Purpose: To document with spectral domain optical coherence tomography the formation and spontaneous closure of small full-thickness macular holes and to propose the active role of Müller cells in macular hole closure.
Methods: A retrospective case series of five patients with spontaneous closure of macular holes is reviewed. In one patient, foveal images were recorded over a period of 18 months.
Purpose: To assess whether residual refractive error after in-the-bag multifocal intraocular lens (mIOL) implantation can efficaciously and safely be corrected with a piggy-back low power Visian Toric Implantable Collamer Lens (VTICL, STAAR Surgical) placed in the ciliary sulcus.
Patients And Methods: Twenty-four eyes of 23 patients (mean age: 57.5 years) with diminished uncorrected distance visual acuity (UDVA) of ≥2 lines due to residual refractive error after mIOL implantation were included in the study.
Objectives/methods: The aim of this study was to verify the formation of hydroxyl radicals (·OH) after ultraviolet A (UVA) irradiation of riboflavin (RF) by spin trapping with 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), and electron spin resonance spectroscopy.
Results: We found that ·OH were generated via hydrogen peroxide (H₂O₂) formation during UVA irradiation of RF. The ·OH radicals were trapped with DMPO yielding 2-hydroxy-5,5-dimethyl-1-pyrroline-N-oxide (·DMPO-OH).
