Combined Endoscope assisted Procedures (CEaP) as a complete treatment for neovascular glaucoma.

ABSTRACT:

Purpose

To investigate the effect and complications of Combined Endoscope assisted Procedures (CEaP): endoscopic cyclophotocoagulation and pars plana ablation (ECP-plus), along with endoscopic panretinal photocoagulation (PRP).

Patients and methods

The study design is a retrospective and noncomparative interventional case series from a tertiary referral center in Taiwan. Patients experiencing vessel growth at the iris and anterior chamber angle, along with an IOP > 21 mmHg were included.

Results

Twenty-five eyes from 23 patients were included over a 24-month period. After the procedures, all of them had a lower IOP value than their preoperative value. The mean IOP was 38.2± 7.1 mm Hg preoperatively, and 10.2± 4.7 mmHg (1 day), 13.8± 4.6 mmHg (1 week), 15.0± 5.3 mmHg (2 weeks), 17.4± 4.7 mmHg (1 month), 16.6± 4.1 mmHg (3 months), 16.0± 5.0 mmHg (6 months), and 15.7± 5.5 mmHg (12 months) postoperatively. At the 6th and 12th months, the IOP stabilized rate was 84% and 75%, respectively. Complications in the initial postoperative period (< 3 months) included uveitis (24%), and hyphema (16%), which were both resolved in the early postoperative period. Complications beyond 6 months included hypotony and phthisis bulbi in two patients (8%) in our study. There was no subject who suffered from retinal detachment, endophthalmitis or any other severe complications.

Conclusions

The results of this study show that CEaP offers positive results in IOP lowering and NV regression. Additionally, CEaP is a complete treatment for NVG in controlling IOP and NV growth. The IOP lowering effects can be sustained upon completion of the treatment.

Project description:BACKGROUND:Neovascular glaucoma (NVG) is a potentially blinding secondary glaucoma. It is caused by the formation of abnormal new blood vessels which prevent normal drainage of aqueous from the anterior segment of the eye. Anti-vascular endothelial growth factor (anti-VEGF) agents are specific inhibitors of the primary mediators of neovascularization. Studies have reported the effectiveness of anti-VEGFs for the control of intraocular pressure (IOP) in NVG. OBJECTIVES:To compare the IOP lowering effects of intraocular anti-VEGF agents to no anti-VEGF treatment, as an adjunct to existing modalities for the treatment of NVG. SEARCH METHODS:We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 12), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE, (January 1950 to January 2013), EMBASE (January 1980 to January 2013), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to January 2013), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov/) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 11 January 2013. SELECTION CRITERIA:We included randomized controlled trials (RCTs) and quasi-RCTs of people treated with anti-VEGF agents for NVG. DATA COLLECTION AND ANALYSIS:Two authors independently assessed the search results for trials to be included in the review. Discrepancies were resolved by discussion with a third author. Since no trial met our inclusion criteria, no assessment of risk of bias or meta-analysis was undertaken. MAIN RESULTS:No RCTs were found that met the inclusion criteria for this review. Two RCTs of anti-VEGF agents for treating NVG were not included in the review due to the heterogeneity and uncontrolled assignment of adjunct treatments received by the study participants. AUTHORS' CONCLUSIONS:Currently available evidence is insufficient to evaluate the effectiveness of anti-VEGF treatments, such as intravitreal ranibizumab or bevacizumab, as an adjunct to conventional treatment in lowering IOP in NVG. Well designed RCTs are needed to address this issue, particularly trials that evaluate long-term (at least six months) benefits and risks since the effects of anti-VEGF agents may be short-term only. An RCT comparing anti-VEGF agents with no anti-VEGF agents taking into account the need for co-interventions, such as panretinal photocoagulation (PRP), glaucoma shunt procedures, cyclodestructive procedures, cataract surgery, and deep vitrectomy, could be of use to investigate the additional beneficial effect of anti-VEGF agents in treating NVG. Since decisions for when and which co-interventions should be used are based on clinical criteria, they would not be appropriate for randomization. However, the design of a study on this topic should aim to balance groups by stratification of co-intervention at time of randomization or by enrolling a sufficient number of participants to conduct subgroup analysis by co-interventions (ideally 15 participants per treatment group for each subgroup). Alternatively, the inclusion criteria for a trial could limit participants to those who receive the same co-intervention.
