The definition of primary ocular tuberculosis (TB) has varied: some authors have used it to describe ocular disease in the absence of systemic involvement, while others take it to describe disease in which the eye is the initial port of entry of the mycobacterium into the body.
Secondary ocular tuberculosis is defined as ocular involvement as a result of seeding by hematogenous spread from a distant site, or direct invasion from adjacent areas, like the sinus or cranial cavity.
Ocular tuberculosis manifestations are the same as in immunocompetent patients, and disseminated choroiditis is the most commonly cited manifestation.

 Encyclopedia - Ocular Hypertension   (Site not responding. Last check: 2007-11-01)
Ocular hypertension occurs when the intraocular pressure in your eyes is above the normal range, but it has not yet affected your vision or damaged the structure of your eyes.
Because ocular hypertension has no outward symptoms, people over the age of 40 and those in a high-risk category for glaucoma should have their pressure checked every year.
Although ocular hypertension in itself is not sight threatening, if pressure within the eye builds to the point where it damages the optic nerve (glaucoma), eyesight can be permanently damaged.

 NOAH — Ocular Albinism

With ocular albinism, the color of the iris of the eye may vary from blue to green or even brown, and sometimes darkens with age.
With ocular albinism, the fovea does not develop completely, presumably because melanin pigment is needed for the growth processes that normally occur before birth.

Ocular hypertension and glaucoma can only be diagnosed through a series of tests, including a measurement of your eye’s pressure and an examination of the inner structures of the eyes.
