The accessory visual structures (or adnexa of eye, ocular adnexa, etc.) are the protecting and supporting structures (adnexa) of the eye, including the eyebrow, eyelids, and lacrimal apparatus.

The ocular adnexa include the eyelids, the conjunctival sac, the lacrimal drainage system, the lacrimal gland, and the orbital contents except for the eye and optic nerve.

Here we will provide a overview of ocular embryology, covering the key stages and events involved in the development of the eye, as well as the genetic and molecular signals that regulate this process.

Adnexa are accessory structures which are involved in protecting and/or supporting the function of an organ. The eye and peri-ocular tissues are extremely specialised.

2023年11月21日 · Ocular adnexa is defined as appendages or accessories of the eye, which are structures adjacent to the eye. Adnexa eye refers to the eyeball accessories that include four main parts:...

Ocular Adnexa presents with various symptoms and causes. Get details on treatment options that may provide relief and promote better health outcomes.

Evaluation of the eye and its adnexa requires a good history, assessment of visual function, and physical examination of the eyes. Occasionally, special examinations or tests may be required to identify specific ocular disorders or to establish the presence of associated systemic disease.

An ophthalmoplastic surgeon is able to identify and correct abnormalities of the ocular adnexae such as ectropion, lid retraction, conjunctival scarring with severe entropion, that can cause secondary ocular surface disorders; manage patients with watering eye, and when needed intervene with a dacryocystorhinostomy by external or endonasal ...

2017年2月11日 · In this chapter, an overview is given of the embryology and normal histology of the human eye and ocular adnexa. This is then followed by an overview of the pathological changes seen in the major diseases of each of the ocular and adnexal structures, with inclusion of our latest genomic understandings of their respective pathogenesis.

2015年3月2日 · The eye can be divided into the ocular adnexa —the structures that surround and support the function of the eyeball—and the structures of the globe of the eye itself: the eyeball. Our binocular vision sends two slightly different images …
