Acute angle closure is a rare complication in patients receiving antidepressant treatment. We report two uncommon associations of acute-onset myopia with internal limiting membrane folds and soft exudates following the use of escitalopram. A 28-year-old woman, with no prior history of glasses, taking escitalopram for depression, presented with decreased vision. On examination, she was found to have myopic shift in both eyes and intraocular pressure of 38 mm Hg and 40 mm Hg in the right and left eye, respectively. She had closed angles on gonioscopy; anterior displacement of the iris-lens diaphragm on B-scan and undilated fundus examination revealed soft exudates and inner limiting membrane folds at the macula in both eyes. It is highly important that clinicians be made aware of the risk factors associated with drug-induced secondary acute angle closure with an antidepressant. History taking plays a significant role play in view of any hepatic and renal dysfunction.

Depression is the most common psychological disorder globally including in India. Many large population-based studies in India reported the prevalence to be as high as 73.97 cases per 1000 population. SSRIs (Selective Serotonin Receptor Inhibitors) are the first choice of drugs in the medical management of depression as they are well tolerated, efficacious, and have a better safety profile. Examples include escitalopram and fluoxetine. Human ocular tissues differentiately express mRNA for various serotonin (five- hydroxytryptamine) receptor subtypes. Chidlow G found that serotonin is involved in aqueous humor dynamics and may have a potential role in IOP regulation. Drug-induced bilateral secondary acute angle closure (2° AAC) is an ophthalmic emergency. 2° AAC is caused by abnormal accumulation of fluid into structures behind the iris that causes forward rotation of the ciliary body, iris-lens diaphragm causing myopic shift, shallow anterior chamber, and elevated intraocular pressure (IOP). Withdrawal of the offending agent is central for the successful and timely treatment to prevent visual loss.
This is the first reported case in relation to escitalopram-induced acute angle closure in this region and is an alert for clinicians and nonophthalmologists to be mindful of medications that can potentially precipitate acute angle closure.

Here, we describe a case of 28-year-old woman who presented with the complaint of a sudden decrease in vision along with redness, pain and chemosis and lid edema since 8 days. Five months before presentation, she was started on escitalopram 20 mg/day for depressive psychosis. At the time of presentation, she was admitted in the surgery ward for treatment of viral hepatitis and kidney dysfunction. The patient also had a history of fever, loss of appetite, weakness, and loose stools for eight days. Viral markers including Hepatitis B, HCV, and HIV were negative. On general physical examination, the patient was febrile and pallor was seen. Laboratory investigations revealed deranged liver function tests and renal function tests. On ocular examination, uncorrected visual acuity (UCVA) was <20/400 in both eyes. Best-corrected visual acuity of 20/40 in both eyes with correction of –4.25/–0.75 *70° in the right eye and –4.50/–0.5*80° in the left eye. Slit-lamp examination revealed circumcorneal congestion, mild corneal edema, mid-dilated pupil, and shallow anterior chamber both central and peripheral with forward convexity of the iris-lens diaphragm. IOP with standard Goldmann Applanation tonometer was 38 mm Hg and 40 mm Hg in the right and left eye, respectively. Central Corneal thickness was 546 μm in both eyes. On gonioscopy, angles were closed 360° in both eyes. B-scans revealed anterior displacement of iris-lens diaphragm, choroidal thickening and choroidal effusion [Figure 1]. IOL master 700 was used to document axial length which was 22.46 mm in the right eye and 22.48 mm in the left eye and anterior chamber depth which was OD 2.38 mm and OS 2.33 mm. Fundus examination (mid-dilated) showed internal limiting membrane (ILM) folds and soft exudates in both eyes. Optic nerve head evaluation showed cup: disc ratio of 0.3 in both eyes [Figure 2]. Spectral-domain optical coherence tomography (Spectralis; Heidelberg Engineering, Germany) revealed ILM folds at the macula and infarcts of nerve fiber layer [Figure 3].

Based on the history of the symptoms and clinical presentation, diagnosis of escitalopram induced secondary acute angle closure was made, escitalopram was discontinued. Topical treatment was started with homatropine eye drop twice daily for four days, with dorzolamide 2% plus timolol maleate 0.5% twice daily and prednisolone acetate 1% eye drops four times daily for three days, all of which were tapered gradually over 3 weeks.
On follow-up after 2 days, after stopping escitalopram and starting prescribed treatment, the conjunctival congestion reduced in both eyes, IOP was reduced to 24 mm Hg in the right eye and 28 mm Hg in the left eye. Psychiatrist was advised to shift to some other drug in view of viral hepatitis and bilateral renal parenchymal disease.
| Discussion|| |
Our case describes a patient who presented with sign and symptoms of bilateral secondary acute angle closure with myopic shift with only one identifiable risk factor that is the use of tablet escitalopram for depression. There are cases reported in the literature by Croos, Zelfesky JR, that describe acute angle closure after the use of escitalopram. Escitalopram (75%) is metabolized by CYP hepatic enzymes, and our patient suffered from viral hepatitis which might have led to impaired metabolism of escitalopram leading to an increase in serum concentration of the drug which led to drug toxicity. The case reported by Croos also acknowledged the relationship of concentration of serum escitalopram and precipitation of an attack of AAC. The main mechanism of 2° AAC by anti-psychotic drug is ciliary body effusion leading to anterior rotation of iris–lens diaphragm causing shallow anterior chamber that precipitates AAC. Folds in the inner limiting membrane might give a clue to choroidal effusion as the cause for this presentation. Although cotton wool spots are not commonly associated with glaucoma, they can present in the setting of acute elevation of IOP and may be associated with infarct of nerve fiber layer.
Limitation: nonavailability of anterior segment OCT and ultrasound biomicroscopy. (UBM)
| Conclusion|| |
The use of SSRIs is widespread; thus, it is important for clinicians and nonophthalmologists to be mindful of medications that can potentially precipitate acute angle closure. Ophthalmologists should be consulted to identify risk factors involved.
