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)...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Diclofenac versus Bromfenac after cataract surgery

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used after cataract surgery to reduce inflammation and cystoid macular oedema (CMO). Diclofenac 0.1% is used three to five times daily for 28 days and Bromfenac 0.09% twice daily for 14 days postoperatively. The...

Tear production levels and dry eye disease

Dry eye disease (DED) is multifactorial, caused by an alteration in the quality or quantity of tear film’s three layers. Several tests are available for diagnosis. The aim of this study was to determine if the Schirmer test (ST) could...

Vitrectomy in retinal detachment associated with choroidal detachment

Hypotony, posterior retinal breaks, longer axial lengths and total retinal detachments (RD) are risk factors for development of RD associated with choroidal detachment (RRDCD). This study retrospectively analysed the anatomic outcomes and prognostic factors of vitrectomy in 175 patients with...

How are pigment dispersion syndrome and pigmentary glaucoma inherited?

This single centre prospective, cross-sectional study assessed the relatives of patients with pigment dispersion syndrome (PDS) and pigmentary glaucoma (PG) to determine the heritability of these conditions over an 11 month period. One hundred and one unrelated patients with PDS...

Lens surgery in patients with lens subluxation misdiagnosed as primary angle-closure glaucoma

Lens subluxation can be caused by many conditions including Marfan syndrome and other hereditary conditions, and blunt trauma. Lens displacement can cause pupillary block and angle closure. This is commonly misdiagnosed as primary angle closure glaucoma (PACG), which can lead...

Glaucoma and capillary perfusion

Elevated IOP is important but not the sole factor responsible for retinal ganglion cell (RGC) death and optic nerve damage in glaucoma. There is increasing evidence that visual loss correlates with macular inner retinal thinning. A total of 148 eyes...

Amblyopia treatment

This study was conducted to assess practice preferences in the management of amblyopia among paediatric ophthalmologists. A close-ended multiple choice questionnaire consisting of 10 questions was circulated to 113 paediatric ophthalmologists and fellows of which 74 completed the questionnaire. Seventy-six...

Control of bleeding with diabetic vitrectomy under air

The authors describe a modified diabetic vitrectomy using continuous air infusion in diabetic eyes with severe fibrovascular proliferation. In their case series of 25 eyes (20 patients), intravitreal bevacizumab (1.25mg) was used one week prior to surgery. Fifteen eyes had...

Intraocular pressure reduction after cataract surgery

Several studies have shown the efficacy of cataract surgery in lowering intraocular pressure (IOP), especially in angle closure glaucoma compared to open angle. A total of 156 eyes of 109 patients (without glaucoma or with medically controlled glaucoma) were included....

Biometry measure after cycloplegia

The authors investigated optical biometry in an Indian paediatric population on normal and cataract paediatric eyes and studied the effect of cycloplegia on different parameters measured in these eyes. This was a prospective study of 76 eyes aged five to...
