“…Scheimpflug imaging in these cases showed change in the anterior chamber depth and also distention of the capsular bag due to accumulation of fluid in the retrolenticular space. Previous reports also supported our imaging findings that ultra-late presentation usually doesn't show significant change in the refraction or the anterior chamber depth clinically [7].…”

“…Ultra-late onset CBDS is recently described term that presents after 7 years of cataract surgery lacking the classical features of CBDS i.e. shallow anterior chamber, elevated intraocular pressure, and induced myopia from the anterior shift of the intraocular lens [2,7]. Literature shows very few cases that were detected after such a long duration; may be asymptomatic in nature or clinically difficult to diagnose but without any characteristic documentation.…”

“…In the early post-operative period, detection of CBDS is easier as patient presents with clinical signs like reduced vision and myopic shift with forward displacement of the posterior chamber intraocular lens (IOL) and accumulation of retrolenticular fluid [4][5][6]. Zhu described characteristic Scheimpflug imaging in 3 ultra-late onset CBDS cases that presented after 7 years of phacoemulsification surgery [7]. In our case series, we documented the characteristics of ultra-late onset CBDS and analyzed their risk factors.…”

Background: To provide insights into the characteristic of ultra-late onset capsular bag distension syndrome (CBDS) after phacoemulsification. Design: An interventional, retrospective case series at a tertiary care institute. Participants: 5 Post-cataract surgery patients who presented with the retrolenticular fluid collection. Methods: This is an interventional, retrospective case series of 5 cases who presented with clinical signs of ultralate CBDS>7 years after uneventful phacoemulsification with in-the-bag posterior chamber intraocular lens implantation at a tertiary care institute. Scheimpflug imaging was used in all cases in addition to slit lamp biomicroscopic examination to assess and diagnose the condition. Neodymium:Yttrium Aluminium Garnet (Nd:YAG) posterior capsulotomy was performed in all to treat the condition. Main outcome measure: Results: All 5 patients presented with a milky fluid collection within the distended capsular bag without raised intraocular pressure or a shallow anterior chamber. Scheimpflug imaging confirmed the diagnosis in all cases and all eyes revealed a hyper-reflective space between the intraocular lens optic and the posterior capsule. Nd:YAG posterior capsulotomy was performed in all patients, with resolution of fluid and improvement of visual acuity. Conclusion: Our case series showed that Scheimpflug imaging is a useful modality to diagnose ultra-late onset CBDS and to differentiate this condition from intraocular lens opacification and posterior capsule opacification (PCO). Nd:YAG posterior capsulotomy proved to be successful treatment for ultra-late CBDS with no significant change in biometric or refractive parameters.

“…Additionally, residual lens epithelial cells and posterior capsule opacification were also noted in previous reports [10]. Diagnosis of late-onset postoperative CBS depends on the identifying of milky-white fluids with slit lamp examination and Scheimpflug images [4]. When the liquefied substance is difficult to identify as shown in case 2, misalignment of iris and IOL shown in virtual eye simulation implies unevenly distributed pressure behind IOL and assists the diagnosis (Fig.…”

“…Possible treatments include neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy or surgical lysis of adhesions [3]. Scheimpflug imaging has shown advantages in detecting changes in the anterior segment and peri-IOL region including the posterior capsule caused by CBS [4,5]. We present clinical findings of three cases of postoperative CBS diagnosed with the aid of Pentacam Scheimpflug imaging and virtual eye simulation.…”

Objective: To demonstrate the findings of three consecutive cases of postoperative Capsular Block Syndrome (CBS) diagnosed with the aid of Pentacam virtual eye simulation images. Methods: Observational case series report. Three patients underwent uneventful cataract removal and presented with blurry vision ranging from 4 days to 5 years after the surgeries were performed. Results: In a case of early-onset postoperative CBS, virtual eye simulation images clearly revealed a reduced posterior chamber depth caused by the accumulation of transparent fluid in the area between the intraocular lens and the posterior capsule. In two cases of late-onset postoperative CBS, virtual eye simulation images better visualized the alignment between intraocular lens (IOL) and iris than slit lamp examination and Schiemflug images. All three of the cases underwent neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy, and their capsular bag distensions were resolved immediately. The patients with misalignments between IOL and iris experienced more improvement in best-corrected visual acuity as opposed to the one who did not. Conclusion: Virtual eye simulation is found to be a useful way in visualizing misalignment between IOL and iris and assisting diagnoses of both early- and late-onset postoperative capsular block syndrome.
