Bilateral spontaneous anterior lens dislocation in a retinitis pigmentosa patient.

Kwon YA, Bae SH, Sohn YH - Korean J Ophthalmol (2007)

Bottom Line: A 45-year-old male with RP presented with elevated intraocular pressure (IOP) in the right eye and was treated with laser iridotomy (LI).Two years later, the same episode occurred in his left eye and a similar treatment was done.Surgery was successful in both eyes.

ABSTRACT

Purpose: To report a case of bilateral spontaneous anterior lens dislocation associated with retinitis pigmentosa (RP).

Methods: A 45-year-old male with RP presented with elevated intraocular pressure (IOP) in the right eye and was treated with laser iridotomy (LI). After LI, complete crystalline lens dislocation into the anterior chamber occurred. Surgical intervention, including anterior vitrectomy, intracapsular cataract extraction (ICCE), and IOL scleral fixation was performed. Two years later, the same episode occurred in his left eye and a similar treatment was done.

Results: Surgery was successful in both eyes.

Conclusions: This is the first report of bilateral spontaneous anterior lens dislocation in a RP patient.

Figure 2: Visual field of the right (A) and left (B) eye. Extensive peripheral field defect is noted (central 10°). Visual field using the Humphrey Visual Field Analyzer (model 750, Humphrey Instruments, Inc, Dublin, California; C24-2 program).

Mentions: All medications were given twice during the night. One day after treatment right eye IOP decreased to 50 mmHg, the cornea became clear, and the central anterior chamber depth remained 2 CT. Therefore, LI was done; 3 hours later IOP decreased to 20 mmHg. Six days later, the cornea was clear, the anterior chamber was deep and clear bilaterally, and the right eye LI opening was patent. Using the Humphrey Visual Field (model 750, Humphrey Instruments, Inc, Dublin, California; C24-2 program) examination showed narrowing to central 10° in both eyes (Fig. 2), and electroretinogram findings were prolonged in a and b amplitudes (Fig. 3).
