Talk:Macula

reorganise?

this article reads a bit back to front. one of the first things should be the function of the macula, i get the impression from the article that its function is as a sunblock :P

this sentence : "Structures in the macula are specialized for high acuity vision. Within the macula are the fovea and foveola which contain a high density of cones (photoreceptors with high acuity)" should go higher and get expanded a little? i dont have the expertise im afraid. —Preceding unsigned comment added by 94.173.7.118 (talk) 22:40, 12 December 2010 (UTC)

They would be discussed in the article "Macular degeneration". AED 06:19, 19 August 2005 (UTC)

Remove word "severe"?

Article describes macular degeneration as a "severe" disease. My instinct is to remove the word as being both unnecessary (loss of vision is by its nature a severe problem) and misleading (as there are mild and slow-progressing cases of macular degeneration). Any thoughts? Pheidias 21:56, 23 January 2007 (UTC)

Comment

Yes Perhaps a distinction should be made between macular degeneration and a macular hole. They aren't the same thing. —Preceding unsigned comment added by 82.8.155.173 (talk) 21:41, 10 February 2009 (UTC)

Relation to Optic Disk

The macula lutea is 3mm lateral to the optic disc. —Preceding unsigned comment added by Avkrules (talk • contribs) 03:50, 7 July 2010 (UTC)

Since the article says the macula lutea is itself 5 mm wide, and optic disk also has a diameter, what is your distance based upon? Center of macula to edge of disk? Center-to-center? Edge-to-edge? SBHarris 23:34, 12 December 2010 (UTC)

Wrong color

The macula is a dark spot on the retina. It only appears yellow in a dissected eyeball, or when viewed with an ophthalmoscope, which filters out red light. For 200 years it was thought that the macula appears only after death because no one had seen it in a living eye. (here) Zyxwv99 (talk) 15:15, 4 November 2014 (UTC)

British or American English?

The word "colour" has been there for many years. However, the article as a whole looks like it has been primarily in American English since the beginning, just based on my own subjective impression of the overall style. Maybe we could take an informal poll, or at least solicit comments. Zyxwv99 (talk) 14:32, 8 November 2014 (UTC)

Ambiguity in the first sentence.

I understand that the macula is located "near the center of the retina". But, for goodness' sake, in which direction? The retina is a layer that exists in three-dimensional space. So "near the center" can mean that the macula is a part of the retina or that it exists at a perpendicular distance from the retina? The picture suggests the latter. Could you please be more precise and explain it, not here but in the content of the article? 85.193.250.200 (talk) 16:53, 22 April 2020 (UTC)

Fair question. The macula is part of the retina, its central part. Its center is 1.5 mm away from the retina center, i.e. from the optic axis. I added the distance in the section "Structure" (not in the introduction).

The problem arises from the graph, a typical textbook hoax: Graphically nice but grossly misleading. It is obviously intended to show a central cross section (telling from the lens and iris), but in such a section the macula would not be visible. I will add a note in the legend.
