Purpose: Subconjunctival hemorrhage (SCH) is a relatively common disease which is characterized by an acute onset of bleeding under the bulbar conjunctiva. However, the etiology and the cause are not defined. We have investigated the age, gender, incidence, seasonal occurrence, location, extent, and medical history for patients with SCH.

Methods: The study was designed as prospective from April 2011 to March 2013. A total number of the outpatients was 69058 in the study. A total of 743 patients with SCH aged 1-91 years was enrolled. There were 286 men and 457 women. The average age was 57.9 ± 20.4 years old. The excluding criteria was SCH associated with ocular injections and/or ocular surgeries. The age, gender, incidence, seasonal occurrence, location, extent and medical history of the patients were determined. <br />

Results: The incidence of SCH outpatients was 1.1%(743/69058). SCH was more common in female, and the male to female ratio of SCH was 2:3. SCH was found on the right eye in 355 patients, on the left eye in 388 patients and on the both eyes in 9 patients. Seasonal variation was not statistically significant. The incidence of SCH showed an increase with age. The peak onset of SCH was between 71 and 80 years. The extent of SCH was more commonly seen within one quadrant around corneal limbs(58.5%). About 23.5% of eyes had involvement of two quadrants to entire conjuncti bulbi. The main related factors for SCH were hypertension (24.3%), heperlipemia(15.1%) and diabetes(9.6%). Idiopathic SCH was found in 345 patients(48.5%). The extent of SCH had no correlation with age or medical history.<br />

Conclusions: SCH is more commonly seen in female and in the temporal side of the conjunctiva. SCH was commonly seen between 71 and 80 years of age and the incidence increased with age. The extension of SCH was not related to the medical history. Our results suggest that SCH could be an age-related disease.<br />
