The ocular lesions of bovine malignant catarrhal fever were characterized in 15 naturally occurring and eight experimentally induced cases of the disease. Consistent findings included: lymphocytic vasculitis of retinal, scleral, posterior ciliary, and uveal vessels; uveitis, especially involving ciliary processes, ciliary body, and iris; and keratitis with corneal edema, neovascularization, and epithelial and endothelial degeneration. Lymphocytic ciliary neuritis and optic meningitis were found less frequently. Ultrastructural examination of the ciliary body and iris from one experimental calf confirmed that most infiltrating mononuclear cells were lymphocytes. The uveitis, vasculitis, and keratitis of malignant catarrhal fever were probably immune-mediated.

Clinical cases of 60 patients with acanthamebic keratitis examined by biomicroscopy and of 22 patients largely examined by confocal microscopy are generalized. Acanthamebic keratitis is a slowly progressing infectious lesion of the cornea, which is caused by acanthamebas freely residing in soil and water. Contaminated contact lenses are the key risk factor. The main clinical features of acanthamebic keratitis are defined; they are presence of risk factors; a unilateral lesion in young, healthy and immune-competent persons; a typical clinical pattern of surface keratitis mainly of the ring shape; corneal neuritis without corneal neovascularization but with a severe pain in the eye; and a slow chronic clinical course, i.e. lasting for several weeks and months. Confocal microscopy is the most effective and fast diagnostic tool because it ensures the detection of acanthamebic cysts and trophozoids in all strata of the corneal stroma. The authors isolate, within the clinical course of acanthamebic keratitis, 5 stages; they are surface epithelial keratitis; surface epithelial punctate keratitis; stromal ring-shaped keratitis; ulcerous keratitis; and keratoscleritis.

The aim of five years (2000-2005) study was to investigate the peculiarities of Herpes Zoster in immunocompromised and immunocompetent patients. For this purpose we have investigated the clinical course of Herpes Zoster, disease duration, complications of disease, as in acute phase as well as postherpetic neuralgia in 74 HIV positive (1st group) and 74 HIV negative (2nd group) groups of patients. In both group of patients we have studied the prevalence of the following complications: 1. Acute complications of Herpes Zoster: a) Neurological: motor neuropathy, cranial neuritis, meningoencephalitis, transverse myelitis. b) Ophthalmic: keratitis, iritis, retinitis, visual impairment c) Cutaneous: bacterial superinfection, scarring, disfigurement. d) Visceral: pneumonitis, hepatitis. e) Multidermatomal. 2. The complications of after resolution of infection: a) Postherpetic neuralgia and various duration of pain associated with postherpetic neuralgia such as : < month, 1-6 months, 6-12 months and >1 year durations. b) Recurrent herpes zoster. Herpes Zoster infection was diagnosed based on clinical symptoms and by detection of VZV specific IgM and IgG by ELISA. HIV infection was diagnosed by ELISA method and was confirmed by Western Blot. We found that Herpes Zoster may develop as in HIV positive as well as HIV negative population. Study showed that severe cases of disease (Herpes Zoster), long duration and rate of complications are much higher in HIV/AIDS than in HIV negative group patients. Rate of hospitalization is also higher in HIV/AIDS patients with Herpes Zoster than in HIV negative patients with Herpes Zoster. Frequency of recurrent Herpes Zoster is much higher in HIV/AIDS patients than in HIV negative patients. The postherpetic neuralgia is very frequent complication for both group (HIV positive and HIV negative) Herpes Zoster patients, but its duration longer in HIV/AIDS patients in comparison HIV negative group. There were no significant difference in disease severity, duration and complications among male and female patients.

Onchocerciasis is caused by the parasitic worm Onchocerca volvulus, which releases millions of offspring (microfilariae). Microfilariae migrate through the skin and can enter the anterior or posterior regions of the eye. While alive, the microfilariae appear to cause little or no inflammation, being in the anterior chamber. However, when they die, either by natural attrition or after chemotherapy, the host response to degenerating worms can result in ocular inflammation (keratitis, uveitis, chorioretinitis, neuritis of the optic nerve) that causes progressive loss of vision and ultimately leads to blindness. With the use of a mouse model of corneal inflammation to study the pathogenesis of ocular onchocerciasis by injecting worm extracts directly into the corneal stroma, it was found that worms treated with the antibiotic doxycycline, which destroys Wolbachia, induced lower corneal stromal thickness and stromal haze (indicators of corneal oedema and opacity) and neutrophil infiltration compared with both untreated worms and worms that do not harbour Wolbachia. These data indicate that endosymbiotic Wolbachia bacteria in filarial parasites have a key role in the pathogenesis of river blindness. Worms recovered from patients treated for 6 weeks with doxycycline contained fewer Wolbachia bacteria and had abnormal embryogenesis, indicating a role for Wolbachia in the survival or fecundity of the worms. Antibiotic treatment may also reduce the severity of the inflammatory response in the cornea.

