Two hundred sixty eyes of 195 patients having extracapsular cataract extraction (ECCE) with insertion of a posterior chamber intraocular lens were studied retrospectively. Of these cases, 160 eyes had preexisting glaucoma while 100 had no ocular pathology except for cataract. Intraocular pressure decreased significantly after ECCE in both groups and slowly(More)
This study evaluated and compared the corrosion susceptibility of stainless-steel and nickel-titanium (NiTi) endodontic files immersed in sodium hypochlorite. For each of the stainless-steel files (Kerr K-Flex, Caulk Flex-O, and Union Broach Flex-R) plus the NiTi files (Union Broach NiTi and Tulsa NiTi), the cutting flutes of 24 ISO size 20 files were(More)
This paper examines the effects of intraocular epinephrine on systemic blood pressure and heart rate during cataract surgery. Sixty-two patients were studied, all of whom received an intraocular infusion of approximately 200 to 300 mL of balanced salt solution with 0.5 mL of epinephrine 1:1000. There was no statistically significant change in blood pressure(More)
A patient with refractory glaucoma secondary to trauma and repeat penetrating keratoplasty had Molteno implant surgery to control elevated intraocular pressure. Six weeks after surgery intraocular pressure rose abruptly, and a fibrinous membrane was seen covering and occluding the tip of the Molteno tube. The Q-switched neodymium (Nd):YAG laser was used(More)
The authors present four cases of the dural shunt syndrome in which shallowing of the anterior chamber or rubeosis developed. All patients were female, ranging in age from 66 to 79 years, exhibiting elevated intraocular pressure (IOP), decreased extraocular movements, injected tortuous episcleral vessels, and proptosis. The authors managed these four cases(More)
Fifteen years after orbital floor fracture repair with a silicone implant, dacryocystitis unresponsive to medical management developed in a 66-year-old woman. On examination, the edge of the implant was palpable at the most medial aspect of the inferior orbital rim in the anatomic area of the nasolacrimal sac. Orbital computed tomography (CT) scan and(More)
In recent years aqueous drainage implants have become a useful adjuvant in the treatment of refractory glaucomas. The Molteno implant is one of the most widely used devices for providing a permanent channel of aqueous flow from the anterior chamber to a collecting reservoir in the posterior subconjunctival space. Recently, modifications in design and(More)
