Background/Aim There is increasing evidence for using selective laser trabeculoplasty as a first line treatment for chronic open angle glaucoma. The current first-line treatment is pharmacological therapy using eye drops. This study aims to assess the outcomes of selective laser trabeculoplasty in patients with glaucoma and ocular hypertension at a district general hospital and consider its role in reducing cost and treatment burden when treating patients with these conditions. Methods A single centre, retrospective case-note audit involving 58 eyes from 31 patients with a minimum follow-up of 4 months. Results Post selective laser trabeculoplasty, 62% had intraocular pressure <20 mmHg on latest follow up (36/58 eyes). Post selective laser trabeculoplasty, 10 patients (32%) were prescribed one fewer topical medication, while 20 patients (65%) were prescribed the same number of topical medications. Only 1 patient (3%) was prescribed one additional topical medication. Conclusion Selective laser trabeculoplasty is a safe and effective option for managing glaucoma and ocular hypertension. Selective laser trabeculoplasty may represent a cost-effective solution for healthcare providers as compared to pharmacological treatment.

Background Newly diagnosed open-angle glaucoma (OAG) and ocular hypertension (OHT) are habitually treated with intraocular pressure (IOP)-lowering eyedrops. Selective laser trabeculoplasty (SLT) is a safe alternative to drops and is rarely used as first-line treatment. Objectives To compare health-related quality of life (HRQoL) in newly diagnosed, treatment-naive patients with OAG or OHT, treated with two treatment pathways: topical IOP-lowering medication from the outset (Medicine-1st) or primary SLT followed by topical medications as required (Laser-1st). We also compared the clinical effectiveness and cost-effectiveness of the two pathways. Design A 36-month pragmatic, unmasked, multicentre randomised controlled trial. Settings Six collaborating specialist glaucoma clinics across the UK. Participants Newly diagnosed patients with OAG or OHT in one or both eyes who were aged ≥ 18 years and able to provide informed consent and read and understand English. Patients needed to qualify for treatment, be able to perform a reliable visual field (VF) test and have visual acuity of at least 6 out of 36 in the study eye. Patients with VF loss mean deviation worse than –12 dB in the better eye or –15 dB in the worse eye were excluded. Patients were also excluded if they had congenital, early childhood or secondary glaucoma or ocular comorbidities; if they had any previous ocular surgery except phacoemulsification, at least 1 year prior to recruitment or any active treatment for ophthalmic conditions; if they were pregnant; or if they were unable to use topical medical therapy or had contraindications to SLT. Interventions SLT according to a predefined protocol compared with IOP-lowering eyedrops, as per national guidelines. Main outcome measures The primary outcome was HRQoL at 3 years [as measured using the EuroQol-5 Dimensions, five-level version (EQ-5D-5L) questionnaire]. Secondary outcomes were cost and cost-effectiveness, disease-specific HRQoL, clinical effectiveness and safety. Results Of the 718 patients enrolled, 356 were randomised to Laser-1st (initial SLT followed by routine medical treatment) and 362 to Medicine-1st (routine medical treatment only). A total of 652 (91%) patients returned the primary outcome questionnaire at 36 months. The EQ-5D-5L score was not significantly different between the two arms [adjusted mean difference (Laser-1st – Medicine-1st) 0.01, 95% confidence interval (CI) –0.01 to 0.03; p = 0.23] at 36 months. Over 36 months, the proportion of visits at which IOP was within the target range was higher in the Laser-1st arm (93.0%, 95% CI 91.9% to 94.0%) than in the Medicine-1st arm (91.3%, 95% CI 89.9% to 92.5%), with IOP-lowering glaucoma surgery required in 0 and 11 patients, respectively. There was a 97% probability of Laser-1st being more cost-effective than Medicine-1st for the NHS, at a willingness to pay for a quality-adjusted life-year of £20,000, with a reduction in ophthalmology costs of £458 per patient (95% of bootstrap iterations between –£585 and –£345). Limitation An unmasked design, although a limitation, was essential to capture any treatment effects on patients’ perception. The EQ-5D-5L questionnaire is a generic tool used in multiple settings and may not have been the most sensitive tool to investigate HRQoL. Conclusions Compared with medication, SLT provided a stable, drop-free IOP control to 74.2% of patients for at least 3 years, with a reduced need for surgery, lower cost and comparable HRQoL. Based on the evidence, SLT seems to be the most cost-effective first-line treatment option for OAG and OHT, also providing better clinical outcomes. Future work Longitudinal research into the clinical efficacy of SLT as a first-line treatment will specify the long-term differences of disease progression, treatment intensity and ocular surgery rates between the two pathways.

BackgroundThe determinants of success of selective laser trabeculoplasty (SLT) in treatment-naïve patients with open angle glaucoma (OAG) and ocular hypertension (OHT) have not been understood fully. Therefore, we have conducted this study to explore the predictors of success.MethodsThis is a retrospective review of a pre-existing database of patients who had received primary SLT at St Thomas’ Hospital, London, UK. Patients with OAG and OHT who had received primary 360° SLT treatment and had reliable baseline tonographic outflow facility (TOF) with minimum of 1 year of follow-up were included. Univariate and multivariate analyses were performed to find the determinants of success.ResultsOne hundred and seventy-four patients between August 2006 and February 2010 had received primary 360° SLT treatment and had baseline TOF measurement. Of these, 72 subjects fulfilled the eligibility criteria. In multivariate regression analysis, the only variable associated with success was baseline intraocular pressure (IOP) (R2=0.32, beta=−0.51, p<0.001, 95% CI −2.02 to −0.74).ConclusionTo our knowledge, this is the only study investigating the pretreatment TOF (measured with electronic Shiøtz tonography) and IOP as determinants of success 12 month’s post-360° SLT in treatment-naïve patients with OAG and OHT. This study demonstrated that pretreatment IOP (and not TOF) is the only determinant of success after primary SLT therapy.

