Treat-and-extend comparable to monthly dosing Investigators randomized 60 patients with treatment naïve AMD to treat-and-extend (TREX) dosing or fixed monthly dosing with ranibizumab for 1 year. At 12 months, improvements in BCVA and central retinal thickness were similar between groups, but the monthly group had significantly more injections; 13 compared to 10.1 (range, 7 to 13) (P<0.0001). The mean maximum extension interval between injections after the first 3 monthly doses was 8.4 weeks (range, 4 to 12 weeks). Only 22% of TREX patients required monthly dosing, while 37% could extend treatment to 9-week intervals or longer at month 12. Ophthalmology, December 2015
More evidence linking dry eye and depression Using validated questionnaires, investigators assessed symptoms of dry eye disease (DED) and depression in 53 patients with DED and controls. The association between symptoms of depression and dry eye was linear. DED patients were almost 3 times more likely to have a diagnosis of depression. Depression exacerbated DED symptoms and lead to higher DED symptom scores. However, the mechanisms that underlie the association are unclear. Does DED and its symptoms cause depression through chronic pain or does depression and its medication cause DED? Cornea, December 2015
AS-OCT better predicts angle closure Investigators assessed the incidence of gonioscopic angle closure after 4 years in 277 patients with baseline open angles on gonioscopy but with angle closure (1-4 quadrants) on anterior segment optical coherence tomography (AS OCT), compared with controls who had baseline open angles on gonioscopy and on AS OCT. Among the study group, 17.3% developed gonioscopic angle closure in 2 or more quadrants and 10.1% developed gonioscopic angle closure in 3 or more quadrants, while none of the controls developed gonioscopic angle closure. Additionally, patients with more quadrants of angle closure at baseline were more likely to develop gonioscopic angle closure after 4 years (P < 0.0001). The authors suggest AS OCT is more sensitive, less prone to artifacts and arguably a less subjective method of detecting iridotrabecular contact and angle-closure glaucoma.

Retinal hemorrhage in children unrelated to vaccinations This retrospective study evaluated the prevalence and cause of retinal hemorrhage in 5,177 children seen at a single clinic in Philadelphia. The authors found that 9 children (0.17%) developed retinal hemorrhage, all of whom were diagnosed with abusive head trauma from nonocular findings. Among 2,210 children with immunization records, only 1 developed retinal detachment in the 21 days following vaccinations. The authors suggest considering child abuse as the cause of incidental retinal hemorrhage in children. JAMA Ophthalmology, November 2015
Femtosecond-assisted cataract surgery may reduce phaco time in dense cataracts This prospective study included 240 eyes divided into 4 groups to compare surgery time across cataract grades and between standard and femtosecond-assisted cataract surgery. Laser pretreatment significantly reduced the mean effective phacoemulsification time (EPT) in grade 5 cataracts (P<0.001). Additionally, the EPT for a femtosecond laser–treated grade 5 cataract was most similar to that of a standard-treated grade 3 cataract. The authors conclude that laser pretreatment may reduce complications, such as inflammation and prolonged healing time, in patients with dense cataract.

NEW JOURNAL STUDIES FROM JAPAN (JOS)
Retinal pigment epithelial detachment linked to RPE thinning Investigators evaluated 8 unusual cases of retinal pigment epithelial detachment (PED) with a comorbidity of thinning or nonexistent retinal pigment epithelium (RPE). OCT imaging showed that detachment and thinning corresponded with well-delineated grayish-white lesions at the choroid level through a hypo- or unpigmented area. Hyperfluorescence was detected in these lesions from fluorescein and indocyanine green angiograms, as well as on fundus autofluorescence. The authors suggest that these lesions are possibly a result of focal damage due to longstanding PEDs and may lead to unexpected complications long term. Japanese Journal of Ophthalmology, July 2015

IOP spike common after cyclophotocoagulation This prospective study evaluated the risks associated with IOP spikes following diode laser cyclophotocoagulation. Subjects included in 41 patients (53 eyes) evaluated immediately postop, as well as on days 1, 7, and 90. IOP spikes were common within the first 3 hours: 34% had an increase of ≥3 mm Hg and 18% had an increase ≥10 mm Hg. They authors identified no preoperative or perioperative risk factors and no effect on visual acuity, reduction of glaucoma medication or final postop IOP at 3 months. Still, the authors suggest that a post-laser IOP check is beneficial to detect any significant spikes that may require treatment. Clinical and Experimental Ophthalmology, December 2015
Systemic hydration status broadly affects a variety of ophthalmic conditions This literature review evaluated the influence of hydration status on ocular physiology and morphological characteristics. The authors found ocular diseases were associated with both dehydration (dry eye syndrome, cataract, refractive changes and retinal vascular disease) and excessive hydration (cataract) and hydration status can be estimated using tear fluid osmolarity. They also found that ocular measurements such as central corneal thickness, IOP, axial length and anterior chamber depth can be effected by a patients’ fluid status. The authors suggest that physicians should briefly assess patients’ hydration status prior to interpreting ocular measurements. Clinical and Experimental Ophthalmology, November 2015
