Purpose:
To prospectively examine changes in retinal light sensitivity following blunt ocular trauma in eyes with traumatic hyphaema with no evidence of retinal injuries 1 week, 1 month and 4 months after injury.
Method:
Sixteen patients who sustained hyphaema after blunt ocular trauma without visible traumatic retinal lesions underwent visual field testing on the C 30-2 programme of the Humphrey field analyser as soon as visual acuity recovered to 0.7 or more with correction.
Results:
Significant reduction in retinal sensitivity with MD (mean deviation) p values less than 5% was found in 50% (8 eyes) of our patients 1 week after injury. MD p values significantly improved 1 month after injury (p < 0.001) and even more so after 4 months (p < 0.00004). After 4 months only in one eye (6%) was a significant reduction in retinal sensitivity observed with a MD p value less than 5%. No correlations between improvement in retinal sensitivity and the extent of hyphaema or the extent of angle recession were observed.
Conclusions:
In 50% of eyes following blunt ocular trauma without evident traumatic posterior segment abnormalities significant transient reduction in retinal light sensitivity was observed with nearly complete recovery over time.
