RELATIONSHIP BETWEEN THE HEIGHT OF WIDE AND NARROW PRIMARY MACULAR STAPHYLOMA AND MYOPIC MACULAR RETINOSCHISIS.

Abstract

To investigate the relationship between the depth of wide and narrow primary macular staphyloma and myopic macular retinoschisis. Sixty-nine highly myopic eyes with wide and narrow primary macular staphyloma were included in this cross-sectional study and classified into two groups according to the presence or absence of myopic macular retinoschisis on swept-source optical coherence tomography. All patients received a complete ophthalmologic examination with determination of macular staphyloma depth by ocular ultrasonography (B-scan). Nine eyes (9/69, 13.04%) present myopic macular retinoschisis on swept-source optical coherence tomography. Eyes with vitreomacular tractions, arteriolar traction, and greater macular staphyloma depth were more likely to develop myopic macular retinoschisis (odds ratio, 11.32; P = 0.001; odds ratio, 6.23; P = 0.039; and odds ratio, 3.37; P = 0.01, respectively). We did not observe statistically significant differences regarding best-corrected visual acuity between eyes with and without myopic macular retinoschisis ( P = 0.39). The depth of the wide and narrow primary macular staphyloma appears to be a new and an important factor in the development of myopic macular retinoschisis.
