Swept-source OCTA is a reproducible technique in the assessment of macular perfusion in diabetic patients with special regards to foveal avascular zone analysis. The agreement with FFA is limited especially for diabetic macular ischemia grading. Fundus fluorescein angiography is more sensitive in identifying microaneurysms.

Purpose To demonstrate a modified technique of perfluorocarbon liquid (PFCL)/internal limiting membrane (ILM) interface staining in patients affected by macular hole retinal detachment (MHRD) in the setting of high myopia. Methods Two-surgeon retrospective case series and review of surgical videos with step-by-step technique analysis. Results Our modified technique was proficiently employed to treat 9 highly myopic patients affected by MHRD. Successful staining and peeling of the ILM with the creation of an inverted flap was achieved in all cases. A limited number of dye injections required to stain the ILM was noted. No subretinal dye migration or other intra- and postoperative complications were recorded. Conclusion Modified PFCL/ILM interface staining is a surgically efficient technique potentially reducing the risk of iatrogenic damage, including the toxicity of vital dyes to the retinal pigment epithelium (RPE) in myopic MHRD.
