What is the abbreviation for the Outer Plexiform Layer?

• A. OPE
• B. OPL
• C. OPL-1
• D. OPR

Answer: (B)

In retinal anatomy, the Outer Plexiform Layer is the synaptic zone where photoreceptors connect with bipolar and horizontal cells. The standard abbreviation used in textbooks and OCT literature for this layer is OPL, which is why that option is the correct one. Other abbreviations don’t reflect the conventional name for this layer (for example, those alternatives would imply different terms or aren’t used in standard retina nomenclature). On OCT, the OPL sits between the Outer Nuclear Layer and the inner retinal layers, marking the site of photoreceptor synapses.
