Correlation between Central Visual Field Defects and Stereopsis in Patients with Early-to-Moderate Visual Field Loss.

PURPOSE: To investigate the association between stereoacuity and the presence of central visual field defects (CVFDs) due to glaucoma. DESIGN: A prospective, cross-sectional cohort study. PARTICIPANTS: Participants with early-to-moderate glaucoma with a visual acuity better than 20/40, less than a 2-line difference in visual acuity between eyes, and 2 reliable Humphrey visual fields (VFs) (24-2 SITA standard) with mean deviation (MD) in the worse eye better than - 12 dB. METHODS: Stereoacuity was measured using the Titmus stereo test. Participants with a significant field defect (P < 0.005) in any 1 of the central 4 points in the 24-2 SITA standard total deviation map in either eye were classified as having a CVFD. Vision-related quality of life (VR-QOL) was measured using 25-item National Eye Institute Visual Function Questionnaire scores. Logistic regression was used to determine the associations between the level of stereoacuity and age, sex, race, glaucoma type, presence of CVFDs, visual acuity, contrast sensitivity, and VF MD. MAIN OUTCOME MEASURES: Stereoacuity in the CVFD and non-CVFD groups. RESULTS: Sixty-five participants met the inclusion criteria. The mean age of the participants was 64.3 ± 8.0 years, and 64.6% were women. The median stereoacuity was 60 arc seconds (interquartile range [IQR], 40-120 arc seconds). Forty-two (65%) patients had CVFDs, and 23 (35%) patients did not. The median stereoacuity of the CVFD group was worse than that of the non-CVFD group (60 arc seconds [IQR, 50-140 arc seconds] vs. 40 arc seconds [IQR, 40-80 arc seconds], respectively; P = 0.001). The non-CVFD group had a higher percentage of participants with normal stereopsis than the non-CVFD group (61% vs. 21%, respectively; P = 0.001). A multivariable analysis found that the presence of CVFDs was associated with worse stereopsis levels (odds ratio, 4.49; P = 0.021). The CVFD group had a lower Visual Functioning Questionnaire-25 (VFQ-25) composite score (84.0 vs. 91.4; P = 0.004) and lower VFQ-25 subscale scores for general vision, near activities, and mental health (P < 0.05). CONCLUSIONS: Central visual field defects were associated with increased odds of poor stereoacuity in patients with early-to-moderate glaucomatous VF loss. Specifically, patients without CVFDs are more likely to have normal stereopsis and higher VR-QOL than those with CVFDs. Patients with CVFDs should be counseled regarding how depth perception difficulties may affect daily living.

Non-invasive Respiratory Support and Severe Retinopathy of Prematurity.

The authors describe two premature infants who developed stage 3, zone I retinopathy of prematurity (ROP) with plus disease in both eyes, despite limited exposure to supra-ambient oxygen. Both infants received noninvasive respiratory support for several weeks. Both cases are notable because the ROP was more posterior and aggressive than is typical for the gestational ages or birth weights. These cases are insufficient to make definitive conclusions regarding the factors that cause ROP. Further investigation is required to determine if there is an association between the use of non-invasive respiratory support, even in the absence of supra-ambient oxygen, and severe ROP development.

Ocular Adnexal Acne Agminata: Histopathological and Clinical Case Series.

PURPOSE: Acne agminata has only been rarely reported in the ocular adnexa. This study was undertaken to identify histopathological, clinical, and management features of this disorder. METHODS: A computerized database was utilized to identify cases of ocular adnexal acne agminata. Via chart review and light microscopy, clinical and histopathologic aspects of this dermatosis were collected, and statistical analyses were performed. RESULTS: Twelve cases (5 males, 7 females, mean age = 50.5 years) of clinically and histopathologically confirmed ocular adnexal acne agminata were identified. The main variant of granuloma was sarcoidal in 6 cases (50%) and tuberculoid in 5 cases (41.7%), although 9 specimens (75%) displayed greater than 1 variant of granuloma. In addition, specimens demonstrated varying degrees of fibrosis (8 cases, 66.7%), necrosis (6 cases, 50%), spongiosis (5 cases, 41.7%), and perifollicular inflammation (6 cases, 50%). All specimens showed signs of lymphstasis-lymphangiectasis. At a minimum of 6-month postprocedure interval, all patients experienced complete relief of their symptoms and did not experience recurrence. CONCLUSIONS: This study represents the largest cohort of ocular adnexal acne agminata, and revealed a spectrum of granulomatous subtypes, including coexistence of different granuloma subtypes within the same specimen. Lymphangiectases is a hallmark of this disorder, and varying features of tissue reaction are typical features of acne agminata. All of these cases were successfully cured by surgical resection of lesions without recurrence at last follow-up, and this modality should be considered the standard of care in the management of this problem.
