New imaging techniques

To examine the patient and discover the details and extent of vision changes, researchers used new techniques such as optical coherence tomography (OCT) as well as adaptive optics (AO).

OCT, developed in the ’90s and first used to view the retinas of live animals, allows clinicians to see a cross-section of the retina. Today, this technology is used to diagnose many conditions including diabetic retinopathy and glaucoma.

AO allows doctors to study the eye on a microscopic level in real-time. This technology allows clinicians to view individual cones and rods in the retina. AO has led to great strides in our knowledge of retinal function.

These techniques were used to look at the man’s retina at a microscopic level. To look for signs of damage from the high dose of Viagra.

The cones of the patient’s eyes were damaged. Cones are structures in the eye responsible for color vision. The damage to the eyes was similar to inherited retinal diseases such as cone-rod dystrophy and retinitis pigmentosa.

The researchers were surprised by these changes in the patient’s eyes, but the symptoms being experienced are explained by these physical changes.

The scientists are hopeful their observations will be valuable for clinicians when discussing the potential dangers of Viagra (sildenafil citrate) to patients.

As the research is a detailed study of one person, further studies with more participants are needed. Despite this, the study is significant as it illustrates the damage high doses of Viagra can potentially cause.

Although these results are of concern, it’s important to remember that Viagra is used by millions worldwide. It’s rare to experience serious side effects when taken as recommended by a doctor.
