| Summary: |
The aim of the study:
Central retinal vein occlusion (CRVO) is one of the most
common retinal vascular disorders and is often
associated with significant visual loss. It is thought
to arise from vascular obstruction at the level of
lamina cribrosa. Radial optic neurotomy (RON) is an
alternative treatment method for central retinal vein
occlusion. Poor visual prognosis in patients with 0.1 or
worse initial visual acuity is still a therapeutic
challenge. RON may bye a beneficial surgical procedure
for these patients. Authors present the RON procedure
results of clinical study and own experience.
Material and methods: Eleven eyes of 11 patients
with central retinal vein occlusion lasting not longer
than 3 months and with visual acuity Ł 0.1 underwent
radial optic neurotomy.
Results: Improvement of visual acuity was
observed in 90% of operated cases. Four out of eleven
patients developed chorioretinal venous anastomosis. No
serious complications were noticed.
Conclusion: Radial optic neurotomy can be
beneficial for patients threatened with visual loss
caused by central retinal vein occlusion. This procedure
seems to be free from significant intra- and
postoperative complications. However, in common with all
previous reports, the current study is limited by the
small number of patients included. Further randomized
and controlled clinical studies are necessary to
establish safety and efficacy of this technique. |
