Hypotony is a common complication following trabeculectomy in which an
timetabolites are used. Autologous blood injection is an accepted form
of treatment for hypotony that occurs secondary to overfiltration; ho
wever, injection into the filtering bleb has been associated with a ri
se in intraocular pressure for some patients with chronic postoperativ
e hypotony. The authors describe a patient in whom corneal blood stain
ing with raised intraocular pressure and loss of vision occurred as a
result of autologous blood injection.
