Scleral Patch Graft Cpt Code
CPT is a registered trademark of the American Medical. Code 66160 reports a sclerectomy using a punch or scleral scissors. A topical antibiotic or pressure patch may be applied. Report 66180 if the procedure includes a graft.
An alternative to pharmacotherapies for the treatment of POAG is argon laser trabeculoplasty. Laser Trabeculoplasty is a surgical procedure in which a sharply focused beam of light is used to treat the drainage angle of the eye, enabling fluid to flow out of the front part, decreasing pressure.
Although this procedure is frequently used and well- tolerated, there are some concerns regarding its long-term effectiveness. Stein and Challa (2007) stated that laser trabeculoplasty has been reported to be an effective method to lower IOP in patients with primary or secondary OAG, both as an initial therapy or in conjunction with hypotensive medications. These investigators described the proposed mechanisms of action of argon laser trabeculoplasty and selective laser trabeculoplasty, as well as reviewed current studies of the therapeutic effect of these interventions. The exact mechanisms by which argon laser and selective laser trabeculoplasty lower IOP are unclear; the authors discussed the 3 most common theories:. the mechanical theory,. the cellular (biologic) theory, and.
the cell division theory.Since both lasers are applied to the same tissue and produce similar results, they most likely produce their effects in comparable ways. These researchers also described the results of several studies comparing these devices. Most show them to be equally effective at lowering IOP; however, there are a few circumstances when selective laser trabeculoplasty may be a better option than argon laser trabeculoplasty. The authors concluded that argon laser and selective laser trabeculoplasty are safe and effective procedures for lowering IOP. They noted that results of ongoing clinical trials will help further define their role in the management of patients with OAG.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. The Singapore Ministry of Health's guideline on glaucoma stated that laser trabeculoplasty may be used as an adjunct to medical therapy. Furthermore, the American Academy of Ophthalmology (AAO)'s guideline on POAG (2005) stated that laser trabeculoplasty is an appropriate initial therapeutic alternative (e.g., patients with memory problems or are intolerant to the medication).
When medications and/or laser trabeculoplasty have failed to reduce IOP, the most commonly used surgical intervention for POAG in adults is known as a filtering procedure. Filippopoulos and Rhee (2008) reviewed recent advances in penetrating glaucoma surgery with particular attention paid to 2 novel surgical approaches:. ab interno trabeculectomy with the Trabectome, and. implantation of the Ex-PRESS shunt.Ab interno trabeculectomy (Trabectome) achieves a sustained 30% reduction in IOP by focally ablating and cauterizing the trabecular meshwork/inner wall of Schlemm's canal. It has a remarkable safety profile with respect to early hypotonous or infectious complications as it does not generate a bleb, but it can be associated with early post-operative IOP spikes that may necessitate additional glaucoma surgery. The Ex-PRESS shunt is more commonly implanted under a partial thickness scleral flap, and appears to have similar efficacy to standard trabeculectomy offering some advantages with respect to the rate of early complications related to hypotony.
The authors concluded that penetrating glaucoma surgery will continue to evolve. The findings of randomized clinical trials will determine the exact role of these surgical techniques in the glaucoma surgical armamentarium.In a review on the use of novel devices for control of IOP, Minckler and Hill (2009) noted that Trabectome, Glaukos iStent, iScience (canaloplasty), and SOLX (suprachoroidal shunt) are newly developed surgical technologies for the treatment of OAG. 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. Trabectome and iStent are relatively non-invasive, aim to improve access of aqueous to collector channels and do not preclude subsequent standard surgery. SOLX potentially offers an adjustable aqueous outflow from the anterior chamber into the suprachoroidal space.An AAO's technology assessment on 'Novel glaucoma procedures' (Francis et al, 2011) noted that the SOLX gold shunt is limited to investigational use in the U.S. The disadvantages of the SOLX gold shunt are the presence of a permanent implant in the anterior chamber and suprachoroidal space with the risk of erosion or exposure, and that the mechanism of action is not well-delineated.

