Correlation between peak intraocular pressure following water drinking test and pulsed methylprednisolone therapy

Steroids have long been known to cause increased intraocular pressures (IOP) in susceptible patients. Intravenous methylprednisolone is used to treat many rheumatological conditions and one of the risks is raised intraocular pressure. It would be useful to find patients at...

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...

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...

Investigation of blood platelet parameters in anterior ischaemic optic neuropathy

The aim of this clinical retrospective comparative study was to assess the possible relationship between arteritic anterior ischaemic optic neuropathy (AAION) and non-arteritic anterior ischaemic optic neuropathy (NAION) with blood platelet parameters and neutrophil-to-lymphocyte ratio (NLR). The medical records of...

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....

Lang Stereopad comparisons

The aim of this study was to compare the effectiveness of the Lang Stereopad in detecting and measuring stereopsis in a population with normal visual parameters. The Lang Stereopad was compared directly to the Frisby, TNO and Lang II stereotests...

Do patients with prolactinomas using dopamine agonist drugs have autonomic dysfunction?

This prospective study aimed to determine whether there is autonomic dysfunction in patients with prolactinomas using dopamine agonist (DA) drugs by measuring static and dynamic pupillary responses using an automatic pupillometric device.Included were 25 eyes from 25 patients who were...

Macular measurements for amblyopic eyes

This study aimed to evaluate the macular parameters including foveal avascular zone (FAV) size and vessel density in amblyopia vs fellow eyes. The study included 23 unilateral amblyopia children (9.86 ±3.12 years; 52.2% female) and non-amblyopia control eyes (8.67 ±2.06...

New management algorithm for acute post cataract endophthalmitis

In this study, the authors aimed to establish an objective algorithm for recommending urgent pars plana vitrectomy (PPV) to help improve visual outcomes in the current era of clear corneal-incision phacoemulsification and small gauge PPV. This study examined 150 cases...

Combined in-office and home-based eccentric viewing training for central vision loss

This retrospective study aimed to investigate the effectiveness of an eccentric viewing training (EVT) programme delivered in a real-world setting (home exercises) by combining a traditional EVT technique with biofeedback training using microperimetry. The authors investigated potential relationships between visual...

OCTA optic disc measurement differences between glaucoma and pituitary macroadenoma

This prospective case-control study aimed to assess the potential of optical coherence tomography (OCT) and OCT angiography (OCTA) in distinguishing between glaucoma and pituitary macroadenoma based on optic disc appearance. Thirty-one patients (23 with glaucoma, eight with pituitary macroadenoma) were...

Diagnosis and management of paediatric keratoconus

This article reviews the current literature on paediatric keratoconus diagnosis and management. Paediatric cases pose challenges as they may not vocalise unilateral changes, difficulty in obtaining reliable imaging, faster rates of progression, difficultly with contact lenses and presumed worse outcomes...
