Presentation
Presentation : these variably present from early childhood (especially lymphangiomas) to adulthood. Varices present with intermittent proptosis (evident in the Valsalva manoeuvre) visible lesions in the eyelid. [patient.info]
The disease often presents itself differently in each patient and is commonly difficult to diagnose for this reason. Rheumatologists can diagnose the disease in patients who have presented with similar symptoms for many months. [rebuildyourvision.com]
Each patient presented with congenital nystagmus and was diagnosed with isolated absence of the optic chiasm on the basis of neuroimaging. [ajnr.org]

Pigment clumps in the form of bone spicules in a paravenous distribution appear as young as 1 year of age and may be present congenitally. [disorders.eyes.arizona.edu]

However, it was not until 1854 that British physician John Nottingham (1801–1856) clearly described keratoconus and distinguished it from other ectasias of the cornea. [12] Nottingham reported the cases of "conical cornea" that had come to his attention [en.wikipedia.org]

The classic feature is optic nerve dysfunction and visual impairment out of proportion with the degree of proptosis. Some patients are observed (some tumours have an indolent course) but most require surgical excision radiotherapy. [patient.info]
Repeated and prolonged infection causes permanent visual impairment and blindness. Trachoma is spread through direct contact with secretions from the eyes, eyelids, or nose of an infected person. [tsbvi.edu]

Prognosis
There may be some benefit in those with tumor-related (58) or traumatic VI nerve palsies (51, 59) (60), which do not have as good a natural prognosis. [neuroophthalmology.ca]
These scotomas are smaller than the size of the MRNF patch would suggest. [4] [18] Visual acuity and prognosis depends on the severity of ocular complications or associated syndromes (Table 1). [eyewiki.aao.org]

Etiology
Many older ophthalmologists adhered to the hypothesis that excessive close or abnormal use of the eyes was the cause of myopic visual changes, but some early workers, in particular Steiger (1913), supported a genetic etiology. [questia.com]
Reported cases in the literature of angle closure in the setting of high myopia (excluding those due to inflammation or contracting membranes) include a number of possible etiologies such as primary pupillary block, plateau iris, malignant glaucoma after [glaucomatoday.com]
Certainly some diagnoses to be considered when looking at corneal haze include anterior basement membrane dystrophy, Fuchs’ endothelial dystrophy, posterior polymorphous membranous dystrophy, as well as a variety of infectious etiologies. [healio.com]

Pathophysiology
The pathophysiologic basis for decussation of retinal axons is an area of active research. Pathfinding of retinal axons at the optic chiasm is incompletely understood at this time. [ajnr.org]
Decreased vision - visual acuity may be impaired by: Direct optic nerve involvement due to the pathophysiology. Distortion of the macula by a lesion pushing in behind the globe. Exposure keratopathy (see above) can also affect the visual acuity. [patient.info]
The pathophysiology of isolated high myopia remains unknown. Besides heredity, the trait depends on environmental factors and, moreover, the genetic component is also complex. [jmg.bmj.com]
