Management of Vitreous Haemorrhage.
Pak J Ophthalmol Jan ;16(4):160-5.

For vitreous haemorrhage traditionally we used to wait for six months before interfering surgically. The trends are changing with advancing techniques. Now the decision depend on the patient`s visual, social and emotional desires. On ultrasound if the retina is detached and involves the macula, urgent surgery should be seriously considered. As vitreous haemorrhage may result from a number of conditions and spontaneous resolution may occur, an understanding of the pathological process in the eye is essential in order to rationalize the management of the problem. Retrohyaloid haemorrhage does not clot and thus leads to severe blurring of vision. Bleeding into the gel behaves in two ways. It may clot or it may not clot. When the haemorrhage clots, resolution in slow but vision may be better due to clear areas between the clots. When the blood does not clot, resolution occurs by settling of red blood cells by gravity and the patients have good vision when upright. Simple vitreous haemorrhage does not organize into fibrous tissue except in diabetes and penetrating trauma. A comparison of causes of vitreous haemorrhage with international studies is also presented.
