The higher percentage of centrally located corneal ulcers might be due to exophthalmia
which prevents normal palpebral apposition and leads to lagophthalmos and ultimately leads to uneven distribution of tear film at central region of cornea.
On admission to our hospital, physical examination revealed severe jaundice, tremor and exophthalmia
. His AST was 84 U/L, ALT 131U/L, total bilirubin 21 mg/dl, ANTI-HAV IgM positive, serum free [T.sub.3] 10.95 ng/dl (2.0 - 4.4 ng/dl), serum free [T.sub.4] 4.18 ng/dl (0.93 - 1.7 ng/dl) and TSH < 0.05 [micro]IU/L (0.27 - 4.2 [micro]IU/L).
The signs and symptoms of hyperthyroidism can include nervousness, heat intolerance, tachycardia, palpitations, goiter, weight loss, thyromegaly, exophthalmia
, increased appetite, nausea and vomiting, sweating, and tremor.
The live and whole fish from which GBS ST283 was recovered did not show corneal opacity or exophthalmia
, suggesting this strain may not be pathogenic to freshwater fish
Other side effects associated with corticosteroids administered via different routes include: topical--blurred vision, allergy and punctate keratopathy; periocular--proptosis, central retinal artery occlusion and haemorrhage; intraocular --vitreous floaters and retinal detachment; and systemic myopia and exophthalmia
Diseased fish may display nonspecific clinical signs in the early stages of infection, including rapid onset of mortality (which can reach up to 100% in fry), lethargy, darkening of the skin, exophthalmia
, anaemia (pale gills), haemorrhages at the base of the fins, gills, eyes and skin, and a distended abdomen due to oedema in the peritoneal cavity.
: It was diagnosed in a 4 month old female calf which was characterized by protrusion of eye ball following blunt trauma in nature (Fig.
On examination of the head and neck, there was a prominent frontal bone, open and flat forehead, microcephaly, sparse hair, hypertelorism, shallow orbits, exophthalmia
, blue sclerae, megalo cornea, fuzzy corneas, malar hypoplasia, nasal hypoplasia, depressed nasal bridge, low and and rear-positioned ears, malformed helices, complete cleft lip, complete cleft palate and short neck.
resulting from resulting from orbital invasion of the tumor and vision loss due to optic nerve and nervous central system may be seen, as well as posterior segment abnormalities, such as retinal hemorrhages and retinal detachment.
Also specimens having clear signs of barotrauma such as gas filled eyes (exophthalmia
) or overinflated abdomens due to punctured gas-bladders are poor candidates for live storage and should be removed.
