Psychological disturbance in graves ophthalmopathy.

OBJECTIVE: To study mood disturbance in Graves ophthalmopathy. METHODS: Forty-eight patients (mean age, 55 years; 40 women and 8 men) with Graves ophthalmopathy from a university-based referral center were classified into two groups, 24 with moderate/severe disease (study group) and 24 with negligible/mild disease (control group). The groups were matched with regard to demographic and medical characteristics. All participants completed a mood survey to assess differences in degree of emotional distress. MAIN OUTCOME MEASURE: The Profile of Mood States survey, a 65-item self-reported inventory designed to assess emotional distress, was the primary outcome measure. A total mood disturbance score was assigned by summing the scores derived on the 6 subscales of the survey--tension, depression, vigor, confusion, fatigue, and anger. RESULTS: Analysis of variance revealed that patients with moderate/severe Graves ophthalmopathy showed significantly greater emotional distress than patients with mild/negligible Graves ophthalmopathy on the Profile of Mood States mean total score (P<.001). Additionally, patients who had disfigurement (proptosis) as the predominant clinical feature had significantly elevated emotional distress compared with the control group (P = .01), whereas no significant difference was detected between the control group and patients with diplopia as the predominant clinical feature (P = .20). CONCLUSION: Patients with moderate to severe Graves ophthalmopathy have significant mood disturbance, especially when disfiguring signs are predominant. We propose that evaluation of the psychological burden of the disease should be considered in routine follow-up and in decisions regarding treatment.

The relationship between convergence insufficiency and ADHD.

BACKGROUND: Children being evaluated for attention deficit hyperactivity disorder (ADHD) often have an eye exam as part of their evaluation. The symptoms of convergence insufficiency (CI) can make it difficult for a student to concentrate on extended reading and overlap with those of ADHD. METHODS: A retrospective review of 266 patients with CI presenting to an academic pediatric ophthalmology practice was performed. All patients included were diagnosed with CI by one author (DBG) and evaluated for the diagnosis of ADHD. A computerized review was also performed looking at the converse incidence of CI in patients carrying the diagnosis of ADHD. RESULTS: We reviewed 266 charts of patients with CI. Twenty-six patients (9.8%) were diagnosed with ADHD at some time in their clinical course. Of the patients with ADHD and CI, 20 (76.9%) were on medication for ADHD at the time of diagnosis for CI while 6 (23.1%) were either not on medication or the medication was discontinued several months before the diagnosis of CI. The review of computer records showed a 15.9% incidence of CI in the ADHD population. CONCLUSION: We report an apparent three-fold greater incidence of ADHD among patients with CI when compared with the incidence of ADHD in the general US population (1.8-3.3%). We also note a seeming three-fold greater incidence of CI in the ADHD population. This may simply represent an association and not be a causative relationship. Until further studies are performed, however, patients diagnosed with ADHD should be evaluated to identify the small subset that may have CI -- a condition that responds well to treatment at home.

Botulinum A toxin injection for restrictive myopathy of thyroid-related orbitopathy: effects on intraocular pressure.

