PURPOSE: To study the type, size, location and posterior time evolution of the subretinal neovascular membranes (SRNM) secondary to degenerative myopia (DM) and its relationship with the degree of myopic ametropia.
METHODS: We studied 65 patients (130 eyes) with MD who were divided into three groups according to their refraction. A complete ophthalmologic examination, including a fluorescein angiography (FAG), was performed for all the patients. Based on this test, 55 SRNA were identified, and were classified into two types according to the fluorescein angiography results. Their position was described in relationship to the foveal avascular zone (FAZ) and their size was measured.
RESULTS: 55 (42.3%) of the 130 eyes presented SRNM, which was bilateral in 16.32% of the patients. Based on the FAG criteria, 41 eyes (74.54%) presented type 1 SRNM, 60% (33 eyes) presented subfoveal membranes and the size was greater than 1,500 microns in more than 75%. The development of the SRNM showed no relationship with the myopic ametropia degree (P<0.2500). The follow-up time was 24.61+/-7.63.
CONCLUSIONS: No relationship between the appearance of the development of the SRNM and the myopia degree has been found. These are generally small sized, have poor dye diffusion and are frequently located in the foveal zone. The visual acuity loss is often sudden and maintained over time.
