Loss of central visual acuity is disturbing to the patient and to the ophthalmologist. Disturbance of the central vision may be associated with central choroiditis or with retinitis. It is commonly a progressive disease which fails to respond to any specific therapy, and the result is a central scotoma. The ophthalmologist frequently makes desperate efforts to treat the lesion either as choroiditis or as a vascular disease of the retina.There have been many descriptive terms applied to these central lesions, and occasionally these central lesions are very characteristic. Toxoplasmosis of the retina and choroid is now a recognized clinical entity which can be supported by laboratory and x-ray findings (Fig. la.). Since these lesions in the macula are almost always progressive and result in considerable visual disturbance, early clinical and laboratory diagnosis and prompt treatment may result in some saving of vision.
