Phacoemulsification in acute primary angle closure attack eyes led to higher rates of intraocular pressure (IOP) rise and new glaucoma development compared to fellow eyes. Long-term monitoring is crucial even after successful IOP control.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Cataract Surgery Outcomes
Background:
- Acute primary angle closure (APAC) is a serious condition requiring prompt management.
- Phacoemulsification is a common surgical intervention for APAC and cataracts.
- Long-term effects of phacoemulsification on intraocular pressure (IOP) and glaucoma development in APAC eyes require further investigation.
Purpose of the Study:
- To evaluate long-term intraocular pressure (IOP) changes after phacoemulsification in eyes that experienced acute primary angle closure (APAC).
- To assess the incidence of newly developed glaucoma in APAC eyes treated with phacoemulsification.
- To compare outcomes between APAC eyes and their fellow eyes undergoing phacoemulsification.
Main Methods:
- Retrospective chart review of 89 eyes from patients with APAC.
- Comparison of APAC eyes (Group A) versus fellow eyes (Group B) that underwent phacoemulsification within one month of the APAC attack.
- Outcomes measured included IOP rise (>21 mmHg) and new glaucoma development over 12 months.
Main Results:
- A significantly higher cumulative rate of IOP rise was observed in Group A (22.58%) compared to Group B (11.11%) at 12 months (p=0.001).
- New glaucoma developed in 6 patients in Group A, while none were observed in Group B (p<0.001).
- Phacoemulsification in APAC eyes showed a higher prevalence of IOP rise and glaucoma than in fellow eyes.
Conclusions:
- Phacoemulsification in APAC eyes is associated with a greater risk of IOP elevation and subsequent glaucoma development compared to fellow eyes.
- Even with successful IOP control post-APAC and phacoemulsification, vigilance for IOP rise and glaucoma is necessary.
- These findings highlight the potential for long-term complications following phacoemulsification in the context of APAC.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
