vitreoretinal surgery, when tractional membranes have been excised
or lysed, can prove to be very useful when properly applied.
•
The retina is grossly edematous on the basis of massive leakage of
capillary structures in the posterior regions of the retina. In these
eyes, photocoagulation is usually ineffective in cauterizing the
smaller vessels, and high powers are necessary to obtain any type of
response, most of which is ineffectual.
•
The eye is afflicted with severe renal retinopathy with edema,
intraretinal yellowish serum accumulations, attenuation and
tortuosity of the vascular elements, and general deterioration of the
retina. In these cases, photocoagulation accomplishes little, and
only rarely can decrease the leakage from the small vessels or
alleviate the underlying process.
•
The eye is characterized by diabetic and hypertensive retinopathy
changes that produce massive edema, exudates, areas of capillary
closure, and other components similar to those seen with diabetic
renal retinopathy. In clinical experience, photocoagulation has not
helped posterior polar edema and exudation where the underlying
problem has been advanced hypertension.
