Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

987
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

861
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...

Photoreceptors and Visual Pathways

8.2K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Summary
This summary is machine-generated.

Microincision cataract surgery (MICS) provides excellent, stable visual quality for one year. Surgically induced astigmatism decreases over time after MICS, offering improved long-term outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Visual Science

Background:

  • Long-term visual quality after cataract surgery is crucial for patient satisfaction.
  • Microincision cataract surgery (MICS) is a modern technique with potential benefits for visual outcomes.

Purpose of the Study:

  • To evaluate the long-term visual quality, including visual acuity and contrast sensitivity, following MICS.
  • To assess the changes in surgically induced astigmatism (SIA) over a one-year period after MICS.

Main Methods:

  • A one-year study involving 96 patients (144 eyes) with age-related cataracts who underwent MICS.
  • Implantation of aspheric monofocal intraocular lenses.
  • Evaluation of uncorrected distance visual acuity (UDVA), best-corrected distance visual acuity (BCDVA), best-corrected near visual acuity (BCNVA), contrast sensitivity, and SIA.

Main Results:

  • Significant improvements in UDVA, BCDVA, and BCNVA were observed post-surgery and remained stable throughout the year (P < 0.001).
  • Contrast sensitivity also showed significant improvement (P < 0.001).
  • Surgically induced astigmatism (SIA) decreased significantly over the follow-up period, from 0.57 D at 1 week to 0.18 D at 1 year (P < 0.001), with a mean absolute residual diopter of 0.32 D at 1 year.

Conclusions:

  • MICS delivers excellent and sustained visual quality from postoperative day 1 through 1 year.
  • SIA demonstrates a decreasing trend post-MICS, unlike findings in some previous studies, suggesting ongoing visual stabilization up to one year.
