Leukaemic Optic Neuropathy in a Patient with Treated Acute Lymphoblastic Leukaemia: Optical Coherence Tomography as an Aid to Diagnosis.

Leukaemic optic neuropathy is an uncommon cause of visual loss which represents a neuro-oncological emergency with the potential of irreversible blindness if untreated. It can be difficult to diagnose, often presenting with normal neuroradiological and cerebrospinal fluid findings. We present the case of a 26-year-old woman with T-cell acute lymphoblastic leukaemia with optic neuropathy secondary to leukaemic infiltration, who demonstrated features on optical coherence tomography that aided the diagnosis of this condition.

Comparative Evaluation of Intraocular Lens Power Calculation Formulas in Children.

Introduction With the advent of newer microsurgical techniques, the results for cataract surgery have become quite promising. An accurate intraocular lens (IOL) power calculation is one of the most important factors in optimizing the results. The aim of this study was to evaluate the accuracy of four IOL power calculation formulas, namely, Barrett Universal II, Holladay 1, SRK/T and Hoffer Q, using optical biometry in children undergoing cataract surgery with primary IOL implantation.

Retropupillary iris claw lens versus Gore-Tex assisted scleral fixated intraocular lens in children with large lens subluxations.

Purpose: To compare the functional outcome of retropupillary iris claw lenses (RPIC-IOL) and scleral fixated intraocular lenses (SFIOL) in children with large lens subluxations.

Methods: Sixty eyes of patients between 6 and 18 years of age having >7 clock hour lens subluxation were included and equally divided into group A (RPIC-IOL implantation) and group B (Gore-Tex sutured SFIOL implantation). Cases with anterior and posterior segment abnormalities, trauma and glaucoma were excluded.

Surgical outcomes of plication versus resection in basic type of intermittent exotropia.

Objectives: To compare the surgical outcomes of plication versus resection in basic type of intermittent exotropia.

Design: Prospective interventional study.

Participants: 60 patients above 6 years of age with diagnosis of basic type of intermittent exotropia.
