**Question:** The type of synechiae in iris bombe is –
A. Intraocular synechiae
B. Corneal synechiae
C. Pupillary synechiae
D. Iris-lens synechiae
**Core Concept:** Iris bombe is a complication of uncontrolled glaucoma, characterized by the formation of dense, fibrous bands between the iris and other intraocular structures.
**Why the Correct Answer is Right:**
D. Iris-lens synechiae is the correct answer because iris bombe results from the progression of synechiae, which are fibrous connections between ocular tissues. In this case, the synechiae form between the iris and the lens, causing obstruction of the pupil and leading to glaucoma exacerbation.
**Why Each Wrong Option is Incorrect:**
A. Intraocular synechiae (A) is incorrect because it refers to synechiae within the eye, not those between the iris and lens, as in iris bombe.
B. Corneal synechiae (B) is incorrect because it refers to synechiae between the cornea and other ocular structures, which is different from the iris-lens synechiae in iris bombe.
C. Pupillary synechiae (C) is incorrect because it refers to synechiae involving the pupil, not the iris and lens, which are the primary affected structures in iris bombe.
**Clinical Pearl / High-Yield Fact:**
Understanding the type of synechiae in iris bombe is crucial for proper diagnosis and management. In iris bombe, the formation of iris-lens synechiae leads to pupillary obstruction, increased intraocular pressure, and vision impairment. Timely intervention is essential to prevent further ocular damage and preserve vision.