The assessment also stated that randomized controlled trials (RCTs) are needed to ascertain the effectiveness of procedures (including FUGO Blade goniotomy, iStent, and the SOLX gold shunt) compared with trabeculectomy, with one another, and with phacoemulsification alone (in the case of combined procedures).In a Cochrane review, Kirwan and colleagues (2009) evaluated the effectiveness of beta radiation during glaucoma surgery (trabeculectomy). These investigators searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (which includes the Cochrane Eyes and Vision Group Trials Register) (Issue 4 2008), MEDLINE (January 1966 to October 2008) and EMBASE (January 1980 to October 2008). The databases were last searched on 24 October 2008. They included randomized controlled trials comparing trabeculectomy with beta radiation to trabeculectomy without beta radiation. Data on surgical failure (IOP greater than 21 mm Hg), IOP, and adverse effects of glaucoma surgery were collected. Data were pooled using a fixed-effect model. These researchers found 4 trials that randomized 551 people to trabeculectomy with beta irradiation versus trabeculectomy alone - 2 studies were in Caucasian people (n = 126), 1 study in black African people (n = 320), and 1 study in Chinese people (n = 105).

People who had trabeculectomy with beta irradiation had a lower risk of surgical failure compared to people who had trabeculectomy alone (pooled risk ratio (RR) 0.23 (95% confidence interval CI: 0.14 to 0.40). Beta irradiation was associated with an increased risk of cataract (RR 2.89, 95% CI: 1.39 to 6.0). The authors concluded that trabeculectomy with beta irradiation has a lower risk of surgical failure compared to trabeculectomy alone. They stated that a trial of beta irradiation versus anti-metabolite is needed.Iridotomy, iridectomy or iridoplasty may be necessary for angle-closure glaucoma. Current guidelines (AAO, 2010) describe the indication for laser peripheral iridoplasty in the treatment of acute angle closure crisis (AACC) when laser iridotomy is not possible or if the AACC cannot be medically broken.
Iridectomy involves surgical removal of part of the iris of the eye. Iridoplasty is a procedure using laser energy to shrink the peripheral iris; also called gonioplasty. Iridotomy is a surgical procedure in which a laser is used to cut into the iris.However, there is insufficient evidence for the use of laser peripheral iridoplasty in the nonacute setting. In a Cochrane review, Ng and colleagues (2012) evaluated the effectiveness of laser peripheral iridoplasty in the treatment of narrow angles (i.e., primary angle-closure suspect), primary angle-closure (PAC) or primary angle-closure glaucoma (PACG) in non-acute situations when compared with any other intervention. In this review, angle-closure will refer to patients with narrow angles (PACs), PAC and PACG. These investigators searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 12), MEDLINE (January 1950 to January 2012), EMBASE (January 1980 to January 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to January 2012), the metaRegister of Controlled Trials (mRCT), ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP).
There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on January 5, 2012.
These researchers included only RCTs in this review. Patients with narrow angles, PAC or PACG were eligible. They excluded studies that included only patients with acute presentations, using laser peripheral iridoplasty to break acute crisis.
No analysis was carried out as only 1 trial (n = 158) was included in the review. The trial reported laser peripheral iridoplasty as an adjunct to laser peripheral iridotomy compared to iridotomy alone. The study reported no superiority in using iridoplasty as an adjunct to iridotomy for IOP, number of medications or need for surgery. The authors concluded that there is currently no strong evidence for laser peripheral iridoplasty's use in treating angle-closure.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.