Introduction: Uveitis can directly or indirectly lead to ocular hypertension which can lead to glaucoma. Ripasudil has a different mechanism of action than other anti-glaucoma medications available commercially and in contrary to these drugs, ripasudil also has anti-inflammatory properties providing an upper edge over other intraocular pressure lowering drugs. In addition to primary glaucoma, these new Rho kinase associated inhibitors can provide satisfactory results in glaucoma with secondary pathologies. Aim: To study the role of ripasudil as first line treatment for ocular hypertension in uveitis cases. Materials and Methods: A prospective randomised study comprising 40 patients of Ocular Hypertension (OHT) associated with uveitis was conducted in the Outpatient Department (OPD) of Ophthalmology at a tertiary care hospital in North India from October 2020 to January 2021. The diagnosis of uveitis was made clinically with detailed medical history and slit lamp biomicroscopic examination. All the diagnosed patients were started with topical ripasudil hydrochloride hydrate 0.4% eye drops twice daily along with anti-inflammatory medications. Intraocular Presure (IOP) was recorded after 4 weeks and 12 weeks at 8 am, 10 am and 4 pm. Effectiveness of the drugs was calculated in terms of mmHg fall in mean intraocular pressure using t-test and p-values. Results: Out of 40 patients with uveitis associated OHT, 20caseswere inflammation related (mean age was 56.2±16.3years,13 males, 7 females) and 20 cases were categorised as corticosteroid induced (mean age was 58.9±15.69 years, 14 males, 6 females). At 12 weeks there was 5.67±0.59 mmHg fall in IOP (22.70%) in inflammation related OHT and there was 6.37±0.07 mmHg fall in IOP (25.34%) in corticosteroid related OHT. There was statistically significant fall in IOP (p-value=0.001). Conclusion: This study demonstrated that topical ripasudil hydrochloride hydrate 0.4% eye drops is effective in lowering the IOP, also there were no side effects, so it is safe and well-tolerated. So, ripasudil can provide a safe and effective alternative for lowering of IOP among uveitis related OHT.

Background: The most common treatment for primary open-angle glaucoma (POAG) is the daily use of eye drops. Sustained-release drug delivery systems have been developed to improve patient adherence by achieving prolonged therapeutic drug concentrations in ocular target tissues while limiting systemic exposure. The purpose of this study is to compare the efficacy and safety of bimatoprost inserts with bimatoprost eye drops in patients with POAG and ocular hypertension (OH). Methods: We include OH and POAG patients aged between 40 and 75 years-old. Both OH and POAG patients had intraocular pressure (IOP) greater than 21 and ≤30 mmHg at 9:00 am without glaucoma medication and normal biomicroscopy. Five normal patients with IOP≤14 mmHg constitute the control group. A chitosan-based insert of bimatoprost was placed at the upper conjunctival fornix of the right eye. In the left eye, patients used one drop of LumiganTM daily at 10:00 pm. For statistical analysis, we used a two-way analysis of variance (ANOVA), Student t-test, and paired t-test. Results: Sixteen POAG and 13 OH patients with a mean age of 61 years were assessed. In both eyes, IOP reduction was similar during three weeks of follow-up (19.5±2.2 mmHg and 16.9±3.1 mmHg), insert, and eye drop, respectively; P=0.165). The percentage of IOP reduction in the third week was 30% for insert and 35% for eye drops (P=0.165). No intolerance or discomfort with the insert was reported. Among the research participants, 58% preferred the use of the insert while 25% preferred eye drops, and 17% reported no preference. Conclusions: Bimatoprost-loaded inserts showed similar efficacy to daily bimatoprost eye drops during three weeks of follow up, without major side effects. This might suggest a possible change in the daily therapeutic regimen for the treatment of POAG and OH.

Selective laser trabeculoplasty (SLT) is a glaucoma treatment that reduces intraocular pressure (IOP). Its mechanism is based on the biological effects of the selective application of laser energy to pigmented trabecular meshwork (TM) cells, resulting in increased outflow facility. Herein, we review current publications on SLT and summarize its efficacy and safety for different indications in open-angle glaucoma (OAG) and ocular hypertension (OHT) treatment. SLT effectively reduces IOP when used as a primary treatment. In patients whose IOP is medically controlled, SLT helps to reduce medication use, and when maximally tolerated topical therapy is ineffective, SLT facilitates the realization of the target IOP. SLT is a repeatable procedure for which the vast majority of complications are mild and self-limiting. With effective IOP reduction, low complication rates and the potential to repeat the procedure, SLT offers the possibility of delaying the introduction of medical therapy and other more invasive treatment modalities while simultaneously avoiding the accompanying complications. With this knowledge, we suggest that SLT be considered as an essential primary treatment option in OAG and OHT, switching to other treatment modalities only when laser procedures are insufficient for achieving the required target IOP.
