To determine the incidence and to explore the risk factors for traumatic graft dehiscence after penetrating keratoplasty. ⋯ This case series indicates that there is long-term risk of traumatic wound dehiscence after penetrating keratoplasty. Younger patients, especially males, should be made aware that their eye, after keratoplasty, will always be vulnerable to injury. High-risk situations should be avoided if possible. Older patients at particular risk should have adequate risk reduction strategies, social support, and supervision, in particular to minimize the risk of falls.

The role of the zoster vaccine in the prevention of herpes zoster and its sequelae, including postherpetic neuralgia (PHN) and herpes zoster ophthalmicus. ⋯ The zoster vaccine promises to reduce the morbidity and mortality of herpes zoster. Administering the vaccine at the younger end of the age range may offer a greater cost benefit.

Review
Herpes zoster ophthalmicus natural history, risk factors, clinical presentation, and morbidity.
The incidence and morbidity of herpes zoster (HZ) and HZ ophthalmicus (HZO), and the potential impact of varicella vaccine on their epidemiology. ⋯ Vaccination is key to preventing HZ, HZO, and PHN, but strategies for both varicella and HZ vaccines will need to be evaluated and adjusted periodically as changes in the epidemiology of these VZV diseases become more evident.

Evaluation of evidence-based strategies for managing herpes zoster (HZ) and the pain of postherpetic neuralgia (PHN). ⋯ Options are available to manage HZ and reduce the pain of PHN. However, prevention, now possible with the HZ vaccine, is preferable to treatment.

Comparative Study
Comparison of optic nerve head topography and visual field in eyes with open-angle and angle-closure glaucoma.
To compare the optic disc and visual field (VF) alterations in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). ⋯ When the amount of optic nerve damage is taken into account by adjusting for VF MD or OCT NFL thickness, those with POAG and PACG have no significant differences in optic disc topography. Visual field damage in PACG was more diffuse than that in POAG, as measured by a lower PSD for a given level of MD. There was no corresponding difference in the uniformity of structural damage as measured by OCT NFL thickness.
