Abstract Details



Purpose:

The retinal pigment epithelium (RPE) plays a significant role in repairing the outer and inner blood-retinal barrier regrardless of the type and location of laser application. Our aim is to study the effect of transscleral subthreshold micropulse diode laser in treatment of diabetic retinopathy

Setting:

This study was done in the ophthalmology department of Saudi German Hospital, Jeddah

Methods:

This study included 46 eyes of 34 patients who had diabetic macular edema and or proliferative diabetic retinopathy. panties were divided into 2 groups Group 1 has macular edema thickness less than 400 um. Group 2 has proliferative diabetic retinopathy with vitreous haemorrhage. Trans-scleral micropulse diode laser treatment was given to the periphery of the retina laser sitting ranged from 1 to 3 in the first group and up to 5 sittings in the second group. The same laser parameters were used for each patient. Only the number of laser shots varied between patients. Before laser treatment and in follow up, visual acuity, OCT, coloured fundus photo and fluorescein angiography were done.

Results:

Patients follow up ranged between one months to one year. Visual acuity were improved in 68% of treated eyes in Group 1, and in 84% of eyes in Group 2. Statically significant reduction of macular edema were in 70% of eyes in Group 1. total disapearance of vitreous haemorrhage and reductiona of diabetic retinopathy were observed in 80% of eyes in Group 2. No adverse laser events occurred, no laser lesions were detectable clinically or angiographically after treatment.

Conclusions:

Transscleral subthreshold micro pulse diode laser treatment of diabetic macular edema and proliferative diabetic retinopathy is an easy new technique, effective and safe treatment way.
