Purpose:

To analyze the results of YAG-laser retinopuncture use for the treatment of cystoid macular edema caused by thrombosis of central retinal vein and its branches.

Methods:

Eighty patients with cystoid macular edema caused by thrombosis of central retinal vein and its branches were included in the study. Influence of patient’s age, thrombosis location and duration on visual acuity, retinal thickness and volume was studied by optical coherence tomography (OCT).

Results:

OCT data showed that CMO is a group of communicating intraretinal cavities possessing a property of volume and shape changing and influencing visual functions. A method of CMO treatment with YAG-laser retinopuncture was developed. In the result of this method employment in 50 patients of the investigated group emptying of cystic cavities was achieved, the retina in the macular region was attached and statistically significant increase of BCVA from 0.04±0.005 to 0.3±0.02 was seen. It was found that patient’s age from 50 to 60 years, thrombosis location in the inferotemporal branch of central retinal vein and its duration less than 3 months were the factors significantly improving visual acuity after laser retinopuncture.

Conclusion:

YAG-laser retinopuncture performing provides emptying of cystic cavities, attachment of the macula and thus improvement and stabilization of visual functions.

Take-home message:

YAG-laser retinopuncture provides emptying of cystic cavities and improvement of visual acuity in cases of cystoid macular edema caused by thrombosis of central retinal veins and its branches with better results in younger patients, relatively fresh CMO and thrombosis location in the inferotemporal branch of central retinal vein.
