Relevance. With regard to the variety of retinopathy of prematurity (ROP) course, the issues of treatment tactics in post-threshold stages of the active phase of the disease remain controversial, especially in cases of untimely detection and referral of children with ROP. Considering the high risks of progression of post-threshold retinopathy of prematurity, we proposed a modified technique of “extended” transpupillary laser coagulation in pattern mode using the PASCAL technology, which allows increasing the effectiveness of the treatment and reducing the risk of further ROP progression into the IV stage of the process.
Objective ― to analyze the clinical and functional results of the III post-threshold stage of active ROP treatment using the modified technology of pattern laser coagulation (PASCAL).
Material and methods. Of the premature babies undergoing treatment for active ROP, 60 patients were screened in 2 observation groups (30 patients each) with confirmed by additional postoperative diagnostic methods the 3rd stage of the disease. In the 1st group, laser treatment was performed on a semi-automated scanning device Pascal Photocoagulator (Optimedica, the USA) in the pattern mode by a modified extended technique. In the 2nd group (30 children, 60 eyes), laser coagulation was performed according to the standard procedure in the pattern mode.
Results. In the 1st group, in all cases, a stable regression of the disease was achieved, while the regression rate was significantly higher (p<0.01), in comparison with the 2nd study group with the standard laser treatment technique.
In the 2nd group ― in 10 cases in the early period there was a progression of the process, requiring an additional laser coagulation posterior to ridge in the 2nd session.
Conclusion. Application of modified technology of pattern laser coagulation provides a high-frequency regression of the disease in the active period and does not lead to significant refractive disorders in long-term follow-up period in comparison to the standard technique of laser treatment.
Key words: retinopathy of prematurity, laser coagulation, pattern.
