Scleral punch method with topical mitomycin C for safe revision of failed deep sclerectomy in nanophthalmic uveal effusion syndrome.

PURPOSE: To describe a novel surgical technique for revision of deep sclerectomy surgery in nanophthalmic uveal effusion syndrome. METHODS: A 46-year-old woman with recessively inherited nanophthalmos and chronic uveal effusions underwent a revision of previous failed deep sclerectomy surgery. In the presence of scar tissue, revision of sclerectomies was greatly facilitated by the use of a Kelly scleral punch (Katena Products, Inc., Denville, NJ, USA). To inhibit further scarring, mitomycin-C (MMC) was applied topically in each quadrant posterior to the equator. RESULTS: The scleral punch allowed outward scleral dissection from the suprachoroidal space, and brisk enlargement of sclerectomies in all quadrants without perforation of choroidal tissue. Post-operative conjunctival wound healing appeared unimpeded by the posteriorly placed MMC sponges. Near-total resolution of the effusions had occurred by 3 months. CONCLUSIONS: The scleral punch provides a safe and effective method for constructing and revising full-thickness sclerectomies in the nanophthalmic eye, minimizing the risk of choroidal trauma. The use of topical MMC may reduce the risk of late failure of trans-scleral outflow due to fibrosis

Combined phacoemulsification and removal of gas following macular hole surgery.

We describe a technique for combined fluid-gas exchange and phacoemulsification 2 weeks after macular hole surgery to achieve rapid visual rehabilitation. The procedure uses a standard cataract set and requires minimal vitreoretinal expertise. We encountered no significant complications and obtained long-term outcomes comparable to those with conventional management

Zoonotic helminths affecting the human eye

<p>Abstract</p> <p>Nowaday, zoonoses are an important cause of human parasitic diseases worldwide and a major threat to the socio-economic development, mainly in developing countries. Importantly, zoonotic helminths that affect human eyes (HIE) may cause blindness with severe socio-economic consequences to human communities. These infections include nematodes, cestodes and trematodes, which may be transmitted by vectors (dirofilariasis, onchocerciasis, thelaziasis), food consumption (sparganosis, trichinellosis) and those acquired indirectly from the environment (ascariasis, echinococcosis, fascioliasis). Adult and/or larval stages of HIE may localize into human ocular tissues externally (i.e., lachrymal glands, eyelids, conjunctival sacs) or into the ocular globe (i.e., intravitreous retina, anterior and or posterior chamber) causing symptoms due to the parasitic localization in the eyes or to the immune reaction they elicit in the host. Unfortunately, data on HIE are scant and mostly limited to case reports from different countries. The biology and epidemiology of the most frequently reported HIE are discussed as well as clinical description of the diseases, diagnostic considerations and video clips on their presentation and surgical treatment.</p> <p><b><it>Homines amplius oculis, quam auribus credunt</it></b></p> <p><b>Seneca Ep 6,5</b></p> <p><b>Men believe their eyes more than their ears</b></p
