Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

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...
Focusing of Light in the Eye01:16

Focusing of Light in the Eye

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Area of Science:

  • Ophthalmology
  • Surgical Training
  • Refractive Surgery

Background:

  • Academic medical centers play a crucial role in training future surgeons.
  • Evaluating resident surgical caseload and outcomes is essential for quality assurance.
  • Refractive surgery training requires specific metrics to assess competency.

Purpose of the Study:

  • To assess the caseload of residents performing refractive surgery.
  • To compare surgical outcomes between residents and staff surgeons.
  • To evaluate the safety and efficacy of resident-performed refractive surgery.

Main Methods:

  • A comparative case study was conducted at Walter Reed Army Medical Center.
  • Keratorefractive procedures performed by residents between 2002 and 2010 were reviewed.
  • Outcomes (visual acuity, refractive error, complications) of resident vs. staff surgeries (2008-2010) were analyzed.

Main Results:

  • Residents performed 1566 procedures, with caseloads increasing yearly.
  • Postoperative uncorrected visual acuity (UDVA) of 20/20 or better was achieved in 96.1% of resident eyes vs. 94.6% of staff eyes (P=.312).
  • Refractive outcomes (spherical equivalent, CDVA) and complication rates were comparable between resident and staff surgeons.

Conclusions:

  • Resident experience in refractive surgery grew substantially from 2002 to 2010.
  • Resident-performed refractive surgery demonstrated comparable safety and efficacy to that of fellowship-trained surgeons.
  • The findings support the effectiveness of resident training in refractive surgery within an academic setting.
