A unique form of dichromatic color vision is described in a family with incomplete achromatopsia. In 1966, incomplete achromatopsia was diagnosed in 4 of 14 children of a consanguineous marriage. The 4 affected had best visual acuities of 6/60 or 6/180, pendular nystagmus, and aversion to bright lights. The ERG showed minimal photopic responses. No abnormality of rod function was present. There was a severe color vision defect. In 1976, one of the patients returned for further color testing. Color tests included measurement of the luminous efficiency function using heterochromatic flicker photometry and colorimetric evaluation. The luminous efficiency function resembled that of the protanope. From the colorimetric measurements, we conclude that the patient has a unique form of dichromatic color vision mediated by two visual photopigments: the normal MWS cone photopigment and a photopigment with the spectral characteristics of rhodopsin.

Purpose: To present the ocular findings of the members of a family that has the diagnosis of Muckle Wells syndrome, a form of cryopyrin associated periodic syndrome (CAPS).Materials and Methods: Nine patients with MWS were included in this study. Each study participant underwent a systemic evaluation, comprehensive ophthalmic examination, and auxillary testings.Results: In this study, conjunctivitis was the most prominent ocular finding. Other relatively common ocular findings included band keratopathy, clinical signs of past uveitis, and corneal topography abnormalities. Nystagmus, corneal leukoma, and optic nerve pallor with epiretinal membrane were also detected. Rare ocular manifestations were posterior stromal corneal opacification with edema, anterior iris snychecia, and mild cataract.Conclusion: MWS is a rare systemic autoinflammatory disorder that presents with a variety of ocular findings. Exacerbation of systemic and ocular findings with cold is a hallmark of the disease.
