Application of transpupillary thermotherapy in a patient with asteroid hyalosis and premacular hemorrhage.
A 70-year-old woman with long-term poor vision was found to have unilateral massive premacular hemorrhage and asteroid hyalosis. Transpupillary thermotherapy (TTT) was applied sequentially to the vitreous in four separate spots, covering the area of the asteroid hyalosis and hemorrhage. Outcome measures included visual acuity, biomicroscopic appearance, ultrasonography, and fluorescein angiography. Significant resolution of the hemorrhage was observed 3 months after TTT, with visual acuity improvement from counting fingers at 25 cm to 20/60. There were no complications noted during the procedure or during follow-up. The long-term safety measures and visual prognosis following TTT for resolution of the vitreous impurities remain to be evaluated, but the procedure may be effective for treating premacular hemorrhage and asteroid hyalosis.
