Low vision and the risk of dementia: a nationwide population-based cohort study.

Recent studies suggested that an association exists between vision loss and cognitive impairment, although it is still vague whether there are causal relationships or direct association between low vision and dementia. We were to investigate the association between low vision and dementia in the Korean population using the National Health Insurance Service (NHIS) database. We analyzed the data of 6,029,657 subjects aged ≥40 years, drawn from Korea National Health Insurance Service.

Comparison of prelaminar thickness between primary open angle glaucoma and normal tension glaucoma patients.

Main Objective: The thinning of prelaminar tissue and prelamina cupping is known to occur by ischemia, as we see in anterior ischemic optic neuropathy. Since normal tension glaucoma (NTG) is thought to be more related to vascular factor than in primary open-angle glaucoma (POAG), we hypothesized that prelamina thinning may occur prominently in NTG patients. This study investigated the difference in prelaminar tissue thickness between patients with POAG and NTG and verified the factors related to prelaminar thinning.

Interocular retinal nerve fiber layer thickness symmetry value in normal young adults.

Purpose: The aim of this study was to determine the normal range of interocular peripapillary retinal nerve fiber layer (RNFL) thickness symmetry value in young adults. Factors affecting interocular RNFL thickness symmetry were also investigated.

Materials And Methods: Both eyes of 241 ophthalmologically and neurologically normal subjects were scanned using optical coherence tomography (200×200 optic disc cube protocol).

A case of concomitant keratoconus and granular corneal dystrophy type II.

Purpose: We report a Korean case of concomitant keratoconus and granular corneal dystrophy type II.

Methods: Case report.

Results: A 29-year-old man visited our clinic for a routine ocular check-up.

Unilateral lateral rectus advancement with medial rectus recession vs bilateral medial rectus recession for consecutive esotropia.

Background: To compare unilateral lateral rectus (LR) advancement with medial rectus (MR) recession with bilateral MR recession for patients with consecutive esotropia (ET).

Methods: Twenty-nine patients who developed consecutive ET of 30-35 PD following bilateral LR recession for intermittent exotropia were retrospectively reviewed. LR advancement into the original insertion site with 4.
