Structure and Biomechanics of the Lamina Cribrosa
Park Sung Chul (1)
1. New York Eye and Ear Infirmary
The optic nerve head (ONH) including the lamina cribrosa is a weak spot within
an otherwise strong corneo-scleral envelope. The lamina cribrosa provides
structural and functional support to the RGC axons. In this talk, current
knowledge on ocular biomechanics, how mechanical forces and the resulting
deformations are distributed in the ONH, will be reviewed. Also, detailed
ONH anatomy including landmark microstructures, which are crucial for
understanding current concept of lamina cribrosa biomechanics, will be
revisited.

Ocular Biomechanics and Ocular Blood Flow
Pillunat Lutz
The knowledge of changes in ocular perfusion and in biomechanics of the optic
nerve head (ONH) with age is important for a better understanding of changes
in glaucoma. With increasing age blood flow will be reduced and causes a
reduction of the blood supply of the ONH. The LC is stressed by increased
IOP or fluctuations of IOP which leads to biomechanical changes. With age
this stress induced form change is not favourable, possibly due to a reduced
flexibility.

Venous Ocular Pressures in Glaucoma
Jonas Jost (1)
1. Department of Ophthalmology
To determine central retinal vessel collapse pressure in chronic open-angle
glaucoma, we studied 19 glaucomatous eyes and 27 control eyes. Central
retinal vessel collapse pressure was measured by a Goldmann contact lens
fitted with a pressure sensor in its holding grip. Central retinal vein collapse
pressure was significantly (p=0.001) higher in the glaucoma group than in the
control group (26.1+/-26.4 versus 6.1+/-8.4 rel. units). Measured by a new
ophthalmodynamometer, central retinal vein collapse pressure measurements
may be abnormally high in eyes with chronic open-angle glaucoma.

Therapeutic Options to Treat Vascular Factors in Glaucoma
Orgül Selim (1)
1. Eye Clinic of the University Hospital Basel
Large scale studies have demonstrated that blood flow alteration is an
important factor in determining whether glaucomatous optic nerve
damage occurs and/or progresses. This information has not yet lead to the
implementation of a specific treatment with a clear benefit for the patients. The
role of altered blood flow should probably not be discussed without considering
the specific structural optic nerve changes in glaucoma. Understanding this
relationship may help design a proper treatment related to blood flow in
glaucoma.

Glaucoma Progression and Ocular Blood Flow
Kook Michael (1)
1. Asan Medical Center
Several studies have shown a positive relationship between glaucoma
progression and disturbed ocular blood flow. Unfortunately, many of
these studies lack uniformity in methodology, imaging technology, patient
characteristics, and other aspects. Despite these shortcomings, nearly majority
of the studies suggests that vascular insufficiency might be related to glaucoma
development and progression. In this presentation, various limitations and
issues to be resolved as well as current leading evidences surrounding the
role of ocular blood flow on glaucoma progression will be discussed.

Arterial Blood Pressure and Glaucoma Damage
Schmetterer Leopold
Glaucoma is a progressive optic neuropathy of unknown origin. Increased
intraocular pressure is the most important risk factor for the disease. In addition,
low ocular perfusion pressure and low systemic blood pressure was also found
to be associated with glaucoma risk. The present talk provides a concept of
the pathophysiology of glaucoma based on these findings. In addition, the
diagnostic and therapeutic consequences are discussed.

Glaucoma in Developing Countries: Issues and Challenges
Wilson M. Roy (1)
1. Hamilton Eye Institute/ University of Tennessee Health Science Center and
St Jud
There are many critical unmet needs in caring for glaucoma in developing
countries, and non-governmental agencies assume an important role in
providing technology and infrastructure support. This lecture will focus
on the distribution of glaucoma and glaucoma-related blindness between
developed and developing economy countries and will examine the relative
socioeconomic burden of glaucoma. Critical needs and barriers to establishing
national vision plans will be assessed. Possible solutions to decreasing the
burden of glaucoma in the developing economy countries will be discussed.

This session will describe the various types of glaucoma surgeries available in
Nigeria. It would focus on the most popular glaucoma surgery, the indications,
techniques, complications and management in a typical West African country.
It would also give an overview of the outcomes of trabeculectomy in Nigeria
and an insight into the future of glaucoma surgeries in Nigeria. Main learning
outcome Participants will learn the past, present and the future of glaucoma
surgeries in Nigeria.
