Lower postoperative scar height is associated with increased postoperative trichiasis one year after bilamellar tarsal rotation surgery

Bilamellar tarsal rotation has been a key component of the WHO SAFE approach to blindness from trichiaisis (surgery, antibiotics, facial hygiene, environment). The World Health Organisation (WHO) manual describes the procedure as a full thickness blepharotomy placed 3.0mm above and...

Photoscreening comparison

The A09/S09 photoscreener contains a fixation target of flashing lights (as for the S04) plus a smiley face which is new. Concerns were raised that the smiley face may stimulate less accommodation than the S04 attention lights and therefore potentially...

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...

Macular atrophy and choriocapillaris nonperfusion

This Japanese study compared the choriocapillaris (CC) nonperfusion area as measured on OCTA with areas of macular atrophy (MA) measured by fundus autofluoresence (FAF). A total of 44 eyes were assessed (31 were treated with anti-VEGF alone and 13 had...

Vitamin D and thyroid eye disease

This is a retrospective review of vitamin D levels in patients with thyroid eye disease (TED). Vitamin D levels in 89 patients with Grave’s disease and TED were compared against 89 patients with Grave’s disease and no TED. They also...

Topical nonsteroidal ant-inflammatory drugs (NSAIDs) in patients undergoing cataract surgery

Inflammation is a major risk factor for the development of cystoid macular oedema (CMO) after cataract surgery, leading to breakdown of the blood-retina barrier. There is a correlation between severity of CMO and level of postoperative inflammation. Laser flare meter...

Spot screener versus Grand Seiko measurements

The authors aimed to determine repeatability and reproducibility of refractive values and pupil size measured using the Spot Vision Screener and to compare its measurement values with the Grand Seiko autorefractor. This was a cross-sectional study of 22 healthy adults;...

Accuracy of AS-OCT muscle insertion measurements

Anterior segment - optical coherence tomography (AS-OCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of AS-OCT for locating horizontal extraocular muscle insertions after strabismus surgery...

Accuracy of ASOCT muscle insertion measurements

Anterior segment optical coherence tomography (ASOCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of ASOCT for locating horizontal extraocular muscle insertions after strabismus surgery in...

Objective vs. subjective torsion measures

This study aimed to explore the relationship between subjective and objective torsion in normal individuals with no manifest strabismus. The study included 118 eyes of 59 normal people aged >15 years using Heidelberg OCT and the Torsionometer. There were 27...

VA and stereo changes with increasing Bangerter filters

This study investigated the effect of monocular blur induced by Bangerter filters (BF) on both monocular and binocular visual acuity (VA) and stereoacuity in normal visual systems. Subjects included 24 healthy student volunteers aged 20.33 ±1.79 years; 22 female. One...

Optic canal measurements in children

The authors aimed to determine the normal range of optic canal diameters in a Turkish pediatric population. They evaluated 200 CT examinations: 102 females, 98 males with mean age of 86.42 ±65.39 months (range 1-211). There was no significant difference...
