Accommodative loss after retinal cryotherapy

Area of Science:

• Ophthalmology
• Retinal Diseases
• Vision Science

Background:

• Lattice degeneration is a common peripheral retinal finding.
• Cryotherapy is a treatment used for retinal tears associated with lattice degeneration.
• Understanding treatment effects on visual function is crucial.

Purpose of the Study:

• To evaluate the impact of peripheral retinal cryotherapy on accommodative amplitude.
• To assess the recovery of accommodative function post-treatment.

Main Methods:

• Prospective observational case series of 92 eyes from 69 patients.
• Measured accommodative amplitude before and after cryotherapy.
• Analyzed effects based on age, cryotherapy number, and treatment sites.

Main Results:

• No overall significant change in accommodative amplitude.
• Significant temporary decreases observed in patients aged 10-29 years at 1 and 3 weeks post-treatment.
• Acute accommodative loss correlated with increased cryotherapy spots (P = .03).

Conclusions:

• Cryotherapy can cause transient accommodative amplitude reduction, most pronounced in younger individuals.
• Accommodative function generally recovers to baseline by six weeks.
• Higher numbers of cryotherapy spots may lead to greater accommodative loss.
