“…Despite its intralenticular location, the implant may still improve or resolve macular edema, as intended [ 1 , 7 , 8 , 9 ] and as was seen in our patient. The achievement of therapeutic vitreous concentration levels despite complete sequestration within the lens is also unknown.…”

“…The achievement of therapeutic vitreous concentration levels despite complete sequestration within the lens is also unknown. The implant may be partially intralenticular and partially intravitreal; in these cases, macular edema has been observed to remain resolved for up to 8 months following injection [ 9 , 10 ].…”

“…It is delivered via a prepackaged 22-gauge injection device. The literature reveals previous cases of inadvertent intralenticular administration of Ozurdex [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. We report the case of a 60-year-old woman who was found to have an Ozurdex implant in the crystalline lens of the left eye in the setting of previously treated proliferative diabetic retinopathy with refractory diabetic macular edema (DME).…”
Reported here is a case of intralenticular sustained-release dexamethasone implant (Ozurdex®, Allergan, Irvine, CA, USA) present for 1 year with effective treatment of refractory diabetic macular edema without rapid cataract formation. The crystalline lens remained stable for 12 months on exam despite the presence of the steroid-secreting foreign body. The diabetic macular edema resolved on exam and on optical coherence tomography. After 1 year, cataract extraction was uneventfully performed by phacoemulsification for a mild decline in visual acuity. Macular edema remains resolved 2 months following cataract removal. This is the longest reported period of observation of intralenticular Ozurdex in the literature. Ozurdex remains effective despite intralenticular location, and it can have minimal effects on cataract progression.

“…No new safety concerns were identified with ranibizumab or dexamethasone intravitreal implant treatment in this study (Abdolrahimzadeh et al. ). Overall, the incidences of ocular and non‐ocular AEs were higher with dexamethasone than with ranibizumab treatment.…”
Ranibizumab PRN resulted in greater visual acuity (VA) gains in macular oedema following BRVO compared with single-dose dexamethasone over a 6-month study period, observed from month 3, when administered according to their European label. In clinical practice, retreatment with dexamethasone may be required prior to this point.
“… 22 Furthermore, with the advent of intravitreal injections and steroid implants in various pathologies, it is a useful tool to evaluate complications such as injection or migration of implants in the anterior segment. 23 – 25 …”
Ultrasound biomicroscopy is a non-invasive imaging technique, which allows high-resolution evaluation of the anatomical features of the anterior segment of the eye regardless of optical media transparency. This technique provides diagnostically significant information in vivo for the cornea, anterior chamber, chamber angle, iris, posterior chamber, zonules, ciliary body, and lens, and is of great value in assessment of the mechanisms of glaucoma onset. The purpose of this paper is to review the use of ultrasound biomicroscopy in the diagnosis and management of rare diseases of the anterior segment such as mesodermal dysgenesis of the neural crest, iridocorneal endothelial syndrome, phakomatoses, and metabolic disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
