Capsular bag distension syndrome (CBDS) is a rare complication of cataract surgery within the bag intraocular lens (IOL) implantation. CBDS is characterized by the build-up of the turbid fluid between the IOL and the posterior capsule. It is also known as capsular block syndrome, capsulorhexis block syndrome, or capsular bag hyperdistention. It later leads to decline in the visual acuity of the patient.
| Epidemiology|| |
Literature review shows the incidence of CBDS to be 0.73% in patients who undergo phacoemulsification with in-the-bag IOL implantation. It has also been reported that CBDS can present from weeks to even years after the cataract surgery.
| Pathophysiology|| |
Depending on the time of onset, CBDS can be classified into three types, namely, intraoperative, early postoperative, and late postoperative. Intraoperative CBDS develops at the time of surgery and is believed to occur as a result of high irrigation pressure during the hydrodissection to separate the cataractous lens from the capsular bag. Pressure built up may lead to posterior capsular rupture. Early postoperative CBDS is believed to occur due to retained viscoelastic material behind the IOL. Late CBDS cause is unknown but is assumed to be caused due to occlusion of the capsulotomy by the optic of the IOL which prevents the free flow of fluid through this aperture.
| Diagnosis|| |
The patient presents with the complaint of diminution of vision. There may also be increased intraocular pressure due to anterior displacement of the lens-iris diaphragm. Slit-lamp examination (SLE) shows the presence of fluid between the lens and the posterior lens capsule. The fluid may be clear or turbid. Anterior segment optical coherence tomography and ultrasound biomicroscopy can help in the confirmation of the diagnosis and also help in the diagnosis of cases with minimal fluid, which may be missed on SLE. Scheimpflug imaging may be clinically useful to document morphologic changes in the anterior segment in CBDS.,
| Case Report|| |
A 56-year-old-male patient underwent phacoemulsification with posterior chamber IOL implantation in the left eye (OS). The patient complained of diminution of vision in the OS at 2-year follow-up. The best-corrected visual acuity (BCVA) was 20/40 OS and 20/20 in the right eye. SLE and Scheimpflug imaging showed the presence of turbid fluid between IOL and posterior capsule, suggestive of CBDS. The patient was successfully managed with neodymium-doped yttrium aluminum garnet capsulotomy and the BCVA improved to 20/20 [Figure 1]a, [Figure 1]b, [Figure 1]c].