The transfer factor (TF) was described in 1955 by S. Lawrence. In 1992 Kirkpatrick characterized the specific TF at molecular level. The TF is constituted by a group of numerous molecules, of low molecular weight, from 1.0 to 6.0 kDa. The 5 kDa fraction corresponds to the TF specific to antigens. There are a number of publications about the clinical indications of the TF for diverse diseases, in particular those where the cellular immune response is compromised or in those where there is a deficient regulation of the immune response. In this article we present our clinical and basic experiences, especially regarding the indications, usage and dosage of the TF. Our group demonstrated that the TF increases the expression of IFN-gamma and RANTES, while decreases the expression of osteopontine. Using animal models we have worked with M. tuberculosis, and with a model of glioma with good therapeutic results. In the clinical setting we have worked with herpes zoster, herpes simplex type I, herpetic keratitis, atopic dermatitis, osteosarcoma, tuberculosis, asthma, post-herpetic neuritis, anergic coccidioidomycosis, leishmaniasis, toxoplasmosis, mucocutaneous candidiasis, pediatric infections produced by diverse pathogen germs, sinusitis, pharyngitis, and otits media. All of these diseases were studied through protocols which main goals were to study the therapeutic effects of the TF, and to establish in a systematic way diverse dosage schema and time for treatment to guide the prescription of the TF.

In this paper, we review sexually transmitted diseases (STD) involving the eye. Recently conjunctivitis due to Chlamydia trachomatis in children and adults is increasing, and that of Neisseria gonorrhoeae resistant to multiple antibiotics has attracted special attention in our country. Syphilis has many ocular manifestations such as keratitis, iridocyclitis, retinochorioiditis, and neuritis, etc. Ocular complications related to HIV infection, including HIV retinopathy, cytomegalovirus retinitis, zoster ophthalmics, and Kaposi s sarcoma in conjunctiva are increasing in Japan. Phthirus pubis infection of the eye lid, and human T-cell lymphotropic virus type 1 (HTLV-1)-associated uveitis are occasionally reported. Furthermore conjunctival tumor associated with human papilloma virus (HPV) infection, acute retinal necrosis(ARN) due to herpes simplex virus type 2 (HSV-2), as well as hepatitis B virus (HVB) and hepatitis C virus (HVC) retinopathy are also mentioned in this review.

We present a case of early detected Acanthamoeba keratitis. The patient was a 31 year-old female with keratitis who was referred to our clinic. Upon arrival the patient presented with subepithelial corneal infiltrates and radiating neuritis. In vivo confocal microscopy showed Acanthamoeba cysts and treatment was initiated. Polymerase chain reaction analysis later confirmed the diagnosis and after three months symptoms had abated and vision was 1.0 (6/6). We confirm that an early diagnosis af Acanthamoeba keratitis is pivotal.

The eyes diseases appear at any stage of Lyme borreliosis and clinical manifestations are polymorphic and non-specific. The study examined prevalence of B. burgdorferi s.l. infection in patients with different eyes diseases and evaluated diagnostic significance of antibodies to B. burgdorferi in clinical practice. The sampling included 57 patients with conjunctivitis, keratitis, uveitis, choreoretinitis, optical neuritis of unclear etiology. The blood serum of patients was analyzed to detect presence of IgM- and IgG-antibodies to B. burgdorferi s.l. The positive results were confirmed in Western blot (two-sweep method). The immune enzyme analysis detected antibodies to B. burgdorferi in 7 out of 57 examined patients (12.3%). The Western blot confirmed presence of antibodies only in 3 serums out of 57 (5.3%). The high rate of false positive results was established during immune enzyme analysis detecting IgM-antibodies to B. burgdorferi. On the basis of comprehensive examination ophtalmo-borreliosis was diagnosed in two out of three patients seropositive to B. burgdorferi. In one seropositive patient co-infection B. burgdorferi provoked exacerbation of chronic uveitis of unclear etiology. It is appropriate to include in plan of examination of patients with inflammatory eyes diseases of unclear genesis the detection of antibodies to B. burgdorferi using two-sweep test (study of serums with immune enzyme analysis, confirmation of positive results in Western blot).
