OBSERVATION VS. SURGERY IN TRAUMATIC MACULAR HOLE: A CASE REPORT HIGHLIGHTING FUNCTIONAL OUTCOME

IJRETINA (International Journal of Retina)
Introduction: Traumatic macular hole (TMH) is a rare consequence of blunt ocular trauma, often leading to visual impairment. While spontaneous closure is possible, the decision between observation and surgical intervention remains debated. Case Report:

The Hole Story: Spontaneous Closure after Reopening

Case Reports in Ophthalmology
<p>Introduction: We report a case of spontaneous closure after early reopening of a previously successfully treated macular hole (MH). Case Presentation: A 73-year-old patient presented with visual acuity of 20/100 and complained of defective vision. Examination and investigations confirmed a full-thickness MH.

Nanoconfinement‐Induced Second‐Harmonic Circular Dichroism via Chirality–Ferroelectric Coupling

Advanced Functional Materials, EarlyView.
Nanoconfinement of a ferroelectric nematic liquid crystal within a chiral nanoporous sponge yields an enhanced second‐harmonic generation circular dichroism (|gSHG–CD| ≈ 1.1). Polarization‐resolved analysis suggests an additional magnetic‐dipole‐associated nonlinear contribution under nanoconfinement, highlighting chirality–ferroelectric coupling as a ...

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

Advanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

Advanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

Spontaneous closure of macular hole.

Journal of the College of Physicians and Surgeons--Pakistan : JCPSP, 2015
We report a case of spontaneous closure of stage-II macular hole. A 66 years old lady presented with decreased vision in her left eye for the last 3 months. Her vision was 6/18 in right eye and finger counting at 3 feet in left eye. Optical coherence tomography showed stage-II macular hole in left eye.
