The clinical picture of HIV-associated eye disease has changed dramatically since the introduction of highly active antiretroviral chemotherapy (HAART). As a consequence of the marked reconstitution of immune function and the control of retroviral replication, thereby effected, the clinical manifestations of infectious eye disease are not so patent. Although direct infectious destruction of tissue is less severe, inflammatory infiltration is augmented, and this gives rise to a situation that is open to misinterpretation. Furthermore, several completely new disease entities have been described. One of these is the so-called immune-recovery uveitis, which involves mainly the anterior uvea and vitreous, and is not uncommonly associated with a marked disturbance of visual function. Another group of new diseases has been attributed to the toxic effects of drugs, i.e. of Cidofovir and Rifabutin. In both instances, a principally anterior form of uveitis develops, which is characterized by a discrepancy between clinical symptoms and morphological changes; the former condition is distinguished by severe pain, and the latter by marked inflammation. This article describes the clinical pictures characterizing these new affections of the anterior segment, postulates on the possible causes of the seemingly paradoxical clinical, morphological and immunological situations sometimes presented by them, and comments on recommended treatment strategies. The information furnished is designed to help the clinical practitioner in making his/her diagnostic and therapeutic decisions.

Ocular emergencies can be very intimidating for veterinarians. Most ocular emergencies can be stabilized by the veterinarian until an ophthalmologist can be consulted if necessary. Proptosis, or forward displacement of the globe, can occur secondary to any blunt trauma to the head. The two options for a proptosed eye are enucleation or replacement with tarsorrhaphy depending on the viability of the extraocular tissues and eye. Glaucoma, or increased intraocular pressure (above 35 mm Hg), is diagnosed by measuring the intraocular pressure using a Shiotz or electronic tonometer. Emergency treatment includes intravenous mannitol and topical pilocarpine. Uveitis, or inflammation of the iris, ciliary body and/or choroid, can have many underlying causes such as neoplasia, infection, lens induced, and trauma. The treatment consists of treating the underlying cause, and administering topical atropine to alleviate pain and topical corticosteroids to decrease inflammation. Corneal ulcers, or defects in the corneal epithelium, are classified according to the depth of the defect. The treatment consists of topical antibiotics and topical atropine. If the ulcer is deep, is melting, or is a descemetocele, then a third eyelid or conjunctival flap is usually necessary. The cornea should be sutured if it is perforated or lacerated. Hyphema, or blood in the anterior chamber, can occur secondary to trauma, neoplasia, infection, or a coagulapathy. The treatment consists of treating the underlying cause and topical corticosteroids with or without antibiotics.

A case of keratitis due to caterpillar hairs of the Pseudosphinx tetrio is reported. As he was clearing his garden without glasses or a protective headgear, the patient felt left ocular pain due to the projection of a caterpillar into the eye. On examination, there were numerous intrastromal caterpillar hairs involving the inferior temporal quadrant of the cornea. The small size of the hairs prevented removal with forceps. The patient was treated by extensive washing of the eyeball and topical application of anti-inflammatory drugs, cycloplegics and antibiotics. The caterpillar hairs gradually came off the cornea over a two-weeks period. The cornea remained free of any scar. Besides keratitis and conjunctivitis, caterpillar hairs are known to cause iris nodules, chronic uveitis, cataract, hyalitis, chorioretinitis, and orbital cellulitis.

