Therapeutic effects of laser photocoagulation and/or vitrectomy in Eales' disease.
OBJECTIVE
To determine visual outcomes and regression of retinal neovascularization following laser photocoagulation and/or vitrectomy in eyes with Eales' disease.


METHODS
In a retrospective noncomparative study, the authors reviewed the existing data of 67 eyes of 54 patients with a diagnosis of Eales' disease who had undergone laser photocoagulation and/or vitrectomy based on their clinical presentations. Main outcome measures were visual acuity changes and regression of retinal neovascularization of the eyes following treatment.


RESULTS
Both laser therapy and vitrectomy improved visual acuity and induced regression of retinal neovascularization. Forty-three eyes had undergone laser therapy; their rate of visual acuity 320/30 improved from 53% before treatment to 60% after treatment. Twenty-four eyes had undergone vitrectomy; rate of visual acuity 320/30 improved from 13% before surgery to 38% after surgery. In eyes that had undergone laser therapy, additional laser therapy controlled recurrent neovascularization in 47% of the eyes, but ultimately, 12% of them required vitrectomy. In the primary vitrectomized group, additional required treatment was repeat vitrectomy in 21%, and/or laser therapy in 29% of the eyes.


CONCLUSIONS
Although laser photocoagulation should be the first line of treatment in Eales' disease, it cannot always induce regression of retinal neovascularization. In such cases vitrectomy may further enhance therapeutic success.
