Excimer Laser Trabeculotomy

Abstract Background Excimer laser trabeculotomy (ELT) is a minimally invasive procedure to lower the intraocular pressure (IOP) via a photo-ablative laser that is applied to the trabecular meshwork. With this procedure, it is possible to improve the outflow of the aqueous humor. Until now, a limited number of studies examining mostly relatively small sample sizes with midterm follow-up exist. We therefore present the analysis of a large ELT cohort in a long-term follow-up. Methods We recorded data from 580 patients who underwent ELT or combined ELT with cataract surgery at our institution from November 2000 until March 2011. A total of 512 patients with primary open angle glaucoma (POAG), pseudoexfoliation glaucoma (PEX), and ocular hypertension (OHT) were included in the analysis. At every follow-up examination, the usage of IOP-lowering medication and the IOP were recorded. Failure criteria were defined as the need for another surgical glaucoma procedure, when the IOP was not 21 mmHg or less and a reduction of 20% from the baseline was not achieved with (qualified success) or without (absolute success) additional medication. Statistical analysis was done using Kaplan-Meier analysis and Cox regression. Results Four hundred twenty-eight patients underwent combined cataract and ELT surgery, and 84 underwent solitary ELT surgery. After a median follow-up time of 656 days, 87% (combined surgery) and 66% (ELT) of the patients did not have to undergo another IOP-lowering intervention; 47/31% were classified as a qualified success and 31/11% as a complete success. The IOP-lowering medication, however, could not be significantly reduced within that time period. Conclusion Especially when combined with cataract surgery, ELT is a feasible minimally invasive procedure to lower the IOP on a mid- to long-term basis. Over the long term, however, IOP-lowering medication could not be reduced.

ABSTRACT Aim In this study, we reviewed demographics and biometric characteristics among patients receiving chronic β-blockers and prostaglandins (PGs) for primary open-angle glaucoma. We compared the age at the time of cataract surgery in different patient groups and in a control group which was not under any medication. Materials and methods Retrospective chart review of glaucomatous patients who underwent cataract extraction at the Department of Ophthalmology of the University Hospital of Heraklion, Crete, Greece, between January 1998 and December 2016 was done. Age at cataract surgery, axial length (AL), and preoperative and postoperative best-corrected visual acuities (BCVAs) were recorded. A cohort of patients without glaucoma who were operated for cataract extraction was also evaluated. Results In all, 320 patients were reviewed. There were significant results in mean age difference between the beta-antagonist and the PG group [3.05 years, 95% confidence interval (CI) 1.54-4.57] and between the beta-antagonist group with the patients receiving a combined therapy (3.02 years, 95% CI 1.14-4.91). No significant difference was found between the PG and the combination group. All the three treated groups had a significant lower mean age than the control group at the time of cataract surgery. Conclusion Based on our study, we concluded that there might be a possible association between chronic treatment with beta-antagonist agents and earlier cataract surgical time in the treated eye. Clinical significance Intraocular pressure control is often usually achieved using ophthalmic agents. Their topical and systemic effects should be monitored precisely. Earlier cataract formation might be an important side effect which the physician has to keep in mind before choosing the suitable medication.

Abstract OBJECTIVE To identify complications associated with and short- and long-term outcomes of surgical intervention for treatment of esophageal foreign bodies (EFBs) in dogs. ANIMALS 63 client-owned dogs. PROCEDURES Patient records from 9 veterinary hospitals were reviewed to identify dogs that underwent surgery for removal of an EFB or treatment or an associated esophageal perforation between 2007 and 2019. Long-term follow-up data were obtained via a client questionnaire. RESULTS 54 of the 63 (85.7%) dogs underwent surgery after an unsuccessful minimally invasive procedure or subsequent evidence of esophageal perforation was identified. Esophageal perforation was present at the time of surgery in 42 (66.7%) dogs. Most dogs underwent a left intercostal thoracotomy (37/63 [58.7%]). Intraoperative complications occurred in 18 (28.6%) dogs, and 28 (50%) dogs had a postoperative complication. Postoperative complications were minor in 14 of the 28 (50%) dogs. Dehiscence of the esophagotomy occurred in 3 dogs. Forty-seven (74.6%) dogs survived to discharge. Presence of esophageal perforation preoperatively, undergoing a thoracotomy, and whether a gastrostomy tube was placed were significantly associated with not surviving to discharge. Follow-up information was available for 38 of 47 dogs (80.9%; mean follow-up time, 46.5 months). Infrequent vomiting or regurgitation was reported by 5 of 20 (25%) owners, with 1 dog receiving medication. CLINICAL RELEVANCE Results suggested that surgical management of EFBs can be associated with a high success rate. Surgery should be considered when an EFB cannot be removed safely with minimally invasive methods or esophageal perforation is present.

