It is not clear whether the reduction of corneal endothelial cell numbers and loss of function is secondary to the Descemet's membrane changes, occurs independently or is a mixture of both.
Generalised involutional degeneration of the cornea includes decreased corneal thickness, increased rigidity, thickening of Descemet's membrane, and reduction of endothelial cells.
However, in this condition there is no photophobia or corneal swelling, no break in Descemet's membrane, no abnormality detectable in the anterior chamber angle, no cupping of the optic disc, and no significant increase in IOP.
Corneal oedema is initially manifest in the posterior stroma adjacent to Descemet's membrane and just behind Bowman's membrane, causing a fine grey haze best seen with sclerotic scatter (see Figure 2).
The new layer that has been discovered is located at the back of the cornea between the corneal stroma and Descemet's membrane.
The eye is uniquely affected, as copper accumulates in Descemet's membrane of the corneal limbus, resulting in KF rings (Figure), and in the lens, resulting in sunflower cataracts.
Twelve hours later, vision had improved to 6/9 and 6/12 and folding of Descemet's membrane had lessened.
