Phacodonesis (; from Ancient Greek  φακός (phakos) lens, and  δονέω (doneo) to shake) is the tremulousness or vibration of the lens with eye movement. This is often due to lens subluxation, the incomplete or partial dislocation of the lens, caused by an injury to the eye in which some or most of the zonular fibers are broken. See also

This is because children from countries of high incidence of tuberculosis can contract the lesion after contact with tuberculous sputum, by walking barefoot, sitting or playing on the ground.When recent, the skin lesion has the outside appearance of a wart or verruca, thus it can be confused with other kinds of warts. It evolves to an annular red-brown plaque with time, with central healing and gradual expansion in the periphery. In this phase, it can be confused with fungal infections such as blastomycosis and chromoblastomycosis. Cause
Diagnosis
The diagnosis is confirmed by a skin biopsy and a positive culture for acid-fast bacilli. A PPD test may also result positive. Treatment
Therapy for cutaneous tuberculosis is the same as for systemic tuberculosis, and usually consists of a 4-drug regimen, i.e., isoniazid, rifampin, pyrazinamide, and ethambutol or streptomycin. See also