Object A relatively benign natural course of unruptured cerebral arteriovenous malformations (AVMs) has recently been recognized, and the decision to treat incidentally found AVMs has been questioned. This study aims to evaluate the long-term imaging and clinical outcomes of patients with asymptomatic, incidentally discovered AVMs treated with Gamma Knife surgery (GKS). Methods Thirty-one patients, each with an incidentally diagnosed AVM, underwent GKS between 1989 and 2009. The nidus volumes ranged from 0.3 to 11.1 cm3 (median 3.2 cm3). A margin dose between 15 and 26 Gy (median 20 Gy) was used to treat the AVMs. Four patients underwent repeat GKS for still-patent AVM residuals after the initial GKS procedure. Clinical follow-up ranged from 24 to 196 months, with a mean of 78 months (median 51 months) after the initial GKS. Results Following GKS, 19 patients (61.3%) had a total AVM obliteration on angiography. In 7 patients (22.6%), no flow voids were observed on MRI but angiographic confirmation was not available. In 5 patients (16.1%), the AVMs remained patent. A small nidus volume was significantly associated with increased AVM obliteration rate. Thirteen patients (41.9%) developed radiation-induced imaging changes: 11 were asymptomatic (35.5%), 1 had only headache (3.2%), and 1 developed seizure and neurological deficits (3.2%). Two patients each had 1 hemorrhage during the latency period (116.5 risk years), yielding an annual hemorrhage rate of 1.7% before AVM obliteration. Conclusions The decision to treat asymptomatic AVMs, and if so, which treatment approach to use, remain the subject of debate. GKS as a minimally invasive procedure appears to achieve a reasonable outcome with low procedure-related morbidity. In those patients with incidental AVMs, the benefits as well as the risks of radiosurgical intervention will only be fully defined with long-term follow-up.

Abstract BACKGROUND: Section of a tight filum terminale is a minimally invasive procedure compared with cord untethering procedures used for more complex spinal abnormalities. Anecdotal evidence suggests, however, that the risk of symptomatic retethering resulting from scarring might be higher than previously thought. OBJECTIVE: To determine the frequency of symptomatic retethering after section of a tight filum terminale and to explore possible risk factors. METHODS: We reviewed databases at 2 pediatric neurosurgery centers for all patients who had surgery for a suspected tight filum terminale between January 1982 and June 2009. RESULTS: We identified 152 patients. The median length of follow-up was 78 months. Thirteen patients (8.6%) went on to retether symptomatically at a median time of 23.4 months after the initial procedure. Eight had early retethering (within 2 years) and 5 had late retethering (after 7 years). Compared with late retetherers, early retetherers were older at initial surgery (median, 9.4 vs 0.9 years of age), had a higher level of the conus (median, L1/L2 vs L3/L4), had more arachnoiditis after initial surgery, and required more repeat untethering procedures. Late retetherers were younger at initial surgery than those who did not retether (median, 0.9 vs 4.5 years of age). CONCLUSION: Symptomatic retethering is not uncommon after a simple filum snip, and long-term follow-up is warranted. Two distinct patterns of retethering were observed. Arachnoiditis caused by infection or a cerebrospinal fluid fistula may predispose to early retethering, whereas early surgery for prevention of tethered cord symptoms may predispose to late retethering.
