Pseudophakic retinal detachment in high axial myopia

Area of Science:

• Ophthalmology
• Retinal Surgery
• Myopia Research

Background:

• High axial myopia is a known risk factor for retinal detachment (RD).
• Cataract surgery and intraocular lens (IOL) implantation are common procedures, particularly in older populations.
• Posterior capsule opacification is a frequent complication after cataract surgery, often treated with neodymium:YAG (Nd:YAG) laser posterior capsulotomy.

Purpose of the Study:

• To evaluate the incidence of retinal detachment (RD) after extracapsular cataract surgery with IOL implantation in eyes with high axial myopia (axial length ≥ 27 mm).
• To determine the specific risk associated with neodymium:YAG (Nd:YAG) laser posterior capsulotomy in this patient cohort.

Main Methods:

• Retrospective analysis of 386 consecutive cataract surgeries in 275 patients with high axial myopia (axial length ≥ 27 mm) between 1985 and 1993.
• Follow-up via mailed questionnaire in 1994 to ascertain rates of RD and Nd:YAG laser treatment.
• Evaluation of 253 surgical procedures from 190 responding patients.

Main Results:

• The pseudophakic retinal detachment (RD) rate was 0.8% (2 cases).
• Neodymium:YAG (Nd:YAG) laser posterior capsulotomy was performed in 29.2% of eyes.
• Complicated surgeries, including vitreous loss (1.6%), and secondary IOL implantation were noted.

Conclusions:

• Pseudophakia itself presents a minimal additional risk for RD in high axial myopia.
• Neodymium:YAG (Nd:YAG) laser posterior capsulotomy is identified as a significant risk factor for pseudophakic RD.
• Younger age at surgery, complicated procedures, and Nd:YAG capsulotomy are key factors contributing to RD in this population.
