LARA-MEDINA, J. et al. Peripheral vitreoretinal traction exploration by Staurenghi 230 lens and HRA-II. Arch Soc Esp Oftalmol [online]. 2009, vol.84, n.12, pp.625-629. ISSN 0365-6691.

Purpose: To report a new technique to explore peripheral vitreous-retinal tractions in patients with acute posterior vitreous detachment. Material and methods: A population of 65 patients with acute posterior vitreous detachment was studied by panfunduscopic SLO 230 lens and HRA-II to detect peripheral retinal tears and vitreous-retinal tractions. Results: In our study, using indirect ophthalmoscopic exploration, we identified eleven patients with at least one retinal tear. HRA-II combined with the Staurenghi SLO 230 lens was capable of detecting 100% of these lesions. In addition, by means of this technology, we identified dark retinal zones that corresponded to peripheral retinal traction in six patients. None of the 65 patients complained of pain or photophobia during the exploration with this contact lens. Retinal tears and peripheral vitreous-retinal traction were treated by argon laser photocoagulation to create a firm chorioretinal adhesion. In two patients we found new retinal tears in the follow-up, with these new lesions detected by indirect ophthalmoscopy and HRA-II with SLO 230 lens. Conclusion: HRA-II with the panfunduscopic Staurenghi SLO 230 lens can complement the exploration of patients with acute posterior vitreous detachment and can help to detect tractional zones that could develop into retinal tears.
