Combined Brilliant and Trypan Blue As Vital Dyes for Chromovitrectomy.

Brilliant blue 0.05% and trypan blue 0.1% were mixed in a proportion of 1:1 in a 1-mL syringe.

Incidence and risk factors of postoperative visual function impairment in elderly patients undergoing nonocular surgery: a prospective cohort study.

Background: Elderly patients may present with visual function impairment after surgery, which may increase the incidence of postoperative delirium and falls and decrease their quality of life. The aim of this study was to assess visual function in elderly patients after long-duration nonocular surgery to determine the incidence and risk factors for visual function impairment after surgery.

Methods: This prospective and observational study included patients aged between 60 and 80 years who had been scheduled for elective nonocular surgery expected to last longer than 120 minutes under general anesthesia.

RETINAL RACEMOSE HEMANGIOMA WITH FOCAL MACULAR INVOLVEMENT.

Purpose: To report a case of racemose hemangioma with macular involvement and treated with anti-vascular endothelial growth factor.

Methods: Observational case report.

Results: JFS, a 31-year-old woman, presented with a complaint of blurred vision in her right eye over the preceding 2 months, worsening during the previous month.

[Optical coherence tomography macular study on eyes filled with silicone oil].

Purpose: To demonstrate optical coherence tomography efficacy to evaluate macular anatomical outcomes, in eyes with silicone oil-filled vitreous cavity after vitrectomy.

Methods: A descriptive observational study of 28 (twenty-eight) patients submitted to pars plana vitrectomy having silicone oil as vitreous substitute. The macular findings were observed by means of indirect binocular ophthalmoscope, biomicroscopy and optical coherence tomography examinations.

[A study of idiophatic vitreomacular traction syndrome with optical coherence tomography images: cases report].

Purpose: To evaluate the features of idiophatic vitreomacular traction syndrome (VMT) with ocular coherence tomography (OCT--Stratus), before and after vitrectomy; to identify situations where ocular coherence tomography provides additional information on disease morphology and pathogenesis.

Methods: Comparative retinal ocular coherence tomography imaging was performed in four patients with different stages of vitreomacular traction syndrome.

Results: Standard-resolution ocular coherence tomography Stratus provides vitreous-retinal images that help the management and treatment of vitreomacular traction syndrome.

[Late opacification of a polymethylmethacrylate (PMMA) intraocular lens: case report].

The use of intraocular lenses was a great advance in visual recovery after cataract surgery. Although usually with good biocompatibility, some alterations in the intraocular lens material may occur after implantation. Polymethylmethacrylate was the first intraocular lens material to be used on a large scale and assumed to be inert and well-tolerated.
