Table 2.

Intensity of Immunolabeling for M1 to M5 in Ciliary Muscle, Iris and Retina as Compared to Control Sections With Matched Intensity (See Supplementary Figs.)

Muscarinic Receptor Subtype	Ocular Tissue
Muscarinic Receptor Subtype	Ciliary Muscle	Iris	Retina
M1	++	++	+
M1	++	++	PRL, OPL, IPL
M2	++	+	++
M2	++	+	PRL, OPL, NFL
M3	+++	+++	++
M3	+++	+++	IPL, OPL, NFL
M4	++	++	+
M4	++	++	IPL, OPL, NFL
M5	+++	+	+
			OPL, IPL
			+++
			NFL

Distribution of staining in the retina is shown. PRL, photoreceptor layer; NFL, nerve fiber layer; +++, highest specific staining; +, lowest specific staining.
