1/14. Capsular block syndrome with external blockage of the capsular opening by a ciliary sulcus fixated posterior chamber lens.

    PURPOSE: To report capsular block syndrome with external blockage of the capsular opening by a posterior chamber lens fixated in the ciliary sulcus. METHOD: Case report. RESULTS: In an 89-year-old man who had undergone cataract surgery, a posterior chamber lens was accidentally fixated in the ciliary sulcus after continuous curvilinear capsulohhexis and phacoemulsification/aspiration. The next day, capsular block syndrome was noted along the posterior chamber lens optic, which was blocking the capsular opening from the outside. CONCLUSION: In all previously reported eyes with capsular block syndrome, the posterior chamber lens had been placed inside the lens capsule to block the continuous curvilinear capsulorhexis opening from the inside.

2/14. Capsular block syndrome: A case series.

    Capsular block syndrome (CBS) or capsular bag distension syndrome has been described after cataract removal with in-the-bag placement of a posterior chamber intraocular lens in the presence of an anterior continuous curvilinear capsulorhexis. Features of CBS include shallowing of the anterior chamber and an unexpected myopic overrefraction; occasionally, there is a persistent uveitis. The patient may be mistakenly diagnosed with pupil block glaucoma or endophthalmitis. We report 9 cases of CBS and their initial diagnoses and management. In 1 case, the capsular bag distention and anterior chamber shallowing are illustrated by ultrasound biomicroscopy.

3/14. Capsular block syndrome and pseudoexpulsive hemorrhage.

    Capsular block syndrome (CBS) has been recognized as a cause of immediate or delayed postoperative accumulation of fluid behind an intraocular lens/capsulorhexis complex. Hydrodissection-related rupture of the posterior capsule may be considered a variant of CBS that can manifest intraoperatively. We describe another intraoperative situation related to CBS in which fluid loculation during hydrodissection mimics a threatened expulsive hemorrhage.

4/14. Oval-shaped cornea, lens duplication, and optic nerve hypoplasia associated with myelomeningocele.

    Oval-shaped cornea associated with true lens duplication and separate capsules is a rare anomaly. It can occur as an isolated finding(1,2) or be associated with other ocular and facial maldevelopments.(3-5) We report a novel association of an hourglass cornea, lens duplication, and optic nerve hypoplasia with myelomeningocele in a male infant.

5/14. Capsular block syndrome associated with horizontal jerk nystagmus.

    A 78-year-old cataract patient with horizontal jerk nystagmus had phacoemulsification and intraocular lens (IOL) implantation in the capsular bag with continuous curvilinear capsulorhexis. One week postoperatively, the posterior capsule ballooned posteriorly, the anterior capsule opening was sealed to the IOL optic, and a transparent liquefied substance accumulated between the lens optic and the posterior capsule. The best corrected visual acuity was 0.6 with a myopic shift compared with the refraction after the first day. A neodymium:YAG laser posterior capsulotomy was performed, and the capsular block syndrome (CBS) resolved. The results confirm the experimental model proposed by Zacharias suggesting that saccadic eye movements contribute to CBS under certain anatomic conditions.

6/14. Capsular block syndrome in a case with excessive cortical remnants.

    Ten days after cataract extraction with phacoemulsification and in-the-bag acrylic intraocular lens implantation, capsular block syndrome developed in the right eye of a 62-year-old man. Aspiration of the swollen cortical remnants resulted in resolution of the capsular block.

7/14. Management of lens-iris diaphragm retropulsion syndrome during phacoemulsification.

    Lens-iris diaphragm retropulsion syndrome (LIDRS) occurs more often than recognized during small-incision phacoemulsification. This syndrome requires an infusion of fluid into the anterior chamber and is characterized by posterior displacement of the lens-iris diaphragm, marked deepening of the anterior chamber, posterior iris bowing, pupil dilation, and often significant patient discomfort. Using microendoscopy, we have observed that LIDRS is essentially a reverse pupillary block. We describe a surgical technique to mechanically break the iridocapsular block to restore normal chamber depth, relieve patient discomfort, and allow the surgeon to proceed safely with phacoemulsification.

8/14. Assessment of capsular block syndrome with anterior segment optical coherence tomography.

    A 59-year-old woman developed progressive, moderate myopia 1 year after routine phacoemulsification and insertion of a soft posterior chamber intraocular lens (IOL). After biomicroscopy, late capsular block was diagnosed and treated with a neodymium:YAG laser posterior capsulotomy. The myopia disappeared immediately. This case was illustrated using optical coherence tomography developed for the anterior segment. After capsulotomy, the IOL moved backward by 448 microm, corresponding to -0.75 diopter of induced myopia.

9/14. Late postoperative capsular block syndrome: entrapment of liquefied after-cataract by capsular bend.

    We report a case of capsular bend-related entrapment of liquefied after-cataract that resulted in late postoperative capsular block syndrome in a 56-year-old man. Slitlamp examination showed a capsular bend formation at the square edge of the optic. Superiorly, leakage in the capsular bend resulted in fluid extending into Soemmering's ring, although communication with the anterior chamber was limited by the capsular bend. Fluid was seen between the lens and posterior capsule.
