“…Although it is natural that teenagers have a better BCVA than older adults, the different severity of MDC between teenagers and older adults with MRS may also contribute to their difference in BCVA. In contrast to severe MDC (Ohno-Matsui Categery 3 and Categery 4) frequently reported in patients over 50 years1234567891213, only mild (Ohno-Matsui Categery 1, 4/13 eyes) and moderate MDC (Ohno-Matsui Categery 2, 9/13 eyes) were found in teenage patients in our study. The milder MDC may contribute to the preserved oxygen and nutrient diffusion from choriocapillary layer to photoreceptors and inner neuroretina for their vitality and to maintain a fairly good visual acuity20.…”

“…Another important finding of our study is that most MRS eyes in teenagers showed fairly good (≥0.3, 9/13 eyes) or good BCVA (≥0.8, 3/13 eyes), which was much better than the BCVA reported in MRS patients over 50 years1234567891213. Although it is natural that teenagers have a better BCVA than older adults, the different severity of MDC between teenagers and older adults with MRS may also contribute to their difference in BCVA.…”

“…MRS occurred most often in patients over 50 years in previous reports, and was usually accompanied with staphyloma, severe myopic macular atrophy and premacular structures such as macular epiretinal membrane or partially detached posterior hyaloids, which makes it difficult to identify what causes MRS123456789101213. A multivariate analysis showed that three factors were independently associated with foveoschisis in high myopia: axial length, macular chorioretinal atrophy, and vitreoretinal traction14.…”

“…Only OCT images exactly centered on the foveola were chosen for analyses. MRS was defined as the splitting of intraretinal tissues including outer macular retinoschisis (outer plexiform layer splitting), inner macular retinoschisis (inner plexiform layer splitting), and internal limiting membrane detachment in macular area accompanied by either continuous or discontinuous bridging tissues in splitting cavities123456789. Patients with cystic cavities alone in the fovea in OCT images further underwent family survey to exclude X-linked hereditary juvenile retinoschisis24.…”

“…Macular retinoschisis is one of the severe complications of high myopia which could lead to severe visual loss 1 2 3 4 5 . Although myopic macular retinoschisis (MRS) was first identified in 1999 by using optical coherence tomography (OCT), the initiation cause and pathogenesis of MRS remain unclear 1 2 3 4 5 . Most MRS was reported in older patients over 50, no report showed it occurred in teenager patients 1 2 3 4 5 6 7 8 .…”

To investigate the morphological characteristics of myopic macular retinoschisis (MRS) in teenagers with high myopia, six male (9 eyes) and 3 female (4 eyes) teenagers with typical MRS identified from chart review were evaluated. All cases underwent complete ophthalmic examinations including best corrected visual acuity (BCVA), indirect ophthalmoscopy, colour fundus photography, B-type ultrasonography, axial length measurement, and spectral-domain optical coherence tomography (SD-OCT). The average age was 17.8 ± 1.5 years, average refractive error was −17.04 ± 3.04D, average BCVA was 0.43 ± 0.61, and average axial length was 30.42 ± 1.71 mm. Myopic macular degenerative changes (MDC) by colour fundus photographs revealed Ohno-Matsui Category 1 in 4 eyes, and Category 2 in 9 eyes. Posterior staphyloma was found in 9 eyes. SD-OCT showed outer MRS in all 13 eyes, internal limiting membrane detachment in 7 eyes, vascular microfolds in 2 eyes, and inner MRS in 1 eye. No premacular structures such as macular epiretinal membrane or partially detached posterior hyaloids were found. Our results showed that MRS rarely occurred in highly myopic teenagers, and was not accompanied by premacular structures, severe MDC, or even obvious posterior staphyloma. This finding indicates that posterior scleral expansion is probably the main cause of MRS.

Purpose To investigate the clinical characteristics, internal correlations and risk factors for different locations of retinoschisis (RS) in an elderly high myopia (HM) population. Methods A total of 448 eyes (304 participants) were analysed and classified into no retinoschisis (no‐RS), paravascular retinoschisis (PVRS), peripapillary retinoschisis (PPRS) and macular retinoschisis (MRS) groups. Each participant underwent comprehensive ophthalmic examinations, and posterior scleral height (PSH) was measured in swept‐source optical coherence tomography images. PSH, vitreoretinal interface abnormities and myopic atrophy maculopathy (MAM) were compared among groups. Results Retinoschisis was found in 195 (43.5%) eyes, among which 170 (37.9%) had PVRS, 123 (27.5%) had PPRS, and 103 (23.0%) had MRS. MRS was found to be combined with PVRS in 96 of 103 (93.2%) eyes. MAM was one of the risk factors for RS (odds ratio [OR], 2.459; p = 0.005). Higher nasal PSH was the only risk factor for PVRS (OR, 9.103; p = 0.008 per 1‐mm increase). Elongation of axial length (AL) (OR, 1.891; p < 0.001 per 1‐mm increase), higher PSH in nasal (OR, 5.059; p = 0.009 per 1‐mm increase) and temporal (OR, 13.021; p = 0.012 per 1‐mm increase), epiretinal membrane (ERM; OR, 2.841; p = 0.008) and vitreomacular traction (VMT; OR, 7.335; p = 0.002) were risk factors for MRS. Conclusions Paravascular retinoschisis is the most common type of RS in HM and MRS is mostly combined with PVRS. MAM is one of the risk factors for RS. In addition to longer AL and higher PSH, the presence of VMT and ERM also play an important role in the formation of MRS.
