Correcting Bilateral Astigmatism Restores Children's Reading Fluency

These data support the recommendation for full-time spectacle wear in bilaterally astigmatic students, particularly those with high astigmatism (mean ≥ 3D), as the spectacle correction reading fluency is restored and comparable to non-astigmatic students.

Two OCT Instruments Good for Glaucoma Diagnosis

Our authors found that both the diagnostic abilities of spectral-domain optical coherence tomography (SD-OCT) and time-domain optical coherence tomography (TD-OCT) for outer inferior macular thickness and volume can differentiate between eyes of glaucoma patients and glaucoma suspects with high myopia. These independent predictors had good sensitivity.

Trabeculotomy Consequences in Ocular Biometry

Our authors’ prospective study enrolled 31 eyes from 31 glaucoma patients scheduled for primary trabeculectomy. Axial length and anterior chamber depth decreased 6 months post-operatively and lens thickness increased to preoperative values. They recommend non-contact optical biometry to best facilitate pseudophakic visual rehabilitation.

Multifocal Contact Lenses and Monovision Revisited

Our authors conduct a double-masked randomized crossover trial of four commercially available silicone hydrogel multifocal monthly contact lens designs against monovision. They report that ocular aberration variation between individuals largely masks the differences in optics between current multifocal contact lens designs. The use of different multifocal profiles in the two eyes outperformed monovision, even in early presbyopes.

Scleral Lens Approach to Dry Eye Symptoms?

Our authors found a significantly lower osmolarity and dinucleotides concentration and a significant rise of MMP-9 after short-term scleral lens wear. Moreover, symptomatology of dry eye improved.

Moisture Chamber Spectacles to Treat Dry Eyes?

Our authors suggest moisture chamber spectacles (MCS) significantly relieve dry eye symptoms and impact tear film stability.

Cost Effective Cataract Surgery in AMD

In China our authors find that it is cost effective to provide cataract surgery even in the presence of advanced AMD. Aftewr cataract surgery, the improved quality of life and vision and increased calculated quality adjusted life years (QALYs) justifies surgery.

A Prognostic Approach to Treating Submacular Hemorrhage

The authors studied the treatment outcome of pneumatic displacement and anti-VEGF for wet age-related macular degeneration submacular hemorrhage. They show that higher baseline central foveal thickness and higher hemorrhage reflectivity were correlated with best-corrected logMAR visual acuity 6 months after initial treatment.

Promising Mobility Questionnaire for Severe Vision Loss Interventions

The Independent Mobility Questionnaire (IMQ) is suitable for very visually impaired populations. The authors show the IMQ had excellent measurement precision and the items were well targeted to the level of visual ability in a small retinitis pigmentosa population.

Eye Care in Migrant Camps

Although significant challenges in accessing health care services in refugee and migrant communities have been suggested, there is very little knowledge on eye health status in these communities. The authors' study reports eye health and vision status of a refugee population in a settlement camp in Malawi.

Cognitive and Vergence Abilities Correlated?

The authors believe they provide the first evidence that cognitive capabilities, measured with the Stroop test, correlate with accommodation and vergence abilities.

Ethambutol/Linezolid Optic Neuropathy

This case report describes a 65 year-old male diagnosed with medication-associated toxic optic neuropathy. Interestingly, the patient was consuming multiple medications that could have caused his toxic optic neuropathy, most importantly including ethambutol and linezolid.

Unilateral Accommodation Loss Following Retinal Tear Laser Photocoagulation

Loss of accommodation, especially if unilateral, may represent a serious problem for young people. Unilateral loss of accommodation following a small area laser retinal photocoagulation resulted in the patient stopping work. Full accommodative recovery occurred gradually over 3 months.
