Purpose: To evaluate the quality of life (QoL) in patients with quiescent herpes simplex keratitis compared with control patients without ocular herpes., Design: Prospective, case-control study., Participants: Thirty-three patients with a unilateral and relapsing herpes simplex keratitis (HSK group) that was quiescent during evaluation (no acute episode in the past 3 months) and 66 patients with no history of HSK (control group). Both groups were age and gender matched., Methods: Three previously validated QoL questionnaires were used in this study: the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25), Glaucoma Quality of Life 17 (Glau-QoL17) questionnaire, and Ocular Surface Disease Quality of Life (OSD-QoL) questionnaire. Each questionnaire covered various aspects of the disease., Main Outcome Measures: The outcomes of the 3 questionnaires were compared between groups. For the HSK group, the results were correlated to the clinical findings and the history of herpetic disease., Results: The mean total questionnaire scores of the 3 QoL questionnaires were significantly lower in the HSK group compared with controls (NEI VFQ-25: 70.5±3.8 vs. 91.1±0.8, P < 0.0001; Glau-QoL17: 68.2±3.1 vs. 87.9±1.0, P < 0.0001; and OSD-QoL: 65.4±2.9 vs. 93.1±0.6, P < 0.0001, respectively). In the HSK group, the level of visual acuity (VA) in the affected eye had the greatest impact on QoL, inducing lower QoL results related to "general vision," "distance activities," "dependency," "peripheral vision," "self-image," "daily living," and "driving" dimensions. Decreased VA in the unaffected eye also negatively affected "self-image" and "driving" results. Patients with frequent HSK relapses had lower QoL related to "ocular pain" and "acknowledgement.", Conclusions: Even during a quiescent phase of the disease, unilateral and relapsing HSK significantly impairs the QoL of patients to a similar level as most sight-threatening diseases. The decrease of VA has the greatest overall effect, but other factors also significantly affect QoL, such as the frequency of relapses., (Copyright © 2016 American Academy of Ophthalmology.

Purpose: To assess the impact of recurrent unilateral herpetic keratitis (HK) on the tear secretion of the unaffected fellow eye., Design: Prospective, noninterventional study., Participants and Controls: Thirty-five patients with a history of recurrent unilateral HK (clinically quiescent for at least 3 months) (HK group) and 35 patients who were age- and sex-matched with no history of corneal disease (control group)., Methods: Tear osmolarity, tear instability (tear break-up time [TBUT]), tear reflex (Schirmer's I test), and central corneal sensitivity with the Cochet-Bonnet esthesiometer (Luneau, France) were measured in the HK and control groups., Main Outcome Measures: Tear osmolarity, TBUT, Schirmer's I, and central corneal sensitivity were compared between the affected and unaffected eyes of the HK and control groups., Results: Tear osmolarity and tear secretion reflex were similar between the affected and unaffected eyes of the HK group. Corneal sensitivity and TBUT were statistically lower in the affected eyes compared with the unaffected eyes in the HK group (P = 0.001 and P<0.001, respectively). The central corneal sensitivity of unaffected eyes in the HK group was not significantly different from that in the control group (P>0.05). The tear stability and tear secretion reflex were decreased and tear osmolarity was increased in the unaffected eyes of the HK group compared with the control group (P<0.05, all cases). The difference between unaffected and control eyes varied according to the type of HK. All 4 tests were modified in patients with neurotrophic keratitis (KN). In the keratouveitis subgroup, only corneal sensitivity was normal, whereas Schirmer's I results were also normal in patients with archipelago keratitis. Tear osmolarity was consistently affected in both eyes of herpetic patients., Conclusions: Tear function is impaired in the unaffected eyes of patients with unilateral recurrent HK, even when the disease is apparently quiescent. The higher severity of results in the unaffected fellow eye of patients with KN in comparison with other herpes subgroups suggests that recurrent HK induces a reduction in the afferent pathways of the tear secretion reflex from the affected eye, leading to tear dysfunction in the unaffected eye., Financial Disclosure(s): The author(s) have no proprietary or commercial interest in any materials discussed in this article., (Copyright © 2013 American Academy of Ophthalmology.
