Ophthalmological characteristics of strabismic participants in the subject family
| Identifier | Age at examination (years) | Type of reported strabismus | Reported age of onset | Eye movement full | Prism cover test measurements | Visual acuity and refractive status | Strabismus surgery | Other ocular conditions |
| 001* | 24 | Accommodative left esotropia with an A pattern | 9 months | Y | Without correction, there was a 25 PD left esotropia. With correction, there was a 20 PD left esotropia in the primary position. This increased to 30 PD in upgaze and decreased to 10 PD in downgaze | Visual acuity was 20/20 in the right eye and 20/20–3 in the left eye with correction. Wearing: +2.50+3.25×20° OD, +2.25+3.00×135° OS | Bilateral strabismus surgery at age 2 and at age 3; botulinum toxin injection at the age of 4 | |
| 002* | 60 | Hypotropia and left exotropia. Consecutive exodeviation after initial esotropia surgery | Unclear | Y | 20 PD left exotropia. 15 PD of left hypotropia in the primary position | Visual acuity was 20/20–2 OD, 20/20–1 OS with correction. Wearing: −3.50+0.50×50° OD, −4.50+0.75×90° OS | Strabismus surgery at ages 3, 8 and 16 | |
| 004* | 82 | Right esotropia | 3 years | Y | 12 PD comitant esotropia | Visual acuity was 20/200 right, 20/20 left with correction: −1.00+1.75×55° OD, −1.00+2.00×80° OS | Strabismus surgery at ages 7 and 10 | Bilateral senile cataract, right dense amblyopia |
| 007 | 83 | Hypertropia | Unclear | Y | Poor fixation from reduced visual acuity in the left eye due to age-related macular degeneration precluded cover testing | Visual acuity was 20/30 OD, 20/800 OS with correction. Wearing: −1.50+2.00×100° OD, −0.50 OS | Yes. But no time specific information provided. | Macular degeneration left eye, macular drusen right eye. Bilateral senile cataract |
| 009* | 76 | Right superior oblique muscle palsy; excyclotorsion | After age of 2, exact onset time unclear, aware of ocular misalignment at the age of 9 | Y | 8 PD right hypertropia which increased on right head tilt and decreased on left head tilt | Visual acuity: 20/20 right and left corrected: −0.50+1.00×170° OD, −1.25+1.25×35° OS | No | Presbyopia |
| 011* | 14 | Left esotropia | Before the age of 2 | Y | 15 PD left esotropia in the primary position while wearing her glasses. Looking through the top part of glasses at near, her deviation increased to 30 PD. However, when used the near add, reducing the need to accommodate, left esotropia decreased to 15 PD | Visual acuity was 20/20 in each eye with correction. Wearing: −3.25+0.25×0° OD, −3.25 OS. She had an add of +1.50 sphere in each spectacle lens | No | Myopia |
| 013* | 45 | Superior oblique palsy | Unclear, aware of ocular misalignment at the age of 6 | Y | 15 PD right hypertropia in the primary position, increasing to 20 PD on right head tilt, decreasing to 12 PD on left head tilt | Visual acuity: 20/20–2 in each eye with soft contact lens correction | No | Myopia |
| 014* | 72 | Esotropia, right hypertropia; excyclotorsion in both eyes (a history suggests infantile esotropia) | Unclear, patient was informed the strabismus was present since birth | Y | 25 PD esotropia SC at distance/8 PD right hypertropia SC at distance/20 PD esotropia SC at near/4 PD right hypertropia SC at near/Titmus testing results were –/1, –/3 and –/9 | Visual acuity was 20/25 OD and 20/25 OS | 2 strabismus surgeries during 50 s | Senile cataract, latent nystagmus, left eye suppression (self-reported diplopia, but able to ignore it) |
006 did not participate in the clinical study, and no supporting clinical data were available.
*The type of reported strabismus in individuals was confirmed by examination.
