A case of sympathetic ophthalmitis is reported. A bull's eye chorioretinopathy was observed with electroretinographic changes (augmentation of latencies and disappearance of oscillatory potentials) which regressed in a short time. The authors believe that the retinal changes could be secondary to an autoimmunological reaction, responsible for the sympathetic ophthalmitis.
A case of sympathetic uveitis which developed after several operations to reduce intraocular pressure is reported. Initially there was a thrombosis of the central vein; secondary glaucoma developed after laser coagulation and iridectomy; six operations followed. Some months later the diagnosis of sympathetic uveitis was established. The pathogenesis of sympathetic uveitis in this case is discussed.

In a prospective 2-month case-controlled study, 17 cases of neonatal conjunctivitis were diagnosed. A statistically significant association between neonatal conjunctivitis and the presence of Chlamydia trachomatis (five cases) and Staphylococcus aureus (five cases) was shown. No cases of gonococcal conjunctivitis were found, perhaps because of the routine use of silver nitrate (1%) drops. C. trachomatis conjunctivitis could not be diagnosed on clinical grounds, nor was examination of Giemsa-stained conjunctival scrapes sufficiently sensitive to detect all cases. In order to prevent the long-term morbidity of C. trachomatis infection in both mother and child, specific aetiological diagnosis using immunodiagnostic or cultural procedures is required.
A culture from conjunctivitis occurring in a neonate in association with a recurrent fever yielded a nearly pure growth of Branhamella (Neisseria) catarrhalis. The conjunctivitis was not appreciated and effectively treated until a second hospitalization in the fourth week of life. Partial suppression of symptoms had followed short-term parenteral antibiotic therapy during the first admission. Resolution quickly occurred in response to instillation of sodium sulfacetamide ophthalmic solution. Although B. catarrhalis is considered a non-pathogen, the literature reviewed included a number of diverse infections, but no previous instance of conjunctivitis. The organism's close similarities to Neisseria gonorrhoeae necessitate isolation and correct biochemical differentiation. Misdiagnosis of gonococcal conjunctivitis carries obvious social, psychological and medical impact.

Although uncommon, SO is a fearful postoperative complication because of its potential to blind both eyes. It can result not only from penetrating ocular surgery but also from nonpenetrating ocular procedures. Thus, it is important to consider in any patient who has undergone ocular surgery and develops bilateral uveitis, particularly because prompt, sufficient treatment is required to maximize visual outcome. It is also important to note that the disease may present with a spectrum of clinical findings, none of which is pathognomonic. Thus, suspicion is important for making the diagnosis. Treatment should address the T-cell-mediated nature of the disease. With appropriate treatment, visual acuity of no less than 20/60 is likely. However, before the start of treatment, which consists of immunosuppressants, infection must be ruled out and potential side effects of treatments must be considered. Furthermore, any patient with a history of SO needs ample immunosuppressant coverage for ocular procedures. Better understanding of the pathogenesis of the disease may lead to safer treatments that result in improved visual outcome and a cure. Meanwhile, because of its relapsing nature, SO requires continual, close surveillance, even after many years of quiescence.
