NCT03672656

Brief Summary

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).

Outcome Measures

Primary Outcomes (2)

  • 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

    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)

    1 day

Secondary Outcomes (1)

  • Satisfaction assessed by the VAS
