Versatility of use of fibrin glue in wound closure and vitreo-retinal surgery.

Int J Retina Vitreous 2021 Apr 15;7(1):33. Epub 2021 Apr 15.

Retina and Vitreus Department, Asociacion para Evitar la Ceguera en México, IAP, Vicente García Torres 46, Col. Barrio San Lucas, Coyoacan, 04030, Mexico City, Mexico.

Background: Fibrin glue is an absorbable blood-derived product, a biological tissue adhesive which imitates the final stages of the coagulation cascade, it produces a firm clot, forming a seal along the whole length of the wound, the resultant fibrin clot degrades physiologically into granulation tissue 2 weeks after the application. Biological glue has been used extensively in many forms of surgical procedures. Its use in eye surgery has grown lately as we have evidence that showed it was effective in securing conjunctival grafts in pterygium surgery, in securing wounds after glaucoma surgery and more importantly in 20G and 23G vitrectomy.

Clinical update on metamorphopsia: epidemiology, diagnosis and imaging.

Curr Eye Res 2021 Apr 7. Epub 2021 Apr 7.

NIHR Biomedical Research Centre at Moorfields Eye Hospital and UCL Institute of Ophthalmology, London, United Kingdom.

Purpose: To discuss the pathophysiology of metamorphopsia, its characterisation using retinal imaging and methods of assessment of patient symptoms and visual function.

Methods: A literature search of electronic databases was performedResults: Metamorphopsia has commonly been associated with vitreomacular interface disorders (such as epiretinal membrane) and has also regularly been noted in diseases of the retina and choroid, particularly age-related macular degeneration and central serous chorioretinopathy. Developments in optical coherence tomography retinal imaging have enabled improved imaging of the foveal microstructure and have led to the localisation of the pathophysiology of metamorphopsia within the retinal layers of the macula.
