“…This method is used for premacular subhyaloid haemorrhages owing to Valsalva retinopathy, proliferative diabetic retinopathy, retinal artery macroaneurysm, branch retinal vein occlusion, Terson syndrome, and blood dyscrasias. [12][13][14][15][16][17][18][19][20][21] The power setting of the Nd:YAG laser systems used varied between 2, 1, and 50 mJ. 13,16 Visual acuity improved within days in most of the patients after treatment and no laser related complications were seen during the follow-up period of 6 months.…”

“…[12][13][14][15][16][17][18][19][20] Eyes with Valsalva retinopathy fared the best among the other etiologic factors owing to lack of any underlying retinal pathology. 21 Most of the patients with Valsalva retinopathy are young and otherwise healthy and are seeking a rapid visual restoration in order to be able to continue working.…”

Aims Valsalva retinopathy produces sudden visual loss, which may be prolonged if untreated. Nd:YAG laser enables rapid diffusion of premacular subhyaloid haemorrhage. This study was performed to assess the long-term results and safety of Nd:YAG laser treatment in cases with Valsalva retinopathy. Methods Sixteen patients had Nd:YAG laser treatment to drain premacular haemorrhage. The follow-up period was 24 months. Results All eyes had marked clearing of haemorrhage and immediate improvement of vision following laser treatment. In 14 eyes visual acuity improved to 20/20 level at the end of the first week and the remaining two patients achieved 20/20 level within 1 month. No patient had evidence of retinal or choroidal damage. Conclusion Nd:YAG laser treatment for Valsalva retinopathy is an effective, noninvasive, and safe procedure for patients with a premacular subhyaloid haemorrhage larger than 3 disc diameter and no longer than 3 weeks of duration.

“…Gegenuber der veroffentlichten Literatur ist die diabetische Retinopathie als Ursache einer pramakularen Blutung in unserer Serie unterproportional vertreten [4,7,9,14,20,21]. Dies ist darauf zuruckzufuhren, dalI Patienten mit einer schweren proliferativen Retinopathie mit rezidivierenden Glaskorperblutungen and beginnenden Glaskorpertraktion aufgrund der Prognose der Erkrankung eher eine Indikation fur eine rasche komplette panretinale Photokoagulation and/oder Pars-Plana Vitrektomie als fur eine fokale YAGMembranotomie darstellte.…”

Zusammenfassung. Pramakulare Sublimitansblutungen konnen in vielen Fallen eine akute Sehverschlechterung verursachen. Kleine Blutungen resorbieren ausreichend rasch. Grof3ere Hamorrhagien zeigen eine verzogerte Resorption and konnen zu einer dauerhaften Visusbeeintrachtigung fuhren. Wir haben den therapeutischen Effekt and die Sicherheit der Nd : YAG-Membranotomie untersucht.Es wurden die Krankengeschichten jener Patienten analysiert, bei denen in den letzten 5 Jahren eine pramakulare Hamorrhagie aufgetreten war. In 10 Fallen wurde eine Perforation der Membrana limitans intema mit dem Q-switched Nd : AG Laser (Zeiss) durchgefuhrt. Bei 5 Patienten wurde ein naturlicher Verlauf beobachtet.In 6 Fallen war die Sublimitansblutung nach einem Valsalva-Manover aufgetreten. Ebensoviele Patienten hatten ein arterielles Makroaneurysma. Bei 3 Individuen lag eine diabetische Retinopathie vor. Durch die Membranotomie kam es bei alien zu einer raschen Verlagerung des Blutes in den retro-oder intravitrealen Raum. In der Therapiegruppe war schon nach einer Woche ein rund 4,7fach hoherer Visusanstieg (3,98 Zeilen auf 0,49 ± 0,40) als in der Kontrollgruppe (0,84 Zeilen auf 0,31 ± 0,40) festzustellen. Nach Ende der Beobachtungszeit lag der mittlere Fernvisus in der Behandlungsgruppe bei 0,93 ± 0,20 (Anstieg um 8,32 Zeilen) and bei 0,88 ± 0,38 (Anstieg um 6,56 Zeilen) in der unbehandelten Gruppe. Bei einem Patienten mit einer kleinen, flachen Blutung kam es durch die Behandlung zu einer lokalen Aderhautblutung. Aufgrund des fur die Netzhaut bestehenden Risikos ist die Nd : YAG Laserbehandlung nur bei hinreichend dicken Sublimitansblutungen indiziert, bei denen einer raschen Spontanresorption nicht gerechnet werden kann.Schlusselworter: Pramakulare Blutung, Membrana limitans interna, Neodymium : YAG Laser, Membranotomie, Sehscharfe. Neodym:YAG membranotomy of premacular hemorrhages under the internal limiting membraneSummary. Acute premacular hemorrhages may severely decrease visual acuity. Small hemorrhages resolve in a reasonable time but sometimes large hematomas cause an irreversible vision loss. Our major objective was to investigate the therapeutic effect of Neodymium : YAG membranotomy and whether we can state this method as a safe one. We analysed all patient records of the last five years where a subinternal limiting membrane hemorrhage occurred. 10 cases were treated with laser and in 5 patients we observed the natural course.In 6 cases preretinal hemorrhage was caused by valsalva retinopathy and the same number of cases had an arterial macroaneurysm. 3 individuals had some stage of diabetic retinopathy. With the membranotomy we forced a fast relocation of the hemorrhage into the retro-or intravitreal space. One week after the event we found in the treatment group a 4.7-fold improvement of Snellen visual acuity (nearly 4 lines to 0.49 ± 0.40) versus the control group where Snellen visual acuity increased only 0.84 lines to 0.31 ± 0.40. At the end of follow-up period the mean visual acuity in the treatment group was 0.93 ± 0....

To investigate the effects of drainage of premacular subhyaloid hemorrhage into the vitreous with an Nd:YAG laser in a large series of patients with longterm follow-up. Methods: A retrospective review was conducted on 21 eyes with a circumscribed premacular subhyaloid hemorrhage of various causes. These eyes were treated with a pulsed Nd:YAG laser to drain the entrapped blood into the vitreous. The period of review ranged from 12 to 32 months (mean, 22 months). Results: In 16 eyes, visual acuity improved within 1 month. Four eyes had persistent, dense, nonclearing vitreous opacity for at least 3 months and finally required vitrectomy. One clotted hemorrhage did not drain into the vitreous. Final visual outcome was determined by the underlying diagnosis, such as Valsalva retinopathy (7
