Invest Ophthalmol Vis Sci. Katzen, Fleischman, and Trokel reported the use of the Nd:YAG laser to lyse strands of vitreous to cataract wounds. Participation in strenuous activities and contact sports should be restricted until recovery is complete. Whats happening is that the leak is pressure dependent and you need to challenge the eye to reveal it.. The alpha1 inhibitors bind to post-synaptic nerve endings of iris dilator smooth muscle for a prolonged period which may result in poor pupillary dilation[2][3][4]. Treatments for corneal perforations run the gamut from short-term fixes to long-term repair. Related: AI enhances customised myopic LASIK with ray tracing optimisation. As soon as the diagnosis is made, an eye shield should be applied to prevent further damage. The best way to prevent IFIS is to avoid the use of Flomax or other alpha1 inhibitors in patients who have not undergone cataract surgery. 2006 Sep-Oct;51(5):501-12. Two patients were lost to follow-up without documentation of the basis for persistent unimproved acuity. IOP elevation following vitreolysis has not been well documented. Occasionally, complete sloughing of strangulated tissue within the suture loop may occur.[3]. He reviews some of the basic mechanisms behind its etiology, including potential risk factors. Refer earlier! In these cases, the cornea can heal spontaneously, as there is minimal to no tissue loss. Diagnosis and Tests How is pelvic organ prolapse diagnosed? Pre-operative anticipation of IFIS by an experienced surgeon can dramatically decrease complication rates. It usually means that the iris had been drawn up to the area, left a mark behind indicating that some fluid had escaped there, and then fell back later, said Dr. Tu. The most common agent is Flomax, a highly selective alpha1A-receptor antagonist, but other alpha-adrenergic antagonists have been reported to be associated with IFIS([2][3][4],[5]). The following is a generalized procedural description. The precise surgical treatment varies with the circumstances. This helps to maintain a larger pupil size during surgery. Figure 1. When the cause of a perforation is trauma, Dr. Karp advises clinicians to check both eyes for additional perforations, a foreign body, or another type of injury.
