Assessment for Macular Thickness after Uncomplicated Phacoemulsification Using Optical Coherence Tomography

Area of Science:

• Ophthalmology
• Surgical Outcomes
• Retinal Imaging

Background:

• Macular edema, including cystoid macular edema, is a primary cause of poor visual outcomes post-cataract surgery.
• Optical coherence tomography (OCT) is crucial for evaluating macular thickness and edema.
• Early detection and management are key to improving visual prognosis.

Purpose of the Study:

• To evaluate macular thickness and the incidence of macular edema after uncomplicated cataract surgery.
• To identify risk factors associated with post-cataract surgery macular edema.
• To assess the clinical course of different types of macular edema.

Main Methods:

• Prospective study involving 376 patients undergoing cataract surgery.
• Macular imaging using OCT pre-surgery and at 1 week, 1 month, and 2 months post-surgery.
• Classification of patients into groups based on central macular thickness (CMT) changes and presence of macular edema.

Main Results:

• Macular edema was detected in 9.57% of patients post-surgery.
• Intracameral epinephrine injection during phacoemulsification was significantly associated with macular edema development.
• Statistically significant differences in CMT were observed between groups at 1 and 2 months postoperatively (p < 0.001).

Conclusions:

• Intracameral epinephrine injection may be a causative factor for macular edema after cataract surgery.
• Regular examination of CMT using OCT is recommended for early diagnosis of macular edema.
• Prompt treatment can lead to normal CMT and improved visual acuity.
