In 1995, a 46-year-old woman was referred for refractive surgery. Eleven years earlier, she had undergone an uncomplicated penetrating keratoplasty in her right eye to treat a dense corneal opacity caused by contact lens-related microbial keratitis. Due to high myopia in the graft, she was unable to achieve useful vision and declined contact lens use. After extensive counseling, she elected to ...

To demonstrate that the near-point-of-convergence (npc) examination is performed subjectively, visual fixation and four-prism diopter (Δ) base-out (BO) examinations can be conducted with a kiosk-type objective method based on gaze tracking, compared existing method. Objective equipment was used to verify effectiveness. Fifteen adult men women in their 20s 30s (26.87 ± 3.31 years) acuity of 0.8 ...

Study design and setting: An observational cross-sectional study carried out Ghulam Muhammad Maher Medical College (GMMMC) Sukkur from February 2020 to January 2022. Methodology: A Non-probability purposive sampling was used. Inclusion were all individuals attending OP...

PURPOSE To analyze distance and near vision after a nonwavefront-guided Presby reversal treatment targeting a monofocal cornea in a patient intolerant to multifocality in the dominant eye. METHODS Case report. RESULTS An originally myopic patient treated for correcting distance ametropia and simultaneously alleviating presbyopic symptoms resulted in intolerance to the induced multifocality....

PURPOSE The second Cambridge Infant Vision Screening Program examined whether screening for accommodative errors by using videorefraction without cycloplegia could effectively serve as a first stage of screening for refractive errors, measured by standard cycloplegic retinoscopy. The screening also included an orthoptic examination for detection of strabismus. METHODS All infants born in the ...

PURPOSE To assess possible refractive changes according to age and strabismus in a statistically significant cohort. METHODS A population-based sample of 12,534 subjects 0.5 to 20 years old, examined between 2004 and 2006, was tested. Each subject received a complete orthoptic examination, including spherocylindrical streak retinoscopy in cycloplegia. Patients were divided into those with ort...

INTRODUCTION Refractive error is a common cause of amblyopia. OBJECTIVE To determine prevalence of amblyopia and the pattern and the types of refractive error in children with amblyopia in a tertiary eye hospital of Nepal. MATERIALS AND METHODS A retrospective chart review of children diagnosed with amblyopia in the Nepal Eye Hospital (NEH) from July 2006 to June 2011 was conducted. Childre...

Aims: In order to establish normal values and interocular differences of visual acuity, Lea symbols were applied to neurologically and ophthalmologically normal children. Methods: 385 children (21–93 months old) were examined, within a routine check up in an urban paediatric practice where Lea symbol acuity (LS) was measured. Of these children, 90 were re-examined in hospital comparing Lea symb...
