Purpose: To describe the trans-occipital asymmetries of pattern and flash visual evoked potentials (VEPs), in an infant with MRI findings of unilateral optic nerve aplasia and hemi-chiasm dysplasia.
Methods: A child with suspected left cystic microphthalmia, left microcornea, left unilateral optic nerve aplasia, and hemi-chiasm underwent a multi-channel VEP assessment with pattern reversal, pattern onset, and flash stimulation at the age of 16 weeks.
Results: There was no VEP evidence of any post-retinal visual pathway activation from left eye with optic nerve aplasia.

Purpose: To ascertain long-term outcome of treatment for primary epithelial malignancies of the lacrimal gland and compare outcomes after cranio-orbital resection or after macroscopic tumor resection with radiotherapy.
Methods: Comparative case series of 79 patients (49 male; 62%) treated for primary epithelial malignancies of the lacrimal gland at Moorfields Eye Hospital between 1972 and 2014. Patients were identified from clinical and pathological databases and, where available, the clinical, pathological, and imaging records reviewed.
Purpose: To review the long-term corneal complications after high-dose external beam orbital radiotherapy given to patients for lacrimal gland carcinomas. The impact of prophylactic measures to improve long-term ocular surface health is also assessed.
Design: Retrospective case series.

Purpose: To compare, in black Africans and Caucasians, the radiological anatomy of the intranasal structures and lacrimal sac fossa as relevant to dacryocystorhinostomy.
Methods: 0.75 mm section cranio-orbital computed tomography scans from 72 patients (42 black Africans and 30 Caucasian) were included in this retrospective observational case series.
The purpose of this study is to describe the functional and anatomical outcomes of cytomegaloviral retinitis (CMVR) patients undergoing vitrectomy for retinal detachment (RD) in South Africa. In this retrospective case series, CMVR diagnoses were based on clinical examination alone. All vitrectomies were performed by a single surgeon.

Methods: A retrospective, interventional case series of all patients fitting established clinical diagnostic criteria for progressive outer retinal necrosis was conducted at a single institution in South Africa. Eyes with salvageable vision were treated with repeated intravitreal ganciclovir injections until regression was achieved or the eye lost light perception.
