Case Presentation: An elderly female patient with bilateral high myopia and pre-existing myopic foveoschisis underwent uncomplicated sequential cataract surgeries 2 weeks apart. She was able to achieve a satisfactory visual outcome for her left eye with stable myopic foveoschisis and visual acuity of 6/7.

Clinical Study on Corneal Topographical Changes in Vernal Keratoconjunctivitis by Using OCULUS Pentacam®.

Purpose: To evaluate the corneal topographical changes in vernal keratoconjunctivitis (VKC) subjects using OCULUS Pentacam.

Design: This was a cross-sectional study.

Methods: VKC patients and normal subjects who fulfilled the inclusion and exclusion criteria were recruited by convenience sampling into the study.

Review of Evidence for the Usage of Antioxidants for Eye Aging.

Oxidative stress is one of the common factors leading to age-related eye diseases in older adults. Factors such as high oxygen consumption, high concentration of polyunsaturated fatty acids, and cumulative exposure to high-energy visible light in the eyes, lead to excessive generation of reactive oxygen species, hence triggering apoptosis of ocular cells and giving rise to ophthalmic diseases. Dietary supplements such as carotenoids, anthocyanins, and vitamins have antioxidant properties which may be of benefit in retaining better vision or reversing vision impairment; thus, studies have been conducted to understand the role of dietary supplements in the treatment or prevention of ophthalmic diseases.

Bacterial contamination of non-contact condensing lenses in National University of Malaysia Hospital isolated using BD BACTEC Peds Plus/F broth bottles versus conventional culture plates.

Non-contact condensing lenses (NCLL) are a requirement in ophthalmology examinations. To date, there have been no studies on the types of bacteria found on handheld lenses used to examine patients in an ophthalmology clinic. The BD BACTEC Peds Plus broth (BACTEC-PP) culture method can isolate more organisms as compared to conventional culture plates (CCP) from NCLL.

The Relationship Between Choroidal and Photoreceptor Layer Thickness With Visual Acuity in Highly Myopic Eyes.

Purpose: The aim of this study was to evaluate the choroidal and photoreceptor thickness in highly myopic eyes and its correlation with visual acuity.

Methods: This is a cross-sectional, observational study involving 57 eyes of 57 highly myopic subjects [spherical equivalent ≥ -6 diopters (D) or axial length ≥ 26 mm] seen in a tertiary institutional center. Eyes with any clinical evidence of maculopathy or amblyopia were excluded.

A Rare Occurrence of Craniopharyngioma Causing Visual Disturbance in Pregnancy.
