Postmortem Finding

Hyphema (hemorrhage within the anterior chamber of the eye) can be caused by several mechanisms and can easily be detected in routine ophthalmic or necroscopic examination as discolored red eye(s). The purpose of this study is to report the cause of hyphema diagnosed as a postmortem finding in dogs and cats. Twenty cases, 14 dogs and six cats of several ages and breeds and of both sexes were included in the study. Hyphema presented as a unilateral (14 cases out of 20) or bilateral (6/20) disorder in dogs and cats and extension of hemorrhage varied from minimal to diffuse. Hyphema was secondary to systemic disease (15/20) or occurred as a primary ocular lesion (5/20) in four dogs and one cat. Primary hyphema was always unilateral. In four of these cases, the cause of hyphema was trauma and remaining case was caused by phacoclastic uveitis in a dog with bilateral hypermature cataract. Various causes of bleeding disorders were found related to secondary hyphema: in decreasing order of frequency, they included vasculitis (8/15), systemic hypertension (5/15), and acquired coagulopathies (2/15). Vasculitis due to feline infectious peritonitis accounted for half of the cases (n=3) of systemic hyphema in cats. The various pathological aspects and pathogenesis of hyphema in dogs and cats are described and discussed.

1. In a large number of experiments with Gammarus chevreuxi when the animals were kept under similar conditions at temperatures ranging from 20° to 28° C., twenty instances occurred in which red-eyed mutations appeared independently and simultaneously. The most important of these (Mutant Stock V) is described in detail in this paper.2. The Red eyes which have arisen in this Stock V and in the four previous Stocks, I to IV, have proved to be all genetically distinct from one another.3. There are at leadt two different classes of “red-eye,” the one simple, the other with intermediate stages. Mutant Stock V, here described, represents the second type. Differences in the method of origin of the two classes have been pointed out.4. The inheritance of the red-eyedness of the second class—namely, that in which intermediate stages and various colour changes occur—is of a complicated kind. For an interpretation in terms of Mendelian genes, even if allowance is made for an extent of variation in members of one particular genotype, clearly several of them are involved. Further, there must be considerable interplay of one kind or another among the different genes.5. Although so many different colour shades have appeared in Mutant Stock V, all can be interpreted in terms of varying concentrations of two pigments—the black and the red. Dilute black pigment with little or no red gives a purple eye.

Red Eyes

In this study, we compared the assessment of remote smartphone photographs to in-office exams in the diagnosis of two groups of external eye diseases, red-eye pathology and post-operative eyelid surgery complications. Participants were examined and received an in-office diagnosis by either a corneal or oculoplastic specialist. After viewing an educational video on smartphone photography, the patient’s companion then took a series of standardized photographs. Two additional corresponding specialists then made a separate diagnosis via the interpretation of only smartphone images and the patient’s history. ‘Remote’ and in-office diagnoses were compared using a kappa test for agreement. The remote and in-office diagnoses were in agreement for 27 of 28 eyes, representing a chance-corrected Kappa agreement rate of 93% (95% confidence interval: 79–99%). Among the 16 red eyes, the diagnoses were in agreement for 15 of 16 red eyes, representing a chance-corrected Kappa agreement rate of 92% (95% confidence interval: 77–99%). Among the 12 eyes with post-operative eyelid surgery complications, the diagnoses were in perfect agreement. Our results suggest that the diagnosis of 1) red-eye pathology and 2) post-operative eyelid surgery complications based on smartphone images may be comparable to in-office exams.

Sometimes in Flash Photography red colored patches occurred in human eyes. It is actually a reflection of bright flash light reflected from blood vessels in the eyes, giving the eye an unnatural red hue. Red-eye is a big problem in professional photography. Most red-eye reduction systems in many editing software needed the user to identify the red-eye and make an outline through the red-eye. Here we propose an Automatic Red-Eye Detection System instead. The system contains a red-eye detector that finds bunch of red pixels those are clustered to gather, a state of face detector that used to eliminate most false positives (pixel clusters that look red eyes but are not); and a redeye outline detector. All three detectors are automatically learned from the taken datasets and with a proper classifiers using boosting. For creating a fully Automatic Red-Eye Corrector this system needed to be combined with a functional Red-Eye Reduction model.

