Degenerative eye conditions - Coggle Diagram
Degenerative eye conditions
Degenerative of the eyelids
Entropion: this is a turning inward of the lid condition may be congenital due to ageing due to scarring following trauma to the eye
Ectropion: this is everision of the lower led usually bilateral the condition maybe congenital age-related
Signs and symptoms: include watering of the eye irritation and keratitis
Degenerative of the sclera
Staphyloma of the sclera: a staphyloma is a thinning and protrusion of part of the eyeball lined with uveal tissue
is caused by severe and prolonged increased intraocular pressure thinning of the sclera
Signs and symptoms:include lagophthalmos, conjunctivitis, lacrimation, ocular hypertension nearly always
Degenerative of the cornea
Ketatoconus: this is a hereditary degenerative bilateral condition of the cornea that's rarely represents before puberty
Arcus senilis: this is a common form of bilateral peripheral corneal degeneration which appears as a grey line encircling the cornea
Degenerative of the vitreous humour
Floaters: these are spots that appears in the visual field and are mainly due to degeneration and increased the fluidity of the vitreous
Degenerative of the lens(cataracts)
Causes
Cataracts maybe congenitally hereditary or acquired
Age-related and degenerative
Changes and demands are the most common cause cataract may follow trauma of the
Pathophysiology
Compaction and stiffening of the central lens material nuclear sclerosis as new layers of cortical fibers continues to proliferate over time
Nursing diagnosis
Disturbed visual sensory perception related to altered sensory reception
Nursing interventions
Use of anticoagulant is withheld to reduce the risk of vetrobulbar hemorrhage
Degenerative of the conjunctiva
Pinguecula: this is a common benign lesion of the conjunctiva consisting of a yellowish white nodule on the bulbar conjunctiva in the area of the palpebral fissure
Pterygium: this is a triangular growth of conjunctival tissue occurring on the nasal bulbar conjunctiva the apex slowly grows towards the cornea where it will interfere with the vision if it reaches the pupillary area
Degenerative of the retina
Age-related macular oedema: this is a leading cause of blindness in the early and it affect central vision
the condition is usually bilateral that affects one eye more than the other
Signs and symptoms: blurred vision and there may also be blind spots resulting in a dark or empty area in the centre of the Field of vision colour vision may be diminished
Retinitis pigmentosa: this is a degenerative hereditary disease which is chronic and progressive degenerative changes may manifest early in life and would occur mainly in the neural epithelial layer of the rod cells
