SEROTONIN REUPTAKE INHIBITORS MAY REDUCE THE RISK OF RETINAL VEIN OCCLUSION

Area of Science:

• Ophthalmology
• Pharmacology
• Epidemiology

Background:

• Retinal vein occlusion (RVO) is a significant cause of vision loss.
• Understanding risk factors and potential protective agents for RVO is crucial for patient care.
• Serotonin reuptake inhibitors (SRIs) and statins are commonly prescribed medications with potential systemic effects.

Purpose of the Study:

• To compare the incidence of RVO in patients using SRIs versus an age-matched control group.
• To investigate the potential protective association between SRI use and RVO.
• To explore the combined effect of SRIs and statins on RVO risk.

Main Methods:

• Retrospective analysis of electronic health records for patients diagnosed with RVO over a 5-year period.
• Inclusion of an age-matched control group of patients without RVO.
• Statistical comparison using Chi-squared tests and logistic regression to calculate odds ratios (ORs).

Main Results:

• A total of 775 patients were analyzed (283 RVO group, 492 control group).
• Significantly lower rates of SRI and statin use were observed in the RVO group compared to controls (P < 0.001).
• Logistic regression revealed a reduced risk of RVO associated with SRI use (OR 0.39), statins (OR 0.51), and combined use (OR 0.22), all statistically significant (P < 0.001).

Conclusions:

• Patients prescribed SRIs or statins demonstrated a reduced likelihood of developing RVO.
• SRI use appears to be associated with a lower incidence of RVO.
• Combined use of SRIs and statins may offer an additive protective effect against RVO.
