Abstract Details

Purpose:

We aimed to present a case of cataract developing after night vision binoculars, a rare condition.

Setting:

Yuzuncu Yil University, Department of Ophthalmology

Methods:

Case report

Results:

A 43-year-old policeman applied to our clinic recently due to decreased visual acuity in his right eye. The patient noted that he had been using night vision binoculars for about 20 years with his right eye in history. The best corrected visual acuity(BCVA) was 0.15 in right eye and 1.0 in the left. Anterior subcapsular cataract was observed in anterior segment examination in the right eye and was normal in the left. Fundus examinations were normal bilaterally. Patient’s right eye underwent phacoemulsification and intraocular lens implantation surgery. BCVA was 1.0 in the right eye in postoperative 2nd month follow-up.

Conclusions:

Although rare, ionizing radiation such as X-rays, gamma-rays, beta-rays, and neutrons may cause cataracts due to its effect on the germinal membrane at the lens aperture. This process can take 4-10 years depending on the degree of exposure. Patients using special devices, such as night vision binoculars, should consult an eye doctor at least once a year after using the device.
