Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.6K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Ophthalmic Drug Delivery Systems

211
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

Accessory Structures of the Eye

4.3K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Muscles of the Eye01:20

Muscles of the Eye

5.5K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Area of Science:

  • Ophthalmology
  • Surgical Training
  • Global Health

Background:

  • Ophthalmological care in Cameroon is developing, with established services for cataract and glaucoma.
  • A need exists to expand specialized surgical training, particularly in oculoplasty procedures.
  • The Presbyterian Eye Hospital (Acha) in Bafoussam and Douala serves as a key training center.

Purpose of the Study:

  • To train local Cameroonian doctors in performing common oculoplasty procedures.
  • To assess the feasibility and initial outcomes of oculoplastic surgery training in Acha.
  • To address challenges in establishing oculoplastic surgical services.

Main Methods:

  • A 2-week lectureship funded by the German Ophthalmological Society.
  • Two observational visits to Acha, focusing on patient assessment and surgical training.
  • Performance of various oculoplastic interventions, including lid and socket reconstructions and dacryocystorhinostomies.

Main Results:

  • 96 oculoplastic patients were seen, with 44 surgeries performed over two visits.
  • Common conditions included nasolacrimal duct obstructions, cicatricial ectropion, lagophthalmos, and socket deformities.
  • Successful performance of reconstructive surgeries and dacryocystorhinostomies, with general anesthesia utilized during the second visit.

Conclusions:

  • The training initiative successfully initiated the development of oculoplastic surgical skills among local doctors.
  • Initial challenges were addressed, paving the way for more complex procedures.
  • Ongoing acquisition of instruments and materials, alongside continued training, is crucial for sustained progress in Cameroonian oculoplasty care.
