The continued study of immunology and its relationship to diseases of the eye will hopefully give some insight into the pathogenic mechanisms of certain ocular diseases of many species, including the horse. It may lead to a better understanding of equine recurrent uveitis, a disease that has remained an enigma for years and that now appears to be an immunologic hypersensitivity response to a number of varied antigens. The precise mechanism of the inflammation is still unclear, and the immunologic response may be variable or mixed depending upon the inciting antigen. Other ophthalmic diseases in the horse, such as conjunctivitis, chorioretinitis, and less well-defined entities such as superficial punctate keratitis, may also have an immunologic component in their pathogenesis. An appreciation of immunopathologic mechanisms may thus enhance the veterinarian's understanding of the pathophysiology and treatment of equine ocular disease.

A clinical examination of 199 leprosy patients in Kenya showed that 62.5% had abnormal ocular findings, 51.2% of which were leprosy related. The potentially blinding lesions were uveitis, keratitis and lagophthalmos and these were found in 22.1% of the patients. 6 Patients (3%) had a visual acuity of less than 3/60 in the better eye and were classified blind. In all, there were 31 blind eyes of which only 12 had leprosy related causes. 10 of these (83%) belonged to lepromatous patients and 2 (17%) to tuberculoid patients. All the 10 eyes of the lepromatous patients were blind due to uveitis. It was shown that lepromatous leprosy patients are at a greater risk of leprosy related blindness especially from uveitis. The socio-psychological and economic implications of leprosy are discussed. Practical recommendations for the primary eye care of the leprosy patient are suggested.

Thirty consecutive patients with biopsy-proved mycosis fungoides were examined ophthalmologically. Specific ocular changes, judged directly related to the mycosis fungoides, were found in 11 of the 30 subjects, usually in the late plaque or tumor stages of the disease. Tumors, especially involving the lids, were the most common ophthalmic finding. Keratitis, uveitis, and optic atrophy were also described. A review of the literature is given, and changes found in patients in this series correlate well with ophthalmic findings presented in diverse isolated case reports. It seems that the frequency of ophthalmic pathologic findings in mycosis fungoides is much more common than previously assumed.

Eye diseases in 1028 children below 15 years of age, seen at the Eye clinic of the University College Hospital, Ibadan, Nigeria were studied. Refractive error, vernal conjunctivitis, measles keratitis associated with malnutrition and those referrable to injuries were leading causes of eye problems amongst children. Diseases of ocular adnexa (excluding orbital cellulitis) squints, glaucoma, uveitis and trachoma were rare.

Necrobiotic xanthogranuloma is a rare disease marked by yellowish-brown plaques with destructive growth and a tendency to ulceration, which shows a characteristic histopathological pattern of palisading granuloma with foam cells, Touton's and foreign-body giant cells, bizarre multinuclear giant cells, cholesterol clefts and marked necrobiosis of the connective tissue. Necrobiotic xanthogranuloma is associated with IgG paraproteinaemia, and occasionally with an IgA paraproteinaemia. Ocular symptoms and visceral involvement are common. We report a case of a 53-year-old woman with periorbital necrobiotic xanthogranuloma, ocular involvement and IgG paraproteinaemia, who had undergone argon-laser treatment to no avail following a diagnosis of xanthelasma. Periorbital xanthelasma-like lesions with a tendency to ulceration in combination with unexplained ocular symptoms consisting of keratitis, scleritis, episcleritis or uveitis should suggest the diagnosis of necrobiotic xanthogranuloma, especially if they are associated with paraproteinaemia.

Pathomorphosis of tuberculous uveitis and keratitis was investigated as regards present-day clinical presentation and literature data on prebacterial period. There was chronic productive inflammation, exudative inflammation and mixed tuberculous infection. Pathomorphosis was evident from a sharp diminution of uveitis and keratitis incidence and severity at young age, in more apparent exudative response, polymorphism of clinical symptoms and more frequent recurrences.

Although ocular manifestations of Lyme disease have long been noted, they remain a rare feature of the disease. The spirochete invades the eye early and remains dormant, accounting for both early and late ocular manifestations. A nonspecific follicular conjunctivitis occurs in approximately 10% of patients with early Lyme disease. Keratitis occurs often within a few months of onset of disease and is characterized by nummular nonstaining opacities. Inflammatory syndromes, such as vitritis and uveitis, have been reported; in some cases, a vitreous tap is required for diagnosis. Neuro-ophthalmic manifestations include neuroretinitis, involvement of multiple cranial nerves, optic atrophy, and disc edema. Seventh nerve paresis can lead to neurotrophic keratitis. In endemic areas, Lyme disease may be responsible for approximately 25% of new-onset Bell's palsy. Criteria for establishing that eye findings can be attributed to Lyme disease include the lack of evidence of other disease, other clinical findings consistent with Lyme disease, occurrence in patients living in an endemic area, positive serology, and, in most cases, response to treatment. Management of ocular manifestations often requires intravenous therapy.

Hepatocyte derived C-reactive protein (CRP) is a sensitive indicator for inflammatory or infectious processes in a variety of tissues. As several other plasma proteins it is regarded as part of the acute phase response to a variety of tissue damage. CRP is commonly used in general medicine as a tool for the follow-up of especially bacterial infections. However, it has not been widely used in ophthalmology. In the present study CRP values in serum samples from 51 patients with various acute ocular diseases were determined semiquantitatively. High CRP levels were found most frequently in patients with either preseptal cellulitis (83.3%) or endophthalmitis (25.8%) whereas in the serum of patients with keratitis and uveitis, CRP exceeded 20 mg/l in only 18.7% of the cases. In a control group of 10 patients with retinal detachment the mean CRP level was 2.3 mg/l (SD +/- 0.98 mg/ml). The clinical significance and the prognostic value of CRP determinations during ocular diseases are discussed.

It is well known that polyarticular joint diseases such as rheumatoid arthritis, HLA-B27-associated arthritis and Borreliosis can be associated with eye diseases, such as uveitis, scleritis and keratitis. However, the mechanisms underlying the involvement of these tissues remain unclear. A recent meeting examined the immunoregulation of the eye and the joint in an attempt to determine their similarities and differences.

Treatment of central nonexudative chorioretinal dystrophies, vascular opticopathies, keratitis and uveitis associated with disorders of immunity status is a pressing problem of ophthalmology. Intravascular laser exposure of the blood was used for the treatment of these conditions. ALOK-1 device for low-energy He-Ne intravenous irradiation of the blood was used. The authors analyze the results attained in 15 patients (24 eyes) with central nonexudative chorioretinal dystrophies and vascular opticopathies (group 1) and in 16 ones (20 eyes) with chronic relapsing keratitis and uveitis (group 2). A positive effect was attained in all the cases, manifesting in group 1 in improvement of vision acuity, widening of visual field, normalization of electrophysiological parameters and in group 2 in improvement of vision acuity, rapid resorption of corneal precipitate, reduced injection of the eyeball and opacities in the vitreous body, a more rapid corneal epithelialization, and normalization of blood and lacrimal immunograms. The attained effect may be explained by a complex neurotrophic and immunomodulating effect of laser. The method is sufficiently effective and simple, this permitting its use on an outpatient basis.
