OBJECTIVES: To determine the prevalence of chorioretinal lesions and optic
disc edema after heart transplantation and to study potential associations.
DESIGN AND PATIENTS: One hundred one patients who had undergone heart
transplantation at one institution and 19 patients prior to heart
transplantation underwent ophthalmological examination, including fundus
photography. The prevalence of fundus lesions was then compared between the
two groups. MAIN OUTCOME MEASURE: With a standardized protocol, the
presence of optic disc edema, chorioretinal hyperpigmentation and
depigmentation, retinal hemorrhages, cotton-wool lesions, and arteriovenous
nicking was graded on color transparencies. RESULTS: The prevalence of
optic disc edema and hypopigmentations was significantly higher among the
transplant recipients than among the patients prior to heart
transplantation (31% vs 5%, P = .01, and 55% vs 11%, P < .001,
respectively). Hyperpigmentation was only present in patients after
transplantation (15% vs 0%, P = .06). Heart transplant recipients showed an
increased risk of hyperpigmentations after 2.5 years. Acute rejection
episodes were not associated with posterior pole lesions. CONCLUSION:
Common posterior pole lesions after heart transplantation are optic disc
edema and pigmentary changes. Although visual acuity does not seem severely
impaired, further longitudinal study is necessary to evaluate the long-term
significance of these lesions.
