Off the Cuff: Hate

Hate is one emotion I am thankfully not very familiar with. There are things and people I don’t much care for, but I don’t dislike anything sufficiently to rouse an emotion I would describe as hate. Maybe because I don’t feel hate myself, I rarely see hate in others. But an encounter with a patient earlier this week brought me face to face with it. The experience was so disturbing, yet so powerful that I felt compelled to share it.

The patient, an elderly Polish woman with a touch of an accent, had come for a routine exam. She was new to our office. Our extern began the exam, but soon called me in to evaluate what he thought were narrow angles. He was right, and anterior segment OCT confirmed the right eye was easily occludable and the left eye not far behind. With asymmetric and elevated pressures and an abnormal GCC in the OD, transient narrow angle closure seemed pretty certain. I explained the condition to the patient, cautioned her about narrow angle attacks and told her that a referral for an LPI was indicated. She was clearly nervous, and I had the feeling she would likely ignore the recommendation.

As I often do with anxious patients, I tried to calm her. I asked what city she was from and joked that I, too, had Polish roots at least part of the time. When she asked what I meant by that, I shared what my father had told me about his country of origin. When I asked where he came from, my dad would always reply “sometimes Russia, sometimes Poland.” The area he was from had changed hands so frequently pre-WWII that his native country depended on the day of the week. The patient laughed at my story and started to open up.

She admitted that she was concerned about the cost of a procedure because she had lost half of her pension after retiring from her state government job. I reassured her that insurance would cover most, if not all, of it and asked why her pension had been cut. She told me that it was because of a woman who hated her. She explained that this bureaucrat had cut the pension and then showed up at every hearing to make sure it wasn't restored. When I asked why this woman hated her so, she looked straight at me, her eyes now filled with a bitter, angry glint that I’ve seen only a few times in my life and she said, “because she is a Jew, and Jews hate the Polish.”

I paused for a brief second before I said loudly, “I am a Jew, and I don’t hate Polish people. I don’t hate anyone.” The look in her eyes turned to panic, then shame and as I gained my composure. I told her, “You shouldn’t blame an entire people for the actions of one individual.” She quickly apologized and shared a story of how her grandmother would smuggle food to help Jews fleeing from Russia during WWII. I nodded as I listened, knowing that her story couldn’t possibly be true. My family was so decimated by the Nazis that my father could never bring himself to speak of it. Sadly, I know that history all too well.

Shaken by what had just happened, I walked the patient to the front desk to arrange for the referral. The woman was clearly embarrassed and when I turned to leave she said, “You must hate me.” I looked right at her and I said, “No, this is not a place for hate, only love,” and I walked away.



Editor’s Note: It is with great sadness that I report the passing of Dick Wallingford. Dick was a friend, a past AOA president and one of the nicest people I ever had the pleasure to know. I worked alongside him as an AOA volunteer, and our paths continued to cross when he joined Vistakon. Dick served the profession with incredible strength despite personal health issues and was a model of what an AOA president should be: selfless, caring and humble. He will be sincerely missed.

Near Binocular Visual Function in Young Adult Ortho-k vs. Soft Contact Lens Wearers
 
 
This study compared near-point binocular vision function of young adult myopes wearing orthokeratology (OK) lenses to matched single-vision soft disposable contact lens (SCL) wearers. A retrospective clinical record analysis of all OK wearers (18 years to 30 years) presenting over an 18-month period was undertaken. Data was extracted for 17 OK wearers, with 17 SCL wearers matched for age, refractive error and duration of contact lens wear. Binocular vision data included horizontal phoria (phoria), horizontal base-in (BIFR) and base-out fusional reserves (BOFR), and accommodation accuracy (AA).

The OK group was 25.8±3.2 years, with a duration of wear of 45.7±25 months and refractive error of R -2.09±1.23D, L -2.00±1.35D. Compared to matched SCL wearers, the OK group were significantly more exophoric (OK -2.05±2.38Δ; SCL 0.00±1.46Δ) and had better accommodation accuracy (OK 0.97±0.33D; SCL 1.28±0.32D). BIFR and BOFR were not different in the two groups. Frequency histograms showed that more SCL wearers had high lags of accommodation (AA≥1.50D: 8 SCL,2 OK) and esophoria (≥1Δ: 5 SCL,1 OK) than OK wearers. A positive correlation was found between refraction and phoria in the SCL group.

Young adult myopes wearing OK lenses displayed more exophoria and lower accommodative lags at near compared with matched single-vision SCL wearers. Researchers concluded that young adult myopes with specific binocular vision disorders may benefit from OK wear in comparison with single vision SCL wear. They added that these findings have relevance for the visual acceptance of OK lenses and management of risk factors for myopia progression.

Stereoacuity After Small Aperture Corneal Inlay Implantation
 
 
The aim of this study was to compare stereoacuity before and after Kamra corneal inlay implantation for the correction of presbyopia. In the prospective study of 60 patients who underwent Kamra inlay implantation, patients were examined before and six months after surgery for stereoacuity, uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA)

The mean stereoacuity before surgery was 29.5±28.1 arcsec (range: 20 to 200) and at six months was 29.8±26.4 arcsec (range: 20 to 200). The decline in stereoacuity was not statistically significant. At six months follow-up, UDVA was 20/25 or better in all 60 patients, and UNVA was J2 (20/25) or better in 51 (85%) patients.

Investigators found no significant change in stereoacuity following Kamra inlay implantation and suggested the inlay could be a good treatment option for improving near vision in presbyopic patients while preserving stereoacuity and distance vision.

Diurnal Intraocular Pressure Variation in Pseudoexfoliation Syndrome
 
 
Investigators prospectively assessed 19 pseudoexfoliation syndrome (PXS) patients (10 bilateral and 9 unilateral) and 25 age- and sex-matched normal subjects to describe and compare the diurnal intraocular pressure (IOP) variation in patients with PXS and normal subjects. One eye of each control subject and bilateral PXS patient was selected randomly, and pseudoexfoliative eyes of unilateral cases were enrolled in this study. All patients were admitted to the investigators’ ophthalmology department and underwent diurnal IOP testing (six measurements over 24 hours).

The mean IOP of PXS patients at all time intervals was significantly higher than the control group. Likewise, a significant difference in the maximum IOP, range of IOP and minimum IOP, as well as the standard deviation of the pressure at each time point, existed between groups. Normal individuals did not show diurnal variation greater than 5mm Hg. Of patients with PXS, 55.6% showed diurnal variation greater than 5mm Hg. In addition, in 10% of patients with PXS, the diurnal variations were equal to or higher than 10mm Hg.

Variations in IOP during the daily 24-hour cycle in patients with PXS were higher than control groups. Investigators wrote that significant fluctuations in the diurnal curve of IOP in PXS may be an important factor in predicting eyes that could develop pseudoexfoliative glaucoma and that IOP fluctuation could influence the diagnostic and prognostic evaluation of PXS.
