The immortal Ologen: persisting 10 years after trabeculectomy
The surgical management of glaucoma has been evolving over the past few decades. In an attempt to improve the results of trabeculectomy, a number of modifications have been tried, of which Ologen (Aeon Astron, Leiden, The Netherlands) is one adjunct.1,2 Ologen is being extensively used for filtering surgeries and is known to undergo complete biodegradation within 90–180 days of implantation.3 We report a case of trabeculectomy failure in both eyes (BE) of a patient who had undergone augmented trabeculectomy with Ologen, which was seen to be retained for 10 years postsurgery.Bilateral neovascular glaucoma in idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome
The association of bilateral retinal macroaneurysms with retinal vasculitis and neuroretinitis was first described by Kincaid and Schatz.1 The condition later was renamed as idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN).2 The retinal vasculitis may result in capillary occlusion and capillary nonperfusion. This causes retinal ischemia, leading to release of vascular endothelial growth factors, and subsequently results in anterior segment neovascularization causing neovascular glaucoma (NVG).Iris spatula-guided epinuclear cleavage in posterior polar cataracts
Posterior polar cataracts pose a challenge to every cataract surgeon even today in the era of advanced phacoemulsification and improved instrumentation. They are transmitted as an autosomal dominant trait and represent a weak or pre-existing dehiscent posterior capsule leading to complications during phacoemulsification. They classically are described as having a “rosette or ring onion” posterior capsular opacity.1 Pre-existing capsular dehiscence can sometimes be appreciated as having a “fish tail sign” in anterior vitreous or an oval defect in the posterior capsule on retro illumination.Posterior lens capsular neovascularization of young: management using endodiathermy assisted biopsy
Neovascularization of lens capsule has so far been described in cases of retinal detachment or proliferative diabetic retinopathy in pseudophakes.1–4 We hereby describe a unique case that presented with posterior lens capsular neovascularization in the absence of any other sign of anterior segment neovascularization, and it was found to be associated with idiopathic ciliary body inflammation. The management with regard to clearing of the visual axis, biopsy of the involved tissue, and follow-up is described.Corneal nerve regeneration after foreign body removal on in vivo confocal microscopy
The purpose of this article was to report confocal microscopy findings in a case of ocular siderosis. A 23-year-old male presented 1 year after projectile injury with an iron particle from hammer and chisel, with ocular siderosis and a retained intracorneal foreign body. Corneal confocal microscopy was done to document features of ocular siderosis at baseline; subsequent localization of foreign body with anterior segment optical coherence tomography (ASOCT) and surgical removal was done. A follow-up confocal microscopy was done at 3 months thereafter.
