Instances of ocular findings in transgender patients undergoing hormonal therapy

Abstract

Purpose: To describe the ophthalmological manifestations in transgender patients on gender-affirming hormone therapy. Methods: A retrospective chart review study was conducted. Female-to-male (FTM) and male-to-female (MTF) transgenders on gender-affirming hormone therapy evaluated at a single center were included. Candidates were collected using a phrase-identifying search tool within the electronic medical record system. Descriptive analyses were conducted to report the demographics, hormonal therapies, clinical findings, and visual outcomes. Results: A total of 17 patients were included, seven were FTM, and ten were MTF transgenders. The median age was 26.0 years (range; 20.0–30.0) in the FTM group and 35.0 years (range; 23.0–67.0) in the MTF group. Testosterone therapy in FTM patients comprised 30–60 mg of intramuscular injections weekly or 50 mg of transdermal gel daily. MTF patients used mainly 2–4 mg of estradiol and 100–300 mg of spironolactone tablets daily. A total of 27 eyes were affected, 12 in FTM and 15 in MTF patients. The median visual acuity was 20/25 in FTM (range; 20/20-20/60) and 20/25 in MTF (range; 20/20-20/400). The most common diagnoses in FTM patients were neurologic (71.4 %), particularly idiopathic intracranial hypertension, while MTF transgenders presented mainly with chorioretinal diseases (40.0 %). Compliance with medical recommendations and follow-up appointments was seen in 71.4 % of FTM and 50.0 % of MTF patients. At the last visit, the median visual acuity was 20/50 (range; 20/20-20/70) in FTM and 20/25 (range; 20/20-20/70) in MTF patients. Conclusions and importance: Transgenders presented a variety of ocular findings. A cause-and-effect association cannot be stated, yet eye specialists must be cognizant of these findings to provide appropriate treatment.
