Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE EASTERN DISTRICT OF TEXAS SHERMAN DIVISION

BYRON KEITH TATUM, II § § v. § NO. 4:23-CV-00658-BD § FRANK BISIGNANO § Commissioner, Social Security § Administration §

MEMORANDUM OPINION AND ORDER Plaintiff Byron Keith Tatum, II, seeks judicial review under 42 U.S.C. § 405(g) of a final decision of the United States Social Security Administration Commissioner denying his claim for disability insurance benefits. Having reviewed the transcript of the administrative hearing, the parties’ briefs to this court, and the evidence in the administrative record, the court will affirm the Commissioner’s decision. BACKGROUND A “younger person” at the time of his application, see 20 C.F.R. § 404.1563(c), Tatum applied for benefits based on multiple ailments. AR 99, 342–343, 370. The Commissioner denied his application initially and on reconsideration. At a subsequent hearing before an administrative law judge (“ALJ”), Tatum testified that he had some college education and previously worked in customer service and tech support. AR 35, 44. But then his vision deteriorated and, because of that, his productivity suffered. AR 44. Tatum testified that he had “nystagmus since birth” that caused him “to have low vision.” AR 38; see Nystagmus, Dorland’s Illustrated Medical Dictionary, pp. 1307–08 (32nd ed.) (defining nystagmus as “an involuntary, rapid, rhythmic movement of the eyeball”). Despite surgery and various medications, he continued to experience visual pain and impairment. AR 38–39. As a result of his alleged disabilities, Tatum reported problems completing household chores, driving, grooming himself, and sleeping. Id. When questioned about his ability to reenter the workforce, he stated: “If I didn’t have the vision issue, I would be able to work.” AR 42. After the hearing, the ALJ concluded that Tatum was not disabled within the meaning of the Social Security Act and was therefore not entitled to benefits. His decision, AR 140–149, found that Tatum met several requirements, including establishing the severe impairments of “carpal tunnel syndrome, [nystagmus] and osteoarthritis of [the] thoracic spine,” AR 142. But it went on to find that Tatum: (1) did “not have an impairment or combination of impairments that me[t] or medically equal[ed] the severity of one of the listed impairments in 20 CFR Part 404, Subpart P, Appendix 1”; (2) “ha[d] the residual functional capacity [“RFC”] to perform light work as defined in 20 CFR 404.1567(b)” with certain exertional and visual limitations; and (3) could perform “jobs that exist[ed] in significant numbers in the national economy.” AR 143, 148; see 20 C.F.R. § 404.1545(a) (defining RFC and explaining its assessment and use); id. §§ 404.1545(a)(3), 404.1546(c) (reflecting that an ALJ is responsible for determining a claimant’s RFC at a disability hearing based on all of the relevant medical and other evidence); Social Security Ruling (“SSR”) 96-8p (providing policy guidance regarding assessment of RFC). Tatum asked the Administration’s appeals council to review the ALJ’s decision. It did so and vacated the ALJ’s decision, remanding the case for further administrative proceedings. AR 153– 58. The appeals council based its conclusion on the ALJ’s failure to consider late-provided medical evidence and failure to adequately evaluate Tatum’s mental impairments. AR 154–55. On remand, Tatum testified that his vision fluctuates throughout the day and that he struggles with frequent tripping, depth perception, and eye strain when looking at computers. AR 56. He also testified that, due to his poor vision, his family had been assisting him with cooking, shaving, and differentiating between bottles in the shower. AR 64–65. After the hearing, the ALJ again concluded that Tatum suffered from severe impairments but did not qualify for benefits. AR 162– 74. But the appeals council vacated the ALJ’s decision again. AR 179–84. This time, it faulted the ALJ for conducting an inadequate functional capacity assessment. AR 180. Specifically, it concluded that “the visual limitations assessed in the residual functional capacity [we]re internally inconsistent and impermissibly vague.” AR 181. For that reason, “[r]emand [wa]s required for further consideration of [Tatum’s] visual limitations in vocationally relevant terms based on the evidence as a whole.” Id. On the second remand, Tatum appeared at a third hearing before a different ALJ, Susanne M. Cichanowicz. AR 74. The third hearing centered around Tatum’s alleged visual and mental impairments. Tatum’s attorney noted that Tatum “appears to range above and below the levels of listing in terms of visual acuity.” AR 77. He stated that, as of June 2022, Tatum’s “visual acuity in his worse eye after correction was 20/200 and in his best eye was 20/100” and it appeared that “there [had] been some visual field issues.” Id. He added that Tatum is “limited in a way that isn’t necessarily reflected by . . . ophthalmology testing” because his “eyesight is variable throughout the day” and he suffers “considerable eye strain.” Id. Although Tatum could still see, he had to “blow everything [up] . . . a significant amount” and “limit[] . . . the amount of time that he can look at [a] screen.” Id. He testified that his visual challenges were “constant every day” but that the specific form of struggle changed daily. AR 83. Tatum noted the unpredictability of his condition; he testified that a room’s lighting or his changing mood could impact his vision. AR 84. He recalled trying various medications without success and considered additional surgery. AR 84–85. The ALJ asked Tatum about his cell phone and how he had adapted it to his lifestyle. AR 85. Tatum testified that his family set up audio-based shortcuts, that he used the reader function, and that he utilized screen enlargement. Id. Tatum testified that, since leaving employment, he has spent a lot of his time home-schooling his children. AR 86. He also watches television “every now and then” with the assistance of a magnifying device. AR 86–87. He is “usually able to get through an entire 30-minute show” if he uses the device. AR 87. As of the third hearing, Tatum was learning Braille. Id. His attorney also noted other ailments related to Tatum’s hands, knees, back, and neck. AR 77, 80. Vocational expert Guillermo Pena also testified at Tatum’s third hearing. AR 89. He classified Tatum’s past work as a customer complaint clerk. Id. The ALJ then asked Pena whether a hypothetical person could perform that work if he could: lift, carry, push or pull up to 50 pounds, occasionally, and 25, frequently. Stand or walk for six hours out of an eight-hour day and sit for six hours out of an eight-hour day, occasionally climb ramps or stairs, never climb ladders, ropes or scaffolds, occasionally balance as it’s defined by the DOT, frequently stoop, kneel, crouch and crawl. This individual must avoid hazards such as unprotected heights and fast- moving mechanical parts. The person can perform jobs that do not require operation of a motor vehicle or heavy equipment. The individual is able to perform jobs that require manipulation or handling of objects that are baseball sized or larger and the individual must avoid work tasks that require precise near visual acuity such as needle threading.
