History A 35-year-old male presents with bilateral corneal opacities. Examination shows a honeycomb-type dystrophy. A penetrating keratoplasty is performed and the specimen sent for ophthalmic histopathological assessment. Figure 1 is the haemotoxylin & eosin (H&E). Figure 2 is a Masson...

Pain control during orbital implant surgery

This is a study based on existing evidence that pre-emptive pain control has advantages over traditional post-surgical analgesia. The authors compared pain scores in three groups of randomly assigned and masked patients all undergoing orbital implant surgery under general anaesthesia...

White dot syndromes

It is fair to say that trainees and consultants who are not medical retina specialists are a bit scared of the so called retinal ‘white dot syndromes’. It is easy to understand why this is the case, as almost every...

Essentials of OCT in Ocular Disease

Sir Isaac Newton was the first to establish the technique of low coherence white light interferometry. Following on from this, the principle of laser interferometry as an imaging modality for retina was applied by David Huang and his associates in...

Warfarin Induced Suprachoroidal Haemorrhage Presenting as Acute Angle Closure Glaucoma

Spontaneous suprachoroidal haemorrhage is a rare but recognised entity. Anticoagulant therapy is a well known risk factor. We describe a case of warfarin induced suprachoroidal haemorrhage presenting as acute angle closure glaucoma in a patient with raised International Normalised Ratio...

Displacement of submacular haemorrhage – comparative study pneumatic displacement versus subretinal cocktail injection

The authors report a multicentre retrospective interventional case series study comparing the outcome of submacular haemorrhage (SMH) using pneumatic displacement with intravitreal expansile gas versus treatment with pars plana vitrectomy (PPV) versus subretinal injection of tissue plasminogen activator (tPA), anti-vascular...

A unique case of macular burn from ‘toy’ laser

The first laser was created in 1960 and its name is an acronym for ‘light amplification by stimulated emission of radiation’. Laser technology has been used for medical, industrial, research and entertainment purposes in a variety of fields following extensive...

Deciphering dark retinal patches

We present a case of bilateral extensive dark without pressure (DWP) located outside the retinal vascular arcades in a young female. This retinal finding is benign but, in some instances, darkened retinal patches could be associated with potential sight-threatening conditions....

Complement Factor H and Factor H-Like protein are expressed in human RPE cells

The role of inflammation in age-related macular degeneration (AMD) is well documented and the association of AMD with the inflammatory marker C-reactive protein (CRP) and members of the complement system underline the role of complements in AMD. Human complement factor...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

Migraine attack: does retinal and peripapillary blood flow change?

This prospective clinical study compared retinal and peripapillary blood flow parameters in migraine patients during an attack with healthy controls using optical coherence tomography angiography (OCTA). OCTAs were performed on 52 eyes from 26 migraine sufferers and 48 eyes from...
