Multiple images made by extremely high contrast light sources as seen by a person with keratoconus. The classic symptom of keratoconus is the perception of multiple "ghost" images, known as monocular polyopia. This effect is most clearly seen with a high contrast field, such as a point of light on a dark background. Instead of seeing just one ...
Keratoconus, a progressive, noninflammatory, bilateral, asymmetric disease, characterized by paraxial stromal thinning and weakening that leads to corneal surface distortion. [2] Keratoglobus, a rare noninflammatory corneal thinning disorder, characterised by generalised thinning and globular protrusion of the cornea. [3]
Symptoms may also be described as itchy, stinging or tired eyes. [13] [15] Other symptoms are pain, redness, a pulling sensation, and pressure behind the eye. [4] [13] There may be a feeling that something, such as a speck of dirt, is in the eye. [4] [13] The resultant damage to the eye's surface increases discomfort and sensitivity to bright ...
The symptoms of phlyctenular keratoconjunctivitis are primarily treated with application of an appropriate corticosteroid eye drop, such as prednisolone acetate (Pred Forte) or loteprednol (Lotemax). Loteprednol is increasingly preferred due to its lower risk of elevating intraocular pressure. The corticosteroid suppresses the immune response ...
Ulcerative vernal keratitis require surgical treatment in the form of debridement, superficial keratectomy, excimer laser therapeutic keratectomy, as well as amniotic membrane transplantation to enhance re-epithelialisation. Recently treatment with tacrolimus ointment (0.1%) used topically twice daily is showing encouraging results.
Neurotrophic keratitis (NK) is a degenerative disease of the cornea caused by damage of the trigeminal nerve, [1] which results in impairment of corneal sensitivity, spontaneous corneal epithelium breakdown, poor corneal healing and development of corneal ulceration, melting and perforation. [2]
This treatment uses synthetic testosterone to increase circulating testosterone levels and reduce low T symptoms. TRT comes in several forms, including skin patches, topical gels, oral capsules ...
Thygeson's superficial punctate keratopathy (TSPK) is a disease of the eyes.The causes of TSPK are not currently known, but details of the disease were first published in the Journal of the American Medical Association in 1950 by American ophthalmologist Phillips Thygeson (1903–2002), after whom it is named.
