• Macula

  […] agents may be required for ocular disease: topical antibiotics for conjunctivitis or keratitis, topical steroids and mydriatic drops for anterior uveitis, systemic steroids for severe ophthalmic involvement, such as extensive retinitis threatening the macula [omicsonline.org]

  Initially rash is in the form of pink, blanching, discrete maculae which subsequently becomes maculopapular, petechial or haemorrhagic [24]. None of these clinical symptoms and signs including eschar are diagnostic of rickettsial disease. [ijmr.org.in]
