Prostaglandin-Associated Periorbitopathy in Children and Young Adults with Glaucoma.

OBJECTIVE: To evaluate for relative palpebral and orbital changes after long-term unilateral exposure to prostaglandin analogues (PGAs) in patients with childhood glaucoma. DESIGN: Prospective cross-sectional cohort study. PARTICIPANTS: A total of 29 patients with history of childhood glaucoma, who were treated unilaterally with PGAs for at least 12 months. METHODS: Based on 4 standardized clinical photographs (en face with eyes open, right and left side views with eyes open, and en face with eyes closed), 3 masked expert graders each independently selected the eye they perceived to have received unilateral PGA treatment by physical appearance alone and graded the following features relative to the other eye: (1) ocular (e.g., conjunctival hyperemia, iris heterochromia, and buphthalmos), (2) palpebral (e.g., eyelash trichomegaly, eyelash hypertrichosis, eyelid erythema, eyelid edema, eyelid hyperpigmentation, high upper eyelid crease, upper eyelid ptosis, upper and/or lower eyelid retraction, and eyelid skin atrophy with presence of telangiectasias), and (3) periorbital (e.g., superior sulcus hollowing, proptosis, enophthalmos, hypoglobus, and hyperglobus). An interrater reliability analysis was performed using the Fleiss kappa (κ) statistic to determine consistency among raters. MAIN OUTCOME MEASURES: Frequencies of each feature of prostaglandin-associated periorbitopathy (PAP); group consensus; interrater reliability of selected PGA-treatment laterality. RESULTS: Median unilateral PGA exposure time was 31.7 months (interquartile range: 18.8-44.3 months). Eyelash trichomegaly and hypertrichosis (n = 22, 76%), high upper eyelid crease (n = 20, 69%), upper eyelid ptosis (n = 14, 52%), and superior sulcus hollowing (n = 15, 52%) were the most frequently observed features of PAP in PGA-treated eyes compared with untreated fellow eyes. Most of these changes were mild, but 20% to 30% of patients exhibited moderate eyelash and/or eyelid changes. One patient had severe PAP after long-term unilateral PGA exposure. Group consensus with correctly selected laterality was achieved in all patients. The inter-rater reliability was excellent (κ = 0.815, P < 0.001, 95% confidence interval [0.605, 1.000]). CONCLUSIONS: Mild-to-moderate changes in the ocular adnexa can develop in children and young adults with long-term PGA exposure. Patients and their families should be educated on the possibility of PAP, especially when initiating monocular PGA therapy.

Acute Transient Oculomotor Nerve Palsy from Presumed Cavernous Angioma in an Infant.

Cavernous angiomas of the cranial nerves are extremely rare, and those of the oculomotor (third) cranial nerve are rarer still, with no previous cases having been reported in the literature. We report herein the first case of a presumed cavernous angioma involving the subarachnoid portion of the left third nerve presenting as an acute left third nerve palsy in an infant. The child was followed without intervention and the palsy completely resolved. Given the poor functional results with attempted surgical excision and the potential for spontaneous improvement in oculomotor nerve function, it is reasonable to follow patients with these lesions without intervention.

Time Spent in Lateral Sleep Position and Asymmetry in Glaucoma.

PURPOSE: To explore sleep position in asymmetric primary open-angle glaucoma (POAG) with a focus on low pressure glaucoma (LPG). METHODS: Sleep laboratory videos of 54 POAG patients were examined for lateral sleep. Then, 29 LPG patients (intraocular pressure [IOP] < 22 mm Hg) with an intereye visual field index (VFI) asymmetry of more than 5% continuously recorded their sleep position at home for 2 nights by using a portable device. Correlations were sought between sleep position, visual field (VF), and retinal nerve fiber layer (RNFL) symmetry as well as ocular biometric data and positional IOP changes. Finally, an expanded data set of 178 POAG patients (63 LPG and 115 high pressure glaucoma [HPG; IOP ≥ 22 mm Hg]) was used to correlate VF and the RNFL symmetry to the self-assessed sleep position collected in a survey. RESULTS: In the video analysis, patients spent 19% ± 2% (mean ± SEM) more time sleeping on one side than on the other. Right-sided sleep was preferred. Right-sided sleep was 1.6 times more common in continuously recorded home data and correlated to an asymmetric VF that was worse in the left eye (b = -0.422, P = 0.002). Pulse amplitude of left eyes was lower in the right decubitus position (P = 0.02). In the expanded survey, 73% of LPG and 58% of HPG patients slept asymmetrically. Right-sided sleepers had a worse RNFL symmetry score. CONCLUSIONS: Asymmetric sleep behavior is common. Right-sided sleep was preferred and correlated with a lower VFI on the left.
