“…Die optimale Größe der LPI sollte mindestens 200 μm und vorzugsweise 500 μm im Durchmesser betragen [7]. Die Position der Iridotomie in Relation zum Oberlid sowie die Größe der Iridotomie sind wegen assoziierter Sehstörungen von Bedeutung [8]. Der AID sollte in den ersten 1-2 Stunden nach der LPI überwacht werden.…”

Fortschritte in der Bildgebung des vorderen Segments haben neue Erkenntnisse für ein besseres Verständnis der verschiedenen Mechanismen des Engwinkelglaukoms (EWG) geliefert. Diese Entwicklung ist von großer Bedeutung für eine gute Entscheidungsfindung bei Patienten mit EWG, die eine adäquate Therapie benötigen. Das chirurgische Management des EWG ist nach wie vor ein integraler Bestandteil der Patientenversorgung bei Glaukom. Die spezielle Anatomie des Auges mit Winkelverschluss und das geringe Maß an verfügbarer objektiver Evidenz für die Wirksamkeit der verschiedenen chirurgischen Behandlungsoptionen stellen Glaukomchirurgen vor Herausforderungen.

“…Dysphotopsias following iridotomy (LI) have been attributed to a base‐up prism effect caused by the tear film meniscus at the upper lid . Three notable studies compared the frequency of symptoms between an iridotomy that is covered by the upper lid, partially covered, or exposed . While only one provided definitive information about the linear dysphotopsia specifically caused by LI, we use all three studies to illustrate how to update beliefs as each study result is published.…”

“…For each study, the number of patients who experienced any visual symptoms was assumed to be generated from a binomial distribution with an unknown population probability of symptoms. In the absence of other information, an initial uniform distribution (equivalent to a beta distribution with parameters a = 1 and b = 1) was used to put equal probability for each location of LI in study 1 (Spaeth). The data from study 1 were then used to update these priors and population probabilities described by updated beta distributions based on the (initial) prior and the first set of data .…”

The management of acute primary angle closure is directed at lowering the intraocular pressure and relieving pupil block. Conventional treatment involves the use of medical treatment and laser peripheral iridotomy, respectively, as a means for achieving these aims. Newer therapeutic strategies have been described that are potentially useful adjuncts or alternatives to conventional treatment. Emerging strategies that lower intraocular pressure include anterior chamber paracentesis, as well as laser procedures such as iridoplasty and pupilloplasty. A possible alternative to relieving pupil block is lens extraction, and may be combined with adjunctive measures such as goniosynechiolysis and viscogoniosynechiolysis. Trabeculectomy has a limited role in the acute setting. This review paper reviews the current evidence regarding conventional and newer treatment modalities for acute primary angle closure.

The Effects of Iridotomy Size and Position on Symptoms Following Laser Peripheral Iridotomy

Abstract: Visual symptoms following laser peripheral iridotomy are more likely to occur in patients who have partially or fully exposed laser iridotomies than in those in whom the iridotomy is completely covered by the lid.
