ABSTRACT To assess the long-term clinical course of dry eye in patients with chronic graft-versus-host disease (cGVHD).
A prospective case series of 49 patients with cGVHD was conducted. Complete history and ophthalmic examination were performed at baseline and at 36 months (range, 26-53). All patients received treatment for dry eye.
Of the 49 participants, 18 (37%) had expired at the time of the 3-year eye examination, 11 were lost to follow-up, 11 declined or were unable to attend the final examination, and 9 (18%) completed the study. There was a statistically insignificant improvement in symptoms of dry eye assessed by the ocular surface disease index [start vs. endpoint: 36 ± 22 (range, 4-72) vs. 30 ± 27 (range, 4-86); P = 0.51]. Visual acuity remained stable at approximately 20/20. Lissamine green staining improved and Schirmer test (with anesthetic) worsened, but neither trend was statistically or clinically significant.
Stable visual acuity, tear production, and lissamine green staining and a statistically insignificant improvement in dry eye symptoms were observed in the 9 participants who completed this 3-year prospective case series of 49 patients with cGVHD. Insofar as these patients represent a minority (18%) of the original cohort, their clinical course may not be generalizable to all patients with cGVHD but may still suggest that this patient population's prognosis could be characterized by stability and excellent vision. Sufficiently powered prospective studies are required to validate these postulates.

    ABSTRACT: Graft versus H\host disease (GVHD) can be a devastating complication following bone marrow transplantation. Acute or chronic systemic GVHD can be lethal, and severe damage of different organs and tissues can occur with both types of GVHD. Ocular involvement, either in an acute or chronic presentation, may range from mild to severe with accompanying vision loss present in 60-90 % of patients. Chronic ocular GVHD, the most common form of GVHD, affects mainly the lacrimal gland, meibomian glands, cornea and conjunctiva, mimicking other immunologically mediated inflammatory diseases of the ocular surface without specific symptoms or signs. However, dry eye disease is the main manifestation of GVHD. The long-term treatment of ocular GVHD continues to be challenging and involves a multidisciplinary approach wherein the ophthalmologist plays a major role. Besides systemic immunosuppression and ocular lubricants, topical steroids and topical cyclosporine are commonly prescribed. Newer therapeutic interventions for moderate and severe ocular GVHD include the use of serum eye drops and scleral contact lenses. In this manuscript, we review the mechanisms, clinical findings, and treatment of ocular GVHD.

    ABSTRACT: Graft-versus-host disease (GVHD) is a common cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Systemic findings involving the skin, gastrointestinal tract, and liver often overshadow the other manifestations of GVHD. Ocular surface disease remains the most common cause of long-term morbidity in GVHD. Herein, the etiology, pathophysiology, clinical manifestations, and treatment of acute and chronic systemic GVHD are reviewed, with a focus on ocular GVHD.

    ABSTRACT: Allogeneic hematopoietic stem cell transplantation (HSCT) has evolved over the past two decades to become the standard of care for hematologic and lymphoid malignancies. Major ocular complications after allogeneic HSCT have been increasing in number and severity. Graft-versus-host disease (GVHD) remains a major cause of ocular morbidity after allogeneic HSCT. The main objective of this review is to elucidate the ocular complications in patients developing GVHD following HSCT. Ocular complications secondary to GVHD are common and include dry eye syndrome, acquisition of ocular allergy from donors with allergic disorders. Eyelid changes may occur in GVHD leading to scleroderma-like changes. Patients may develop poliosis, madarosis, vitiligo, lagophthalmos, and entropion. The cornea may show filamentary keratitis, superficial punctate keratitis, corneal ulcers, and peripheral corneal melting which may lead to perforation in severe cases. Scleritis may also occur which can be anterior or posterior. Keratoconjunctivis sicca appears to be the most common presentation of GVHD. The lacrimal glands may be involved with mononuclear cell infiltration of both the major and accessory lacrimal glands and decrease in tear production. Severe dry eye syndrome in patients with GVHD may develop conjunctival scarring, keratinization, and cicatrization of the conjunctiva. Therapy of GVHD includes systemic immunosuppression and local therapy. Surgical treatment in refractory cases includes surgical intervention to improve the manifestation of GVHD of the eye. This may include tarsorrhapy, prose lenses, punctal occlusions and corneal transplantation.
