[The surgical prophylaxis stage in the progression of myopia in children]
Insights
Simplified sclera-enhancing surgeries show varied effectiveness in stabilizing progressive myopia in children. The best method depends on the myopia stage, with specific techniques proving more beneficial for initial, advanced, or far-advanced cases.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Surgical Innovation
Background:
- Axial progressive myopia is a significant cause of visual impairment in children.
- Sclera-enhancing operations are explored to stabilize myopia progression.
- Various surgical techniques and biomaterials are used, necessitating evaluation of their efficacy.
Purpose of the Study:
- To evaluate the effectiveness of simplified sclera-enhancing operations in stabilizing axial progressive myopia in children.
- To compare the outcomes of different surgical methods (Pristavko-Pivovarov, Malysheva, Remizov-Griaznov) based on myopia stage.
- To assess the impact of different plastic materials (allosclera, dura mater, collagenous sponge) on surgical outcomes.
Main Methods:
- A study involving 211 children (410 eyes) aged 7-15 years with axial progressive myopia.
- Myopia ranged from 2.5 to 20 D, encompassing initial, advanced, and far-advanced stages.
- Follow-up duration was between 6 months and 3 years post-surgery.
Main Results:
- The Pristavko-Pivovarov method showed positive effects more frequently in initial myopia.
- The Malysheva method was more effective for advanced myopia stages.
- The Remizov-Griaznov method demonstrated better outcomes in far-advanced myopia.
- For the Pristavko-Pivovarov technique, allosclera from newborns was more effective than dura mater or collagenous sponge.
Conclusions:
- Simplified sclera-enhancing operations can contribute to myopia stabilization in children.
- The choice of surgical technique should be tailored to the specific stage of axial progressive myopia.
- Material selection, such as using allosclera, is crucial for optimizing outcomes in certain surgical approaches.
Abstract:
The effect of common "simplified" methods of sclera-enhancing operations using various plastic materials on stabilization of the process has been studied in 211 children (410 eyes), aged from 7 to 15 years, with axial progressive myopia from 2.5 to 20 D of initial, advanced, far-advanced stages of the disease. The follow-up period ranged from 6 months to 3 years. A positive effect of scleroplasty after Pristavko-Pivovarov is observed more frequently in cases of initial myopia, after Malysheva--of advanced, after Remizov-Griaznov--of far-advanced stages of the disease. In operations after Pristavko-Pivovarov, allosclera in newborns is more effective, than dura mater or a collagenous sponge.
