Recent missions on board the International Space Station have revealed previously unreported physiological consequences of long duration space flight, particularly in eyesight, and in this Brief Dr. Seedhouse reviews the existing theories on what causes this degeneration and how long it will last. Notably, 60% of long-duration crews have reported subjective degradation in vision, a clear indication that further study is necessary before astronauts embark on even longer-term space missions. Decreased near-visual acuity was reported in 46% of ISS/Mir crewmembers, resulting in a change of up to 2 dioptres in their refractive correction. It is possible that ophthalmic changes have been present since the first days of spaceflight, but had been attributed to other causes; this approach to the issue as well as other hypotheses are all presented in full to give a broad foundation of the existing knowledge on the topic. The changes have occurred at various times during a mission with varying degrees of visual degradation. Some cases resolved on return to Earth, but several crewmembers have not regained pre-flight visual acuity, indicating the damage may be permanent. One explanation of the syndrome has been attributed to hyperopic shift due to aging, but onboard analysis techniques, including visual acuity assessments, retinal imagery, and ultrasound examination of the eye, has led to the acceptance of a wider syndrome. In addition to vision changes, studies have reported flattening of the globe, swelling of the optic disc (papilledema), choroidal folds in the retina, swelling of the optic nerve sheath, and visual field defects. It is widely hypothesized that this spectrum of symptoms may be explained by an elevation of intracranial pressure (ICP). Establishing the provenance of this medical problem, monitoring its occurrence and resolving the symptoms for future long term space missions is a key challenge for space medicine. With this book, readers have an entry point for understanding the full scope of the problem and its possible origins.

Muller cells may be used in the future for novel therapeutic strategies to protect neurons against apoptosis (for example, somatic gene therapy), or to differentiate retinal neurons from Muller/stem cells. Meanwhile, a proper understanding of the gliotic responses of Muller cells in the diseased retina, and of their protective vs. detrimental effects, is essential for the development of efficient therapeutic strategies that use and stimulate the neuron-supportive/-protective - and prevent the destructive - mechanisms of gliosis.

We are excited to bring together recent research on the molecular biology of Axenfeld-Rieger syndrome (ARS) disorders. In the following chapters we will review and provide direct evidence for the molecular basis of this group of heterogeneous disorders, which include Rieger syndrome and Rieger anomaly. While ARS patients were initially diagnosed in the early 1930s the genetic basis for ARS was unknown until the recent identification of chromo- somal loci associated with this genetic disorder. In the mid-1990s Drs. Jeffrey C. Murray and Elena V. Semina identified PITX2 through positional cloning tech- niques as a gene associated with ARS. These researchers were able to iden- tify point mutations in PITX2 that were linked with ARS patients. ARS patients presented clinically with several developmental anomalies that fur- ther provided clues about the function of the PITX2 homeobox tran- scription factor. The phenotypic variability of ARS patients indicates that PITX2 can participate with many other faaors to control normal development processes. The hallmarks of ARS developmental anomalies are eye, tooth and umbilical defects. However, abnormal pituitary, heart, and craniofacial development are also detected. Thus, ARS patients provided the first link of PITX2 involvement in the development of these organs and structures. Some of these anomalies are recapitulated in epigenetic and genetic mouse, chick, zebrafish and frog studies which will be reviewed in the following chapters.

The global medical and scientific communities need to standardize methodologies and agree on minimum criteria to permit inter-study comparisons. This book develops such standards, presenting a series of recommendations that represent the first codification of the manner in which studies should be executed.

"No attainment is ever final" Vascular disorders of the optic disc and nerve are important not only to the ophthalmologist but also to the neurologist and the internist. To the first specialty group they represent one cause of blindness or severe visual impairment; to the second group the optic disc edema and optic atrophy seen in these disorders can pose serious problems of diagnosis, or give indica tions of the involvement of the cerebral circulation; while to the last group they are frequently indicative of systemic disease, particularly of the cardiovas cular system. Recent advances in our knowledge of the blood supply of the optic nerve head have shed a significant new light on the subject. With the recent advent of fluorescein fundus angiography, an extra dimension has been added to the study of the ocular and optic disc circulations, and we have entered into a new era in the understanding of ocular vascular disorders "in vivo". In the pre-angiography era, postmortem injection studies, although very valuable, did not completely reveal the vascular pattern of the optic disc in the living, in health, and disease. The ophthalmoscope, without doubt, has been valuable in assessing optic disc lesions, but could not give us informa tion on the circulation of the eye and optic disc "in vivo".
