594). The authors concluded that the Ex-PRESS implant under a scleral flap had similar IOP lowering efficacy with a lower rate of early hypotony compared with trabeculectomy. Found inside – Page 144Cost is a major issue in these countries along with poor availability of medications, lack of health insurance and ... use of prostaglandin analogues, changes in insurance coverage, and possibly more aggressive glaucoma treatment [8]. Blurry, cloudy vision from cataracts are a natural part of aging.Eye Doctors Performing Cataract Surgery in St Louis The good news is Pepose Vision can help. Overall eye health: If you have an existing condition, like dry eye syndrome, cataracts, glaucoma or another eye condition, you may not be a good candidate for LASIK. These include minimizing patient adherence problems, increasing QOL for patients with ocular toxicity, and potentially reducing lifetime costs of expensive glaucoma medications, all while preserving the conjunctiva if additional, more invasive glaucoma surgeries are necessary in the future. Nassiri N, Kamali G, Rahnavardi M, et al. TRICARE may cover the cost for the otherwise covered treatment of complications resulting from a non-covered surgery or treatment when the complication represents a medical … J Glaucoma. Samuelson TW, Katz LJ, Wells JM, et al; US iStent Study Group. Early post-operative hypotony was defined as IOP less than 5 mm Hg during the first post-operative week. Wang H, Cheng JW, Wei RL, et al. He had bilateral findings of elevated IOP, buphthalmos, Haab's striae, photophobia, and myopia. Costa VP, Azuara-Blanco A, Netland PA, et al.

Moreover, they stated that well-designed RCTs with extended follow-up are needed to evaluate the long-term effectiveness and late complications of these novel procedures. Cochrane Database Syst Rev. Medicare does cover Xen Gel Stent procedures when completed with or without cataract surgery. Two-year results of a multicenter study of the ab interno gelatin implant in medically uncontrolled primary open-angle glaucoma. A total of 4 RCCTs were selected for this meta-analysis, including 215 eyes of 200 patients (110 eyes in the Ex-PRESS group, 105 eyes in the trabeculectomy group). Galal A, Bilgic A, Eltanamly R, Osman A. XEN glaucoma implant with mitomycin C 1-year follow-up: Result and complications. TRICARE covers many eye surgeries and treatments. The authors concluded that XEN implant was an effective surgical treatment for POAG, with significant reduction in IOP and glaucoma medications at 1 year follow-up. In the secondary glaucoma group of 28 patients, IOP decreased by 17.2 mm Hg (SD, 10.8 mm Hg; 52.7 % [SD, 15.8 %]) with an average of 2.2 fewer glaucoma medications at 6 months. Vold S, Ahmed II, Craven ER, et al; CyPass Study Group. Ab interno trabeculectomy was performed using a dual-blade device; IOP was reduced from 28 to 15 mmHg in the left eye after 18 months. U.S. Food and Drug Administration (FDA). A number of publications reviewed the importance of the location of implantable devices, intra-operative gonioscopy, cost-effectiveness and quality-of-life studies, and randomized clinical trials. 62. Clinical Policy Bulletins are developed by Aetna to assist in administering plan benefits and constitute neither offers of coverage nor medical advice. OL LI { OL OL LI { National Institute for Health and Clinical Excellence (NICE). The synchronization between the 2 areas under observation had a definite learning curve. Medicare pays $1,431 of … Accessed November 11, 2005. Patients were followed for 24 months post-operatively. An alternative to pharmacotherapies for the treatment of POAG is argon laser trabeculoplasty. [Ex-PRESS miniature glaucoma implant inserted under a scleral flap in open-angle glaucoma surgery: A retrospective study]. Eye (Lond). Ann Intern Med. The authors concluded that these findings indicated that the XEN45 gel implant had a favorable safety profile and was an effective therapeutic option for controlling IOP in glaucoma patients with unregulated IOP despite IOP-lowering medical therapy or prior surgical intervention. The device is inserted under goinioscopic view through a clear corneal incision into the suprachoroidal space and is proposed for use alone or at the time of cataract surgery. Aetna considers the XEN Glaucoma Treatment System medically necessary for the management of refractory glaucoma, including cases where previous surgical treatment has failed, cases of primary open angle glaucoma, and pseudoexfoliative or pigmentary glaucoma with open angles that are unresponsive to maximum tolerated medical therapy. Wilson RP, Cantor L, Katz LJ, et al. The primary efficacy end-point examined the difference in mean change from baseline in diurnal IOPs (point estimate, 95 % CI] across 9 co-primary end-points at weeks 2, 6, and 12 comparing the BIM-arm with the TIM-arm using a non-inferiority margin of 1.5 mmHg. Payment will be expected from the patient if the insurance company fails to pay the claim within 45 days. The American Optometric Association's guideline on care of the patient with OAG (AOA, 2002; reviewed 2007) listed argon laser trabeculoplasty as an alternative to drug therapy for the management of patients with POAG. At Digit, the treatment for the same is included and covered under our daycare procedures – with no additional cost. J Glaucoma. A randomized trial of a Schlemm's canal microstent with phacoemulsification for reducing intraocular pressure in open-angle glaucoma. Aetna considers laser trabeculoplasty or Food and Drug Administration (FDA)-approved aqueous drainage/shunt implants medically necessary for the treatment of members with refractory primary open-angle glaucoma when first-line drugs (e.g., latanoprost or timolol), and second-line drugs (e.g., brimonidine or dorzolamide) have failed to control intra-ocular pressure (IOP). These new approaches to angle surgery have been demonstrated in preliminary case series to safely lower IOP in the mid-teens with far fewer complications than expected with trabeculectomy and without anti-fibrotics. Phacoemulsification versus phacoemulsification with micro-bypass stent implantation in primary open-angle glaucoma: Randomized double-masked clinical trial. In a retrospective case-series study, Fea and associates (2017b) examined the safety and efficacy of a new Schlemm canal scaffold microstent (Hydrus) combined with CS in routine clinical practice. The authors concluded that clinically relevant reduction in mean IOP was observed over 6 months with a BIM ocular insert and appeared to be safe and well-tolerated. Since SLT (Selective Laser Trabeculoplasty) is an FDA-approved treatment, it is typically covered by Medicare and medical insurance, with co-pays according to your policy. A total of 73 eyes of 73 patients with 1â year follow-up were identified.

