Outcome Measures
Primary Outcomes (1)
Although the treatment of peripheral retinal degenerations with infrared laser to be well tolerated by the majority of the patients, it is more painful than with green wavelength.
Interventions
Each patient had one eye treated with infrared laser (diode, 810nm wavelength) and the other eye treated with green laser (frequency-doubled solid state laser, diode-pumped, with 532-nm wavelength
Eligibility Criteria
You may qualify if:
- horseshoe tears and dialyses, besides operculated holes and lattice degeneration in symptomatic patients (photopsias) or with history of retinal disease
You may not qualify if:
- severe liver disease, pregnancy, patients on regular analgesics, previous laser photocoagulation, and age less than 18 years old.
