A doctor's personal credibility is the paramount factor in achieving success when testifying, especially as a defendant. Factors that aid credibility include a natural manner, sincerity, confidence, clarity and composure. Being argumentative, defensive, smug, flamboyant, or nervous undermines credibility. The authors offer advice to enhance the ophthalmologist's success in testifying.

Biography Historical ArticleDegas' loss of vision: evidence for a diagnosis of retinal disease.
The Impressionist artist Degas suffered severely from loss of vision. He described this many times in his letters. His correspondence and his notebooks mention three ophthalmologists. Degas' words and those of acquaintances, as well as his artistic works, reveal important information about his vision, which allows us to draw conclusions about the cause of his problem.

Case ReportsOrbitocranial wooden foreign body diagnosed by magnetic resonance imaging. Dry wood can be isodense with air and orbital fat by computed tomography.
In computed tomographic (CT) scans, a wooden foreign body can appear as a lucency with nearly the same density as air or fat, and it can be indistinguishable from orbital adipose tissue. Magnetic resonance imaging (MRI) can localize these wooden foreign bodies in the orbit. We studied a case in which a wooden golf tee lodged in the right optic canal of a nine-year-old boy. ⋯ However, the golf tee was demonstrated by MRI as a low intensity image. Although it was removed by craniotomy with good neurological results, bacterial panophthalmitis led to enucleation of the eye. This case emphasizes the diagnostic value of MRI and the hazards of retained wooden foreign bodies.

Review Case ReportsElectrophysiological and psychophysical testing of vision in glaucoma.
Electrophysiological testing in patients with early glaucoma and in glaucoma suspects reveals defects of central or foveal vision. Most studies suggest that glaucomatous eyes are best separated from normal eyes by use of stimuli with a spatial frequency below the peak of the human contrast sensitivity curve and a relatively high temporal frequency. The stimulus-dependent abnormalities in glaucoma are generally consistent with contrast sensitivity data The stimulus-dependent visual changes are related to the physiology of parallel processing in the primate retinogeniculate pathway.

An 81-year-old-woman developed a right facial palsy and orbital cellulitis following an apparently innocuous puncture injury of the right lower eyelid. Generalized tetanus ensued which proved fatal despite aggressive treatment including use of tetanus immune globulin, wound debridement, and neuromuscular blockade with ventilatory assistance. Tetanus immunization status should be ascertained in all patients with potentially contaminated wounds in and around the eye. Cephalic tetanus, may be misleading initially because of the presence of cranial nerve palsies and the absence of classic signs such as trismus and risus sardonicus.
