Syphilis is a sexually transmitted infection caused by the spirochete Treponema pallidum. Ocular involvement can occur at any time, and it may affect 10% of patients in secondary stage, from 2% to 5% tertiary stage. Uveitis most common presentation ocular syphilis, affecting 0.4% 8% with systemic disease. Chorioretinitis posterior alteration. We present case 53-year-old male patient, presenting...

Highly pathogenic avian influenza (HPAI) H7 virus infection in humans frequently results in conjunctivitis as a major symptom. However, our understanding of what properties govern virus subtype-specific tropism, and of the host responses responsible for eliciting ocular inflammation and pathogenicity following influenza virus infection, are not well understood. To study virus-host interactions ...

Managing the inflamed or infected eye in the emergency setting presents a diagnostic and therapeutic challenge to the emergency physician; the causes and prognoses range from benign, self-limited illness to organ-threatening pathology. A careful history, with attention to comorbid illnesses and time course, is paramount, as is knowledge of the complete ophthalmologic examination. Much of the or...

Equine herpesvirus myeloencephalitis (EHM) remains one of the most devastating manifestations of equine herpesvirus type 1 (EHV-1) infection but our understanding of its pathogenesis remains rudimentary, partly because of a lack of adequate experimental models. EHV-1 infection of the ocular vasculature may offer an alternative model as EHV-1-induced chorioretinopathy appears to occur in a signi...

Methods The ocular samples viz., corneal swab, corneal scraping, aqueous tap and vitreous tap were processed for culture and the isolated Nocardia species were further confirmed for speciation by standard microbiological procedures. Antibiotic susceptibility analysis for the confirmed isolates of N. asteroides was performed by agar disk diffusion method following the guidelines of Clinical Labo...

Ocular toxoplasmosis is commonly attributed to prenatally acquired (congenital) infection unless there is clear evidence that infection was acquired postnatally. We challenge this view by comparing the risks of ocular disease caused by prenatal and postnatal toxoplasmosis. As the history, clinical appearances, and serological findings associated with the two aetiologies are frequently indisting...

Experimental ocular infection of specific-pathogen-free cats with the feline pneumonitis strain of Chlamydia psittaci produced an acute, severe conjunctivitis characterized by blepharospasm, conjunctival hyperemia, chemosis, and ocular discharge. Organisms were recovered from the conjunctiva for several weeks, and persistent genital and gastrointestinal infection also resulted from the ocular i...

Ocular flutter is an eye movement disorder characterized by purely horizontal rapid saccadic oscillations lasting for a few minutes which stops spontaneously. Postinfectious ocular flutter and truncal ataxia are a rare entity. There are reported cases of opsoclonus myoclonus ataxia in association with dengue virus infection. However, there are no reported cases of parainfectious ocular flutter ...