Devices and procedures that have FDA clearance or are currently in phase III clinical trials in the United States were included: the Fugo blade (Medisurg Ltd., Norristown, PA), Ex-PRESS mini glaucoma shunt (Alcon, Inc., Hunenberg, Switzerland), SOLX Gold Shunt (SOLX Ltd., Boston, MA), excimer laser trabeculotomy (AIDA, Glautec AG, Nurnberg, Germany), canaloplasty (iScience Interventional Corp., Menlo Park, CA), trabeculotomy by internal approach (Trabectome, NeoMedix, Inc., Tustin, CA), and trabecular micro-bypass stent (iStent, Glaukos Corporation, Laguna Hills, CA). Literature searches of the PubMed and the Cochrane Library databases were conducted up to October 2009 with no date or language restrictions. These searches retrieved 192 citations, of which 23 were deemed topically relevant and rated for quality of evidence by the panel methodologist. All studies but 1, which was rated as level II evidence, were rated as level III evidence. All of the devices studied showed a statistically significant reduction in IOP and, in some cases, glaucoma medication use. The success and failure definitions varied among studies, as did the calculated rates. Various types and rates of complications were reported depending on the surgical technique.
On the basis of the review of the literature and mechanism of action, the authors also summarized theoretic advantages and disadvantages of each surgery. The authors concluded that the novel glaucoma surgeries studied all show some promise as alternative treatments to lower IOP in the treatment of open-angle glaucoma. It is not possible to conclude whether these novel procedures are superior, equal to, or inferior to surgery such as trabeculectomy or to one another. The studies provide the basis for future comparative or randomized trials of existing glaucoma surgical techniques and other novel procedures.The iStent (trabecular bypass device or microbypass implant) is a small heparin-coated, titanium implant, placed into Schlemm’s canal, intended to restore more normal fluid drainage and reduce IOP in individuals who are also undergoing cataract surgery. Schlemm’s Canal is a circular channel in the eye that collects aqueous humor from the anterior chamber and delivers it into the bloodstream.
CyPass Micro-Stent is a small drainage device inserted under goinioscopic view through a clear corneal incision using a retractable guidewire. Once in place, it is designed to directly connect the anterior chamber to the suprachoroidal space (between the sclera and choroid) to increase uveoscleral outflow, thereby purportedly decreasing IOP.

The iStent G3 Supra is a third generation iStent device under development and is similar in design to the CyPass Micro-Stent. 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.On June 25, 2012, the FDA approved the iStent Trabecular Micro-Bypass Stent System, Model GTS100R/L. This is the first device approved for use in combination with cataract surgery to reduce IOP in adult patients with mild or moderate open-angle glaucoma and a cataract who are currently being treated with medication to reduce IOP. The iStent, an anterior segment aqueous drainage device, is a small (approximately 1 mm by 0.5 mm) L-shaped titanium device that is inserted into the trabecular meshwork through the cornea and is designed to create a bypass between the anterior chamber and Schlemm's canal for aqueous humor to flow directly into the canal toward the episcleral drainage system.In a prospective, non-randomized, interventional case-series study, Buchacra et al (2011) evaluated the mid-term safety and effectiveness of the iStent glaucoma device in patients with secondary open-angle glaucoma. A total of 10 patients with secondary open-angle glaucoma (traumatic, steroid, pseudoexfoliative, and pigmentary glaucoma) of recent onset who underwent ab interno implantation iStent were included in this analysis. Patients were assessed following the procedure on days 1, 7, and 15 and months 1, 3, 6, and 12, and examinations included visual acuity, IOP measurement using Goldmann tonometry, number of glaucoma medications, and complications. Wilcoxon rank-test for data with abnormal distribution was used for the analysis of IOP and glaucoma medications at baseline versus 3, 6, and 12 months following the procedure.
The mean baseline IOP was 26.5 ± 7.9 (range of 18 to 40) mm Hg, and significantly decreased in 10.4 ± 9.2 mm Hg at 3 months (p 0.05); mean medications were 1.3 ± 1.0 and 1.4 ± 0.9, respectively (p 0.05). There was early and sustained IOP reduction, with 60% of controls versus 77% of micro-stent subjects achieving greater than or equal to 20% un-medicated IOP lowering versus baseline at 24 months (p = 0.001; per-protocol analysis).
