RESUMEN
BACKGROUND: Although non-diphtherial corynebacteria are ubiquitous in nature and commonly colonise the skin and mucous membranes of humans, they rarely account for clinical infection. METHODS AND RESULTS: 10 patients with unilateral conjunctivitis are described in which Corynebacterium macginleyi was isolated. This species has only recently been reported to be exclusively isolated form ocular surfaces. C macginleyi was uniformly susceptible to topical antibiotics commonly used in ophthalmology. CONCLUSION: Despite the fact that the pathogenicity of C macginleyi is not yet assured, this micro-organism should be recognised as a potential cause of bacterial superinfections. Appropriate antibiotic therapy leads to its elimination and resolution of the conjunctivitis.

71 eyes with Coats' disease were treated with photocoagulation. By coagulation of the abnormal vessels the disease process could be halted in 64 eyes over a mean observation time of 2 years and 3 months after completion of treatment. In 51 of these eyes the lipoid deposits regressed. In only 7 eyes a progression of the disease could not be prevented. Complications of photocoagulation treatment were not observed.

In a 43-year-old female patient with sclerodermie en coup de sabre on the right forehead, the following changes of the right eye were observed: Partial lack of hairs of the eyebrow; distortion of the upper eyelid, similar to a coloboma; paralysis of the inferior oblique and the superior rectus muscles; decrease of corneal sensibility; formation of a spontaneous filtering bleb in the upper limbal region; ocular hypotension with changes of the papilla.

Coats' disease represents a disorder of the retinal vascular walls. In a series of 112 consecutive eyes with Coats' disease the involvement was unilateral in 90.2%. The majority (72%) of patients were male. 57.8% were under 20 years of age. There was, however, a second peak of the disease (30.4%) between the age of 41 and 60. Severe cases were found mainly among juvenile patients, whereas in the senile group milder cases prevailed. Fluorescein angiographic findings comprised vascular aneurysms in almost all cases, rarefaction and coarsening of the capillary bed in 71%, capillary occlusions in 70%, occlusions of arterioles or arteries in 27%, shunt formations in 27%, extensive widening of arteries or veins in 27% and leakage of dye mainly in advanced cases. The participation of the central retina in the disease process was variable. Evidence is presented that Leber's military aneurysm retinitis is not a separate entity but a special form of Coats' disease.
