Retina Vein Occlusion

Retina vein occlusion is a block in the retina vein, it may affect part of a retina (branch retina vein occlusion), half or entire retina (hemi or central retina vein occlusion). Most often, this is associated with hypertension, diabetes and hypercholesterolemia

sequelae of vein occlusion

New Vessels

In a subset of patients, retina vein occlusion unfortunately leads to sequelae such as new vessel formation. The underlying cause is ischaemia (which is diminished blood supply, resulting in shortage of oxygen). Treatment such as panretina photocoagulation (retina laser) is usually required to prevent long term visual loss.

Macular Oedema

Another known sequelae of retina vein occlusion is formation of macular oedema or fluid in the macular. Depending on the location of the fluid and patient's vision, several treatment options may be available including intravitreal injections with antivegf, steroid or macular laser.

Ms Heng will evaluate the individual pathology and treatment option with the patient and advise on tailored therapeutic option for the patient.
