What Tests are Most Sensitive for Follow-up?
Tomey Karim (1)
1. Beirut Eye Specialist Hospital
The importance of regular follow-up in glaucoma cannot be overemphasized.
In addition to clinical testing and careful monitoring of pressure fluctuations, it
is important that the progression of damage be monitored through objective
testing. While biomicroscopic disc assessment (and photography) is still
a valuable tool, the various objective tests available nowadays play an
equally important role in the early detection, quantification, and monitoring
the progression of subtle degrees of damage. The choice of a particular test
depends on several factors. Perimetry may not detect early or subtle damage;
it has been well documented that a significant percentage of retinal nerve
fibers can be lost before any field defects appear. Therefore, in glaucoma
suspects, for example, perimetry is not the procedure of choice. Modern optic
nerve and retinal nerve fiber layer imaging devices have proven their ability
to reveal the earliest and most subtle degrees of glaucomatous damage, with
good sensitivity and specificity. On the other hand, perimetry is more useful
than imaging devices for the follow-up of advanced cases. The choice of a
particular test or device also depends on factors other than the stage of the
disease, such as media clarity, the presence of retinal pathology, and patient
cooperation.

Disc Hemorrhages and Parapapillary Atrophy
Gustavo De Moraes Carlos
These two features of glaucomatous optic neuropathy have been consistently
shown to be significant and independent risk factors for glaucoma progression.
Disc hemorrhages and beta-zone parapapillary atrophy are clinical signs that
do not require any sophisticated or expensive methods for detection. However,
they are often missed and this may preclude more intense treatment to halt
or slow progression. Frequent documentation of the optic disc and use of a
standardized method to evaluate the optic nerve complex can minimize this
chance and improve quality of glaucoma care.

The Optic Nerve Complex in 3 Dimensions
Park Sung Chul (1)
1. New York Eye and Ear Infirmary
Optic nerve complex consists of optic nerve head and peripapillary structures
including parapapillary atrophy, retinal/choroidal/intrascleral vessels, and
peripapillary subarachnoid space. Enhanced depth imaging OCT is useful in
evaluating these structures in pathologic conditions including glaucoma, optic
nerve head drusen, optic disc pit, and unspecified anomalous discs. In this
talk, high-resolution OCT images and 3-dimensional reconstructions of various
pathologic conditions will be demonstrated, and detailed strategies for better
evaluation and monitoring of those conditions will be discussed.

Digital Image Devices and Stereo-Phothographs: Which is Better?
Susanna Jr. Remo (1)
1. Faculdade de Medicina da Universidade de Sao Paulo
The evaluation of the optic nerve head (ONH) and retinal nerve fiber layer
(RNFL) is fundamental for glaucoma diagnosis. Limitations in clinical
assessment of this structure may be related to normal anatomical variability
and level of experience. Computerized imaging devices such as scanning
laser ophthalmoscope, scanning laser polarimetry and optical coherence
tomography, have been proposed as alternative methods to help the clinician
in glaucoma diagnosis. This presentation will focus in how and when digital
image devices should be use, their pitfall related to stereo-photos and viceversa.

Imaging Devices and Their Structural-Functional Correlation
Tomey Karim (1)
1. Rizk Hospital
Imaging devices in glaucoma are supposed to detect very early and subtle
damage, before any abnormalities appear clinically or on perimetry. Such
devices focus primarily on studying the integrity of the retinal nerve fiber
layer within the neural rim or around the disc. Other parameters include disc,
cup, and rim areas or volumes, and their various ratios. Emphasis in this
presentation will be on GDx-type devices and their strengths and weaknesses
in early diagnosis and follow-up, plus the possible sources of error.

Kpro: Experience and Complications
Vargas Jose Manuel (1)
1. ALACCSA-R
Purpose: To evaluate and report the outcomes after Boston Keratoprosthesis
implantation.
Participants: 50 eyes with corneal and ocular surface diseases that were
ineligible for penetrating Keratoplasty.
Results: 92 % achieved improved vision after surgery.
Preoperative Diagnosis: Included failed cornea transplants, chemical injury,
stem cells deficiency and aniridia.
Complication: Glaucoma, GDD erosion, retoprosthetic membrane,
endophthalmitis and corneal melt were observed
Conclusion: Boston Keratoprosthesis seems to be a viable option in cases of
poor prognosis for primary penetrating Keratoplasty.

Crosslinking Long-Term Results and Complications
Scorcetti Daniel
Crosslinking is a new horizon in the treatment of corneal ectasia for the
ophthalmologist and patient. After more than a decade, we know that freezing
in the development, the improvement in topographic and aberrometer indices
and the very low incidence of complications and adverse effects allows a
radical change in the visual expectations and therapeutic indications, so the
need for keratoplasty decreases dramatically. The Corneal Crosslinking is here
to stay.
