Introduction: The survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. Implant success also is affected by the maintenance of the crestal bone around implants. The aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...

This article describes how to give an intravitreal injection of an anti-VEGF drug. At present, the majority of intravitreal injections are administered by doctors; however, experience in the UK has shown that trained nurses can give these injections as safely as ophthalmologists. The single most important thing to remember is that an intravitreal injection is an intraocular operation, and shoul...

BACKGROUND The purpose of this study was to evaluate the safety of intravitreal ranibizumab injection in patients with age-related macular degeneration. MATERIALS AND METHODS We examined retinal ganglion cell function using the photopic negative response of the electroretinogram (ERG) in patients with age-related macular degeneration (AMD) treated with intravitreal injections of ranibizumab. ...

background: decalcified freeze-dried bone allograft (dfdba) may have the potential to enhance bone formation around dental implants. our aim in this study was the evaluation and comparison of two types of dfdba in treatment of dehiscence defects around euroteknika ® implants in dogs.     methods: in this prospective clinical trial animal study, all mandibular premolars of three iranian dogs wer...

Steroids in susceptible individuals can cause a clinical condition similar to primary open-angle glaucoma. Five percent of the population are high steroid responders and develop an intraocular pressure (IOP) elevation of more than 15 mm Hg above baseline. IOP elevation may occur as early as 1 day to as late as 12 weeks after intravitreal triamcinolone in 20–65% of patients. On average, 75% of e...

BACKGROUND Dexamethasone intravitreal implant (DEX implant) is a biodegradable, sustained-release implant that releases dexamethasone for up to 6 months. We evaluated the efficacy and safety of DEX implant in the treatment of macular edema secondary to retinal vein occlusion (RVO) in treatment-naïve patients. METHODS A multicenter, retrospective, open-label chart review study investigated the...

BACKGROUND Dexamethasone intravitreal implant (DEX implant) is a sustained-release biodegradable implant approved for treatment of macular edema associated with retinal vein occlusion (RVO). The safety and efficacy of treatment of RVO-associated macular edema with sequential DEX implants in clinical practice was evaluated in patients who received DEX implant as monotherapy compared with patient...

BACKGROUND Cytomegalovirus (CMV) retinitis is an opportunistic infection that primarily affects immunocompromised individuals. Intravitreal ganciclovir injection monotherapy or in combination with systemic anti-CMV therapy are effective treatments for CMV retinitis. Crystallization of ganciclovir after intravitreal injection is extremely rare. Only two cases had been reported in literature. Cry...
