Study finds, Relationship between Myopic choroidal neovascul
Researchers aimed to study perforating scleral vessels (PSV) in patients with high myopia with swept-source optical coherence tomography (SS-OCT) and to determine their relationship with myopic choroidal neovascularization (mCNV) and its activity.

Retrospective analysis was done of patients with high myopia using multimodal imaging. The presence of PSVs and mCNV was assessed using SS-OCT images.

Results:
--564 eyes from 297 highly myopic patients were studied. 155 eyes showed signs of mCNV while PSVs were found in 500 eyes.

--PSVs were found in 93.5% of eyes with mCNV and they were under or in contact with the mCNV in 80.6 %.

--The mean number of intravitreal injections (IVI) received by mCNV patients was 4.06±4.17 along 66.9±4.1 months of follow-up.

--The number of injections per year was 1.32±1.56, the mean number of relapses was 1.11±1.83 and the mean number of relapses/year was 0.25±0.41.

PSVs are more common in extremely myopic patients with neovascular problems, concluding. On OCT, myopic CNV complexes that coincide with PSVs have higher rates of activity, requiring more injections to regulate and being more prone to relapses over time.
