Purpose To evaluate the clinical manifestations and factors affecting onset of strabismus and nystagmus in the congenital cataracts. Methods 148 eyes of the 88 patients who had undergone cataract removal for congenital cataracts between January 1996 year and January 2011 year were reviewed. The age at the surgery was from 6 weeks to 21 years. The factors related with the development of strabismus and nystagmus were analyzed. Results The prevalence rate of strabismus was 28.8% in the bilateral cataracts, and 45% the unilateral cataracts at the last follow‐up. Exotropia was the most common type of strabismus both preoperatively and postoperatively regardless of bilaterality of the cataracts. The same type of strabismus persisted after surgery. Nystagmus was noted in the 18 patients (30.5%) only with bilateral cataracts. Nystagmus was accompanied significantly by strabismus in the 10 patients (55.6%). In the patients with nystagmus, esotropia:exotropia was 4:6 and poor visual prognosis was noted. Strabismus developed more significantly in the patients without primary IOL implantation. Conclusion The factors related with development of strabismus were unilateral cataracts, nystagmus, and aphakic state. Exotropia was the most common type and nystagmus was shown only in the bilateral cataracts.

Purpose To determine the different clinical findings between good and poor prognosis group which is diagnosed with branch retinal artery obstruction(BRAO) and treated with conservative care. We evaluate the average macular thickness, foveal thickness, outer nuclear layer(ONL) on optical coherence tomography(OCT) and retinal artery diameter in both groups. Methods 9 eyes(9 patients) in patients with non‐complicated BRAO with good prognosis and a poor prognosis control group with non‐complicated BRAO of 11 eyes(11 patients) were used in this study. The average macular thickness, foveal thickness and ONL thickness at the center of fovea on OCT were measured. And branch retinal artery widths were measured by a semi‐automated retinal vessel width measurement system retrospectively. Results The average age of the patients was 67.3 ± 11.5 years. The average ONL thickness at the central fovea of the good prognosis group was significantly thicker than that of the control group (p = 0.016). There were no statistically significant result at average macular thickness and foveal thickness. In good prognosis group, Ischemic retinal artery diameter and Central retinal artery equivalent(CRAE) were wider than those of poor prognosis group and they were statistically significant (p = 0.028, p = 0.01). Conclusion In the patients diagnosed with BRAO and treated with conservative care, foveal thickness, ischemic retinal artery diameter and CRAE were statistically significant between good and poor prognosis groups. In the patients diagnosed with BRAO, foveal thickness and retinal artery diameter could be prognostic factors that predict visual prognosis.
