“…The surgery is reported to alter the proprioceptive feedback loop, and this results in a damping of the nystagmus. In 2016, a small prospective randomized trial was performed by Singh and colleagues 8 comparing retroequatorial recessions (group 1) to the tenotomy with reattachment procedure (group 2). Neither group showed a significant improvement in logMAR visual acuity (group 1, 0.6-0.5 [P 5 0.32]; group 2, 0.8-0.8 [P 5 1]), but all patients reported a subjective improvement in visual function.…”

Strabismus is one of the most challenging subspecialties encountered in the field of ophthalmology. The concept of etiology of strabismus is being advanced with the development of newer imaging modalities and increased understanding of the genetics of strabismus. Imaging is also being used to aid in the planning of strabismus surgery. Newer horizons are being explored in the amblyopia management. The good old eye-pad is being replaced with the iPad. Early detection of loss of stereopsis is being used to decide the timing for strabismus surgery. Improvement of binocular summation has been discovered as a benefit of corrective strabismus surgery. Newer surgical techniques such as new transposition procedures are being developed to correct complex strabismus. Strabismus surgeries aided by adjustable sutures have increased the precision of a strabismologist. A new light has been thrown on the psychosocial impact of strabismus. A present-day strabismologist has advanced from the goal of ocular alignment to a bigger perspective “to regain the paradise lost: stereopsis.”

Purpose: To test the hypothesis that a systematic, combination treatment of patients with oculocutaneous albinism type 1 (OCA 1) results in improvement in multiple measures of visual and ocular motor function.Methods: This is a prospective, interventional case series analysis of clinical and electrophyisological data before and after multimodal visual system therapy in 85 patients with OCA 1 who had no previous treatment. Therapy included a three step approach after adaptation to spectacle correction: 1) extraocular muscle surgery, 2) contact lens correction, 3) oral baclofen (Lioresal R ). Outcome measures included: 1) routine demography and clinical characteristics, 2) binocular best-corrected visual acuity in the null position (BVA), 3) gaze dependent visual acuity (GDVA), 4) primary position strabismic deviation (SD), 5) anomalous head posture (AHP), 6) contrast sensitivity function (CS), and 7) the expanded nystagmus acuity function (eNAFX). All patients were followed at least 12 months. Parametric and nonparametric statistical analysis of outcome measure data above pre-and post-treatment were perfomed using standard software on grouped data using computerized software.Results: Patient age ranged from 3.6 to 43.1 years (average 16 years). 63% were male. Follow up ranged from 12-50 mos (ave 15.1 mos). 7% had an associated systemic diagnosis, 95% had a significant refractive error, 88% percent had an AHP, 36% had a periodic or aperiodic component to their nystagmus. 97% had strabismus. There were no serious complications from surgery with a reoperation rate of 12%. There were signficant post treatment improvements in mean/median group BVA, GDVA, SD, AHP, CS, and eNAFX. Conclusion:This study supports the hypothesis that using a combination of standard optical, medical and surgical treatments in patients with OCA1 will result in improvements in multiple aspects of ocular motor and visual functions.Synopsis: This study demonstrates how using a combination of standard medical, optical and surgical therapy results in improvements in ocular motor and visual functions in patients with OCA1.
