[Observation on clinical effects of panretinal coagulation for diabetic retinopathy].

OBJECTIVE

Observing and evaluating the clinical effects of panretinal photocoagulation with Argon laser for diabetic retinopathy.

METHODS

According to the results of fundus fluorescence angiography (FFA), panretinal photocoagulation with Argon laser were performed on 143 eyes (87 cases) of diabetic retinopathy, including 79 eyes with preproliferative diabetic retinopathy eyes with proliferative diabetic retinopathy (PPDR), 64 (PDR). Examination about FFA, visual acuity and fundus condition were carried out before laser treatment and 3 months after photocoagulation. The regular following up lasted for 6 months to 2 years.

RESULTS

Laser photocoagulation proved effective in 122 eyes (85.31%) with diabetic retinopathy, including 73 eyes (92.41%) with PPDR, 49 eyes (76.56%) with PDR. The visual acuity were improved in 32 eyes (23.38%), no changes in 87 eyes (60. 84%), decrease in 24 eyes (16.78%). No complication was found in all patients.

CONCLUSIONS

Panretinal photocoagulation with Argon laser is a safe and effective method to control the condition of diabetic retinopathy.
