Abstract： Objective To evaluate the clinical features of macular retinoschisis (MRS) and macular retinal detachment without hole (MRDH) in highly myopic eyes. MethodsThe clinical data of 19 patients (24 eyes) with MRS and MRDH from 186 patients (349 eyes) with high myopia were retrospectively analyzed. All of the patients had undergone the examinations of subjective refraction, binocular indirect ophthalmoscope, slit lamp microscope combined with Goldmann three-mirror contact lens, fundus images, A/B-scan uhrasonography, and optical coherence tomography (OCT). Results In 349 eyes, 24 (6.9%) had MRS and (or) MRDH at the posterior pole. The results of ocualr fundus examinations showed that all of the 24 eyes (100%) had posterior scleral staphyloma (PS), 2 (8.3%) had vitreomacular traction (VMT), 2 (8.3%) had macular local superficial retinal detachment, and 1 (4.2%) had full-thickness macular hole. The results of B-scan uhrasonography also indicated PS in all 24 eyes (100 %), macular local superficial retinal detachment in 7 (29.2%) with a bow-like configuration formed by the detached retina and the cone-shaped roof of PS, and VMT in 2 (8.3%). The results of OCT revealed macular outer-layer retinoschisis (ORS) in 22 eyes (91.7%) in which 8 (36.4%) also had macular inner-layer retinoschisis (IRS); MRDH in 5 eyes (20.8%) in which ORS was found in 3 (60.0%) and simplex MRDH in 2 (40.0%) including 1 with VMT; VMT in 13 eyes (54.2%); cystoid macular edema (CME) in 3 eyes (12.5%); and lamellar macular hole in 4 eyes (16.7%) . Conclusions MRS and MRDH are common complications in highly myopic eyes with posterior scleral staphyloma. OCT is more sensitive and accurate in detecting MRS and MRDH than routine ophthalmoscopic examination and B-scan ultrasonography.
