Neuro-ophthalmological abnormalities in neurological diseases of dogs and cats: a retrospective study of 114 cases (2010-2015)

The current retrospective study includes 99 canine and 15 feline cases with neurologic disease accompanied by neuro-ophthalmological abnormalities (blindness, strabismus, nystagmus, anisocoria, miosis, mydriasis, Horner’s syndrome). All cases were presented in the Companion Animal Clinic of the School of Veterinary Medicine – Faculty of Health Sciences (Aristotle University of Thessaloniki) over a six-year period (2010-2015). The most frequent presenting complaints were head tilt (n=22/99) and paresis/paralysis (n=22/99) in dogs and head tilt (n=3/15) and ataxia (n=3/15) in cats. The most common neuro-ophthalmological abnormalities were strabismus (n=55/99) in dogs and anisocoria (n=7/15) in cats. The localization of lesions was found to be multifocal (n=38/99), and focal, in the vestibular system (n=37/99) in dogs, whilst in cats it was solely multifocal (n=6/15). An etiological diagnosis was reached only in 48 dogs and 10 cats; the former were mainly diagnosed with distemper encephalitis (10/48) and congenital hydrocephalus (6/48) and the latter mostly with encephalitis (n=5/10). Neuro-ophthalmological cases reached a 18.24% of the total neurologic case load (n=625) admitted during a six-year period. Neuro-ophthalmological examination as well as the correlation of the observed abnormalities with the overall neurological symptomatology is important for the neuroanatomic diagnosis, the assessment of severity and prognosis of the respected mainly diseases

The Antiangiogenic Properties of Adipose-Derived Mesenchymal Stem/Stromal Cells in Corneal Neovascularization in a Rabbit Model

The purpose was to study the anti-angiogenic effect of adipose-derived mesenchymal stem/stromal cells (ADMSCs) on experimentally induced corneal injuries. Corneal neovascularization (NV) was induced by incising and subsequently suturing the corneal surface in 32 New Zealand rabbits. Following suturing, the rabbits were randomly allocated into 2 groups, and received either phosphate-buffered saline (PBS) (control) or ADMSCs, both administered via three different routes. Digital images of the cornea were obtained two weeks post-incision to measure the area of neovascularized cornea. Tumor necrosis factor (TNF) was immunohistochemically assessed in the both groups. The corneal tissue was evaluated for vascular endothelial growth factor (VEGF). The extent of corneal NV in all eyes was assessed photographically by an independent observer. Fourteen days after the incisions, the degree of corneal NV was substantially decreased in the ADMSC-treated group (1.87 ± 0.9 mm2, 1.4 % ± 0.67 % of corneal surface) compared to the control and PBS-treated group (4.66 ± 1.74 mm2, 3.51 % ± 1.31 %, p < 0.001). ADMSCs significantly decreased injury-induced corneal NV in New Zealand rabbits two weeks post-treatment. This strategy has potential for use in the control of corneal NV in vivo.Â
