Retinal manifestations of Mediterranean spotted fever.
The authors studied the incidence, type and systemic relationship of the retinal findings observed by ophthalmoscopy in Mediterranean spotted fever (MSF) in a consecutive series of 34 cases. It is found that retinal vasculitis either arterial and/or, more frequently, venous is present in 55.9% of the cases. Branch vein retinal thrombosis appeared as complication of such small vessel vasculitis in 1 case. Although frequent, the retinal findings were asymptomatic in all cases but the retinal vein thrombosis one, and were not significatively related to or were predicted by other systemic parameters of severity of the disease. Because of its frequency, retinal vasculitis might be considered as an important clinical sign of MSF in endemic areas.

Rickettsial keratitis in a case of Mediterranean spotted fever.
The first documented case of infectious keratitis (an ameboid-like corneal ulcer) caused by Rickettsia conorii is described. Corneal infection was probably caused by contamination through the tears during systemic rickettsial dissemination. Topical tetracyclin ointment was effective. Rickettsial keratitis should be considered in the differential diagnosis of ameboid-like corneal ulcers in areas where Mediterranean spotted fever is endemic.
