background: astigmatism is the leading complication in visual recovery after penetrating keratoplasty (pkp) and deep anterior lamellar keratoplasty (dalk); in this study, we evaluated the outcome of femtosecond laser arcuate keratotomy (flak) after dalk and pkp in iranian keratoconic patients. materials and methods: in this prospective interventional case series, refractive and keratometric pre...

A successful corneal graft requires both clarity and an acceptable refraction. A clear corneal graft may be an optical failure if high astigmatism limits visual acuity. Intraoperative measures to reduce postkeratoplasty astigmatism include round and central trephination of cornea with an adequate size, appropriate sutures with evenly distributed tension, and perfect graft-host apposition. Sutur...

Glaucoma is a chronic eye disease and the second most leading cause of irreversible impaired vision in world, which primarily linked with high intraocular pressure (IOP). The treatment glaucoma currently challenging because innate mechanics ocular barriers that limit penetration ophthalmic drugs. To tackle this, various carriers (inorganic-, polymeric-, hydrogel-, or contact lens–based) special...

The literature analysis confirms the interrelationship of thyroid gland pathology and glaucoma. Patients with diffusetoxic goiter (DTG) endemic have an especially high risk developing glaucoma, while those autoimmune thyroiditis face a moderate risk. prevalence primary open angle glaucoma (POAG) in patients over 40 endocrine ophthalmopathy is reliably associated male gender duration disease lon...

Glaucoma is the leading cause of irreversible vision loss and second blindness worldwide. The rapid transmission SARS-CoV-2virus compelled governments to concentrate their efforts on emergency units treat large number cases that arose due Covid-19 outbreak. As a result, many chronically ill patients were left without access medical care. progression glaucoma in previously diagnosed has been acc...

Objectives To explore the acceptability of home visual field (VF) testing using Eyecatcher among people with glaucoma participating in a 6-month monitoring pilot study. Design Qualitative study face-to-face semistructured interviews. Transcripts were analysed thematic analysis. Setting Participants recruited UK through an advertisement International Glaucoma Association (now UK) newsletter. Twe...

glaucoma is the second leading cause of irreversible blindness and a neurodegenerative disease with a complex pathogenesis. increasing evidence suggests that oxidative stress and mitochondrial dysfunction have crucial roles in most neurodegenerative diseases such as glaucoma. the conventional clinical treatment for glaucoma is lowering the intraocular pressure (iop). some patients have normal i...
