Reliability of Intraocular Pressure by Tono-Pen XL over Amniotic Membrane Patch in Human

Abstract Background The basis of retinal detachment repair is sealing the retinal breaks. In order to seal the retinal breaks, chorioretinal adhesion around these lesions has to be achieved. Laser retinopexy is not immediate thus necessitates the use of a temporal endotamponade to maintain both tissues in apposition. We propose the use of a patch of lyophilized human amniotic membrane (LAMPatch) in order to occlude the retinal tear effectively until the chorioretinal adhesion is settled, overcoming the risks and limitations of the current tamponades. Methods 23-gauge vitrectomy was performed on eyes with primary retinal detachment with single retinal breaks of less than one-hour extension. A LAMPatch was deployed over the retinal breaks after retina was repositioned with perfluorocarbon. Neither gas nor silicon oil were injected. Results Six eyes of six patients with total or partial retinal detachment were included. Retinas remained reattached in all cases until the end on follow-up (3, 5 months). Best-corrected visual acuity at 1-week postop was between 20/30 and 20/100. Neither elevations of intraocular pressure, cataracts nor signs of inflammation were registered during follow-up. No second surgeries were needed. Conclusion This technique has proven to be safe and effective in this small case series. No intraocular pressure rise, inflammation or cataracts were registered until last follow-up visit.

Introduction We described a case of initial unsuccessful outcome of failed macular hole treated with amniotic membrane, that resolved after amniotic membrane exchange and silicone oil injection. Case Description a woman affected by a high myopic macular hole that had failed to close after multiple surgeries, had been treated using an amniotic membrane graft and 20% sulfur hexafluoride but, after the gas reabsorption, the macular hole was still open, and the amniotic membrane. A second surgery with a second amniotic membrane patch and silicone oil was carried out. Two weeks after the procedure the macular hole closed, and the final visual acuity improved from 20/400 to 20/100. Conclusions In this case, a second surgery, using a new amniotic membrane graft and a longer-lasting endotamponade, closed the hole and improved the visual acuity.
