Social SecurityEvidence
In one sentence

In O.B. v. Commissioner, Judge Kang remanded the denial of supplemental security income after finding errors in evaluating vision evidence.

Who this affects

O.B. and the Commissioner of Social Security; the case returns to the agency for further administrative proceedings, and O.B. was awarded costs.

What happened

In O.B. v. Commissioner of Social Security, O.B. asked the court to review the denial of supplemental security income. The administrative law judge found that O.B. was not disabled despite blindness in the right eye, post-traumatic stress disorder, and other impairments.

O.B. argued that the administrative law judge improperly rejected his testimony about vision-related symptoms, discounted a medical opinion about his visual limits, failed to develop the record, and omitted mental limitations from the work-capacity assessment. The Commissioner argued that the decision properly applied the law and was supported by the evidence.

Judge Peter H. Kang reversed the Commissioner’s decision and remanded the case for further administrative proceedings. The court found inadequate explanations for rejecting O.B.’s symptom testimony and the medical opinion, and found that the administrative law judge improperly relied on her own medical judgment and failed to develop the record. The court found no error in omitting additional work restrictions for O.B.’s mild concentration, persistence, and pace limitations. O.B. was also awarded costs under Federal Rule of Civil Procedure 54(d)(1).

Case
O.B. v. Commissioner of Social Security · No. 3:24-cv-02611
Judge
Kang
Date
Sept. 10, 2025

Background

O.B. sought judicial review under the Social Security Act of the Commissioner’s denial of his application for supplemental security income. O.B. alleged disability based on blindness in the right eye, impaired vision in the left eye, and post-traumatic stress disorder. After an earlier administrative law judge decision was vacated and remanded by the Appeals Council, Administrative Law Judge Corinne T. McLaughlin held another hearing and issued a decision finding O.B. not disabled.

The administrative law judge found severe impairments consisting of post-traumatic stress disorder, opioid use disorder, cannabis use disorder, and right-eye blindness. She found asthma and hepatitis C non-severe. She determined that O.B. could perform work at all exertional levels with restrictions, including no work requiring peripheral vision on the right or precise near vision, and only occasional interaction with supervisors, coworkers, and the public. At the final step of the disability analysis, she found that O.B. could perform jobs such as agricultural produce packer, day worker, and cook helper.

Issues and Analysis

O.B. challenged the decision on four grounds: the handling of his testimony about vision-related symptoms, the evaluation of Dr. Betty Santiago’s medical opinion, the failure to further develop the record, and the failure to include work restrictions for mild limitations in concentration, persistence, and maintaining pace.

O.B.’s symptom testimony

The court held that the administrative law judge did not adequately explain why O.B.’s testimony about his vision symptoms was rejected. The administrative law judge properly relied on medical evidence showing near-normal vision in O.B.’s left eye, but her other reasons were insufficient.

The administrative law judge relied on O.B.’s limited treatment and minimal follow-up without identifying more aggressive treatment that was available and appropriate or considering why O.B. did not receive more treatment, particularly while incarcerated. The court therefore found those reasons insufficient.

The court also found that the administrative law judge did not adequately explain why O.B.’s ability to read and ride a bicycle contradicted his reported limitations. O.B. testified that he needed large print, could read only for limited periods before resting, and relied on a roommate for transportation and shopping. The administrative law judge did not explain how these activities transferred to workplace tasks or examine the extent and conditions of O.B.’s bicycle riding. The court concluded that the administrative law judge failed to provide the required specific, clear, and convincing reasons for rejecting O.B.’s testimony about his vision-related symptoms.

Dr. Santiago’s medical opinion

Dr. Santiago opined that O.B. had limited right-eye near acuity, far acuity, and field of vision because he had blindness in the right eye and near-normal vision in the left eye. She recommended avoiding work tasks requiring more than occasional visual ability or visual-field ability.

The administrative law judge found this opinion only partly persuasive, describing its limitations as vague and arbitrary and inconsistent with the medical evidence and O.B.’s activities. The court found that reasoning unsupported by substantial evidence, meaning evidence sufficient for a reasonable person to accept the conclusion.

The court held that the administrative law judge improperly called the opinion vague even though it referred to records documenting blindness in the right eye. The court also held that the administrative law judge improperly assumed, without supporting medical evidence, that blindness in one eye could not affect overall binocular vision when the other eye had near-normal vision. The administrative law judge was not qualified to make that medical determination based on her own judgment.

The court further held that the administrative law judge improperly reused the inadequate reasons concerning limited treatment, follow-up, and daily activities to discount Dr. Santiago’s opinion. The administrative law judge also failed to explain how near-normal left-eye findings conflicted with Dr. Santiago’s opinion, which already accounted for those findings.

Development of the record

The court found that the administrative law judge substituted her own judgment for a medical professional’s judgment in assessing O.B.’s work capacity. The record contained Dr. Santiago’s contrary view about the effect of monocular vision on overall binocular vision, while the administrative law judge acknowledged that the record lacked findings about combined vision.

The court also found that the record did not contain evidence about more aggressive treatment options, and that the administrative law judge did not adequately question O.B. about his treatment history or the extent and limitations of his bicycle riding. Because the evidence was inadequate for proper evaluation, the court held that further development of the record was necessary.

Mental limitations

The court rejected O.B.’s argument that the administrative law judge was required to include an additional work restriction for the mild limitations found in concentration, persistence, and maintaining pace. The administrative law judge considered those limitations and relied on O.B.’s testimony that he had no concentration problems and on treatment records generally showing no concentration issues. O.B. did not identify a specific additional work restriction or evidence requiring one. The court found no error on this issue.

Disposition

Judge Peter H. Kang ordered that the Commissioner’s final decision be reversed and that the case be remanded to the Commissioner for further administrative proceedings consistent with the order. The court also awarded O.B. costs under Federal Rule of Civil Procedure 54(d)(1).
