Clinical Manifestations and Long-term Outcomes of Endothelial Keratoplasty in Patients with Proven VZV-related Endothelial Decompensation.

Purpose: To report the clinical manifestations, postoperative complications and long-term outcomes of endothelial keratoplasty in VZV-related endothelial decompensation.

Methods: In this retrospective study, thirteen eyes undergoing endothelial keratoplasty (EK) for VZV-related endothelial decompensation were compared with controls for Fuchs endothelial dystrophy or pseudophakic bullous keratopathy.

Results: Twelve patients did not have typical dermal pain or blisters. Ten patients had obvious iris abnormalities. Glaucoma was noted in eight patients before surgery. The best spectacle-corrected visual acuity improved from 1.12 ± 0.47 to 0.39 ± 0.43 (p = .002), whereas endothelial cell (EC) loss was 65% ±15% at 12 months that higher than that in the controls (p < .05). Postoperative complications included graft detachment (2/13), recurrence of endotheliitis (3/13), neurotrophic ulcer (1/13) and scleritis (1/13).

Conclusions: The onset of VZV-related endothelial decompensation is generally insidious. Iris segmental atrophy, glaucoma and pigment KPs are highly suspected to be associated with VZV. EK is a reasonable option to rehabilitate vision.
