Unintentional injection of a dexamethasone implant into the crystalline lens: a case report
ABSTRACT The intravitreal dexamethasone implant is a sustained-release anti-inflammatory drug system that releases 0.7 mg of dexamethasone into the vitreous cavity. The following case report describes a rare complication: accidental injection of the dexamethasone implant into the crystalline lens. A 73-year-old woman was diagnosed with central retina vein occlusion and cystoid macular edema. Initial tSreatment included three monthly intravitreal doses of anti-vascular endothelial growth factor treatment, which was not successful. Treatment was then modified to an intravitreal dexamethasone implant. Ten weeks later, the imp...

Dexamethasone intravitreal implant in the crystalline lens: a case report
This report describes the therapeutic effects and outcomes of an accidental injection of an intralenticular sustained-release dexamethasone implant (Ozurdex ®) in three patients with diabetic macular edema. All three patients underwent accidental injections of sustained-release intravitreal dexamethasone implants into the crystalline lens by the same surgeon. After the accidental injection of Ozurdex® into the crystalline lens, a remarkable reduction in the macular edema and an improvement in visual acuity were observed, suggesting that a positive outcome can be achieved without immediate surgery.RESUMO Este estudo descr...

Baerveldt implant versus trabeculectomy as the first filtering surgery for uncontrolled primary congenital glaucoma: a randomized clinical trial
Conclusions: Both the tube and trabeculectomy groups presented similar intraocular pressure controls, but complete success was more frequent in the trabeculectomy grou p. Non-valved glaucoma drainage devices caused potentially blinding complications during tube opening. Because of the small sample size, we could not draw conclusions as to the safety data of the studied technique.RESUMO Objetivo: O objetivo inicial era comparar a efic ácia e a segurança do implante de drenagem e a trabeculectomia em crianças com glaucoma congênito primário após falência de cirurgia angular. Como o estudo foi descontinuado devido à ...

Costs and outcomes of phacoemulsification for cataracts performed by residents
Conclusion: These data indicate that cataract surgery performed by in-training ophthalmologists using phacoemulsification is expensive, but compared to extracapsular cataract extraction results, teaching phacoemulsification leads to an approximate three-fold lower complication rate, smaller number of postoperative visits and, most importantly, better visual acuities.RESUMO Objetivo: Descrever os custos e resultados da facoemulsifica ção na cirurgia de catarata realizada por médicos residentes de oftalmologia. Métodos: Foram obtidos prontuários médicos de pacientes operados em 2011 por residentes do terceiro ano (R3...

Infrared thermography for the analysis of ocular surface temperature after phacoemulsification
Conclusions: The reduction in ocular surface temperature toward the end of post-cataract surgery follow-up may be associated with increased instability of the tear film after phacoemulsification. Therefore, patient awareness regarding the possibility of clinical symptoms of dry eye syndrome during the first month after surgery should be part of clinical manageme nt of cataract surgery. Ocular surface temperature did not increase after cataract surgery, suggesting the absence of significant inflammation, and the temperature about 1 month after cataract surgery was comparable to that before surgery. Nevertheless, the negativ...