Feline Coronavirus

Feline coronavirus (FCoV) is an enveloped single-stranded RNA virus, of the familyCoronaviridaeand the orderNidovirales. FCoV is an important pathogen of wild and domestic cats and can cause a mild or apparently symptomless enteric infection, especially in kittens. FCoV is also associated with a lethal, systemic disease known as feline infectious peritonitis (FIP). Although the precise cause of FIP pathogenesis remains unclear, some hypotheses have been suggested. In this review we present results from different FCoV studies and attempt to elucidate existing theories on the pathogenesis of FCoV infection.

Abstract Background Feline Infectious Peritonitis (FIP) is a fatal, systemic disease caused by a mutant form of Feline Infectious Peritonitis virus (FIPV) and has been reported to occur worldwide in domestic cats and massive wild feline species. Meanwhile a definitive diagnosis of FIPV ante mortem remains challenging. The objective was to develop a qPCR for the detection of FIPV in cats and applied the assay to detected the viral loads in different autopsied organs of a cat naturally infected with FIPV. Results: After genetic comparison, We develop a SYBR Green I based quantitative transcription PCR assay (qPCR) targeting the structural protein N of FIPV. The sensitivity of the new assay in detecting FIPV nucleic acids was approximately 1000 times higher than that of the conventional RT-PCR assay (PCR). There were no cross-reactions with other common viruses. Organ assay showed that FIPV were present in the Heart, liver, spleen, lung, kidney, duodenal and ascites of the autopsied cat. Histological lesions showed that macrophages, non-toxic neutrophils and lymphocytes predominated in different organs which confirmed that the cat was infected with FIPV. Conclusions We developed a quantitative platform for epidemiological investigations study of FIPV that was simple, sensitive, and rapid.

Hereditary Transthyretin Amyloidosis

AimsTo investigate the relationship between the ophthalmic and systemic phenotypes in patients with hereditary transthyretin amyloidosis with the S77Y mutation (ATTRS77Y).MethodsIn this cross-sectional study, patients with genetically confirmed ATTRS77Y amyloidosis were enrolled. All patients underwent complete neurological examination, including staging with the Neuropathy Impairment Score (NIS), Polyneuropathy Disability (PND) score; complete cardiological evaluation, including echocardiography, cardiac MRI and/or cardiac scintigraphy and complete ophthalmic evaluation, including slit lamp examination and fundus examination. Ocular ancillary tests (fluorescein and indocyanine green angiography, and anterior segment optical coherence tomography) were performed in cases with abnormal findings. The Kruskal-Wallis test was used for quantitative outcomes and Fisher’s exact test for qualitative outcomes. Statistical significance was indicated by p<0.05 (two tailed).ResultsThe study sample was composed of 24 ATTRS77Y patients. The mean patient age was 58.4±12.4 years. None of the patients presented with amyloid deposits in the anterior chamber, secondary glaucoma or vitreous amyloidosis. Retinal angiopathy was observed in four patients, complicated with retinal ischaemia in one patient. Conjunctival lymphangiectasia (CL) was detected in 13 patients (54%), associated with perilymphatic amyloid deposits. The presence of CL was statistically associated with more severe neurological disease (NIS=43.3±31.9 vs 18.9±20.4; PND=2.6±1.0 vs 1.4±0.7 in patients with and without CL, respectively; both p<0.05) and amyloid cardiomyopathy (p=0.002).ConclusionIn ATTRS77Y patients, CL is common and could serve as a potential biomarker for severe systemic disease. There were neither anterior chamber deposits, secondary glaucoma nor vitreous deposits in ATTRS77Y patients.

Red Eyes

A patient with red eyes and ocular decongestants drops (tetrahidrozolyne 0.05%) use history, was observed by an optometrist and referred to an ophthalmic consult. The redness of their eyes was secondary to conjunctival vessel micro-hemorraghe (petechiaes). After a complete ophthalmology and hematologist exploration a Cell Sickle Disease was diagnosed as the cause of the vascular disorder. An hematologist treat it and the ocular redness was resolved. This case emphasizes the problem about self-medication and remark the importance of the optometrist working together with the ophthalmologist to prevent ocular complains as well as systemic disease.
