Purpose To evaluate the long-term visual prognosis and intraocular pressure (IOP) control following direct and indirect cycloplexy for the surgical treatment of traumatic cyclodialysis clefts. Methods Retrospective consecutive case series of 17 eyes of 17 patients. All eyes showing signs of ocular hypotony were treated with either cleft cyclocryotherapy and/or direct surgical cycloplexy. Cycloplexy was performed by directly suturing the ciliary body to the scleral spur under a double-lamellar limbal-based scleral flap. The main outcome measures were IOP, best-corrected visual acuity (BCVA), and the occurrence of postoperative complications. Results The cyclodialysis clefts were post-traumatic in all the 17 eyes and extended for 2.1 ± 1.6 clock-hours (range, 0.5-6 clock-hours). The mean follow-up time was 43.7±24.6 months (range, 12-110 months). Preoperatively, the mean IOP was 6.9±4.0 mm Hg (range, 2-14 mm Hg). Postoperatively, painful reversible IOP spikes of up to 70 mm Hg developed in 13 eyes. The final mean postoperative IOP was 12.2 ± 4.1 mm Hg with no cases of secondary glaucoma. Preoperatively, BCVA was 6/12 or better in 4 eyes (24%), which rose to 12 eyes (71%) at final follow-up. Of the 12 patients who underwent direct cycloplexy, 75% achieved a final BCVA of 6/12 or better. There were no serious complications related to direct cycloplexy, including suprachoroidal haemorrhage or endophthalmitis. Conclusions Successful cyclodialysis cleft repair can lead to a good long-term visual prognosis and stable IOP control, even in cases with a protracted history of ocular hypotony.
IntroductionPrimary open-angle glaucoma is estimated to affect 3% of the population aged 40–80 years. Trabeculectomy is considered the gold standard in surgical management of glaucoma; however, it is a technically complex procedure that may result in a range of adverse outcomes. Device-augmented, minimally invasive procedures (micro-invasive glaucoma surgeries, MIGS) have been developed aiming for safer and less invasive intraocular pressure (IOP) reduction compared with traditional surgery.MethodsThis paper presents results from a systematic literature review conducted in accordance with National Institute for Health and Care Excellence requirements for the Medical Technology Evaluation Programme via multiple databases from 2005 to 2016. For clinical outcomes, randomized clinical trials (RCTs) comparing MIGS with trabeculectomy or other therapies, observational studies, and other non-RCTs were included. Clinical outcomes reviewed were the change from baseline in mean IOP levels and change in topical glaucoma medication. Safety was assessed by reported harm and adverse events. For economic evidence, trials on cost-effectiveness, cost-utility, cost-benefit, cost-consequences, cost-minimization, cost of illness, and specific procedure costs were included. Risk of bias was assessed for clinical studies using the Cochrane Risk of Bias tool.ResultsA total of nine RCTs (seven iStents®, one Hydrus®, and one CyPass®), seven non-RCTs (three iStent®, three CyPass®, and one Hydrus®), and 23 economic studies were analyzed. While various forms of trabeculectomy can achieve postoperative IOP of between 11.0 and 13.0 mmHg, MIGS devices described in this review were typically associated with higher postoperative IOP levels. In addition, MIGS devices may result in increased hypotony rates or bleb needling in subconjunctival placed devices, requiring additional medical resources to manage. There is limited available evidence on the cost-effectiveness of MIGS and therefore it remains unclear whether the cost of using MIGS is outweighed by cost savings through decreased medication and need for further interventions.ConclusionLarger randomized trials and real-world observational studies are needed for MIGS devices to better assess clinical and economic effectiveness. Given the shortage of published data and increasing use of such procedures, living systematic reviews may help to provide ongoing and timely evidence-based direction for clinicians and decision makers. This review highlights the current unmet need for treatments that are easy to implement and reduce long-term IOP levels without increasing postoperative aftercare and cost.FundingSanten GmbH, Germany.Electronic supplementary materialThe online version of this article (10.1007/s40123-018-0131-0) contains supplementary material, which is available to authorized users.
