A retrospective review of selective laser trabeculoplasty outcomes at Lancashire Teaching Hospitals, UK
Selective laser trabeculoplasty has been carried out at Lancashire Teaching Hospitals over the past seven years. This work aimed to review the use of SLT in this Trust. The primary objectives were to establish the efficacy of SLT in reducing intraocular pressure, to analyse how prior treatment with different topical medications can influence SLT outcomes and to analyse the outcomes in revisionary patients. We conducted a retrospective review of 288 eyes, with a known history of glaucoma or ocular hypertension and who underwent initial SLT laser treatment between October 2018 and January 2020. SLT was performed on known glaucoma and treatment naïve patients where IOP control was deemed sub-optimal. All patient data was fully anonymised. We found that SLT was effective in lowering IOP. Around two-thirds of the eyes (181/280, 65%) achieved a reduction in IOP of 10% or more. Just under half (127/280, 45%) achieved a reduction of 20% or more. For a pre-SLT IOP of 14.6 mmHg, we found that no mean change in IOP is expected, and for each 1 mmHg by which the pre-SLT IOP exceeds this threshold, the mean reduction in IOP is expected to be 0.61 mmHg. We also found that combination therapies of PGA plus aqueous suppressants gave better outcomes compared with PGA alone. We found that revisionary SLT compared favourably with the first treatment, although first-time outcomes were not a good predictor of success with revisionary SLT. Primary and revisionary SLT has been shown to be effective across the cohort of patients in this study.
期刊介绍:
Eye seeks to provide the international practising ophthalmologist with high quality articles, of academic rigour, on the latest global clinical and laboratory based research. Its core aim is to advance the science and practice of ophthalmology with the latest clinical- and scientific-based research. Whilst principally aimed at the practising clinician, the journal contains material of interest to a wider readership including optometrists, orthoptists, other health care professionals and research workers in all aspects of the field of visual science worldwide. Eye is the official journal of The Royal College of Ophthalmologists.
Eye encourages the submission of original articles covering all aspects of ophthalmology including: external eye disease; oculo-plastic surgery; orbital and lacrimal disease; ocular surface and corneal disorders; paediatric ophthalmology and strabismus; glaucoma; medical and surgical retina; neuro-ophthalmology; cataract and refractive surgery; ocular oncology; ophthalmic pathology; ophthalmic genetics.
