The purpose of this article was to describe a patient with dome-shaped macula in the setting of mild myopic anisometropia and to speculate regarding the role of this feature as a compensatory mechanism in ocular development. The clinical records of a 49-year-old woman with this condition were reviewed. Spectral-domain optical coherence tomographic images revealed evidence of a dome-shaped macula. B-scan ultrasonography measured axial lengths of 23.8 mm in the right eye and 22.8 mm in the left eye. Spherical equivalents were -1.375 and +0.375 in the right and left eyes, respectively. Examination of the left eye was unremarkable. Dome-shaped macula has previously only been described in patients with high myopia. These findings support the hypothesis that myopic anisometropia, rather than absolute refractive status, is central to the development of dome-shaped macula and that this feature represents a protective mechanism aimed at reducing the effects of anisometropia.

Purpose: To describe a new feature in pathologic myopia: perivascular patchy chorioretinal atrophy (PVCA) DESIGN: Cross-sectional study METHODS: 604 eyes of 312 highly myopic patients followed at Strasbourg University Hospitals were reviewed for the presence of PVCA lesions. Demographic, clinical, and paraclinical data (ultra-widefield retinography, optical coherence tomography (OCT), fluorescein and indocyanine green angiography images) were analyzed. Controls were matched for age, sex, and axial length (AL).

Article Synopsis
- The review summarizes the clinical and anatomical aspects of myopia, highlighting the different stages of myopic maculopathy (MMP) and their association with retinal changes.
- Recent findings show that MMP stage-4 is linked to defects in Bruch's membrane and previous macular neovascularization, while stage-3 demonstrates differences based on the presence of these defects.
- Additionally, higher axial lengths in myopic eyes correlate with increased risks for vision loss and certain eye conditions, including open-angle glaucoma, emphasizing the complexity and implications of myopia in aging populations.
A case of acute idiopathic maculopathy in both eyes with peripheral vascular occlusion.

Background: This study aimed to present a case of bilateral symmetric onset of acute idiopathic maculopathy after high fever with peripheral vascular occlusion.
Case Presentation: A 54-year-old yellow female experienced acute binocular visual acuity decrease after 1 day of high fever, and binocular visual acuity decreased to index or anterior. OCT in the external hospital showed dome-shaped cortical detachment in the symmetrical macular area of both eyes with subretinal fluid, discontinuity in the ellipsoid zone and the chimera.
Semi-Automated Analysis of Dome-Shaped Macula in Preterm and Full-Term Infants Using Handheld Swept-Source Optical Coherence Tomography.

Article Synopsis
- The study investigates dome-shaped macula (DSM) in preterm and full-term infants using advanced optical imaging technology, highlighting increased occurrence in preterm infants.
- Out of 217 imaging sessions, DSM was found in 40% of preterm infants compared to 14% of full-term infants, showing a significant difference in diagnosis timing and dome characteristics.
- The results suggest that while DSM is common in infants and typically round in shape, it isn't linked to macular fluid presence, indicating unique differences from DSM in older children and adults.

Background: To investigate the visual acuity outcome and choroid thickness (CT) change after intravitreal ranibizumab in highly myopic eyes with or without dome-shaped macula (DSM) in Chinese patients.
Methods: This retrospective, observative study included 80 treatment-naive eyes (80 patients), which received ranibizumab according to the 1+PRN protocol. The best corrective visual acuity (BCVA) and CT change were compared between eyes with or without DSM.
