Thirty eyes of three insulin dependent and twenty six noninsulin dependent diabetic Iraqi patients were included. The study involved twenty six males, threefemales and followed for one year. Their ages were ranging between 36- 59 years, all of them frompatients attending ophthalmic out-patient department in the medical city in the period between January2005 and June 2006. Eyes divided in to two groups (fifteen eyes in each group) and the diseaseseverity was taken into account. The first group treated with 0.1 second and second group with 0.2second pulse duration.Results: In group (1) improvement of V.A occurred in 19.99% (Statistically significant) and 60%(Statistically significant) in group (2). There was stabilization 80% (Statistically insignificant) ingroup (1) and 33.33% Stabilization (Statistically significant) in group (2), while worsening only ingroup (2) 6.67%(Statistically insignificant).Conclusion: The frequency doubled Nd:YAG laser is effective in controlling diabetic macularoedema when applied in focal treatment. The setting of 100μm 0.2sec., pulse exposure time showmore improvement in V.A. than 100μm 0.1sec.Keywords: Laser, Focal, Photocoagulation.
