Using Multivariate Analyses To Explore Disease Progression of Finch Mycoplasmosis.

J Wildl Dis 2021 May 12. Epub 2021 May 12.

Department of Ecology, Evolution, and Organismal Biology, Iowa State University, 251 Bessey Hall, 2200 Osborne Drive, Ames, Iowa 50011, USA.

Lesion severity scales have been developed for a number of wildlife diseases causing external pathology. Perhaps the best known and most widely used scoring system has been developed for finch mycoplasmosis in which observers measure conjunctival pathology along a four-point scale of increasing severity. We developed novel techniques to characterize variation in host phenotype based on occupancy of multidimensional trait space (disease space). Read More

Changes in peri-ocular anatomy and physiology in pseudoexfoliation syndrome (Review).

Exp Ther Med 2021 Jun 19;21(6):650. Epub 2021 Apr 19.

Laboratory of Clinical Virology, Medical School, University of Crete, Heraklion 71003, Greece.

Pseudoexfoliation syndrome (PEX) is characterized by the deposition of proteinaceous material in the anterior ocular segment (resulting in ophthalmic pathologies such as glaucoma and increased risk of complications in cataract surgery), but also by several systemic manifestations. The involvement of peri-ocular tissues in PEX, including the eyelid skin, lacrimal gland, conjunctiva, orbital fat and vessels, as well as the optic nerve, has been reported by several previous studies. The peri-ocular effects of PEX include the development of eyelid laxity, conjunctival chalasis, tear film abnormalities, pronounced orbital fat atrophy in response to the administration of prostaglandin analogues in pseudoexfoliative glaucoma, deficient orbital vascular supply and biomechanical changes in both the eyeball and the optic nerve.
