ABSTRACT
OBJECTIVE:
Subconjunctival hemorrhage (SCH) is a relatively common disease, but there have been no reports concerning the relationship between SCH and conjunctivochalasis (CCh). We compared the grade of CCh between patients with SCH and control patients.DESIGN:
Prospective, nonrandomized study.PARTICIPANTS:
A total of 104 patients with SCH aged 41 to 94 years and 120 age- and gender-matched controls aged 41 to 94 years were enrolled.METHODS:
The conjunctiva was divided into the following 8 equal areas superior, superior/nasal, nasal, inferior/nasal, inferior, inferior/temporal, temporal, and superior/temporal. The age, gender, medical history, ocular history, site of hemorrhage, grade of CCh at 3 locations (nasal, middle, and temporal), and other parameters of CCh were determined in all subjects. MAIN OUTCOMEMEASURES:
Grade of each CCh parameter and location of SCH.RESULTS:
The mean grade of CCh was higher in patients with SCH than in control patients at the nasal (P<0.00001), middle (P<0.00001), and temporal areas (P<0.00001). The downward gaze- or digital pressure-dependent changes of CCh and the frequency of superficial punctate keratitis were all increased in SCH patients compared with control patients (P<0.00001, P<0.00001, and P = 0.00106, respectively). The number of areas involved by SCH and the presence of SCH in each area were positively correlated with the grade of each CCh-related parameter (P<0.05).CONCLUSIONS:
This was the first assessment of the grade of CCh in a large series of consecutive patients with SCH. Our results strongly suggest that CCh may have an important role in the pathogenesis of SCH.
