Glaucoma: Overview01:25

Glaucoma: Overview

950
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment

881
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

744
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...

Summary
This summary is machine-generated.

Phacoemulsification cataract surgery (PCS) temporarily increases dry eye (DE) prevalence, particularly mild hypersecretory DE, peaking seven days post-operation. Preoperative ocular surface preparation and eyelid hygiene are recommended due to high pre-existing DE and meibomian gland dysfunction (MGD).

Area of Science:

  • Ophthalmology
  • Ocular Surface Disease
  • Cataract Surgery

Background:

  • Dry eye (DE) and subclinical DE are prevalent in patients undergoing cataract surgery.
  • Meibomian gland dysfunction (MGD) is frequently observed in patients with DE and subclinical DE.

Purpose of the Study:

  • To evaluate the impact of phacoemulsification cataract surgery (PCS) and its associated pharmacological treatments on the incidence of dry eye (DE) related ocular surface changes.
  • To assess the prevalence of DE before and after PCS.

Main Methods:

  • A cohort of 550 cataract patients (age-related and complicated) were evaluated for DE using Ocular Surface Disease Index (OSDI), tear break-up time (TBUT), Schirmer-1 test, and OCT meniscometry.
  • Meibomian gland dysfunction (MGD) was assessed via Norn compression test prior to PCS.
  • Patient assessments were conducted pre-PCS and on days 1, 7, and 30 post-PCS.

Main Results:

  • Prevalence of DE was 51.1% and subclinical DE was 28.9% before PCS.
  • MGD was present in 79.4% of DE patients and 50.3% of subclinical DE patients.
  • Post-PCS, DE prevalence increased significantly on day 1 (58%) and day 7 (63.1%), returning to 55.6% by day 30.

Conclusions:

  • PCS leads to a transient increase in DE prevalence, primarily mild hypersecretory DE, with significant elevations observed on days 1 and 7 post-surgery.
  • The findings suggest that preoperative interventions to normalize the ocular surface and eyelid hygiene are crucial, given the high baseline prevalence of DE and MGD.
