Aim: To check the short-term tonometric results of SLT in the treatment of primary glaucoma at the open angle and in charge of ocular hypertonias in Togolese people. Methods: A retrospective study was carried out in an ophthalmology center. The first 130 eyes of 72 patients benefited from the SLT laser procedure. The tonometric controls work object focus on follow-up at 1, 3, and 6 months post laser treatment. Results: 130 eyes of 72 patients were collected. The average age of the patients was 49.74 years (± 17.45) and the ages vary between 10 and 85 years. The average IOP of the laser before the laser (J0) was (24.99 ± 8.41) mm Hg. The mean IOP at the post-laser control at 1 month was (18.79 ± 3.73) mm Hg. The average IOP for the post-laser control at 3 months was (18.44 ± 3.81) mm Hg. The mean IOP at the post-laser control at 6 months was (18.13 ± 3.63) mm Hg. The percentage reduction in intraocular pressure compared to IOP was pretreated from 20.2% to 1 month; 22.1% at 3 months; and 23.3% at 6 months. In 1 month, 49.2% of the eyes we treated showed a reduction in IOP of less than 20% compared to IOP pretreatment. After 3 months and 6 months, it was 55.4% higher. Also, 52.3% have a PIO reduction percentage which is greater than or equal to 20% compared to pre-treatment IOP. Discussion: Selective laser trabeculoplasty, most especially, is interesting in ocular hypertonies. Treatment of over 180 ° allows one patient out of two to have a pressure reduction that is greater than or equal to 20%. Conclusion: The SLT presents a significant advantage for our glaucomatous patients.

BACKGROUND: Glaucoma remains one of the current problems of modern ophthalmology. The combination of glaucoma and cataract is observed in 1738.6% of cases, and glaucoma with pseudoexfoliative syndrome in 2050% of primary open-angle glaucoma cases. AIM: The aim of this work is to develop an effective and safe technology of complex energetic surgical treatment of the incipient primary open-angle glaucoma stage and cataract on the background of pseudoexfoliation syndrome on the basis of modified laser, hydrodynamic and ultrasound methods use. MATERIALS AND METHODS: 187 patients (187 eyes) with the incipient stage of primary open-angle glaucoma, cataract and pseudoexfoliation syndrome were examined. In the main group (111 eyes), selective laser trabeculoplasty followed by femtosecond laser-assisted cataract surgery with hydrodynamic trabeculocleaning was performed. Patients in the control group (76 eyes), after selective laser trabeculoplasty, underwent phacoemulsification according to the standard technique. RESULTS: The developed technology allowed to reach the hypotensive effect in 35.2% (t=23.0; р 0.001) of baseline intraocular pressure values, of individual intraocular pressure level without adding IOP-lowering medications in 27% of cases, stabilization of visual functions and morphometric indices of the optic disc during 2 years of follow-up in 97.3% of cases unlike the selective laser trabeculoplasty with subsequent phacoemulsification (21.2, 5.3 and 81.6% respectively). The patients of the main group had significantly lower energy expenditure during the stage of phacoemulsification, a lower percentage of postoperative inflammatory reaction was noted, and a persistent hypotensive effect with stabilization of visual functions was achieved based on the results of a two-year follow-up. CONCLUSIONS: Femtosecond laser-assisted phacoemulsification, performed as part of complex treatment in patients with cataract and incipient stage of primary open-angle glaucoma, is a sparing method that minimizes surgical trauma and achieves a persistent hypotensive effect, reduces intraocular pressure to an individual level and stabilizes visual functions in 97.3% of cases.

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.

AimsTo compare the intraocular pressure (IOP) lowering effect and safety profile between pattern scanning laser trabeculoplasty (PSLT) and selective laser trabeculoplasty (SLT) in patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT) over a 12-month follow-up.Methods132 patients with POAG or OHT were consecutively enrolled and randomised (1:1) to receive PSLT (n=65) or SLT (n=67) in a single centre. IOP was measured before and then on 1 day, 1 week, 1, 3, 6, 9 and 12 months after PSLT/SLT. The primary outcome measure was the proportion of patients with ≥20% IOP reduction at 12 months without IOP-lowering medications (complete success).ResultsThe mean baseline IOP was 21.2±4.1 mm Hg for eyes randomised to PSLT and 21.3±4.7 mm Hg for eyes randomised to SLT (p=0.898). At 12 months, the IOP was 18.3±3.1 and 17.8±3.4 mm Hg, respectively (p=0.402). IOP measurements were comparable between the groups over 12 months (overall mean difference 0.4 mm Hg, 95% CI: −0.5 to 1.3 mm Hg). 15.4% of PSLT-treated and 25.4% of SLT-treated patients achieved treatment success (difference: 10.0%, 95% CI: −3.6 to 23.6) (p=0.155), respectively. A higher baseline IOP and a greater percentage of IOP reduction at day 1 were associated with a greater percentage of IOP reduction at 12 months (p<0.001). There were no significant differences in visual field mean deviation, average retinal nerve fibre layer thickness, corneal endothelial cell count and visual acuity between the treatment groups at the baseline and 12-month follow-up (p≥0.062).ConclusionsPSLT was not superior to SLT in terms of safety and IOP-lowering efficacy in patients with POAG or OHT.Trial registration numberThe clinical trial was registered in the Centre for Research and Biostatistics Clinical Trials Registry, the Chinese University of Hong Kong (Identifier CUHK_CCT00407).

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.
