Purpose: To evaluate the clinical efficiency, safety and painfulness of retinal laser photocoagulation employing a pattern scanning laser system Pascal given in a single-session versus conventional laser multiple-session treatment of the same patient with diabetic retinopathy. Methods: The cohort included 60 eyes in 30 patients treated at the Ophthalmology Clinic, Faculty Hospital Ostrava, from 2008 to 2013. Panretinal laser coagulation was performed on one eye using the multispot panretinal photocoagulation given in a single-session system Pascal (SSP) (OptiMedica, Santa Clara, California). On the other eye laser treatment was carried out by the classic conventional multiple-session method (MSM).

pattern scanning laser system Pascal given in a single-session
conventional laser multiple-session treatment
Clinical efficiency - progression of diabetic retinopathy, scored by calculating of microaneurisms and intraretinal hemorrhages
progression of diabetic retinopathy after pattern PASCAL laser versus conventional laser. Each item is scored by calculating of microaneurisms and intraretinal hemorrhages
Time frame: 1 year
Pain assessed by NRS
painfulness of pattern PASCAL laser versus conventional laser Each item is scored 0-10 (0 - no pain, 10 - pain as bad as can be)
Time frame: 1 day
Satisfaction assessed by the VAS
subjective satisfaction of the patient on dog 0 to 4 0 - not satisfied, 4 - very satisfied after pattern PASCAL laser versus conventional laser
Time frame: 1 day
