Clinical Outcomes of Ahmed ClearPath Implantation in Glaucomatous Eyes: A Novel Valveless Glaucoma Drainage Device.

PRCIS: Designed with novel features to facilitate implantation and improve safety, the Ahmed ClearPath (ACP) glaucoma drainage device (GDD) provided intraocular pressure (IOP) reduction comparable with other GDDs in eyes with refractory glaucoma in a multicenter retrospective study. PURPOSE: To present clinical outcomes with a novel valveless GDD (ACP, New World Medical). The 250 and 350 mm2 models feature a contoured plate for optimal globe apposition, anteriorized suture points to facilitate suturing to the globe, and a prethreaded 4-0 polypropylene ripcord suture. METHODS: This was a multicenter retrospective analysis of eyes with medically and/or surgically uncontrolled glaucoma implanted with the 250 or 350 mm2 ACP either as a standalone procedure or in combination with other procedures. Pre-, intra-, and postoperative data through 6 months were collected. RESULTS: A total of 104 eyes (100 subjects) received the ACP by 10 US surgeons, 63.5% of which had primary open-angle glaucoma and 62.5% had severe glaucoma. Mean baseline IOP was 26.3 (9.0) mm Hg and mean medication use was 3.9 (1.3). Through 6 months' follow-up, mean IOP ranged from 13.6 to 16.7 mm Hg and mean medication use from 0.9 to 1.9 medications (P<0.0001 at all timepoints for each outcome measure). At 6 months, mean IOP was 13.7 mm Hg (-13.0 mm Hg, 43.0%, P<0.0001) and mean medication use was 1.9 medications per eye (-2.1, 47.7%, P<0.0001). Common adverse events included anterior chamber inflammation (16.3%), hyphema (15.4%), and hypotony (6.7%). CONCLUSION: The new ACP appears to be safe and efficacious as a standalone procedure or in combination with other procedures for uncontrolled glaucoma, and may be considered as a GDD option for patients in whom its unique design may facilitate the implantation process.

Combination anti-VEGF and corticosteroid therapy for idiopathic retinal vasculitis, aneurysms, and neuroretinitis syndrome.

Vision loss associated with the idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome most commonly occurs from macular edema or complications related to neovascularization. The authors present a case of advanced IRVAN associated with a massive exudative response characterized by peripheral retinal telangiectasias, exudative retinal detachment, and macular edema with lipid maculopathy. The patient was managed successfully with visual acuity from hand motion to 20/150 using a combination of local corticosteroids, intravitreal bevacizumab, panretinal photocoagulation, and eventually pars plana vitrectomy for progressive vitreomacular traction. VEGF- and non-VEGF-mediated mechanisms appear to be involved in the pathogenesis of IRVAN given the efficacy of combination therapy. [ophthalmic surg lasers imaging retina. 2013;44:599-602.].

An aggressive sphenoid wing meningioma causing foster kennedy syndrome.

Foster Kennedy syndrome is a rare neurological condition with ophthalmic significance that can manifest as acute visual loss. It is classically characterised by unilateral optic nerve atrophy and contralateral papilledema resulting from an intracranial neoplasm. Physicians should consider Foster Kennedy syndrome in patients who present with visual loss and who have a history of intracranial neoplasm. In addition to ophthalmologic examination, neuroimaging is essential for the diagnosis of Foster Kennedy syndrome.

The value of serial personal photographs in timing the onset of unilateral cataracts in children.

PURPOSE: To determine the value of serial personal photographs in timing the onset of unilateral cataracts in children over 6 months of age. METHODS: Personal photographs from children with unilateral cataracts who underwent cataract extraction and intraocular lens implantation when > or =6 months of age were reviewed. Photographs were evaluated for changes in the red reflex, which might indicate the presence of a cataract. RESULTS: Twelve children underwent cataract surgery at a mean age of 37 months. They were followed for a mean of 32 months. Ten children were diagnosed as having an acquired cataract by photographic review documenting a previously normal red reflex. The visual acuity in the affected eye of 4 of these children improved to > or =20/60. Cataracts were visible on photographs prior to clinical diagnosis in 6 patients, from 0.5 to 22 months prior to clinical diagnosis. Visual outcomes did not relate closely to the photographically documented duration of the cataract prior to treatment. Photographs were not helpful in timing the onset of cataract in 2 children due to the poor quality of the images. CONCLUSIONS: Serial personal photographs are sometimes helpful in determining whether cataracts are acquired. However, the usefulness of personal photographs alone in predicting the visual outcome after cataract surgery was limited in this small, retrospective study.
