Treatment Of Retinal Tears Research Articles

Twelve-month analysis of emergency argon laser retinopexy in an Irish tertiary hospital.

Retinal tears occur as a result of traction at sites of retinal and vitreous adhesion-this allows retrohyaloid fluid into the subretinal space. Prompt management is required to prevent progression to rhegmatogenous retinal detachment (RRD). To identify the post-procedural outcomes following treatment of retinal tears with laser retinopexy in an emergency setting. Retrospective review of all patients who underwent emergency slit-lamp laser retinopexy between January and December 2021 in Cork University Hospital, an Irish tertiary referral centre. A total of 87 patients were identified-mean age of 60 ± 12years and 54% female. Follow-up ranged from 1week to 11months. Pre-disposing risk factors were identified-myopia (37%), recent trauma (2%), and RRD family history (5%). All patients had slit-lamp mounted laser-retinopexy performed in the eye-casualty. 63 patients (72%) had a superior break, 66 patients (76%) had a horse-shoe retinal tear, and 21 patients (24%) had a retinal hole. Associated findings included lattice degeneration (26%), sub-retinal fluid (55%), and vitreous haemorrhage (33%). Fourteen patients (16%) required multiple slit-lamp laser retinopexies while 18 patients (21%) required intervention by a vitreo-retinal surgeon including indirect-laser retinopexy (3%), cryotherapy (11%), and pars-plana vitrectomy (6%). At the most recent follow-up, all the patients had anatomically attached retinas. A notable proportion of patients (21%) undergoing emergency laser retinopexy required further intervention. Patients with anteriorly located retinal tears would benefit from an early discussion with a vitreo-retinal surgeon. Departmental training in laser retinopexy and retinal tear management is recommended as part of ongoing quality improvement.

Effectiveness of Emergency Argon Laser Retinopexy Performed by Trainee Physicians: 10 Years Later

To reassess (10 years later) outcomes after treatment of retinal tears with argon laser photocoagulation by trainee physicians as an emergency procedure. Retrospective case series analysis of 100 consecutive patients treated between September 2010 and September 2011 at a tertiary referral center, compared with the respective findings at the same institution during the period between August 2000 and December 2002. All patients underwent argon laser retinopexy in the casualty department by the on-call trainee. Forty patients (40%) needed further treatment in the form of slit lamp/indirect argon laser retinopexy or cryoretinopexy, and 58 patients (58%) received some vitreoretinal care. At final follow-up, all patients demonstrated anatomically attached retinas. The percentage needing further treatment was significantly increased compared to the relevant percentage 10 years earlier (P = .02). A significant proportion of patients required further treatment, and more than half of patients were referred to the vitreoretinal team. Over the years, trainees' indirect ophthalmoscopy and laser retinopexy skills have become progressively inadequate. Further training of junior physicians on indirect laser retinopexy may improve patient care and reduce the inconvenience of repeated visits.

Effectiveness of emergency argon laser retinopexy performed by trainee doctors.

To report the outcomes following treatment of retinal tears with argon laser photocoagulation by trainee doctors as an emergency procedure. Retrospective, case note analysis of 100 consecutive patients treated between August 2000 and December 2002 at a tertiary referral hospital. The case notes of 100 consecutive patients (41 male, 59 female) with a mean age of 57.5 years were reviewed. Out of these 90 were symptomatic. The follow-up period ranged from 1 week to 8 months. All patients had argon laser retinopexy in the Emergency department. The on-call Registrar performed the procedure on 94 patients, and Senior House Officers performed the other six. A total of 98 procedures were performed on the slit lamp and two by laser indirect ophthalmoscope. In all, 24 patients needed further treatment with either indirect laser, cryotherapy, or surgery. At the last follow-up, all the patients had anatomically attached retinas. A significant proportion of patients (24%) undergoing laser retinopexy in the emergency department needed further treatment. The relative inexperience in using the indirect laser, together with its unavailability in the Emergency department, may be the contributory factors. There seems to be scope for supervised training in using the laser indirect ophthalmoscope for the trainees in the Ophthalmic Emergency department.

Treatment of retinal tears and lattice degenerations in fellow eyes in high risk patients suffering retinal detachment: a prospective study

BACKGROUND/AIMSFellow eye prophylaxis for retinal detachment (RD) is still a controversial issue since opinions are not unanimous regarding the kind of lesions to be treated or the method of treatment....

Transforming growth factor beta. A biologic chorioretinal glue.

Transforming growth factor beta (TGF-beta) stimulates fibrosis. We studied its possible role as a bioactive substance for inducing localized chorioretinal wound healing along the edge of a retinal tear. The TGF-beta was applied to induced retinal tears that were examined histopathologically. One day after surgery, neither control nor TGF-beta-treated eyes developed chorioretinal wound healing. Four days, two weeks, and two months after surgery, the control eyes still had not developed chorioretinal wound healing. In contrast, the edges of the retinal tear treated with TGF-beta were adherent to the underlying Bruch's membrane via localized fibrous tissue without apparent effects elsewhere. These results demonstrate intraocular in vivo bioactivity of TGF-beta and suggest that TGF-beta may have a potential role as an alternative means for inducing a chorioretinal adhesion in the treatment of retinal tears.

A Transilluminating Retinal Cryoprobe

ONE OF the problems in the treatment of retinal tears by the application of cyrocongelation is the precise localization of the freezing relative to the hole. Often the freezing does not appear in the center of the mound produced by indentation of the cryoprobe. This is due to the oblique application of the tip of the probe or pressure by the probe shaft on the surface of the eye. Visualization of the probe contact area can also be a problem in cases of bullous retinal detachments. In order to overcome these problems, a transilluminated retinal cryoprobe was devised. It is constructed in such a manner that the actual point of the probe casts a circular shadow in the center of a round patch of light. Construction One thousand, clad, optical fibers (0.002 inch thick) were inserted in two hemispherical molds and embedded in epoxy resin. The distal end of the
