The effect of latanoprost on accommodation in young patients with ocular hypertension.

PURPOSE: To determine whether topical latanoprost 0.005% had an effect on accommodative capacity after 1 month of treatment in young patients with ocular hypertension. PATIENTS AND METHODS: Fifteen patients (9 men and 6 women, aged 20-40 years) with ocular hypertension were instructed to instill the drug to their right eye for 1 month; the left eye received no medication and served as control. Near point of accommodation, refraction, and intraocular pressure (IOP) were determined after 1 month of treatment. RESULTS: After 1 month of treatment with latanoprost, the mean IOP was reduced by 22.8% (5.8 mm Hg) in the treated eye and 1.86% (0.47 mm Hg) in the untreated control eye. No significant changes in refraction or near point of accommodation were observed in the treated or untreated eye. CONCLUSION: Short-term treatment with latanoprost 0.005% does not effect refraction or accommodation in young patients with ocular hypertension.

Acute comitant esotropia after cataract surgery.

A 52-year-old woman developed comitant esotropia after cataract surgery. The ocular history was significant for accommodative esotropia; preoperatively, she manifested peripheral fusion with central suppression. Immediately postoperatively, the patient was diplopic with comitant esotropia and was treated with extraocular muscle surgery. The appearance of horizontal strabismus after cataract surgery in patients with a history of accommodative esotropia, especially those with subnormal binocularity, is a possible complication that should be discussed with the patient.

The binocular videorefractoscope for visual screening in infancy.

Photorefraction is a promising technique for screening infants for amblyopiogenic defects, but currently used instruments often produce images that are difficult to interpret due to inaccurate control of the subject's fixation, to the narrow range (+/- 4 D) of the measurable error, to ill-defined crescent borders, and to chromatic aberration. A charge-coupled device (CCD) camera with near-infrared sensitivity connected to a computer with an image grabber for real-time equalization was devised to overcome the aforementioned problems. This binocular videorefractoscope (VRB) enables a dynamic and nondissociating refractive status and an ocular motility testing. Fixation and accommodative response are observed on-line and the strabismic angle is measured off-line. Arrays of infrared-emitting diodes with a variable eccentricity and position reveal sphere and/or cylinder errors (+/- 10 D; null interval, +0.00 to -2 in an 8-mm pupil diameter) as well as squint (> 5 prism diopters) and dioptric media opacities. The VRB was tested during noncycloplegic screening for amblyopiogenic defects in 212 3-year-old children. The findings were compared with the results of manifest and cycloplegic autorefractometry in a blind study. The VRB revealed a sensitivity of 81% and a specificity of 97%. In conclusion, the VRB can give a fast, noninvasive, and reliable evaluation of amblyopiogenic factors in infants.
