Abstract Details
Purpose:
To describe the management of an unusual case of traumatic total aniridia in a patient with multifocal intraocular lens.
Setting:
Institut Oftalmologic Creu Groga, Hospital de Granollers
Methods:
A sixty-five year old woman, pseudophaquic with bilateral multifocal intraocular lens (IOL) presented to the ophthalmology department after an ocular traumatism in her left eye (LE). Her visual acuity (VA) in LE was of light perception and she presented with diffuse hyphema in the anterior chamber, which did not allow for exploring the rest of the intraocular structures. Her intraocular pressure (IOP) was of 20 mmHg. An orbital computed tomography ruled out bone fracture and an ocular echography confirmed globe integrity and showed plenty of vitreous blood clots and attached retina. Topical corticosteroids, mydriatics and hypotensive drops were started.
Results:
After one week the total absence of iris was detected, with well-centered IOL. IOP increased to 34 mmHg, which required the addition of oral acetazolamide. Two months later, her VA was of 0.8 without refraction, she had traumatic aniridia of 360 degrees, IOP of 14 with brinzolamide plus timolol, and few vitreous hematic traces. Three months after the trauma, she presented with good IOP control without hypotensive treatment and a cosmetic contact lens was adapted to avoid photophobia, reaching VA of 1.0 with great functional and cosmetic outcomes.
Conclusions:
In pseudophakic eyes, an acute IOP rise after a blunt trauma can lead to a transitory opening of the surgical incisions, causing an abrupt decompression of the eye producing iris root disinsertion and iris expulsion. However, it would act at the same time as a release valve, avoiding globe rupture or IOL dislocation. Aniridia can cause worsening of VA and visual quality which can be solved with a cosmetic contact lens thus maintaining the benefits from the multifocal IOL.