PURPOSE: To study the effect of extraocular muscle injections of botulinum A toxin on intraocular pressure in patients with thyroid-related orbitopathy. DESIGN: Retrospective observational case series. METHODS: The medical records of eight consecutive patients with restrictive myopathy secondary to thyroid related orbitopathy (TRO) who underwent botulinum A toxin injection from December 1997 to December 1998 were reviewed and analyzed retrospectively. All patients were seen at the University of California, San Diego (UCSD) Thyroid Eye Center, a university-based tertiary referral center. The main outcome measure was intraocular pressure (IOP) readings taken before and after injection in both primary gaze and upgaze (involving one eye in seven of the patients and both eyes in one patient). Intraocular pressure readings were measured by an unmasked physician using a Goldmann applanation tonometer. RESULTS: A statistically significant decrease in IOP in upgaze was noted 2 to 6 weeks following botulinum A toxin injection and in both fields of gaze (primary and upgaze) after 2 to 4 months. The mean IOP before injection was 21.4 +/- 3.0 mm Hg in primary gaze and 29.9 +/- 9.7 mm Hg in upgaze. The mean IOP, following injection at 2 to 6 weeks, was 19.2 +/- 4.2 mm Hg (P <.095) in primary gaze and 25.1 +/- 5.9 mm Hg (P <.023) in upgaze. At 2 to 4 months following injection, the mean IOP was 19.3 +/- 3.9 mm Hg (P <.044) in primary gaze and 27.7 +/- 8.5 mm Hg (P <.024) in upgaze. Six patients indicated improved ocular deviation, which was associated with a lowering of IOP. Two patients indicated no change in IOP or strabismic deviation following botulinum A toxin injection. CONCLUSIONS: Botulinum A toxin injections cause a secondary effect to lower IOP in patients with restrictive strabismus associated with thyroid-related orbitopathy.

Vision testing in the pediatric population.

The goal of office testing of the child remains the same as it is for the adult--to gather as much information as efficiently as possible. Clinical testing of the child requires familiarity with the limitations available tests. Perhaps most important is the ability choose the proper test to use at every development stage. Cooperation may be surprisingly good in to hands of experienced examiners, though very young children can be unpredictable. The general ophthalmologist should not fear having young patients but rather take joy in the interaction with them. Armed with as many tools as possible, the challenge of testing children can be converted to the reward of helping families.

When the darker eye has the smaller pupil.

Waardenburg and congenital Horner syndromes are both recognized causes of congenital hypochromic iris heterochromia. Each has been linked to disruptions in the pathway of tyrosinase induction, thus leading to a deficiency in melanin production of the iris. These syndromes must be considered in the differential diagnosis of a patient presenting with heterochromia iridis. We present the case of a 20-month old boy afflicted with both congenital Horner syndrome and Waardenburg syndrome, type II. In contrast to the more common presentation of congenital Horner syndrome, the affected iris in this case was the darker of the two because of the effects of the concomitant Waardenburg syndrome on the contralateral iris pigmentation. We are unaware of any other cases presenting with both Horner and Waardenburg syndromes and believe that this case serves as an excellent opportunity to briefly review the pathophysiology involved with these disorders.

Prosthetic motility in pegged versus unpegged integrated porous orbital implants.

PURPOSE: To objectively measure and compare prosthetic motility in pegged versus unpegged orbital implants and to determine subjective patient assessment of motility after the pegging procedure. METHODS: A prospective case series of 10 patients with integrated porous orbital implants, who had secondary motility peg placement procedure, were studied. Infrared oculography was used to quantitatively assess pegged and unpegged prosthetic eye motility in horizontal and vertical excursions. RESULTS: For horizontal excursions, prosthetic motility in unpegged implants retained an average of 49.6% of measured motility of the contralateral normal eye, which increased to 86.5% with peg placement (P<0.05). For vertical excursions, prosthetic motility in unpegged implants retained an average of 51.3% of measured motility of the contralateral normal eye, which increased to 54.3% with peg placement (P>0.3). Nine of 10 patients judged their motility as "significantly improved," and 1 patient gave a rating of "some improvement" after peg placement. Four of 10 patients had granulomas around the peg sites. CONCLUSIONS: Objective assessment of prosthetic motility shows a significant increase in horizontal gaze after motility peg placement.

Comparison of the efficacy of combined fluticasone propionate and olopatadine versus combined fluticasone propionate and fexofenadine for the treatment of allergic rhinoconjunctivitis induced by conjunctival allergen challenge.