For Cohort 1 (n = 23), mean ± SD IOP was 15.8 ± 3.8 mmHg after 24 months (change, -37 % ± 19 %). These investigators searched the Cochrane Central Register of Controlled Trials (CENTRAL; which contains the Cochrane Eyes and Vision Trials Register; 2020, Issue 7); Ovid Medline; Ovid Embase; the ISRCTN registry; ClinicalTrials.gov and the WHO ICTRP. 916 0 obj <> endobj McCartney and Phagura (2020) stated that microinvasive glaucoma surgery and its associated devices remain a field of continued interest and innovation in the management of patients with glaucoma. Saheb and Ahmed (2012) noted that there is an increasing interest and availability of micro-invasive glaucoma surgery (MIGS) procedures. The authors concluded that IOP was clinically and statistically significantly lower at 2 years in the Hydrus plus CS group compared with the CS alone group, with no differences in safety. In phaco-AIT, the mean IOP decreased 19 % from 20 ± 5.9â mmâ Hg and medications from 2.5 ± 1.5 to 1.6 ± 1.4 (n = 15). The authors concluded that the gelatin stent reduced IOP and medication use without raising unexpected safety concerns, offering a minimally invasive surgical option for refractory glaucoma patients. Canadian Agency for Drugs and Technologies in Health (CADTH). With a Medicare Advantage plan, you are entitled to all of the benefits covered under Original Medicare (the federal health insurance program), but they are provided by private insurance companies instead. It is unclear whether these results provided clinically significant health outcomes. A trabeculectomy is a kind of surgery to treat glaucoma. On behalf of the AAO, Francis and cooleagues (2011) reviewed the published literature and summarized clinically relevant information about novel, or emerging, surgical techniques for the treatment of open-angle glaucoma and described the devices and procedures in proper context of the appropriate patient population, theoretic effects, advantages, and disadvantages. Dupont G, Collignon N. New surgical approach in primary open-angle glaucoma: XEN gel stent a minimally invasive technique. Aqueous shunts for glaucoma. } Bio-distribution studies showed that the amount of 99mTc-BIM that remained in the eye was significantly lower after eye drop instillation than after chitosan insert implantation. Harvey MM, Schmitz JW. These are all considered to be medical problems and are covered by your major medical insurance plan. These researchers described the use of minimally invasive ab interno Kahook dual blade trabeculectomy for the treatment of primary congenital glaucoma. 2013;39(3):431-437. Data were pooled using a fixed-effect model. There is a low incidence of this occurring with all shunts currently available, and it occurs most frequently within a few millimeters of the corneo-scleral junction after anterior chamber insertion. Eur J Ophthalmol. In before-after series, MIGS surgery appeared effective in lowering both IOP and glaucoma drug use; MIGS showed a good safety profile: IOP spikes were the most frequent complications and no cases of infection or BCVA loss due to glaucoma were reported. Finally, images were not available for all subjects, with a gradual decrease in available images at later time-points. Deciding whether to have surgery for glaucoma can be hard. UpToDate [online serial]. Effectiveness end-points were greater than or equal to 20 % reduction from baseline in month 24 unmedicated DIOP and change in unmedicated month 24 DIOP from baseline. Additionally, nearly all of the current MIGS procedures have the potential risk of late failure due to scarring, and longer follow-up periods in future studies are needed to determine how the longevity of these MIGS procedures compares to the less than ideal longevity of selective laser trabeculoplasty. BIM-loaded inserts (equivalent to 9.0 µg BIM) were administered once into conjunctival sac, after ocular hypertension (OHT) confirmation. A second factor in not taking medication as prescribed is economics. Durr and colleagues (2020) (ELT is a MIGS that creates multiple laser channels through the trabecular meshwork using a cold laser system, which minimizes tissue fibrosis and aids in bypassing the main area of resistance to aqueous outflow. Hoh H, Grisanti S, Grisanti S, et al. 2011;5:527-533. de Jong LA. Subjects older than 18 years with co-existent uncontrolled mild or moderate open-angle glaucoma (including pseudoexfoliative and pigmentary) and cataract underwent phaco-emulsification and intra-ocular lens implantation along with ab-interno gonioscopically guided implantation of 1 Glaukos iStent. The surgeon makes a new opening in the colored part of the eye (iris). Mean medication use in controls decreased from 1.3 ± 1.0 drugs at baseline to 0.7 ± 0.9 and 0.6 ± 0.8 drugs at 12 and 24 months, respectively, and in the micro-stent group from 1.4 ± 0.9 to 0.2 ± 0.6 drugs at both 12 and 24 months (p < 0.001 for reductions in both groups at both follow-ups versus baseline).