Spondylarthropathies consist of several disorders: reactive arthritis, psoriatic arthritis, arthritis associated with inflammatory bowel disease, a subgroup of juvenile chronic arthritis, and ankylosing spondylitis. Their clinical presentation may consist in the following inter-related features: axial involvement, peripheral articular involvement, enthesiopathic lesions, extra-articular disease. The monitoring of these diseases is related more to their clinical presentation than to the precise diagnosis. Modalities for monitoring peripheral arthritis are similar to those of rheumatoid arthritis (essentially based on the number of tender and swollen joints). The modalities of the monitoring of extra-articular features (uveitis, psoriasis,...) are specific to these clinical features and can be categorized in 2 ways: the first one consists in considering the occurrence of the episodes (for example, number of acute anterior uveitis per year), the second one consists in the evaluation of the severity of the clinical features (for example the area of psoriatic skin lesions). Numerous tools have been proposed to evaluate the axial involvement of the disease. The international rheumatologic community (ILAR for International League Against Rheumatism) via specific task force (ASAS for Assessment in Ankylosing Spondylitis) tried to standardize the medical language (at least in clinical research studies) by giving recommendations to evaluate specific domains and within each domain specific tools. Currently, it is generally agreed that pain and functional impairment are the two main domains to consider. For each of these domains, different tools have been proposed (for example the ASFI: Ankylosing Spondylitis Functional Index and the BASFI: Bath Ankylosing Functional Index are both tools proposed to evaluate the functional impairment). The domain "range of motion" is probably one of the most important for long term outcome in clinical research studies and for facilitating the orthopedic indications in daily practice. Finally, radiological tools permitting the evaluation of the structural damage of the disease are available. They take into account the presence and/or the severity of hip and sacroiliac involvement and also the extent of the spinal syndesmophytes. Longitudinal studies are required to evaluate their clinical relevance.

(1) Pamidronic acid, a diphosphonate, is now approved for intravenous treatment of Paget's disease in France. Treatment is given over two to three days, in hospital, and can be repeated six months later. (2) The clinical file contains only non comparative trial data suggesting that a total dose of 180-210 mg has a clinical benefit in most patients and tends to normalise biochemical criteria thought to reflect disease progression. (3) Because no comparative trials have been done, there is no way of knowing whether a short course of intravenous pamidronic acid is any more or less effective that long-term oral etidronic acid or tiludronic acid therapy. However, in the non comparative trials a number of patients who had become resistant to oral diphosphonate therapy had a clinical and/or biochemical response to intravenous pamidronic acid. (4) While intravenous pamidronic acid is well tolerated overall, the precise incidence of its adverse effects on bone (transient increase in pain, osteomalacia) and the eyes (uveitis) is not known.

Undifferentiated spondylarthropathy is one of the common disease subsets in the group of so-called seronegative spondarthritides. It is not exactly known how often it differentiates into ankylosing spondylitis or other well-defined disease subsets over time. The present study was designed to find out the long-term outcome in this subset. Thirty-five patients diagnosed with undifferentiated spondylarthropathy between January 1987 and December 1988 were recruited. Twenty-two (63%) of them were available for detailed assessment 11 years after the original diagnosis. Their baseline characteristics did not differ from those of the original cohort of 35 patients and were as follows: male:female ratio 19:3, median age of onset 17 years (range 8-39), and median duration of disease 8 months (range 4-24). Clinical features were enthesitis (45%) and inflammatory pain in the back (100%), buttock (77%), hip (64%), shoulder (18%), knee (82%), ankle (77%), and hand and wrists (50%). There was no restriction in spinal movement. Family history was positive in two cases. Radiologically, the only finding was grade I sacroiliitis in 17 patients (77%). Human leukocyte antigen (HLA)-B27 was positive in all. Functionally, all were in class I. During follow-up, one patient developed psoriatic skin lesions after 9 years. Uveitis developed in four patients (18%). After a median follow-up of 11 years, 15 (68%) had ankylosing spondylitis, one developed psoriatic arthritis, four remained undifferentiated, and two had natural remission. Functionally, 19 patients (86%) were in class I and three (14%) were in class III. No patient had bamboo spine, but three underwent total hip replacement. Thus, a majority of patients (68%) with undifferentiated spondylarthropathy gradually developed ankylosing spondylitis of mild severity.

