Transillumination of the angular and frontal veins
American Journal of Ophthalmology
|October 1, 1975
Summary
Fiber optic transillumination accurately maps orbital veins for percutaneous venography. This technique helps surgeons avoid accidental angular vein injury during lacrimal sac surgery.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Medical Imaging
Background:
- Percutaneous orbital venography is crucial for diagnosing orbital vascular conditions.
- Accurate identification of angular and frontal veins is essential for successful venography and surgical procedures.
- Minimizing surgical complications, such as accidental vessel damage, is a priority in orbital surgery.
Purpose of the Study:
- To evaluate the efficacy of fiber optic transillumination for delineating orbital veins.
- To assess the utility of this technique in percutaneous orbital venography.
- To determine if fiber optic transillumination can aid in preventing angular vein injury during lacrimal sac surgery.
Main Methods:
- A 500-W fiber optics cold light source was employed.
- The light was used to transilluminate the angular and frontal veins.
- The technique was applied in the context of percutaneous orbital venography and lacrimal sac surgery.
Main Results:
- Fiber optic transillumination enabled quick and accurate delineation of the angular and frontal veins.
- The method proved effective for percutaneous orbital venography.
- Surgeons were able to avoid cutting the angular vein when operating on the lacrimal sac using this technique.
Conclusions:
- Fiber optic transillumination is a valuable tool for enhancing the accuracy and safety of percutaneous orbital venography.
- This technique offers a significant advantage in preventing iatrogenic injury to the angular vein during orbital and lacrimal sac surgery.

01:11Overview of Systemic Veins
Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...

01:19Veins of Thorax
The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

01:18Veins of the Abdomen and Pelvis
The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

01:19Veins of Head and Neck
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

01:17Veins of Upper Limbs
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

01:15Veins of Lower Limbs
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...
