This study reviews the visual outcomes of ten patients under the age of 18 years with craniopharyngioma. The paper also reviews the correlation between visual field (VF) testing and optical coherence tomography (OCT) examination and evaluates the role of OCT...
Anisometropia following cataract surgery and its non-surgical treatment
The desired result of cataract surgery is improved visual acuity without the use of spectacles. In practice most patients following initial cataract extraction are likely to be symptomatic of anisometropia giving rise to prismatic effects (anisophoria) and unequal retinal image...Surgical options for the treatment of hyperopia
The modern refractive surgeon has a variety of options available to treat patients with hyperopia who wish to be independent of spectacles and contact lenses. Unlike in low myopia where presbyopic patients may have the ability to see well for...A missed intraocular telescope – an opportunity to re-focus the evidence

Intraocular telescopes allow magnification of the image so that it would be projected into a larger area of the macula, this makes the central defect caused by dry age-related macular degeneration (AMD) smaller. The most common approach is a Galilean...

Optic neuritis, axonal degeneration, neurofilament protein, retina, tissue
Acute optic neuritis (ON) causes axonal degeneration, which can be quantified from the blood by neurofilament protein (Nf) levels. Within about three months, atrophy of the retinal nerve fibre layer (RNFL) follows. However, it remains challenging to explain why there...

A simple technique for managing eyelid retraction in a patient with an exposed Boston type 2 keratoprosthesis (Kpro)
The article describes a patient with mucous membrane pemphigoid and a Boston type 2 Kpro. In the early postoperative period (one week) inferior skin retraction was noted with exposure of the Kpro and carrier cornea. The exposure was managed by...

EYE - Neuro-ophthalmology
This paper describes the neuroprotective and axon regenerative effects of siRTP801, which is a translatable small-interfering RNA (siRNA) targeting mTOR negative regulator; RTP801, through in-vivo and in-vitro models. In-vivo studies involved an optic nerve crush rat model with intravitreal injections...
