Repeatability, reproducibility, agreement, and safety of Tono-Pen tip cover for intraocular measurement using latex and polyethylene wrap.

Purpose: To evaluate repeatability, reproducibility, and agreement of intraocular pressure measurement with Tono-Pen using Ocufilm and polyethylene wrap tip cover in human eyes.

Methods: This is a cross-sectional, experimental study. A gas-sterilized, polyethylene wrap was used as an alternative for Tono-Pen tip cover.

Diagnostic accuracy of a digital fundus photographic system for detection of retinopathy of prematurity requiring treatment (ROP-RT).

Objectives: To evaluate the diagnostic accuracy of a digital fundus photographic system that consists of taking fundus photographs by a trained technician using a RetCam® shuttle and interpreting fundus images by an expert to detect Retinotapthy of Prematurity requiring treatment (ROP-RT) which defined as type I ROP according to the Early Treatment for ROP study (ETROP).

Materials And Methods: One hundred infants were examined by (1) an expert ophthalmologist experienced in ROP care using indirect ophthalmoscopy; (2) digital wide-field imaging by a trained technician using a RetCam® shuttle and images were sent remotely for interpretation by two ophthalmologists experienced in ROP care (Reader A, and Reader B); and (3) local ophthalmologists using indirect ophthalmoscopy. The diagnostic acurracy consisting of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+), and negative likelihood ratio (LR-) were calculated.

Ocular involvement in melioidosis: a 23-year retrospective review.

Background: Ocular involvement in melioidosis is rare and has devastating outcomes. Although there have been few reports on the condition, Khon Kaen, a city in northeast Thailand, has been called the "capital of melioidosis" due to the high prevalence of the condition in the region. We retrospectively reviewed all admitted cases of melioidosis with ocular involvement from the two largest hospitals in Khon Kaen.

Prevalence of Visual Impairment among 4- to 6-years-old Children in Khon Kaen City Municipality, Thailand.

Objective: To evaluate the prevalence of visual impairment of children aged four to six years in Khon Kaen City Municipality, Thailand.

Material And Method: The visual acuity test was performed on 1,286 children in kindergarten schools located in Khon Kaen Municipality. The first test of visual acuity was done by trained teachers and the second test by the pediatric ophthalmologist.

Comparisons of Amplitude Reduction of Pattern Visual Evoked Potential (VEP) and Flash VEP between Using Srinagarind Eye Patch and Commercial Eye Patch in Normal Subjects.

Objective: To compare the difference of amplitude reduction of pattern VEP and flash VEP between occluding eye with Srinagarind eye patches and commercial eye patches in normal subjects.

Material And Method: Fifteen subjects (7 males and 8 females) who had normal eye examinations were enrolled. Amplitude of pattern VEP was recorded for each individual subject as baseline data.

Health related quality of life instruments for glaucoma: a comprehensive review.

Health related quality of life (HRQOL) outcome is becoming important and of interest for clinicians and patients alike. HRQOL can be affected immediately after the initial diagnosis of the disease through anxiety of blindness. Further impairment in various aspects of HRQOL is expected over time as the disease progresses, reducing daily activities.
