Purpose To design and validate a standard, simple, and reliable iris color classification and to study its distribution in a Spanish population. Iris color has a geographic distribution and has been correlated with different ocular diseases. However, there is no standard and validated iris color classification allowing comparison among different studies. Methods Classification was made in three grades (blue-gray, hazel-green, brown) and was validated by 3 independent readers. Initially, a preliminary study was made in 50 iris photographs to detect technical hitches. Afterwards, based on this procedure, 221 iris photographs were graded Results Measures of interobserver reliability were 0.786 by kappa index with an agreement of 89.6%. Iris color distribution in the Spanish cohort was blue-grey 16.29%, hazel-green 55.2%, and brown 28.5%. Conclusions This classification is simple, reliable, and easy to use in clinical research and by ophthalmologists or generalists in practice. The Spanish cohort from this study shows a different iris color distribution from those previously published in other countries.
Ciliary body melanocytoma is a rare benign pigmented tumor that may present extension to the anterior chamber. Differential diagnosis mainly includes ciliary body melanoma, which carries a different prognosis and treatment.
RESUMO
ABSTRACTWe present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fungal colonization formation may be the first event before dacryocystitis and should be considered as a cause of epiphora.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
