Lenticular burns following PASCAL photocoagulation

Serous retinal detachment following panretinal photocoagulation (PRP) using Pattern Scan Laser (PASCAL) photocoagulator

OBJECTIVE To report a case of serous retinal detachment after Pattern Scan Laser (PASCAL) treatment in a diabetic woman. METHODS A 34-year-old diabetic woman presented with florid diabetic retinopathy after a miscarriage during the 20(th) week of pregnancy. Her Best Corrected Visual Acuity (BCVA) was 20/40 right eye (OD) and 20/30 left eye (OS). Fundus exam showed multiple microaneurysms, lar...

MAPASS report 2 photocoagulation : Manchester Pascal Study , ms single - spot panretinal 100 ms multi - spot and Pain responses of Pascal

Aims To evaluate pain responses following Pascal 20 ms multi-spot and 100 ms single-spot panretinal photocoagulation (PRP). Methods Single-centre randomised clinical trial. 40 eyes of 24 patients with treatment-naive proliferative diabetic retinopathy randomised to 20 and 100 ms PRP under topical 0.4% oxybuprocaine. A masked grader used a pain questionnaire within 1 h (numerical pain score (NPS...

Late residual pulmonary sequel following kerosene burns.

Sudden severe visual loss associated with peripapillary burns during panretinal argon photocoagulation.

A 31-year-old woman lost central visual acuity in her left eye during scatter argon laser photocoagulation when her ophthalmologist treated the temporal peripapillary region. There was no evidence for a vascular explanation. Previous experimental work showed that the lateral spread of thermal energy into the optic nerve parenchyma from the peripapillary pigment epithelium and choroid can destro...

Regional retinal blood flow reduction following half fundus photocoagulation treatment.

Regional changes in retinal blood flow following inferior and subsequent superior argon laser half fundus photocoagulation treatment were measured in six diabetic patients with advanced retinopathy. Centreline blood velocity, vessel diameter, and blood flow in major inferior and superior temporal retinal arteries were measured at baseline and following each treatment using the bidirectional las...
