A 63-year-old male with history of retinal detachment and remote history of bilateral cataract surgery presented to the ED with blurry vision in his right eye. He described sudden-onset visual disturbance “like a curtain dropping” while walking earlier in the day. His vision transiently improved with bending over but would blur again when he stood upright. He denied any ocular trauma, eye pain or swelling, discharge, headache, or other focal neurological complaints. His past medical history included coronary artery disease, diabetes mellitus, hyperlipidemia, and hypertension.\nOn physical exam, pupils were equal and reactive to light bilaterally. Extraocular movements were intact. Visual acuity was 20/100 in the right eye and 20/30 in the left eye. Slit lamp exam of the right eye revealed a deep, quiet anterior chamber, but a lack of pupillary reflection and inability to visualize the retina.\nPoint-of-care ultrasound of the affected eye was performed in the sagittal and transverse anatomic planes using a high-frequency linear transducer. The prosthetic lens was visualized in the posterior chamber with the temporal side haptic still adherent to the lens capsule consistent with an IOL dislocation (, ), whereas an appropriately positioned prosthetic lens would appear as a hyperechoic curvilinear structure within the lens capsule posterior to the iris. The patient was then asked to perform the six cardinal positions of gaze to maximize visualization of the ocular structures. There was no evidence of retinal detachment, vitreous detachment, or vitreous hemorrhage. The case was discussed with his ophthalmologist, and the patient underwent urgent operative repair of the dislocated lens as an outpatient.
A-77-year old woman complained of blurred vision in her left eye. She had undergone cataract surgery with implantation of an IOL 13 years earlier without any complications. She had been diagnosed with presumed sarcoidosis about 15 years earlier, and the mild iritis had been controlled by steroid eyedrops.\nHer BCVA at presentation was 20/30 in the left eyes. The IOP was 15 mmHg and 14 mmHg in the right and left eyes, respectively. Slit-lamp examination revealed no cells in the anterior chamber, but a nasally dislocated in-the-bag IOL was detected (). Slit-lamp examination showed no pseudoexfoliation or vitreous opacities, and ophthalmoscopy showed pigmented chorioretinal atrophy in the periphery. The subfoveal EZ was disrupted in the OCT images.\nShe underwent 27-gauge PPV and the one piece in-the bag PMMA IOL was removed through a 7.5-mm corneal scleral incision without PFCL in September 2017. A CZ70BD IOL (Alcon, Texas, USA) was implanted and fixed with scleral sutures as in the other cases. Thereafter, the PC-IOL was stable (), and the BCVA has remained 20/30 for 2 years without obvious signs of iritis. The peripheral pigmented chorioretinal atrophy and mild macular degeneration could be clearly observed after the surgery (). The visual field was constricted due to the chorioretinal atrophy ().
