True or False: Latanoprost tends to produce the least hyperemia among prostaglandin analogs.

• A. False
• B. True
• C. Not sure
• D. Sometimes

Answer: (B)

Hyperemia is a common ocular surface side effect of prostaglandin analogs used to reduce intraocular pressure. The degree of redness varies by agent because of differences in how strongly each drug promotes conjunctival vessel dilation. Latanoprost generally produces the least conjunctival hyperemia among the commonly used prostaglandin analogs, making the statement true. Bimatoprost and travoprost tend to cause more redness, reflecting a higher tendency to dilate conjunctival vessels with those agents. Individual responses vary, but the overall pattern supports latanoprost as the least hyperemic option among these medications. The other options don’t fit this general trend.
