Fluctuating Vision in a Student with Aniridia and Glaucoma
Mateo is a 12-year-old sixth grader with aniridia and secondary glaucoma. His most recent eye report lists intraocular pressures of 26 mmHg in the right eye and 24 mmHg in the left, acuity of 20/100 OD and 20/125 OS in bright light, marked photophobia, and visual fields constricted to about 30 degrees. He currently uses 18-point large print and 2x screen magnification. Over the past three weeks, his classroom teacher reports that he squints, holds worksheets within 4 inches, complains of headaches after 20 minutes of reading, and refuses to copy from the board. His mother mentions that he sometimes forgets his glaucoma drops. The IEP annual review is scheduled in six weeks, and the teacher asks whether to order 24-point materials now or wait for the meeting.
1. What immediate actions should the TVI take, and what should the TVI avoid? Explain the red flags in this situation.

Do not wait for the annual review. The cluster of elevated IOP readings (26/24 mmHg), new headaches, squinting, a working distance of 4 inches, and refusal to copy from the board suggests possible glaucoma progression, inconsistent medication use, or substantially increased glare sensitivity. These are health-related warning signs, not evidence that Mateo is simply being stubborn.
The TVI should: (a) document observations with dates, times, lighting conditions, and task demands; (b) consult the school nurse and request an updated vision report with parent consent; (c) ask the family to contact the ophthalmologist and report the new symptoms; and (d) temporarily reduce visual strain through preferential seating away from glare, copies of board notes, oral instructions, and frequent breaks.
The TVI should avoid changing the prescribed magnification or print size as though it were a medical fix, advising the family to adjust drops, or assuming the behavior is attention-seeking. The TVI cannot diagnose IOP, but can flag a change, collect functional data, and make the learning environment safer while medical follow-up occurs.
2. What data should be gathered before the IEP meeting to decide whether Mateo needs different materials or accommodations, and how should the team use the data?

The team needs functional vision data under the conditions Mateo actually faces: fluorescent classroom lighting, natural light near windows, and dim light. Collect near acuity at 10 inches and at his current 4-inch distance; reading rate and endurance across 18-point, 24-point, and 2x electronic magnification; error patterns; time needed to copy from the board; frequency of breaks; and Mateo's own report of headache and fatigue.
A useful trial would compare at least three conditions over two weeks: 18-point paper, 24-point paper, and a tablet or CCTV with reflow and high contrast. Measure words read correctly per minute, comprehension, page turns, posture, working distance, and minutes before fatigue. Because Mateo has a 30-degree field, simply enlarging print may reduce how much he can see per fixation and increase scanning and page navigation. The team should use the trial data to choose the most efficient access method, not to equate a larger font size with better access.
3. The team proposes ordering all Mateo's materials in 24-point print. Evaluate this proposal.

Ordering 24-point materials is a reasonable temporary accommodation, but it is not sufficient by itself. For a student with photophobia and a constricted field, larger print may improve near acuity while worsening glare, increasing page turns, and reducing the amount of text visible at one time. It also does nothing for board copying, fatigue, or fluctuating IOP.
A stronger plan combines: high-contrast, matte materials with shorter lines; dimmable lighting and glare controls; electronic magnification with reflow so Mateo can enlarge without losing line length; preferential seating; teacher notes or digital board access; and scheduled breaks. The team should pilot 24-point in one content area and compare it with 18-point and electronic access using the data described above. If 24-point is slower or more fatiguing, it should not be adopted universally. The goal is efficient, sustained access, not a single font-size number. The team should also ensure glaucoma monitoring is in place before the IEP meeting.
