Purpose: To show a case in which the shape of the fovea changed after an asymptomatic macular posterior vitreous detachment (PVD).
Methods: The foveal shape was determined from the spectral-domain optical coherence tomography (OCT) images before and after a spontaneous macular PVD.
Results: A 66-year-old man with a unilateral macular hole in the right eye presented with a perifoveal PVD in the asymptomatic left eye. One year later, the left eye developed a macular PVD, and OCT measurements showed a 16.7% decrease in the central foveal thickness, and increases in the pit depth by 20.5%, foveola diameter by 14.7%, and pit volume by 19.4%. The thicknesses of the macular subfields of the Early Treatment Diabetic Retinopathy Study were decreased by 13.0% in the central subfield and by 1.4%-6.6% in the other subfields.
Conclusion: The deepening and widening of the fovea after a macular PVD indicate that a PVD can alter the shape of the fovea.

Purpose: To describe a rare case of presumed bilateral acute idiopathic maculopathy (AIM) in a pediatric patient.
Observation: An 11-year-old male was evaluated for a "fuzzy Dorito-shaped" spot in the central vision of his right eye (OD) that started 3 days before presenting to our clinic. On examination, best-corrected visual acuity (BCVA) was counting fingers at 5 feet OD, and 20/25 in the left eye (OS).
Multiple parafoveal retinal detachment in myopic tractional maculopathy.

Department of Ophthalmology, Taipei Veterans General Hospital, Taipei, Taiwan.
This study investigates the occurrence of multiple parafoveal retinal detachments (RDs) in myopic traction maculopathy (MTM), emphasizing the atypical extrafoveal involvement compared to central foveal detachment commonly observed. Patient 1, a 46-year-old male, exhibited MTM with retinoschisis and four small subretinal fluid (SRF) pockets inferior to the fovea, accompanied by a hyperautofluorescent vitelliform deposit. Patient 2, a 43-year-old male, reported ring-shaped dim vision in the left eye, displaying MTM with six stable SRF pockets surrounding the fovea.

To describe a modified technique for negative and positive (Yin-Yang) staining of the internal limiting membrane (ILM) to create a nonstained ILM flap that covers large idiopathic macular holes (MHs). Consecutive patients with large idiopathic MHs (>400 μm) were prospectively included in the study. After the central vitreous was removed, a droplet of triamcinolone acetonide was injected, covering the MH and surrounding area.

The visual system compensates for differences between peripheral and foveal vision using different mechanisms. Although peripheral vision is characterized by higher spatial uncertainty and lower resolution than foveal vision, observers reported objects to be less distorted and less blurry in the periphery than the fovea in a visual matching task during fixation (Valsecchi et al., 2018).