A CLINICAL ASPECT DEPENDING ON THE PHYSIOPATHOGENESIS: Ocular infections are a frequent motive for ophthalmological consultations in geriatric settings because of the mechanical factors related to age (modifications in palpebral dynamics and lacrymal function) and in local and general immune factors leading to the rapid and/or more severe development of infections. The mechanism of microbial contamination of the eye also determines the clinical damage: predominantly local (dirty hands, traumas) with involvement of the surface tissues (conjunctive and cornea) or general, hematogenic or neurogenic, frequently at the origin of more internal infections (iris, choroid, retina, optical nerve). CONJUNCTIVITIS AND KERATITIS: These provoke reddening of the eyes, tears and above all pain when the corneal epithelium is involved. Microbiological samples are useful in cases of severe, presumably infectious keratitis or conjunctivitis. Two emergency situations must be distinguished: any suspicion of herpes for which local corticosteroids are contraindicated and keratitis or conjunctivitis with the use of lenses, often due to Gram negative bacilli, amoeba or fungus, the treatment of which is intensive and the prognosis often severe. OPHTHALMOLOGICAL HERPES ZOSTER: The rapid diagnosis and introduction of efficient doses of antivirals reduces the initial pain, the ocular complications of herpes zoster and post-zoster pain. The latter, when it exists, requires specialized management. ACUTE UVEITIS: A context of intra-ocular inflammation in an elderly patient must always evoke a pseudo-uveitis syndrome, the principle cause of which is lymphoma. Conversely, an uveitis occurring in the days or weeks following ocular surgery, including cataract, must be considered as suggestive of a post-surgical infection and rapidly referred to a specialist. ACUTE DACRYOCYSTITIS: Is manifested by a hard and painful tumefaction below the internal angle of the eye. Following collection, it requires draining through an in incision in the skin, washing and packing of the sac, and systemic antibiotherapy. The preventive treatment of recurrences requires open dacryocystorhinostomy or via endonasal endoscopy.

Erythema Multiforme (EM) is a rare mucocutaneous disease with a variety of clinical manifestations. EM it was recognized in the early 1800's, and still the etiology is unknown. It has been recently suggested erythema multiforme (EM) major and Stevens-Johnson Syndrome (SJS) could be separated as two distinct clinical disorders with similar mucosal erosions, but different patterns of cutaneous lesions. In particular SJS should be used for a syndrome characterized by mucous membrane erosions and widespread small blisters that appear on erythematous or purpuric maculae, which are different from classic targets. In SJS mouth, eyes, skin, genitalia and occasionally the esophagus and respiratory track may be affected. Oral lesions may cause severe pain and usually lips may become encrusted. Concerning ocular involvement, if there is conjunctivitis or uveitis this may lead to scarring and blindness. Also, the course of disease and the prognosis are in most cases severe.

Herpes zoster ophthalmicus occurs when the varicella-zoster virus is reactivated in the ophthalmic division of the trigeminal nerve. Herpes zoster ophthalmicus represents up to one fourth of all cases of herpes zoster. Most patients with herpes zoster ophthalmicus present with a periorbital vesicular rash distributed according to the affected dermatome. A minority of patients may also develop conjunctivitis, keratitis, uveitis, and ocular cranial-nerve palsies. Permanent sequelae of ophthalmic zoster infection may include chronic ocular inflammation, loss of vision, and debilitating pain. Antiviral medications such as acyclovir, valacyclovir, and famcidovir remain the mainstay of therapy and are most effective in preventing ocular involvement when begun within 72 hours after the onset of the rash. Timely diagnosis and management of herpes zoster ophthalmicus. with referral to an ophthalmologist when ophthalmic involvement is present, are critical in limiting visual morbidity.

Because of the wide variety of x-rays now available, selectivity is possible and important in treatment of diseases of the eye. By the use of short-range radiation, newly developed eye shields and the insulation of the eyelid itself, and by careful angulation of the beam, the desired irradiation can be given where it is needed without injury to surrounding tissues. The authors have found the 50 kv x-ray unit to be the most reliable and adaptable for most circumstances. The skin of the eyelid reacts to irradiation more sensitively than other tissues. The cornea reacts with keratitis and sometimes intractable ulceration. The iris, uveal tract and retina are less seriously affected. At the University of California Hospital irradiation has been found satisfactory for treatment of corneal ulcer, keratitis, pterygium, certain types of conjunctivitis, episcleritis, corneal vascularization, iritis, uveitis, and hemangioma. Irradiation may be of great benefit in absolute glaucoma with pain and blindness. Of 42 patients with carcinoma of the eyelid treated between 1935 and 1946, 27 had no recurrence in five years, 5 had recurrence, 7 died of other causes and follow-up was incomplete on 3. Good cosmetic result was usually achieved. No recurrence has been observed in 22 patients treated since 1946. Irradiation has been used with success in other kinds of cancer of the eye structures.