Some individuals with keratoconus are at high risk of developing acute corneal hydrops. These patients could be managed more aggressively to reduce their risk of developing this complication of their disease.
Variations in defining postoperative hypotony can have a large impact on the reported success and failure rates among studies. There is a need for a more robust universal definition, focusing on clinically important signs, to allow better comparison between different treatment modalities.
Purpose To evaluate current practice of transscleral diode laser cyclophotocoagulation (cyclodiode) laser treatment among consultant ophthalmologists in the United Kingdom. Methods A 31-question survey was emailed to all practising consultant ophthalmologists who were members of the Royal College of Ophthalmologists. All non-responders were sent a postal version of the questionnaire. This paper looked at cyclodiode practice patterns and consisted of questions on demographic data, transillumination, and power settings, factors influencing practice, post-operative care, and repeat treatment. Results A total of 510 participants (53.6%) responded. A total of 180 (35.3%) responders reported performing cyclodiode laser treatment, of which 84 (46.7%) were glaucoma subspecialists (GSS). Initial median power settings used were 1500 mW and 2000 ms. The average number of applications delivered per sitting was 25.5 ± 1.2 applications for GSS vs 20.6 ± 2.0 for non-GSS in a seeing eye (P ¼ 0.0013). In all, 65% routinely transilluminated the globe of which 78% were GSS and 52.3% were non-GSS (P ¼ 0.0009). In all, 43% of the GSS vs 17% of the non-GSS lowered power settings in uveitic glaucoma (P ¼ 0.013). In blind eyes, 30% of the GSS vs 12% of the non-GSS increased energy levels (P ¼ 0.0014). In all, 60% of the responders performed cyclodiode at any visual acuity, whereas 22% performed combined cyclodiode and cataract surgery. Conclusions This survey highlights a wide variation in the use of cyclodiode laser treatment amongst GSS and non-GSS. However, the most frequently used practice may not be the optimal practice. A more individualised parameter according to the condition of the eyes may optimise the outcome.
Background/aimsTo evaluate the efficacy and safety of the PreserFlo MicroShunt glaucoma device in a multicentre cohort study.MethodsAll consecutive patients who received the microshunt with mitomycin-C (MMC) 0.4 mg/mL from May 2019 to September 2020 in three UK tertiary centres. Primary outcome at 1 year was a complete success, with failure defined as intraocular pressure (IOP) >21 mmHg or <20% reduction, IOP≤5 mmHg with any decreased vision on two consecutive visits, reoperation or loss of light perception vision. Secondary outcomes were IOP, best-corrected visual acuity, medications, complications, interventions and reoperations. We also performed subgroup analyses for severe glaucoma and assessed risk factors for failure.Results104 eyes had 1-year follow-up. Complete and qualified success at 1 year were achieved in 51.9% (N=54) and 16.4% (N=17), respectively, and failure occurred in 31.7% (N=33). There was a significant reduction in IOP (mmHg) from preoperatively (23.4±0.8, N=104) to 12 months (14.7±0.6, N=104) (p<0.0001). Antiglaucoma medications also decreased from preoperatively (3.4±0.1, N=104) to 12 months (0.7±0.1, N=104) (p<0.0001). Multivariate analyses showed an association between higher mean deviation and failure (HR 1.055, 95% CI 1.0075 to 1.11, p=0.0227). Complications were hypotony (19.2%; N=20), choroidal detachments (10.6%; N=11), hyphaema (5.8%; N=6) and bleb leak (5.8%; N=6). Needling and 5-fluorouracil injections were performed in 12.5% (N=13) and 33.7% (N=35), respectively, and 11.5% (N=12) required revision surgery.ConclusionThe PreserFlo MicroShunt with MMC 0.4 mg/mL showed an overall success rate of 68.3% at 1 year, and led to significant IOP and medication reduction with a low rate of adverse effects.
