Abstract
We appreciate the comments expressed by Dr. Joseph Schmitz regarding our manuscript about subconjunctival hemorrhage (SCH) and conjunctivochalasis (CCh) published in the October 2009 issue.1Mimura T. Usui T. Yamagami S. et al.Subconjunctival hemorrhage and conjunctivochalasis.Ophthalmology. 2009; 116: 1880-1886Abstract Full Text Full Text PDF PubMed Scopus (25) Google ScholarI agree with Dr. Schmitz in thinking that further studies are needed to determine the relationship between between CCh and SCH using another control group with hypertension, hyperlipidemia or diabetes as we discussed in the manuscript. We have noted that the prevalence of hypertension, hyperlipidemia, and diabetes was higher in our SCH patients than in the controls in the discussion section as a study limitation. Persons with these systemic vascular diseases have an increased risk of macrovascular diseases such as SCH, as well as an age-related increase of CCh. The comments of Dr. Schmitz are helpful.

Conjunctivochalasis and Subconjunctival HemorrhageOphthalmologyVol. 117Issue 12PreviewI read with interest the article “Subconjunctival Hemorrhage and Conjunctivochalasis” by Mimura et al.1 They conclude that conjunctivochalasis (CCh) may have a strong role in the pathogenesis of subconjunctival hemorrhage (SCH) based on the more severe CCh found in subjects with SCH versus the control group. I believe that the control group, as described in the subjects and methods section, was inappropriate for this study. Specifically, as the authors acknowledge in the introduction, SCH is known to be associated with systemic disorders such as diabetes, hypertension, and arteriosclerosis. Full-Text PDF
