Our study showed that a graduated cyclocryotherapy over a period, titrated according to the intra ocular pressure, is generally not associated with phthisis bulb. For many people, retinal haemorrhage and macular swelling will end in a few months, with retention of good vision. Oct. 121:1939-48. It is also important to stress to the patient that the treatment is simply helping to reduce or eliminate macular enema to prevent long term permanent macular changes, and that it is NOT a cure for the CRVO which has to take its own natural course. Am J Ophthalmol. 2008 Aug. 1462:285-291. The retina at the back of the eye is a light-sensitive layer which consists of rod and cone cells. Thus, if an eye can see I-2e or has normal visual fields with I-2e, that is definitely in favour of being a non-ischemic CRVO. In a few but not all cases a laser can be used in this type of occlusion to help control bleeding and swelling, and can mean that sight improves a little.
