“…It is the most common cause of lens luxation-subluxation, accounting for about 53% of all cases [ 7 ]. Blunt ocular trauma compresses the eye in the anterior-posterior direction expanding the eye and stretching the zonules [ 8 ]. The direction of dislocation determines management.…”

Anterior megalophthalmos is a rare, bilateral, nonprogressive, hereditary, congenital disorder characterized by the enlargement of all anterior segment structures of the eye, with megalocornea, iris atrophy, and zonular abnormalities. We report a case of an 8-year-old male who presented to the emergency department with a history of visual loss after a blunt ocular trauma to the left eye. The patient presented with markedly enlarged corneas and deepened anterior chambers bilaterally. Best-corrected visual acuity (BCVA) was hand motion in the left eye. An additional examination revealed multiple anterior segment abnormalities, leading to the diagnosis of megalophthalmos and lens dislocation in the anterior chamber. The patient underwent a lensectomy and anterior vitrectomy in the left eye. At six months postoperatively, the BCVA was 20/200 in the left eye. Lens dislocation in patients with megalocornea is rare. Cataract surgery in these patients requires attention to the zonular abnormalities and lens enlargement, resulting in increased rates of intraoperative and postoperative complications. Ophthalmologists should be able to diagnose this rare disorder and manage the associations and complications.

“…Lens dislocation alone is caused by multifactorial factors, including some kind of congenital abnormalities, such as Marfan syndrome, Weill-Marchesani syndrome, and homocystinuria, zonules-related eye disease, such as high myopia and pseudoexfoliation syndrome, iatrogenic condition, along with blunt trauma. [11], [12] A study reported that the major cause of lens dislocation was trauma. [12] Blunt trauma causes compression of the eye antero-posteriorly which then cause an expansion of the eye in several directions, laterally, superiorly, and inferiorly.…”

Introduction: Ocular trauma is an important cause of unilateral visual impairment and blindness. Among several agents of ocular trauma, blunt trauma is the most common and can lead to secondary glaucoma. Secondary glaucoma due to blunt ocular trauma can be unnoticed and undetected until the formation of glaucomatous optic neuropathy (GON) occurs. This case might not be neglected. Delay in treatment can lead to the progression of GON. Case Presentation: A 68-year-old woman presented to the outpatient clinic in Undaan Eye Hospital complaining of decreased vision and pain in the left eye after blunt trauma to the eye. Her left eye vision was limited to detecting hand motions (1/300) and the intraocular pressure (IOP) was 37.8 mmHg. On the slit lamp biomicroscopic examination, the left pupil was mid-dilated, lens opacification and phacodenesis were detected. The cup-to-disc ratio (CDR) of the left eye increased (0.8-0.9) through the funduscopic examination. Secondary glaucoma due to subluxated lens was diagnosed for the left eye. The patient was given topical and oral antiglaucoma medications and was evaluated after one week of drug use. Since the IOP remained elevated after medical therapy, left eye trabeculectomy was conducted. Bleb was formed postoperatively and the IOP was getting normal without oral glaucoma medications. Conclusion: Blunt ocular trauma can lead to secondary glaucoma. Thorough examinations and immediate treatments should be conducted to preserve patient’s vision and prevent further optic nerve damage.

“…Patients may present with pain in the affected eye, blurry vision, or vision loss [ 3 ]. The treatment of lens dislocation depends on the direction of lens displacement [ 3 , 12 ]. Anterior lens dislocations require emergent surgical correction if causing acute angle-closure glaucoma, whereas posterior lens dislocations can be managed by ophthalmology on an urgent basis [ 3 , 10 , 12 ].…”

“…The treatment of lens dislocation depends on the direction of lens displacement [ 3 , 12 ]. Anterior lens dislocations require emergent surgical correction if causing acute angle-closure glaucoma, whereas posterior lens dislocations can be managed by ophthalmology on an urgent basis [ 3 , 10 , 12 ]. Failure of conservative management or development of complications such as uveitis or glaucoma indicates the need for surgical correction of a posterior lens dislocation [ 3 , 12 ].…”

“…Ocular point-of-care ultrasound (POCUS) offers an accurate bedside modality for the EP to diagnose several eye emergencies [ 4 - 7 ]. Previous reports have highlighted the utility of ocular POCUS to recognize lens dislocation after acute blunt eye trauma [ 8 - 12 ]. This case report describes the diagnosis of a traumatic lens dislocation with EP-performed ocular POCUS in a patient with blurry vision over several months.…”