BACKGROUND: One approach to treating allergic rhinoconjunctivitis is the concomitant use of an intranasal spray such as fluticasone propionate to alleviate nasal symptoms and a topical or systemic agent to relieve ocular symptoms. It has not yet been determined whether a topical or systemic agent is more effective for the latter purpose. OBJECTIVE: This study compared the efficacy of combined use of fluticasone and olopatadine with combined use of fluticasone and fexofenadine in the treatment of the signs and symptoms of allergic rhinoconjunctivitis. METHODS: This 2-site, randomized, double-masked, placebo-controlled, parallel-group study employed the conjunctival allergen challenge (CAC) model, a standardized method of inducing ocular and nasal signs and symptoms of allergic rhinoconjunctivitis. At visit 1, subjects underwent CAC to determine the dose of allergen required to elicit a positive reaction. The allergen dose was confirmed at visit 2, and, according to a randomization schedule, subjects were dispensed fluticasone, olopatadine, and placebo pill; fluticasone, fexofenadine, and tear substitute; or placebo nasal spray, placebo pill, and tear substitute. CAC took place at visit 3, after patients had used the assigned medications for 2 weeks. Study medication was instilled 2 hours before CAC, after which allergic signs and symptoms were graded on standardized scales. The primary efficacy variables were ocular itching, ocular redness, and overall nasal symptoms. RESULTS: Eighty subjects completed the study: 30 received fluticasone and olopatadine, 30 fluticasone and fexofenadine, and 20 placebo. Women constituted 63.8% of the study population and men 36.3%; 91.3% were white, 3.8% black, 2.5% Hispanic, 1.3% Asian, and 1.3% other. Concomitant use of fluticasone and olopatadine produced significantly greater improvements in ocular itching at 3 and 7 minutes after CAC compared with fluticasone and fexofenadine (P < 0.05). There were no significant differences in redness scores between groups; however, concomitant use of fluticasone and olopatadine produced significantly greater improvements in redness at 2 time points in each of the 3 vessel beds (ciliary, conjunctival, and episcleral) compared with placebo, and fluticasone and fexofenadine produced significantly greater improvement in redness at 1 time point in I vessel bed compared with placebo (both comparisons, P < 0.05). The 2 treatments had similar effects on total nasal symptom efficacy scores. CONCLUSIONS: In this study, concomitant use of the topical agents fluticasone and olopatadine was more effective than concomitant use of fluticasone plus fexofenadine for overall treatment of the signs and symptoms of induced allergic rhinoconjunctivitis.

Graded orbital decompression based on severity of proptosis.

OBJECTIVE: To study the results of orbital decompression based on the severity of preoperative proptosis. DESIGN: A retrospective noncomparative interventional case series. PARTICIPANTS: Thirty-nine orbits in 23 patients with thyroid-related orbitopathy at a university-based referral center. INTERVENTION: Graded orbital decompression was performed in all patients based on the severity of preoperative exophthalmometry. MAIN OUTCOME MEASURES: Exophthalmometry, visual acuity, margin-to-reflex distance, prism cover testing, and intraocular pressure. RESULTS: Mean proptosis reduction in all orbits was 6.4 +/- 2.7 mm (P < 0.01). In group 1 (preoperative exophthalmometry <22 mm), proptosis decreased with a mean of 4.8 +/- 1.3 mm (P < 0.01); mean proptosis reduction was 6.0 +/- 2.3 mm (P < 0.01) and 8.9 +/- 3.4 mm (P < 0.01) in group 2 (exophthalmometry between 22-25 mm) and group 3 (exophthalmometry >25 mm), respectively. In four of five eyes with compressive optic neuropathy there was an improvement of best-corrected visual acuity of 2 lines or more. Margin-to-reflex distance of the upper and lower lids and intraocular pressure were reduced in all groups. New-onset diplopia developed in two patients (8.7%); 13 of 15 patients (86.7%) who had diplopia preoperatively had persistent diplopia postoperatively. Two patients (13.3%) had relief of diplopia postoperatively. CONCLUSIONS: Graded orbital decompression based on the severity of preoperative exophthalmometry is useful to determine the type and amount of orbital surgery to be performed.
