PURPOSE: The purpose of this study was to compare the effect of sympathomimetic or anticholinergic psychotropic drugs (tricyclic antidepressants, selective serotonin reuptake inhibitors, and benzodiazepines (TCADs, SSRIs, and BZDs)) with that of non-sympathomimetic/anticholinergic drugs (lithium) on intraocular pressure (IOP) and angle parameters.
METHODS: The study was conducted at a tertiary health care center in South India from December 2023 to February 2024. Seventy-two stable patients (>18 years) on long-term psychotropic therapy (>6 months duration) were recruited by consecutive sampling from the psychiatry department follow-up clinic and divided into two groups: Group 1 (TCADs, SSRIs, and BZDs) - 50 patients; Group 2 (lithium) - 22 patients. The primary outcome was differences in the two groups for IOP, angle appearance by gonioscopy, and angle measurements with anterior-segment optical coherence tomography (Cirrus HD-OCT) by masked observers in only one eye of each participant.
RESULTS: There was no significant difference in IOP between the two groups. A significantly greater proportion of patients in the group on TCADs, SSRIs, and BZDs had narrower angles than the lithium group (P = 0.045) on gonioscopy. On AS-OCT, the mean scleral spur angle in Group 1 patients was 28.38° ± 7.62° and in Group 2 was 36.23° ± 8.08° (P < 0.001). The angle opening distance 500 (P = 0.001) and trabecular iris space area (P = 0.003) were also significantly lower in Group 1.
CONCLUSION: Our study shows that patients on psychotropic drugs (TCADs, SSRI, and BZDs) with sympathetic/cholinomimetic effects have narrower angles than those on lithium and may be at risk of developing angle closure glaucoma.
