Beneficial of Direct-view for Submacular Surgery
Ma Zhizhong (1)
1. Peking University Eye Center, Peking University Third Hospital
Beneficial of direct-view submacular surgery is introduced. Temporal half-circle
peripheral retinotomy is performed and flipped toward the nasal side to create
direct-view surgical field for submacular manipulations. The technique is
aiming to maximal preservation of retinal pigment epithelium, precise removal
of choroidal neovessel, and tissues transplantation with avoiding injury
of Bruch›s membrane and macular. Better specimen could be obtained for
histopathological analysis. Other utilities such as delivery of pharmaceutical
agents, transplantation of cultured tissues, mounting of visual prothesis are
perspective.

The Regulatory Effect of Notch Signaling in Ocular Angiogenesis.
Yusheng Wang (1)
1. Department of Ophthalmology, Xijing Hospital
Ocular angiogenesis is characterized by the formation of neo-vessels in the
eye. This process is orchestrated by interactions between vascular cells and
multiple signals. To date, while VEGF is identified as the most critical angiogenic
agent with remarkable therapeutic potential, Notch signaling appears to be
another important regulator. Recent progress highlights the involvement of
Notch signaling in retinal vasculature development and ocular pathological
angiogenesis, and offers the possibility of modulation on Notch signaling in the
treatment of pathological ocular angiogenesis.

Topical Therapy of Conjunctival Neoplasm
Hintschich Christoph (1)
1. Department of Ophthalmology, Ludwig-Maximilians-University Munich
Conjunctival neoplasias are a heterogeneous entity of conjunctival lesions,
including pigmented and non-pigmented epithelial lesions of different
malignancy. The management is based on the histopathologic diagnosis, the
therapy often combines different approaches, like surgery, cryo and topical
chemotherapy. Up to now, no effective standard therapy without side effects has
been established. Most commonly used substances are anti-metabolites like
5-Fluoruracil and Mitomycin C, both being effective, however, with significant
side-effects. More recently, Interferon alpha-2b (1 Mio IU/ml IntronA® 5 drops/
day for 6 weeks) showed promising results in conjunctival neoplasia.

Sebaceous Gland Carcinoma of the Eyelid - The Silent Killer
Mukherjee Bipasha (1)
1. Medical Research Foundation
Sebaceous gland carcinomas (SGC) have been conventionally described as a
rare lid tumor (less than 1%) in Western literature. However, studies from
various parts of Asia have proved SGC to be one of the commonest malignant
lid tumors. It is imperative to recognize and treat this aggressive lesion without
delay because of its propensity for extensive local involvement frequently
necessitating exenteration and distant metastasis with 30% mortality rate
reported in the literature.

New trends for Lacrimal Gland Tumors Treatment
Strianese Diego (1)
1. University of Naples ‹Federico II›
Treatment of a lacrimal gland tumor include local and distant control of the
disease and maintaining the vision of the patient, when possible. Improvements
have been made in the understanding these neoplasms since the use of
the classification of salivary gland tumors has been applied to epithelial
lacrimal gland tumor. Adjuvant intensity modulated radiation therapy (IMRT),
Radioimmunotherapy, proton beam therapy and intra-arterial chemotherapy
may constitute the most promising advancement for management of malignant
carcinoma of lacrimal gland.

Use of Hy Drogels in Orbital Surgery
Guthoff Rudolf F.
1. University of Rostock, Eye Department
WOC2012 Abstract Book
Self inflating osmoexpanders (co-polymers based on methyl methacrylate and
n-vinyl pyrrolidone) are increasing their volume by water uptake 8 to 10 folds.
They are included in the treatment of congenital clinical anophthalmus as
socket expanders (half spheres), orbital expanders (spheres) and pellets. The
latter can be also applied in any kind of volume deficiency after enucleation.
They are directed in the target tissue area minimal-invasively via tocar-canulas
of 2 mm in diameter.

Strabismus and Graves Disease
Schittkowski Michael (1)
1. University Medicine Goettingen
Strabismus in thyroid ophthalmopathy is based on contractility and distensibility
loss of external ocular muscles. Recession of the restricted inferior or
internal rectus muscle is precise, safe and effective in patients with thyroid
ophthalmopathy. In selected cases a fadenoperation might be helpful to further
improve the fusional visual field. If an orbital wall decompression is indicated it
should be performed before strabismus surgery. Lid surgery should be the last
step in surgical therapy.

Surgery of Lagophthalmos
Adenis Jean-Paul (1)
1. Chu Dupuytren
Various techniques can be used as ‹ static ‹ procedures in long standing facial
palsy with lagophthalmos and in cases of failure of nerve anastomosis:
• Inner canthoplasty
• Outer canthoplasty or both
• Upper eyelid lenghthening
• Brow lift
• Gold weight implants
• Tarsorraphy
In case of failure of the previous techniques or in ICU patients indications and
associations of the techniques will be discussed.

How to Avoid Redo in DCR Surgery
Ntountas Yannis (1)
1. 1st Eye Clinic University of Athens
The prevention of complications in Dacryocystorhinostomy begins before the
actual surgery, during the presurgical examination and diagnosis of the patient.
Preoperative dacryocystography, excision of scar tissue in the area of common
canaliculus, rhinostomy large enough, the use of traction sutures in the anterior
flaps and as well as of anti-metabolites and even the correct patient/ surgeon
positioning during surgery avoiding post-operative sump syndrome, are some
of the tips in aim to avoid to redo a DCR surgery.
