I remember the summer day when Neelam came to me for an eye check-up. She was in a panic mode and was blaming her husband for her miserable condition. She needed his support to walk as she was unable to see clearly. I calmed her down and examined her eye. She had a vitreous hemorrhage in one eye and the other eye had lost vision due an eye injury in childhood. So, she was managing herself with one eye all these years. Now because of the bleeding inside the cavity of her eye she suddenly lost her vision. She was a known diabetic and inspite of her physician’s repeated warnings she didn’t get her eye check-up done. She last checked her eyes 10 years back when everything was declared to be normal. Diabetic retinopathy (DR) is a known complication in long standing diabetics. Regular eye check-ups to detect and control DR is therefore very important. I reassured Neelam and advised her bed rest with head-up position. She gradually resumed part of her vision. We treated her with lasers and injections and her condition improved. Now she comes for regular follow-ups. Lets have a closer look at vitreous hemorrhage and its various causes.
Vitreous hemorrhage is bleeding within cavity of the eyeball. Cavity of eyeball is filled with transparent jelly like structure called Vitreous. This vitreous allows light to pass through cavity of eyeball and fall on Retina where image forms. Most of this humor consists of water, as well as a lower amount of collagen, salt, and sugar. Very high content of water keeps it transparent. So Vitreous hemorrhage is condition where vision gets affected due to bleeding in this transparent jelly. Vision affection may vary from slight blurring of vision to complete loss of vision depending on the amount of bleeding.
The most common causes of vitreous hemorrhage are-
Vitreous hemorrhage can also occur in Wet macular degeneration, Retinal artery macro aneurysm, secondary to subarachnoid hemorrhage (Terson’s syndrome) and various vasculopathies causing neovascularisation. Other rare cases includes blood dyscrasias, Valsalva retinopathy and intraocular tumors.
1) Sudden appearance of floaters - small vitreous hemorrhage
2) Sudden painless loss of vision- large vitreous hemorrhage
Fate of vitreous hemorrhage
Vitreous liquefaction/Degeneration: if Vitreous hemorrhage is left alone it undergoes spontaneous resolution in almost 60% cases, which is best outcome without any intervention. But this is associated with liquification of vitreous jelly.
Ghost cell glaucoma: While undergoing spontaneous resolution, bleeding breaks into fine components which clogs the drainage system of eye leading to increase in intraocular pressure called Ghost cell Glaucoma.
Tractional retinal detachment: If vitreous hemorrhage is dense and left alone, resolution is also associated with surface contraction in vitreous and retina. This leads to tractional retinal detachment.
B scan: Is the investigation of choice if vitreous hemorrhage is quite dense and the retina eye doctor is unable to assess the retina. B-scan shows Retina status, Giant retinal tears and status of vitreous jelly.

FFA : Retinal angiography is useful in cases of Proliferative Diabetic Retinopathy and all other vascular causes of hemorrhage once the vitreous hemorrhage settles down and allow some retinal visibility.
